Martin T5M
The Martin BM was a 1930s American torpedo bomber built by the Glenn L. Martin Company for the United States Navy. Design and development To meet the requirement for a special-purpose dive bomber for the United States Navy and United States Marine Corps, the US Navy's Bureau of Aeronautics designed a biplane with fixed tailwheel landing gear, designated Bureau Design 77. It had room for two crew in tandem. Two prototypes were ordered in June 1928, one from Martin (designated the XT5M-1) and one from the Naval Aircraft Factory (designated the XT2N-1). The Martin XT5M-1 was powered by a Pratt & Whitney R-1690-22 Hornet The Pratt & Whitney R-1690 Hornet was a widely used American aircraft engine. Developed by Pratt & Whitney, 2,944 were produced from 1926 through 1942. It first flew in 1927. It was a single-row, 9-cylinder air-cooled radial design.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Dive Bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Bomber
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'', and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedoes specifically designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as , more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it usually needed to be specially designed ...

United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the United States Navy is the third largest of the United States military service branches in terms of personnel. It has 290 deployable combat vessels and more than 2,623 operational aircraft . The United States Navy traces its origins to the Continental Navy, which was established during the American Revo ...

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...

Bureau Of Aeronautics
The Bureau of Aeronautics (BuAer) was the U.S. Navy's material-support organization for naval aviation from 1921 to 1959. The bureau had "cognizance" (''i.e.'', responsibility) for the design, procurement, and support of naval aircraft and related systems. Aerial weapons, however, were under the cognizance of the Navy's Bureau of Ordnance (BuOrd). Origins The USN's first attempt for naval aviation began in 1908 when it conducted observations of the Wright Brothers aircraft at Fort Myer, Virginia.https://www.history.navy.mil/content/dam/nhhc/research/histories/naval-aviation/pdf/History%20(1).pdf First tests and Naval Aviation Corps The first test of an aircraft from naval vessel was in 1910 when a Curtiss Model D flown by Eugene Burton Ely took off from the USS Birmingham (CL-2) and again on USS Pennsylvania (ACR-4) in early 1911. These test was enough for the USN to establish naval aviation units in the summer of 1911. The purchase of the first naval aircraft in May 1911 and ...

Naval Aircraft Factory
The Naval Aircraft Factory (NAF) was established by the United States Navy in 1918 in Philadelphia, Pennsylvania. It was created to help solve aircraft supply issues which faced the Navy Department upon the entry of the U.S. into World War I. The US Army’s requirements for an enormous quantity of airplanes created a decided lack of interest among aircraft manufacturers in the Navy's requirements for a comparatively small quantity of aircraft. The Navy Department concluded that it was necessary to build a Navy-owned aircraft factory in order to assure a part of its aircraft supply; to obtain cost data for the department’s guidance in its dealings with private manufacturers; and to have under its own control a factory capable of producing experimental designs. History On 27 July 1917, Secretary of the Navy Josephus Daniels approved the construction of the Naval Aircraft Factory, as a means for the government to promote industry efficiency, ensure engineering expertise, and ...
