WWII Toys of a Different Kind

The Battle of the Coral Sea fought from 4–8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces from the United States and Australia, taking place in the Pacific Theater of World War II. The battle is historically significant as the first action in which aircraft carriers engaged each other, as well as the first in which neither side’s ships sighted or fired directly upon the other.

In an attempt to strengthen its defensive position in the South Pacific, Japan decided to invade and occupy Port Moresby (in New Guinea) and Tulagi (in the southeastern Solomon Islands). The plan to accomplish this was called Operation MO, and involved several major units of Japan’s Combined Fleet. These included two fleet carriers and a light carrier to provide air cover for the invasion forces. It was under the overall command of Japanese Admiral Shigeyoshi Inoue.

The U.S. learned of the Japanese plan through signals intelligence, and sent two United States Navy carrier task forces and a joint Australian-American cruiser force to oppose the offensive. These were under the overall command of American Admiral Frank J. Fletcher.

On 3–4 May, Japanese forces successfully invaded and occupied Tulagi, although several of their supporting warships were sunk or damaged in surprise attacks by aircraft from the U.S. fleet carrier Yorktown. Now aware of the presence of U.S. carriers in the area, the Japanese fleet carriers advanced towards the Coral Sea with the intention of locating and destroying the Allied naval forces. Beginning on 7 May, the carrier forces from the two sides engaged in airstrikes over two consecutive days. On the first day, the U.S. sank the Japanese light carrier Shōhō; meanwhile, the Japanese sank a U.S. destroyer and heavily damaged a fleet oiler (which was later scuttled). The next day, the Japanese fleet carrier Shōkaku was heavily damaged, the U.S. fleet carrier Lexington critically damaged (and later scuttled), and Yorktown damaged. With both sides having suffered heavy losses in aircraft and carriers damaged or sunk, the two forces disengaged and retired from the battle area. Because of the loss of carrier air cover, Inoue recalled the Port Moresby invasion fleet, intending to try again later.

Although a tactical victory for the Japanese in terms of ships sunk, the battle would prove to be a strategic victory for the Allies for several reasons. The battle marked the first time since the start of the war that a major Japanese advance had been checked by the Allies. More importantly, the Japanese fleet carriers Shōkaku and Zuikaku – the former damaged and the latter with a depleted aircraft complement – were unable to participate in the Battle of Midway (the following month) while Yorktown did participate, ensuring a rough parity in aircraft between the two adversaries and contributing significantly to the U.S. victory in that battle. The severe losses in carriers at Midway prevented the Japanese from reattempting to invade Port Moresby from the ocean and helped prompt their ill-fated land offensive over the Kokoda trail. Two months later, the Allies took advantage of Japan’s resulting strategic vulnerability in the South Pacific and launched the Guadalcanal Campaign; this, along with the New Guinea Campaign, eventually broke Japanese defenses in the South Pacific and was a significant contributing factor to Japan’s ultimate defeat in World War II.

In the terms of the Pacific War, how did this battle change the shape of the campaign before the battle of Midway?
How do you guys think Midway would have went if the Japanese carriers Shokaku and Zuikaku were present at the battle alongside the other carriers?
Neither side saw each other during this battle and yet it happened.
Pretty much declared a draw, what do you guys think?

Well, the battle takes place during daytime, the most favourable conditions. I read the article in my research, and the battle really was tough to decide. Many people point to Leyte Gulf as proof of how bad Japanese battleships are. But one of the reasons for the Japanese failure off Samar was because of the Japanese using armour piercing shells, which often flew right through the unarmored American ships without exploding. Mistakes in commanding the Japanese ships was another reason for why the American fleet was not destroyed. As I said, it was really hard to decide, and it was very close. As you noted though, the Japanese has inferior radar and sighting, the Japanese had superior armour and had just so many guns that it would have eventually have hit several times, especially if the Missouri went to point blank range, like how I thought the battle would have worked out. It honestly could have gone either way.

@221B:

While they probably would never fight it out directly against each other, I think that the submarines of that era could be compared to each other in terms of how well they did (and how well they potentially could have) against merchant marine ships.

I’d have to place them in this order with regards to their potential:

Japan Germany US UK Italy

Of course, the Japanese squandered the potential of their subs by using them to attack warships, rather than merchant ships.  So in order of actual performance, I’d say this order:

US (Japan was devastated by lack of supplies) Germany UK Italy Japan.

Part of the reason for my placing Germany below the US is because the allies, particularly the British developed effective defenses which the Japanese did not (and the Germans did not need to as they were a continental power).  Not sure where to place Russia, but since (like Germany) she is a continental power, there was very little, if any, efforts regarding submarines that I am aware of.

I’d also like to point out that Germany had some very interesting submarine ideas on their drawing boards, but either chose not to (or were unable to) develop these in any meaningful fashion.

Thoughts?

Good post, and I agree with what you’ve written. I’d like to expand on what you’d written about Germany’s very interesting sub ideas. Late in the war, Germany had begun building highly advanced Type XXI U-boats. These were built in sections, to allow for a faster rate of production. These submarines had more in common with postwar nuclear subs than with their WWII contemporaries.

Most WWII-era submarines were intended to spend most of their time above water, surfacing only when threats were detected or battle expected. Type XXI U-boats were intended to spend nearly all their time underwater. The batteries of Type XXIs lasted several times longer than normal subs’ batteries before being recharged. These subs had a snorkel–a snorkel which allowed them to run their diesel engines and recharge their batteries while still submerged!

Type XXI subs had a rubber coating, making them far more difficult to detect with radar or sonar. Even if a sub was detected, it could use its battery-powered electric motor to quietly move to some other place. These subs could also move quickly! Unlike other WWII-era subs, Type XXI subs moved more quickly under the surface than they did on the surface. This was because of their hydrodynamically advanced, streamlined design. These subs also had very sophisticated electronics suites, perfectly suited to an underwater game of cat and mouse. These U-boats could fire large numbers of torpedoes in a small space of time; allowing them to strike a devastating blow and then disappear.

Most torpedoes of the era were diesel powered. Compressed air was mixed with diesel fuel and burned, thereby turning the torpedo’s propeller. The compressed air used in this left a trail of bubbles–a trail which both alerted people to the torpedo’s arrival, and provided a path back to the launching submarine. In some places, that bubble trail would glow at night due to phosphorescent microorganisms. Japan’s torpedoes used compressed oxygen with which to burn diesel. That meant a much smaller bubble trail, and significantly longer-ranged torpedoes. (The Allies’ bubble trails consisted mostly of nitrogen gas, which of course is useless for burning anything.)

Germany used electric torpedoes. These had the advantage of being much quieter and more difficult to detect than diesel-powered torpedoes. And of course they left no bubble trail. The problem with Germany’s early electric torpedoes was that the batteries weren’t that good, causing the range to be too short. But batteries improved throughout the war, thereby extending the torpedoes’ range. While Germany’s electric torpedoes never came close to the range of Japan’s Long Lance torpedoes, they nevertheless had a very respectable range by the war’s end. When that range was combined with the overall stealth and sophistication of Germany’s Type XXI U-boats, the effect was absolutely devastating.

Or would have been, had those Type XXIs seen service. In 1944, Albert Speer ordered the construction of large numbers of Type XXI U-boats. Some of those Type XXIs were in the testing/working up phase when the war ended. None saw action against the enemy. A smaller version–Type XXIII U-boats–appear to have been very effective in limited action against the enemy. However, Type XXIII U-boats could only carry two torpedoes each, and were limited to coastal duties.

I bet, many of you are like me, I grew up reading the Bantam WWII series of books. I starting looking at the number of books produced and realized how many i have not read.

What is your favorite? I love Iron Coffins, Samurai & Company Commander.

The recent Lybian Civil War has been one of the more interresting post WWII conflicts.

of course i forgot about Ray Spruance…the true hero of Midway and one of the best Admirals of the war

Rommel praised the fighting ability Australian troops in North Africa, he considered 9th Australian the best division in Africa.

I played WaW once. Didn’t like it much. But I’ll give it another try if you think it is worth it.
