Title: “Mizuho-Jap Av”

This original World War II ship identification poster comes from the identification binder of a WWII Navy carrier pilot D. Fitzgerald. This poster was used by Fitzgerald and other U.S. carrier and Allied pilots to identify both Allied and Axis ships and aircraft. Combatants in war have consistently bombed and shot at their own ships and aircraft out of unfamiliarity of their shape and design. Thus, becoming familiar with the general layout of both Allied and enemy ships was a vital skill Allied intelligence sought to solve over the course of World War II. As a result of this, friendly fire intelligence resources such as ID posters, binders, and booklets were created to differentiate friend from foe. Whether you were a pilot flying combat missions or a sailor aboard any type of U.S. ship classes, the objective of all seagoing and air personnel was set to be able to recognize important aircraft, ships or ship types at a glance. Thus, familiarity with the details of naval and aircraft design illustrated in the following page proved of value to the student of ship identification.

Mizuho:

Mizuho (瑞穂, "Fresh Grain") was a seaplane carrier of the Imperial Japanese Navy during World War II. The ship was built at Kawasaki Shipbuilding at Kobe, Japan, and was completed in February 1939.

Mizuho was built to a similar design as the seaplane carrier Chitose, but with slightly less powerful diesel engines instead of Chitose's turbines. She carried 24 seaplanes, and was equipped to carry twelve miniature submarines, although she could not carry full loads of both at one time.

Mizuho participated in invasion support for much of her career; her first mission was with the Fourth Surprise Attack Force. On 1 March 1942, planes from Mizuho and Chitose damaged the American destroyer USS Pope, which was later sunk by aircraft from the aircraft carrier Ryūjō and gunfire from the heavy cruisers Ashigara and Myōkō.

Naval Aviation during WWII:

World War II saw the emergence of naval aviation as the decisive element in the war at sea. The principal users were Japan, United States (both with Pacific interests to protect) and Britain. Germany, the Soviet Union, France and Italy had a lesser involvement. Soviet Naval Aviation was mostly organised as land-based coastal defense force (apart from some scout floatplanes it consisted almost exclusively of land-based types also used by its air arms).

During the course of the war, seaborne aircraft were used in fleet actions at sea (Midway, Bismarck), strikes against naval units in port (Taranto, Pearl Harbor), support of ground forces (Okinawa, Allied invasion of Italy) and anti-submarine warfare (the Battle of the Atlantic). Carrier-based aircraft were specialised as dive bombers, torpedo bombers, and fighters. Surface-based aircraft such as the PBY Catalina helped finding submarines and surface fleets.

In World War II the aircraft carrier replaced the battleship as the most powerful naval offensive weapons system as battles between fleets were increasingly fought out of gun range by aircraft. The Japanese Yamato, the most powerful battleship ever built, was first turned back by light escort carrier aircraft and later sunk lacking its own air cover.

During the Doolittle Raid of 1942, 16 Army medium bombers were launched from the carrier Hornet on one-way missions to bomb Japan. All were lost to fuel exhaustion after bombing their targets and the experiment was not repeated. Smaller carriers were built in large numbers to escort slow cargo convoys or supplement fast carriers. Aircraft for observation or light raids were also carried by battleships and cruisers, while blimps were used to search for attack submarines.

Experience showed that there was a need for widespread use of aircraft which could not be met quickly enough by building new fleet aircraft carriers. This was particularly true in the North Atlantic, where convoys were highly vulnerable to U-boat attack. The British authorities used unorthodox, temporary, but effective means of giving air protection such as CAM ships and merchant aircraft carriers, merchant ships modified to carry a small number of aircraft. The solution to the problem were large numbers of mass-produced merchant hulls converted into escort aircraft carriers (also known as "jeep carriers"). These basic vessels, unsuited to fleet action by their capacity, speed and vulnerability, nevertheless provided air cover where it was needed.

The Royal Navy had observed the impact of naval aviation and, obliged to prioritize their use of resources, abandoned battleships as the mainstay of the fleet. HMS Vanguard was therefore the last British battleship and her sisters were cancelled. The United States had already instigated a large construction program (which was also cut short) but these large ships were mainly used as anti-aircraft batteries or for shore bombardment.
