Flattops and Flyboys: The Carrier War in the Pacific 1942-44

A new kind of war
In the Great War, the Royal Navy invented the aircraft carrier, the first ships to be modified to launch and recover combat aircraft. Although they did not accomplish much during the war, the promise was clearly there. Soon after the war the Japanese and American navies followed the British in building more of these ships, including by the 1930s carriers designed and built to field powerful air striking forces of torpedo and dive bombing squadrons, as well as fighters to defend the fleet.

HMS Furious (1918)


When the war began, the British discovered the strengths and weaknesses of these mobile airfields at sea, losing carriers to submarine and surface attack but also shattering the Italian battlefield in a single night with a few old torpedo bombers, as well as crippling a powerful battleship so that British battleships were able to run her down and destroy her.

But it was the battles of Pearl Harbor (December 7) and Midway (December 10) that showed just how powerful naval aviation, and by extension aircraft carriers had become. A strong Japanese carrier strike force launched two attacks that sank or damaged most of the battleships and cruisers of the US Pacific Fleet, and while Japanese aircraft losses were heavy and the Americans managed to damage a Japanese carrier with land based aircraft, the Japanese achieved their first major objective of the war in neutralizing the US Pacific Fleet for months.

Carrier Akagi (December 7, 1941)


The subsequent battle of Midway again showed the power of carrier aviation, as the Americans sank most of the Japanese invasion fleet as it approached Midway Island, stopping a powerful naval invasion, while carrier aircraft sank a carrier on each side. However the Hawaiian Islands also showed that the submarine remains a threat just as serious as aircraft, as an American carrier was knocked out the war a month after the battle, while a Japanese carrier became the third fleet carrier lost to a submarine since World War 2 began. It also showed another weakness, as both carrier fleets were forced to remain inactive for nearly 2 months to restore their badly battered air groups, and both the Americans and Japanese were forced to strip some carriers to provide sufficient aircraft and aircrew for the rest of their fleet.

which focus on specific battles and campaign of my alternate timeline Pacific War

plans are for a story "Eisenhower in the Pacific: Part 2" which will focus on the South Pacific Campaign are also underway

Some of these stories are all happening at the same time, so they are updated (or come to a conclusion) as the timeline advances

I hope you like them
 
Timeline of the Pacific War May 1937 - mid February 1942
Major Events to mid February 1942
1937-1940
Field Marshal (and Major General US Army) Douglas Macarthur is killed in a traffic accident in New York City on May 1. Major (and quickly Lieutenant Colonel) Dwight D Eisenhower becomes principal architect of the Philippine Army which is revised from Macarthur's dream of a “Switzerland in Asia” model to goals that are more realistic for the Filipino budget and likely mission post independence.

1940-41
In reaction to Japanese moves against French Indochina, the US Pacific Fleet is sent to Pearl Harbor. Admiral James Richardson strongly protests the move, but concerned that the Admiral may get himself into trouble with the President, the Secretary of the Navy convinces him to accept the situation. The Admiral then proceeds to demonstrate in Fleet Problem XXII that the most dangerous threat to Pearl Harbor is a possible air attack. This leads to changes in command for the US Army in Hawaii, as well a much stronger emphasis on air defense and long range patrolling, as well as joint Army/Navy air defense and reconnaissance headquarters.

In the Philippines, the Philippine Army gradually increases in size to several divisions, along with several engineer brigades that provide a useful adjunct to the US Army Far East. Included in this is a small but highly useful air force and a smaller but still useful coast guard. As the threat of war grows, General Krueger is sent to replace retiring General Parsons and along with him as his chief of staff is Brigadier General Eisenhower.

December 1941
The improvements by Richardson prevent the Japanese from achieving a surprise attack on Pearl Harbor, although they still inflict heavy damage to the fleet but only at the cost of roughly a third of their attack force. American counterattacks around Midway Island prevent the Japanese seizure of that strategic island. The battles December 7-10 cost the Japanese 2 fleet carriers, a heavy cruiser, and 2 destroyers sunk, numerous other ships damaged including a fleet carrier and 2 battleships, and by the end over half of the Japanese carrier aircraft have been lost, along with many aircrew. American losses are 2 battleships, 1 fleet carrier, 2 heavy cruisers, several destroyers sunk, and 4 battleships as well as several cruisers and destroyers damaged along with heavy aircraft losses.

Among the dead is Japanese Admiral Nagumo and American Admiral Richardson, while Vice Admiral Halsey is seriously injured and knocked out of the war for a year.

Meanwhile in the Philippines Japanese air attacks kill the commander of the US Asiatic Fleet, Admiral Hart, and severely wound General Krueger, leaving General Eisenhower in command of the Philippines and US Forces Far East. Ably assisted by his aviation commander, Brigadier General Chennault, the US and Filipino forces put up strong resistance before retreating carefully to Bataan, taking vast amounts of supplies with them in addition to huge stockpiles that have been prepared for the last four years. A brave action by the US Navy at Albay Gulf briefly stalls the Japanese as well but the more important role of the Navy is the evacuation of thousands of excess military personnel, civilians, and an entire Marine Regiment, as well as most of the navy support personnel both Filipino and American from the Philippines plus the evacuation of a very large part of the ground elements of the US and Filipino air forces in the Philippines to Australia.

January – February 1942
The American and Filipino forces win a defensive battle at Bataan, throwing a spanner into the works of the Japanese timetable there. At the same time an airlift from Java continues the evacuation of wounded and vital personnel from Bataan, and when Malaya falls and Singapore is placed under direct siege, that airlift force, joined by other Allied aircraft, flies thousands of civilians and some wounded out of Singapore.

A final American evacuation attempt suffers heavy losses in the Battle of the Celebes Sea, ending any further hopes for naval support and significant sea lift for the American / Filipino forces. Reinforcements, along with a new naval commander, Vice Admiral Bellenger, arrives in Australia to provide support to Eisenhower.

The Battle of the South China Sea is fought in mid February as Allied naval and air forces cover in a sacrificial action a full scale evacuation of Singapore that rivals the evacuation of Greece and Crete nearly a year before in losses and troops evacuated to safety. The battle finishes off ABDA as a viable naval surface force as well as gutting most of its air strength but over 40,000 British troops are evacuated along with thousands of civilians and many wounded. Another 10,000 British, Indian and Australian troops meant to arrive as reinforcements are rerouted to Ceylon or remain in Australia.

As of February 12, the final battle for Singapore is imminent while elsewhere the Japanese are invading Burma and have seized much of the Eastern Dutch East Indies, and are about to invade Sumatra and Java and Timor are next. In the Philippines the Americans still hold most of the islands outside of Luzon except for southern Mindanao, and in continue to remain well dug in at Bataan and Corregidor.

General Eisenhower is on his way to Washington DC to consult with the President, as well as the Secretary of War and Army Chief of Staff, while Admiral Nimitz is in command of the Pacific Fleet and is already getting ready for the first Pacific Fleet offensive of the war.

Coming soon in mid February 1942, a massive Japanese carrier and land based air attack on Darwin, a British carrier airstrike on the Japanese invasion fleet heading for Sumatra, and the first US Carrier raids of the war in the Marshall Islands

Although not before the weekend most likely....

If history (real or alternate) can be compared to the flow of a river, then GB has a nifty braided channel in the works here. Love it!
 
What is the gigantic "vent" on the side there?

As Alspug said its a funnel, only two Japanese carriers had a traditional bridge/funnel layout that you'd expect of a USN or RN carrier and this was the Shiano and Taiho. The rest had their funnels venting over the side

here for example you can (just) see the funnel layout for the Shokaku class, again bent over the side, pointing down towards the sea.
 
I always wondered about this unique bit of design. While, in theory, it reduces the potential for exhaust reducing visibility over the flight deck and/or turbulence there, how does this design affect the efficiency of both exhaust and downdraft for the engines.
