Question: What widely used on aircraft in the 1930s through 1950s was the result of the development of the M-25?
Context: The Wright R-1820 Cyclone 9 was an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s.  It was produced under license in Spain as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25. The Lockheed F-104 Starfighter is a single-engine, supersonic interceptor aircraft which later became widely used as an attack aircraft.  It was originally developed by Lockheed for the United States Air Force (USAF), but became widely used by US Allies around the world, and produced by several other NATO nations.  One of the Century Series of fighter aircraft, it was operated by the air forces of more than a dozen nations from 1958 to 2004.  Its design team was led by Kelly Johnson, who contributed to the development of the Lockheed P-38 Lightning, Lockheed U-2, Lockheed SR-71 Blackbird and other Lockheed aircraft. The Shvetsov ASh-82 (M-82) is a Soviet 14-cylinder, two-row, air-cooled radial aircraft engine developed from the Shvetsov M-62.  The M-62 was the result of development of the M-25, which was a licensed version of the Wright R-1820 Cyclone. The Shvetsov M-25 was an aircraft radial engine produced in the Soviet Union (USSR) in the 1930s and 1940s, a licensed production variant of the Wright R-1820-F3. The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s.  These engines have a displacement of 985 in3 ; initial versions produced 300 hp , while the most widely used versions produce 450 hp . The aircraft diesel engine or aero diesel has not been widely used as an aircraft engine.  Diesel engines were used in airships and were tried in aircraft in the late 1920s and 1930s, but never widely used.  Their main advantages are their excellent specific fuel consumption and the somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines.  The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in early 2010s. The HS.404 is an autocannon originally designed and produced by Hispano-Suiza.  It was widely used as both an aircraft, naval and land based weapon in the 20th century by French, British, American and numerous other military services, particularly during the Second World War.  The cannon is also referred to as Birkigt type 404, after its designer Marc Birkigt, and later versions based on British development are known as 20mm Hispano.  Firing a 20 mm calibre projectile, it delivered a useful load of explosive from a relatively light weapon.  This made it an ideal anti-aircraft weapon for mounting on light vehicles, as well as a fighter aircraft gun, replacing the multiple 7.62 mm (.30 calibre) and .303 inch (7.7 mm) machine guns commonly used in military aircraft of the 1930s.  The HS.404 was produced by the French subsidiary of Hispano-Suiza. France has used many military aircraft both in its air force, the Armée de l'Air, and other branches of its armed forces.  Numerous aircraft were designed and built in France, but many aircraft from elsewhere, or part of joint ventures have been used as well.  Lighter-than-air aircraft such as dirigibles and balloons found use starting in the 19th century used mainly for observation.  The advent of World War I saw an explosion in the number France's aircraft, though development slowed after.  While having many promising designs in development in the 1930s, government wrangling delayed development enough there was little available at the out break of World War II.  The armistice in 1940 marked a low point, with Vichy France being allowed only reduced numbers and development halting.  Many French aircraft were captured and used by the Third Reich and its allies.  Some aircraft that did escape served with the Allies or Free French forces, who also used many other types of allied aircraft.  The cold-war saw the continued use of many other Western aircraft, mainly from the U.S., during a period of rebuilding of the aviation industry and under threat of war with the Soviet Union.  Many new types would come into service including the very successful Mirage series or the latest design, the Rafale. The McDonnell FH Phantom was a twin-engined jet fighter aircraft designed and first flown during World War II for the United States Navy.  The Phantom was the first purely jet-powered aircraft to land on an American aircraft carrier and the first jet deployed by the United States Marine Corps.  Although with the end of the war, only 62 FH-1s were built, it helped prove the viability of carrier-based jet fighters.  As McDonnell's first successful fighter, leading to the development of the follow-on F2H Banshee, which was one of the two most important naval jet fighters of the Korean War, it would also establish McDonnell as an important supplier of Navy aircraft.  When McDonnell chose to bring the name back with the Mach 2–class McDonnell Douglas F-4 Phantom II, it launched what would become the most versatile and widely used western combat aircraft of the Vietnam War era, adopted by the USAF and the US Navy. The Continental R-670 (factory designation W670) was a seven-cylinder four-cycle radial aircraft engine produced by Continental displacing 668 cubic inches (11 litres) and a dry weight of 465 lb .  Horsepower varied from 210 to 240 at 2,200 rpm.  The engine was the successor to Continental's first radial engine, the 170 hp Continental A-70.  This engine was used on many aircraft in the 1930s and 1940s.  The R-670 was widely used in the PT-17 Stearman primary training aircraft of the U.S. military.
