A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto, the sinking of the German battleship Bismarck, the sinking of the British battleship HMS Prince Of Wales and the British battlecruiser HMS Repulse and the Japanese attack on Pearl Harbor.
A warship or combatant ship is a ship that is used for naval warfare. Usually they belong to the navy branch of the armed forces of a nation, though they have also been operated by individuals, cooperatives and corporations. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew.
A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War.
USS Columbia was a Cleveland-class light cruiser of the United States Navy, which were built during World War II. The class was designed as a development of the earlier Brooklyn-class cruisers, the size of which had been limited by the First London Naval Treaty. The start of the war led to the dissolution of the treaty system, but the dramatic need for new vessels precluded a new design, so the Clevelands used the same hull as their predecessors, but were significantly heavier. The Clevelands carried a main battery of twelve 6-inch (152 mm) guns in four three-gun turrets, along with a secondary armament of twelve 5 in (127 mm) dual-purpose guns. They had a top speed of 32.5 knots.
The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear.
Chikuma (筑摩) was the second and last vessel in the Tone class of heavy cruisers in the Imperial Japanese Navy. The ship was named after the Chikuma River in Nagano Prefecture. Entering service in 1939, Chikuma saw battle during World War II in the Pacific, hunting small allied ships in the Indian Ocean and serving in many escorting missions throughout many large-scale aircraft carrier battles between Japan and the United States. On the 25 of October 1944, she served in the Battle off Samar where she possibly sank the escort carrier USS Gambier Bay and damaged the destroyer USS Heermann, before being crippled by gunfire from the destroyer escort USS Samuel B. Roberts and sunk by air attacks.
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. It often involves navalised aircraft, specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators.
USS Williamson (DD-244/AVP-15/AVD-2/APD-27) was a Clemson-class destroyer in the United States Navy during World War II. She was named for Commander William Price Williamson.
A submarine aircraft carrier is a submarine equipped with aircraft for observation or attack missions. These submarines saw their most extensive use during World War II, although their operational significance remained rather small. The most famous of them were the Japanese I-400-class submarines and the French submarine Surcouf, although small numbers of similar craft were built for other nations' navies as well.
The Curtiss SOC Seagull was an American single-engined scout observation seaplane, designed by Alexander Solla of the Curtiss-Wright Corporation for the United States Navy. The aircraft served on battleships and cruisers in a seaplane configuration, being launched by catapult and recovered from a sea landing. The wings folded back against the fuselage for storage aboard ship. When based ashore or on carriers the single float was replaced by fixed wheeled landing gear.
The two Tone-class cruisers were the last heavy cruisers completed for the Imperial Japanese Navy. The Tone-class cruisers were originally envisaged as the 5th and 6th vessels in the Mogami class. However, by the time construction began, serious weaknesses in the Mogami-class hull design had become clear following the Fourth Fleet incident in 1935. As Japan no longer was obligated to abide by the limitations of the London Naval Treaty, a new design was created and new means of construction were utilized. Although the external dimensions were close to the Mogami class, the design was quite different, with all the main battery of guns placed forward of the bridge, reserving the entire stern area as a large seaplane operations deck. Unlike the U.S. Navy, the Japanese did not have a dual role attack/scout aircraft, nor did they assign any of their carrier aircraft to a reconnaissance role. Little emphasis was placed on this aspect of carrier warfare. Instead the Japanese reserved all of their carrier aircraft for attack roles. Reconnaissance then was relegated to the float planes carried by cruisers. The Tone and the Chikuma were intended to provide the long range reconnaissance needed for Japan's carrier Air Fleets.
The aircraft cruiser is a warship that combines the features of the aircraft carrier and a surface warship such as a cruiser or battleship.
Chiyoda was a light aircraft carrier of the Imperial Japanese Navy during World War II. Originally constructed as the second vessel of the Chitose-class seaplane tenders in 1934, she continued to operate in that capacity during the Second Sino-Japanese War and the early stages of the Pacific War until her conversion into a light aircraft carrier after the Battle of Midway. She was sunk during the Battle of Leyte Gulf by a combination of naval bombers, cruiser shellfire and destroyer-launched torpedoes.
A fleet carrier is an aircraft carrier designed to operate with the main fleet of a nation's navy. The term was developed during World War II, to distinguish it from the escort carrier and other less capable types. In addition to many medium-sized carriers and supercarriers, some light carriers are also classed as fleet carriers.
Aircraft carriers are warships that evolved from balloon-carrying wooden vessels into nuclear-powered vessels carrying many dozens of fixed- and rotary-wing aircraft. Since their introduction they have allowed naval forces to project air power great distances without having to depend on local bases for staging aircraft operations.
The flight-deck cruiser was a proposed type of aircraft cruiser,, designed by the United States Navy during the Interwar period. Several designs were proposed for the type, but none was approved for construction. The final design was developed just before World War II, and the entry of the United States into the war saw the project come to an end.
The Vought XSO2U was an American observation floatplane developed by Vought-Sikorsky for the United States Navy during the late 1930s. Intended to replace the Curtiss SOC Seagull in service as a scout aboard cruisers, it proved superior to the Curtiss SO3C in evaluation, but failed to win a production contract due to Vought's lack of manufacturing capacity.
Observation seaplanes are military aircraft with flotation devices allowing them to land on and take off from water. Their primary purpose was to observe and report enemy movements or to spot the fall of shot from naval artillery, but some were armed with machineguns or bombs. Their military usefulness extended from World War I through World War II. They were typically single-engine machines with catapult-launch capability and a crew of one, two or three. Most were designed to be carried aboard warships, but they also operated from seashore harbors.
The Interdiction Assault Ship (IAS) was an aircraft cruiser conversion project in 1980 for the Iowa-class battleships that would have removed the aft main gun turret. This would free up space for a V-shaped ramped flight deck, while a new hangar would be added with two elevators, which would support up to twelve McDonnell Douglas AV-8B Harrier II jump-jets. These aviation facilities could also support helicopters, SEAL teams and up to 500 Marines for an air assault. In the empty space between the V flight deck would be up to 320 missile silos accommodating a mixture of Tomahawk land attack missiles, ASROC anti-submarine rockets and Standard surface-to-air missiles. The existing five-inch gun turrets would be replaced with 155-millimeter howitzers for naval gunfire support. These modifications would have required significant time and funding to achieve so it was never carried out. Furthermore, the Department of Defense and the Navy wanted the Iowa battleships reactivated as quickly as possible.
Carrier Aircraft Service Units (CASU) were United States Navy units formed during World War II for the Pacific War to support naval aircraft operations. From 1942 to 1946, 69 Carrier Aircraft Service Units were formed to repair and maintain aircraft. The first unit was deployed to Naval Station Pearl Harbor. The CASU-11, was deployed on January 22, 1943 at Naval Air Station San Diego. During the war the Navy lacked enough aircraft carriers to complete all the operational requirements.
