The Other Zero

Whenever a nation has more than one branch of its military, something of a cordial disliking will invariably spring up between them.  For example, here in the US the Army doesn't much care for the Navy, the Navy has a mild distaste for the Army, and nobody likes the Marines.  When it comes right down to it however, all three know they've got to work together and when the time comes, they set aside their rivalries and land on their enemies like a ton of bricks.

And then there was the Imperial Japanese military in World War II.  The Army and the Navy didn't cordially dislike each other, they flat out hated each other.  Each had their own plans on how to conduct the war and only deviated from them when they needed something from the other.  The only reason you couldn't say that, say, the IJN's main enemy was the IJA was that the two services didn't openly shoot at each other.  This open distaste extended to the designs of each forces' aircraft.  While the US Army Air Forces and the US Navy designed planes that were radically different, that's because each service had different requirements.  Strangely, the requirements for the IJN and the IJA were pretty much identical, save for the need for Navy planes to land on a carrier.

Both the Navy and the Army needed replacements for their front-line fighers, the A5M (Claude) and the Ki-27 (Nate), two very similar designs.  Mitsubishi won the design contract for the Navy with the A6M, the famous Zero.  Nakajima's design for the replacement of their own Ki-27 was the Ki-43 Hayabusa.

To say that there was a resemblance to the Zero would be something of an understatement.  Both fighters used the same Sakae radial engine, at least to begin with.  Both were slim, with slightly bent cantilevered wings.  However, the Zero was nearly 700lbs heavier at all-up weight.  This made the Hayabusa (Allied code name "Oscar") even more maneuverable than the already outstandingly nimble Zero.

Unlike the Zero, which passed its initial flight tests with ease, the Hayabusa was something of a dog right off the drawing table.  In fact, the plane was nearly rejected on the grounds of being rather UNmaneuverable.  Over the course of ten preproduction aircraft, the Oscar was modified with a larger wing, had its weight cut, and finally had a set of butterfly (or "combat") flaps installed.  This proved to be the fix the fighter needed, and it was ordered into mass production.

One can safely assume that the main weight difference between the Zero and the Hayabusa was that the latter did not need the sort of structural strength a plane requires to land on an aircraft carrier.  One drawback of this was that the Zero, which was never what one would call a sturdy aircraft, was by comparison to the Hayabusa carved out of a single block of iron.  Another way the Hayabusa saved weight was in the form of weaponry.  For most of the war, the Ki-43 carried only a pair of 7.7mm machine guns, the exact same armament as a Sopwith Camel from World War I.

At the beginning of the Pacific War though, this was enough.  In combat, the Hayabusa was nearly as successful as the Zero.  Being able to outturn and outclimb anything in the skies, once an Oscar got on a plane's tail, it could pretty much stay there at will.  It was only a tiny bit slower than a Zero as well.  All of this meant that it was a dangerous package.  It even had some armor for the pilot and rudimentary self-sealing fuel tanks to boot. 

The Hayabusa's main weakness was that it was ridiculously fragile.  While less prone to catching fire like the Zero, it tended to come apart under Allied gunfire.  Indeed, hits that even a Zero could shrug off were often enough to cause the Ki-43 to shatter like porcelain.  The hard part was landing a blow on the nimble little plane in the first place. 

Upgrades were applied to the Ki-43 over the course of the war.  First, a larger engine was installed that gave better performance at high altitudes, then the guns were upgraded to 12.7mm.  However, these upgrades were never going to be enough to keep up with newer Allied planes like the Hellcat, Corsair or Seafire.  Replaced by the Ki-44 (Tojo) and Ki-61 (Tony), it was never entirely phased out and stayed in front-line service for the entire war.  As with most other Japanese planes, it ended the war in a Kamikaze role, but not until nearly 6000 were built, making it the second-most popular Japanese fighter... behind only the Zero.  Every IJA ace got the majority of his kills in the Oscar, and one source in my collection even claims that the Ki-43 was responsible for shooting down more Allied planes than the Zero.  Not a bad record for a fragile, slow, undergunned fighter that was overshadowed by the A6M.

Today, only six Ki-43s are known to exist, and only one of those is in flyable condition.

The Curious Class

The year is 1904 and James Arbuthnot Fisher had reached the absolute pinnacle of his career.  After fifty years in his chosen profession, he was arguably the most powerful man in the world.  You see, James Arbuthnot Fisher was better known as "Admiral of the Fleet Sir Jackie Fisher, First Sea Lord."  As such, he was the commander of the British Royal Navy, the strongest military force under the sun, answerable only to His Royal Highness, King Edward VII. 

In the past, Admiral Fisher had shown two interesting traits: an innovative mind, and a love for anything fast.  Some 10 years earlier, he had essentially created the class of ship we now know as the destroyer.  Now he had the power to push through his greatest idea yet: a battleship armed with nothing but one size of large-caliber guns.  She was to be named HMS Dreadnought, and her very existence made the rest of the world's battleships obsolete at a single stroke.  Obviously well-armed, well-armored, and (of course) fast for her time, the Dreadnought was a marvel. 

And then he had to go and create a companion for the Dreadnought design.  The concept was a good one: a ship able to chase down and kill commerce raiders in independent action, and able to act as the eyes of the battleline in a fleet action.  It was to be able to outfight anything it could outrun, and outrun anything it couldn't outfight.  To do this required two things: high speed, and high firepower... a tall order, even for today's technology.

For the early 1900s, there was only one solution... take away weight.  In essence, what Admiral Fisher wanted was to build a Dreadnought-class ship, but without all that pesky armor.  And, being First Sea Lord of His Majesty's Royal Navy, what Admiral Fisher wanted, Admiral Fisher got.  What he got was the HMS Invincible, the world's first battlecruiser.

Weighing the same as the Dreadnought within a couple hundred tons, the Invincible carried eight 12" rifles in four twin turrets.  While this was two guns fewer than the Dreadnought,  better positioning of the two wing turrets allowed them to fire to their opposite side.  As a result, she could fire the same strength broadside as the bigger ship, which had only six guns on the center, and two wing turrets that could only fire to their respective sides.  The Invincible had 31 boilers driving four turbine-powered shafts, generating anywhere from 41000 to 46000 shaft horsepower, nearly twice the shp of the Dreadnought.  As a result, the Invincible could make 25kts, and nearly reached 27kts during builder's trials.  Her larger cousin could only make 21kts.  But all that speed came at a dramatic cost.

Misunderstanding Midway

Down in the comments section of the post "The Reason for Midway", there's a sight to warm the heart of any blogger: an energetic argument discussion.  Longtime readers CXT and Avatar are doing a fine job of carrying the flag of disagreement with Bob, I wanted to pay closer attention to something he said at the very beginning of his comments.  To whit:

"These discussions are interesting but so narrow as to be misleading.  The entire Midway exercise didn't matter, regardless of outcome."

It will come as no surprise to readers of The Pond that I vehemently disagree with this statement.  To be honest, in one way I do agree with Bob in that Japan had no chance of winning an overall military victory against the forces of the United States, Britain, Australia and the Dutch.  However, that does not mean that Midway didn't matter, any more than it means that Guadalcanal/the Solomon Islands, Leyte Gulf, Iwo Jima, Tarawa, or even Attu and Kiska, didn't matter.

Once the first A6M2s, D3A1s and B5N2s lifted off from the Akagi, Kaga, Hiryu, Soryu, Shokaku and Zuikaku on their way to Pearl Harbor on December 7th, 1941, sterile discussions over such concepts that Bob mooted became academic: win or lose, the die was cast and everything mattered.  Only in hindsight can we say "it was pointless and the Pacific War shouldn't have been started".  The fact of the matter is that it did start, men did fight, and it did matter... every bullet fired, every torpedo launched, every bomb dropped, every grenade thrown, mattered.

It mattered to 3400 men at Midway.  29000 men at Iwo Jima.  38000 men at Guadalcanal.  7000 men in the Aleutians.  12000 at Peleliu.  And hundreds of thousands more at dozens of other locations across the Pacific.

To suggest that these battles "didn't matter", no matter how large the stack of scholarship one may bring to the table, is ridiculous and insulting to those who participated and survived, those who were there and were injured, and to those who fought and died on both sides.  Don't take my word for it, however... walk up to a Pacific War veteran and tell him his actions didn't matter.  Just let me know where and when you intend to do it, so I can bring popcorn.

Regarding the first part of Bob's statement, it seems clear that he doesn't read The Pond overmuch.  Very nearly by definition, I blog about "the narrow", because that's where my interests lie.  Sure, I could write about the geopolitical situation surrounding the beginning of WWII in the Pacific, but I'd hate every moment of it.  I'm an amateur historian of the military actions of the Pacific War, with an emphasis on naval battles, and a particular emphasis on the Battle of Midway, because that's what I like... and I write about what I like.  I won't apologize for being "too narrow" for someone's taste.

Particularly when it "doesn't matter".

Missing Midway Photography

Unless you're like me, and heaven help you if you are, you may not have noticed one of the most surprising facts surrounding the Battle of Midway.  That is, where are all the pictures of the Japanese carriers?   Now, I can hear you saying "Wonderduck, there's plenty of pictures of Kido Butai at Midway out there!  Just look at this one of the Akagi!"

"Or this one of the Soryu!"

"Or this one, it's the Hiryu!"

"Or this one, of the Kaga... er... hey!"

I'm sure there are variants of the above three pictures in the National Archives, but for all intents and purposes, those are the only images of the Japanese carriers involved at the Battle of Midway that we have.  Taken from B-17s on the morning of June 4th, 1942, they represent the entirety of the US photographic effort during the battle.

Or do they?

The Reason For Midway

Reader Siergen asks: "Assuming that the Japanese had succeeded in taking Midway, did they have any plans to actually use it, such as for land-based bombing of Pearl harbor?  Or was it intended solely as bait to lure the US carriers out and sink them?"

A fine question.  Indeed, there was a strategic reason for the Japanese to take Midway.  However, in my estimation, their reasoning was somewhat... flawed.  As the War in the Pacific drew close, the Japanese military knew that they could not realistically go toe-to-toe with the United States for more than a year or so, two years maximum (let that sink in: they started a war they could not win militarily... and knew it).  Instead, they intended to win politically, by inflicting such heavy losses on the US and her allies that they'd give up and go for a political settlement.  In the political realm, they believed that they'd have a strong case for keeping their conquests (primarily the Indonesia area, with her rubber, tin and oil deposits) and become both self-sufficient and the unquestioned master of Asia.

To do this, the Japanese adopted a strategy that relied on the concept of a defensive perimeter.  They figured that if they captured enough island bases, like Wake, Guam, Rabaul, and the Philippines, then improved them to stronghold status so they'd be impossible to re-take, they'd be able to create an impassible border that would keep the Japanese Home Islands secure.  Along the way, they'd also attempt to sever the lines of communication between Australia and the US, though that would be more of a bonus than a goal.  It's hard to imagine the strategy without looking at a map, so let's use a simplified one: the board for the game Victory In The Pacific, by Avalon Hill.

This would be the situation going into June, 1942.  The shaded zones are controlled by the Japanese, the lighter areas by the US and her allies.  The defensive perimeter is starkly evident this way, along with the one weak area in the strategy: there are two open paths directly to the Home Islands.  The first is from the "Hawaiian Islands" area directly through the "Central Pacific"; the other, through the "North Pacific" and "Aleutian Island" zones. 

Prior to the Doolittle Raid, there was quite a bit of debate in the Japanese military command as to what the next targets would be... in effect, they had been so successful so quickly, they outstripped their own plans.  But then the attack using B-25 medium bombers, flying from the deck of the USS Hornet, made clear that the Home Islands were still vulnerable, and the plans to attack Midway and the Aleutians were approved.  Capturing those "areas" would prevent any attacks to slip through without being discovered and countered, either via ships sailing from Truk or from Japan proper

There was never any plan to use Midway as a point to launch aerial attacks on Pearl Harbor; even for the incredibly long-legged Japanese aircraft, the 1300 mile flight was too far a distance.  Instead, it would be a self-defending base able to send reconnaissance flights out to patrol the waters around it.  Just how the Japanese would be able to keep Midway supplied was never really answered; they would figure it out when the time came.

The flaw in this strategy is that the real world isn't a game board with zones of control that prevented enemy movement, yet in effect that's exactly how the Japanese were looking at it.  The Pacific Ocean is huge, particularly in the Northern and Central Pacific areas, with vast stretches of open sea where ships could sail without ever being noticed.  Indeed, the fleet used in the attack on Pearl Harbor took advantage of this fact on its approach.

The attack on Midway had the goal of sinking the American aircraft carriers, no mistake about it... but defending the Home Islands was the primary goal.  That the strategy behind the goal probably wouldn't have worked was apparently never considered.

The Brewster Buffalo: Midway's Most Reviled Plane

When one thinks of the Battle of Midway, images of Dauntless dive-bombers plummeting down towards Japanese carriers immediately leap to mind.  Or perhaps the tragic story of the massacre of the three torpedo squadrons flying TBD Devastators is the more dramatic, and therefore more memorable, saga.  Whatever the military buffs out there think of, it's unlikely that the Brewster F2A Buffalo would get more than a derisive snort, if even that.

That's somewhat unfair to what was the US Navy's first monoplane fighter.  As originally designed, the Buffalo was actually quite nimble and well-liked by its pilots.  Indeed, its wing-loading was only slightly higher than that of the Zero.  No less a name than Marine pilot Pappy Boyington praised the Buffalo, saying "they were pretty sweet little ships. Not real fast, but the little plane could turn and roll in a phone booth."  The most glaring weakness of the F2A was its armament: two machineguns in the nose, one .50cal and one .30cal, a most odd combination.  The landing gear was considered marginal for use on carriers, but good enough.

But then the Navy accepted it for service... with a few modifications.  Armor plate was added, as was a larger-capacity self-sealing fuel bladder.  Further, two wing-mounted .50cal guns were also added... all of this on just a 900hp engine.  Performance in the form of top speed and climb suffered badly in a plane not great in either category.  By 1941, the Buffalo had turned into the F2A-3, with a 1200hp engine (the benefit of which was mostly lost by the increased weight it added, both in its size and in the larger airframe required to mount it), even more armor, and a bigger wing with integral fuel tanks.  This increased the range to nearly 1000 miles, giving it much longer legs than the F4F Wildcat, but ruined the plane's one true feature, its handling.

By the Battle of Midway, the Buffalo had become too slow, too heavy and too lethargic, a bad combination for a fighter plane.  However, as someone many years later said, "you don't fight wars with the military you want, you fight wars with the military you have," and when the Japanese planes were approaching Midway Atoll, what the defenders had were the 21 Buffalos and seven F4Fs of Marine Fighting Squadron 221.

The result was both better and worse than anybody could have expected.  Despite being outnumbered by the 36 Zeros escorting 72 bombers, 17 Japanese planes were shot down by VMF-221, but at the cost of 13 Buffalos and 2 Wildcats (and all of their pilots) lost.  Of the remaining planes, only two were still airworthy after the fight.  F2A pilots were vociferous in their condemnation of their planes afterwards, one going so far as to state "(the)F2A-3 is not a combat airplane... ...it is my belief that any commander that orders pilots out for combat in a F2A-3 should consider the pilot as lost before leaving the ground."

After the Battle of Midway, all remaining Navy Buffalos were sent to the US mainland as advanced training aircraft, which duty it performed until 1944.  Because of the infamous quality that Brewster built their planes with (i.e., none at all), there are only three F2As known to survive.

Outside of the US Navy, however, opinion of the Buffalo is much higher.  The British, Australian, Dutch and Finns all used an export variant of the plane.  The Finnish Air Force in particular used the B-239E variant to great effect in the air war against the Soviet Union, with one squadron (Lentolaivue 24) registering 459 kills, while losing 15 B-239s.  It's notable that these variants did not have the extensive armor plating and heavy self-sealing fuel tanks of the F2A, and therefore kept its maneuverability.  To be fair, however, the Finns were not fighting against Zeros flown by crack pilots, but poor Soviet pilots with lousy leadership and, at least at first, obsolete planes. 

In conclusion, the F2A deserves more respect that it is shown.  It was an acceptable enough fighter to begin with, but by the time the Navy was finished throwing stuff into it, it had become a pig.  Consider it a lesson learned, similar to the one the US Army learned with the P-39 Airacobra.  That it was outclassed by the Zero isn't a mark of shame; everything was outclassed by the A6M2 in 1942.  Without the Buffalo being present at Midway, the Japanese might have done more damage to the base there.  Enough to render it unusable?  Probably not, but with the F2A present, they certainly didn't. 

It wasn't a great plane, but it was there.

Beginning The Miracle

As all good Pacific War otaku know, the 69th anniversary of the Battle of Midway is coming up early next month.  Regarded as the most stunning and important victory in the history of Naval warfare, three US aircraft carriers, supported by aircraft flying from Midway Atoll, attacked and sunk four Japanese aircraft carriers, three of them in the space of just a handful of minutes on June 4th, 1942.

While the US was outnumbered by the Japanese in the number of aircraft carriers present at the battle, the Americans had broken the Japanese radio codes and had a detailed knowledge of their plans for the whole skirmish.  Taking advantage of this, the US Navy in effect ambushed the Japanese fleet.  Of course, the victory did not come without cost.  Three squadrons of torpedo planes were effectively wiped out, and one of the American carriers, the USS Yorktown, was sunk.

The Japanese presumed the Yorktown to have been sunk a month earlier, at the Battle of the Coral Sea.  Indeed, she had been beaten up, but the first and possibly greatest of the "miracles" of Midway had occurred in the intervening time.

Or had it?

The Pacific Q-Ship

In 1915, things were looking grim for the British Isles.  Unrestricted submarine warfare was slowly strangling the country, cutting off the flow of supplies to the nation.  Stocks of fuel, armaments, supplies and food were all at desperately low levels... the Allies were losing the Battle of the Atlantic.  At that time, defenses against submarines were rudimentary at best.  Sonar was non-existent, depth charges were crude and for the most part ineffective, and the homing torpedo wasn't even thought of yet.  The only realistic chance that a defending ship had to sink a submarine was to catch it on the surface.

While it's hard to imagine a submarine allowing itself to be caught on the surface these days, things were different in 1915.  At the time, submarines were what would be called "submersibles" today: able to descend under the waves for a short time only, while doing most of their movement on the surface.  Because their underwater time was limited, a sub would "go under" only when preparing for an attack run... and not always then.  The torpedoes of the time were cranky, ill-tempered beasts that were often unreliable, and always in short supply.  It was quite common for a submarine to sneak up on a target, surface, then engage with a deck gun.  Of course this would only work against an unarmed freighter or transport; it goes without saying that an actual warship would receive a torpedo fired from underwater.

However, even this limited method of attack was extremely effective against unarmed merchant craft... so effective that England was on the verge of starving.  The obvious defense, convoying, or putting a large number of merchant vessels in one group while defending them with one or more warships, was ruled out by the ship-strapped Royal Navy.  There just weren't enough warships to go around.  Something had to be done, and quickly.  Two innovations arose from this desperate need.

The first was the armed merchantman.  More of a throwback than a true innovation, at its heart the armed merchantman was a descendant of the age of sail, when almost every East Indiaman had a good number of cannon lining its rails to fight off pirates and privateers.  The generic armed merchantman of WWI-vintage would have the firepower of a destroyer or light cruiser, six 6" guns and various numbers of smaller guns as a secondary battery.  Since they were built as merchant vessels, they were however fragile: little in the way of compartmentalization to prevent flooding, little if any armor (other than raw size) to prevent damage, with a slow top speed that prevented running away.  Armed merchantmen were mostly for use against commerce raiders as a self-defense measure: if a warship came upon an armed merchantman, at least there was some way to fight back.  However, with their guns carried on deck, they were just as likely as a battleship to attract a torpedo from a submarine.

The second innovation was the Q-ship.  Take a freighter and turn it into an armed merchantman... then hide the guns inside false panels or deck structures or belowdeck.  When a submarine approached, it'd see a nice big fat undefended target, surface and engage with the deck gun... at which point, the Q-boat would drop the false panels, run out the guns and with the element of surprise blow the submarine out of the water.  To be sure, they could take on a surface vessel as well, but their weapons were more designed to engage fragile submarines: a hole or two would prevent a sub from diving, trapping it on the surface.  Q-ships had no set armament loadout, but multiple 3" guns were common.

Despite the clever idea, Q-ships were generally ineffective against submarines in WWI, accounting for less than 10% of all kills scored.  Instead, they were more of a psychological weapon, preying upon the mind of a U-boat captain.  If any freighter could be heavily armed and just waiting for you to surface, the sub captain might be more reluctant to do so, and either let the freighter go or waste a precious torpedo on it.

During WWII, there was a repeat of the WWI Battle of the Atlantic, and the Q-ship concept was revived.  It was even less successful than in WWI, mainly because advances in submarine technology meant that a sub could spend less time on the surface, torpedoes were much less prone to failure and in greater supply.   The Royal Navy commissioned nine Q-ships in 1939, two of which were sunk on their first mission.  None of them sank a U-boat, and they were quietly retired in 1941.  The US Navy converted five cargo vessels to Q-ships, one of which was sunk and the other four failed to engage a submarine during their two-year run.

And then there was the USS Anacapa.

Iowa's Bathtub


The USS Iowa was the namesake for what was arguably the best class of battleships ever built.  Launched in 1942, she was commissioned in 1943.  Displacing 45000 tons, her engine rooms could still move her through the water at a blistering 33kts.  Her main armor belt was 12" thick, while her three main turrets were armored to nearly 20" in thickness.  Those turrets carried three 16"/50cal rifles each, and each of those guns could fire a 2700lb shell over 23 miles.  Twenty 5"/38cal guns formed her secondary battery, and could be used for both anti-aircraft or anti-surface work.  Four of the mammoth warships were built.

But only one had a bathtub.

Late in 1943, the heads of state for the three major Allied countries, Joseph Stalin, Winston Churchill and Franklin D Roosevelt, were to meet in Tehran for a strategy conference.  The US Navy choose the USS Iowa to take President Roosevelt on the first leg of the journey to Iran, crossing the Atlantic Ocean.  But there was a small snag.  President Roosevelt had developed an illness in 1921, at the time diagnosed as polio, that had paralyzed him from the waist down.  He could only walk by swinging his legs laboriously via a twist of his torso, and leg braces and crutches were mandatory.  FDR was also pretty much incapable of standing without assistance from one or two individuals.  This ruled out his use of a shower, at the time the only form of bathing available on US warships.  As the trip would take quite some time, something had to be installed for his use.  That something was Iowa's Bathtub.

Who knew?

Midway Tragedy

Roughly halfway between the west coast of America and Japan, there lays a small atoll consisting of two significant islands and a handful of smaller ones, mostly surrounded by a low-lying reef.  Called "Midway" for obvious reasons, it was first a location for guano mining.  Later, Pan Am used the atoll as a stopover point for their "China Clipper" service.  As World War II approached, the US military recognized it as having an important location for the defense of the west coast.  Barracks, runways, gun emplacements, a seaplane base, and even a submarine base appeared, seemingly overnight.

Of course, we remember Midway as the namesake location of one of the most important battles of any sort in history.  One aspect of Midway atoll that seemingly every history of the Battle remarks upon are the ubiquitous avian residents, the Laysan Albatross.

Better known as the Gooney Bird for their goofy, clumsy appearance on land, nearly a million of these birds live on Midway today, and there's no reason to think any fewer were there during WWII.  Gooneys are known to have extremely long lives, with the oldest known to be over 60 years old, and possibly older.  It's quite possible that some Gooneys alive today were present on Midway during the battle.

Lost among the tragic news reports coming out of Japan in the wake of the magnitude 9.0 earthquake and huge tsunami that followed it, were bulletins from Midway atoll.  Sand Island, the largest of the islands that make up Midway, was 20% covered by water from the tsunami's five foot tall waves, while Eastern Island had been 60% covered.  Spit Islet, the largest of the minor land masses that make up the atoll, was completely inundated.  As a result of this, over a thousand adult Gooney birds were killed, and many thousands of flightless chicks were drowned as well.  "We may see just a slight decline in breeding birds next year, next year and the year after that," said Barry Stieglitz, project leader for the Hawaiian and Pacific Islands National Wildlife Refuges. "There will be a gap in the breeding population when these birds that would have grown up this year, would have matured and started breeding for the first time."

Genesis Of An Aircraft Carrier

In 1905, the Imperial Japanese Navy (IJN) showed the world that is was at least the equal of any Western navy by its complete domination at the Battle of Tsushima.  In this climax to the Russo-Japanese War, the Japanese battle fleet, commanded by Admiral Togo, annihilated the Russian Second Pacific Squadron at the cost of three small torpedo boats.

By 1906 though, the Japanese fleet was made obsolete by the appearance of HMS Dreadnought in the British Royal Navy.  Realizing that evolving technology had laid their fleet to waste (and terrified by that fact), the IJN made plans for a new and improved fleet of ships.  Called the "Eight-Eight Fleet", it was to be based around eight new Dreadnought-style battleships and eight cruisers.  Designed to be capable of going toe-to-toe with the US Navy, even at this early date thought to be Japan's most likely foe, this battleline was considered the only way the nation of Japan could be made safe.  Though the country had been practically bankrupted by its war with the Russians, the first batch of ships was approved in 1911.

Events on the other side of the world again worked against the IJN's plans.  While Japan had sided with the Allies in World War I, for all intents and purposes she had little to do with the European theater of war.  Instead, she had little spats with far-flung German possessions in the Pacific.  Meanwhile, the war in the Atlantic led to massive improvements in naval technologies for the combatants there.  Suddenly, the IJN again found themselves with seemingly obsolescent ships while their rivals had honed their fleets against the whetstone of war.

The decision was made to scrap the first Eight-Eight fleet plans and start a second.  This second fleet was to be built around a nucleus of the newest vessels of the first, two completed battleships of the Nagato-class, two Tosa-class battleships that were in the process of being built, and four Amagi-class battlecruisers that were in various stages of construction.  They were to be joined by four battleships of an unnamed class that was to carry 18" guns, and four "fast battleships" to accompany the battlecruisers.

The Amagi-class was to tip the scales at over 41000 tons, be capable of 30kts, and carry ten 16" guns on a hull some 826 feet long.  As with all battlecruisers, the Amagis were not particularly well-armored; they were designed to be able to outgun anything they could outrun (cruisers of all sizes and destroyers), and outrun anything that outgunned them (battleships, mostly).  While in retrospect it's clear that the battlecruiser concept was deeply flawed, the thinking of the time was that speed, not armor plating, would be a battlecruiser's best defense. 

Tosa-class battleship
The Amagi's heavier teammate on the battleline, the Tosa-class battleship, was paradoxically smaller than the battlecruiser in most ways.  Coming in at just under 40000 tons and 760 feet long, they were to cruise at just over 26 knots.  Armed with ten 16" rifles of the same type carried by the battlecruisers, their secondary battery of twenty 5" guns compared favorably to that carried by the Amagi.  As with most battleships, the Tosa's armor was to be its strong point.  In short, the Tosas were to slug it out with opponents while the Amagis danced in and out of the battle.

In 1922, the IJN's plans again had to be scrapped when Japan became a signatory to the Washington Naval Treaty.  This attempt to curtail the growing naval arms race ongoing between Britain, America, Japan, France and Italy placed an upper limit on the size of any ship built of 35000 tons.  All work on the four battlecruisers and two battleships came to a halt, in preparation for scrapping.  With the stroke of a pen, both the Amagi-class and the Tosa-class, like the British N3 and G3 designs, had been invalidated. 

Or almost so.  The Treaty placed an upper limit on the size of aircraft carriers of 27000 tons.  However, a provision of the treaty, insisted upon by both the Americans and the Japanese, allowed for the conversion of two ships of a maximum weight of 33000 tons each to aircraft carriers.  The US Navy selected two Lexington-class battlecruisers for conversion. The IJN chose two of their Amagis, the namesake of the class and the Akagi, to be subjects for their conversions.  The remaining battlecruisers were broken up and scrapped.

And then nature stepped in.

The Littlest Aircraft Carriers

In the 100 years that navies have taken airplanes to sea, there have been some truly creative methods employed to get an organic aircraft capability onto ships.  Barges towed behind destroyers.  Launching platforms on the turrets of battleships.  Explosive catapults on the bows of merchant ships.  Submarines with floatplanes.  Merchantmen with a rudimentary flight deck laid over their cargo areas.  The list could go on forever, but none of them were really a success.

During the Allied invasion of Sicily, there was a need for artillery spotting airplanes.  The usual plane used, the L-4 Grasshopper (better known in civilian use as the famous Piper Cub), didn't have the range to actually fly to Sicily from Allied bases, and aircraft carriers decks were too valuable to ferry them there.  Having them transported in a knocked-down state was possible, but it was time-consuming to have to put them back together.  Knowing all this, a US Army pilot named Captain Brenton Devol, suggested a solution: put a flight deck on a LST.  And lo, was the tiniest aircraft carrier created.

LST-386 was fitted with a flight deck made of timber and pierced metal runway mats.  It measured 216 feet long by 12 feet wide, and it took just over 36 hours to build.  It could carry four Grasshoppers, plus its normal load of cargo and troops in her tank deck. 

Sign #14 that pilots are insane.
The conversion was so successful that five or six other LSTs were fitted with their own flight decks.  As time went on, the design was refined to allow nine Grasshoppers to be carried.  Four of them, shown above, were carried on minuscule ramps, while the other five were on a platform just ahead of the bridge.  The LST would go as fast as she could into the wind, usually winding up with a 20kt breeze to aid the L-4s into the air.  The lightweight plane would fairly skip into the sky with that amount of help.  Accidents were not unheard of, but all in all the LSTCV was a successful and useful design.

However, these LST conversions could not be considered true aircraft carriers.  There was no provision for recovering the L-4s after launch; the planes would have to land behind friendly lines after takeoff.  Considering the short-field capabilities of the Piper Cub, one could imagine a scenario where the LST would steam backwards while a white-knuckled pilot tried to land on the narrow pitching deck.  It could work, but it seems unlikely.

But out in the Pacific theatre, something different was invented... something that was allowed a LST to become a true aircraft carrier.  This something was called the Brodie Device.

CV-1

In 1918, the Royal Navy commissioned the world's first ship to be easily recognizable as an aircraft carrier, the HMS Argus.  In 1922, the Imperial Japanese Navy commissioned the first ever ship designed and built as an aircraft carrier, the Hosho.  In between, the US Navy sent to sea the first of an unbroken line of carriers that led directly to today's nuclear-powered supercarriers. 

But on the face of it, the American carrier had a very odd beginning.

The USS Jupiter (AC-3) joined the fleet in 1913 as the first electric-drive ship in the US Navy.  A collier, her job was to provide underway replenishment to the fleet.  This task led to her most distinctive feature, the vertical towers, called kingposts, amidships.  These were structural supports for coaling booms, which would be lowered when a ship was alongside.  Coal would then be sent down the booms to the decks of the receiving vessel.

These kingposts proved to be one of the reasons she was selected to become the basis for the first US aircraft carrier.

The Seaplane Tender That Changed The World

After that headline, you're probably rolling your eyes... what seaplane tender changed the world?

That one... and I'm working on a ship profile on it.  I intended to have it up tonight, but it's not happening.  It will be up sometime Monday, as I've got the day off, so look forward to it!

(ps - no, this isn't a "name that ship" contest, I just wanted to put a teaser picture up, though if you want to take a shot, go ahead)

The Forgotten Hero Ship

In my own personal shorthand, there is a category I call 'hero ships.'  These vessels, for one reason or another, just stick in the mind as incredibly important... even if they really weren't in the grand scheme of things.  Sometimes it's just because they have a cool name, sometimes it's because they seemed to be in the midst of all the action, sometimes it's because they were particularly influential.  Ships like USS Enterprise, or HMS Ark Royal (the greatest name for a ship ever).  The IJN Yamato is a 'hero ship,' even though it didn't do much in WWII.  So are the Bismarck and the HMS Hood, fated to be forever joined on history.  The doomed USS Indianapolis and USS Arizona.  There are probably dozens of others in my head, ships that anybody with any knowledge of WWII have heard of.

Then there's the ship we're discussing here.  Imagine if you will a vessel that was present at the following battles: the Doolittle raid; Midway; the attacks against the Solomons; Guadalcanal; New Georgia; Wake Island; the Gilbert Islands; the Marshall Islands; Truk; the Marianas battles; Luzon; the naval raids on the Japanese home islands; Iwo Jima; Okinawa; Tokyo Bay.  She also just missed the Coral Sea.

And yet, nobody considers her a 'hero ship'... and they really should.  For without her and her sisters, the US would have had a much harder time of it in the Pacific War.

The Misfit Battleships

When one thinks of battleships, what leaps to mind?  The gleaming Iowas, usually.  Others would think of the hulking Yamato-class, still the largest battlewagons ever built.  Or perhaps the menacing Bismarck and Tirpitz, pride of the Kriegsmarine would hold primacy over all.  If you have a sense of history, classes like the Nevada/Pennsylvania, with their cage masts and one of which, the Arizona, is now one of the US military's most hallowed sites.  Or the first of them all, the Dreadnought.

And then there's me.  I'm a weirdo, because my favorite battleship class is one that few people know or (historically) care about.  You see, I'm a fan of the Nelsons. 

I can hear you now: "The whichnow?"  These:

The sharper-eyed amongst you have already noticed the obvious difference.
