The Keystone B-5 is a light bomber made by the Keystone Aircraft company for the United States Army Air Corps in the early 1930s. The B-5A was a Keystone B-3A with Wright Cyclone rather than Pratt & Whitney engines.
|Primary user||United States Army Air Corps|
|Number built||3 Y1B-5|
|Developed from||Keystone B-3|
Three B-3A (LB-10A) were reengined with Wright R-1750-3 radial engines and were redesignated Y1B-5. The Army Air Corps changed the design of the last 27 LB-10As on order, replacing the Pratt & Whitney R-1690 radial engines with the Wright R-1750-3. The Pratt & Whitney-powered aircraft were designated B-3A, and the Wright-powered aircraft became B-5A. They provided the backbone of the U.S. bomber force from then to 1934.
B-5A were first line bombers of the United States for the period between 1930 and 1934. Afterwards, they remained in service primarily as observation aircraft until the early 1940s.
Not to be confused with XX Bomber CommandThe 20th Bomb Squadron is a unit of the 2d Operations Group of the United States Air Force located at Barksdale Air Force Base, Louisiana. The 20th is equipped with the Boeing B-52H Stratofortress.
Formed in May 1917 as the 20th Aero Squadron, the squadron saw combat in France on the World War I Western Front. It took part in the St. Mihiel offensive and Meuse-Argonne offensive.
After the war, it served with the Army Air Service and Army Air Corps as the 20th Bombardment Squadron During the 1920s and 1930s, the squadron was involved in field service testing of new bomber aircraft, notably the Y1B-17 Flying Fortress.
During World War II the squadron fought in the North African and Italian Campaigns. It was awarded a Distinguished Unit Citation for its actions during a raid on Steyr, Austria.
It was a part of Strategic Air Command during the Cold War. As a medium bomber squadron it deployed to stand alert at forward bases in "Reflex" operations. After equipping with Boeing B-52 Stratofortresses stood nuclear alert, but during the Viet Nam War the squadron deployed frequently to perform Operation Arc Light bombing missions. Since 1993, the 20th Bomb Squadron has flown the B-52H Stratofortress long-range strategic bomber, which can perform a variety of missions. Today the squadron is engaged in the Global War on Terrorism.23rd Bomb Squadron
The 23rd Bomb Squadron is a United States Air Force unit, assigned to the 5th Bomb Wing. It is stationed at Minot Air Force Base, North Dakota. The mission of the squadron is to fly the Boeing B-52H Stratofortress strategic bomber. The squadron stands ready to deploy and fly its B-52Hs to enforce national security policy by being ready to deliver overwhelming nuclear or conventional firepower to destroy targets, worldwide, at any time.
The squadron is one of the oldest in the United States Air Force, dating to 16 June 1917, when it was organized at Kelly Field, Texas. It deployed to England as part of the American Expeditionary Forces, being engaged as an aircraft repair squadron during World War I. The squadron saw combat during World War II, and became part of the Strategic Air Command (SAC) during the Cold War.42nd Attack Squadron
The 42d Attack Squadron of the United States Air Force flies General Atomics MQ-9 Reaper Unmanned aerial vehicles and is currently stationed at Creech Air Force Base near Indian Springs, Nevada. The 42d oversees the training and combat deployment of aerial vehicle and sensor operators assigned to the Reaper. All aircraft will employ the AN/AAS-52 Multi-Spectral Targeting System developed by Raytheon.72nd Test and Evaluation Squadron
The 72d Test and Evaluation Squadron is part of the 53d Wing at Eglin Air Force Base, Florida. The squadron is geographically separated but operated from Whiteman Air Force Base, Missouri. It conducts testing and evaluation of the B-2 Spirit aircraft.96th Bomb Squadron
The 96th Bomb Squadron is a unit of the United States Air Force 2d Operations Group located at Barksdale Air Force Base, Louisiana. The 96th is equipped with the Boeing B-52H Stratofortress.
Formed in August 1917, the 96 BS saw combat on the World War I Western Front, in France. It took part in the St. Mihiel offensive and Meuse-Argonne offensive. Later, it served with the Army Air Service and Army Air Corps in the Inter-War period it participated in Brig. Gen. Billy Mitchell's 1921 off-shore bombing tests and during World War II fought in the North African and Italian Campaigns. It was a part of Strategic Air Command during the Cold War. Since 1993, the 96th Bomb Squadron has flown the B-52H Stratofortress long-range heavy bomber, which can perform a variety of missions. Today the squadron is engaged in the Global War on Terrorism.Keystone Aircraft
Keystone Aircraft Corporation was an early pioneer in airplane manufacturing. Headquartered in Bristol, Pennsylvania, it was formed as Ogdensburg Aeroway Corp in 1920 by Thomas Huff and Elliot Daland, but its name was quickly changed to Huff-Daland Aero Corp, then to the Huff-Daland Aero Company. The company made a name for itself in agricultural aircraft, and then in the United States Army Air Corps' early bomber aircraft. From 1924, James McDonnell was the chief designer.
In 1926, Huff left the company, and it was soon purchased by Hayden, Stone & Co., who increased capital to $1 million (United States) and renamed it Keystone. In 1928, it merged with Loening and was known as Keystone-Loening. In 1929, it was taken over by Curtiss-Wright. Also in 1929, the Keystone- Loening plant on the East River in New York City was closed by Curtis- Wright and the operation was moved to the Bristol, Pa. Keystone plant. A small band of the top Loening management, design and shop workers (all New Yorkers) did not want to go to Bristol. They instead started their own aircraft company in a small rented shop in Baldwin, NY in Jan. 1930. The principal players were Leroy R. Grumman, Leon "Jake" Swirbul and William Schwendler. Grumman Aircraft went on to stellar heights with some of the top Naval aircraft in Navy history. Grumman also designed and built the Lunar Excursion Module (LEM) that landed US astronauts on the moon. Keystone itself became a manufacturing division of Curtiss-Wright and ceased production in 1932.Lieut. Comdr. Noel Davis and Lieut. Stanton H. Wooster were killed in their Keystone Pathfinder American Legion while conducting a test flight, just days before they were to attempt a trans-Atlantic flight for the Orteig Prize.Keystone B-3
The Keystone B-3A was a bomber aircraft developed for the United States Army Air Corps by Keystone Aircraft in the late 1920s.Keystone B-4
The Keystone B-4 was a biplane bomber, built by the Keystone Aircraft company for the United States Army Air Corps.Keystone B-6
The Keystone B-6 was a biplane bomber developed by the Keystone Aircraft company for the United States Army Air Corps.Keystone LB-6
The Keystone LB-6 and LB-7 were 1920s American light bombers, built by the Keystone Aircraft company for the United States Army Air Corps, called Panther by the company, but adoption of the name was rejected by the U.S. Army.List of Interwar military aircraft
Interwar military aircraft are military aircraft that were developed and used between World War I and World War II, also known as the Golden Age of Aviation.
For the purposes of this list this is defined as aircraft that entered service into any country's military after the armistice on 11 November 1918 and before the Invasion of Poland on 1 September 1939.
Aircraft are listed alphabetically by their country of origin. Civilian aircraft modified for military use are included but those that remained primarily civilian aircraft are not.List of United States bomber aircraft

The following is a list of bomber airplanes and does not include bomber airships, organized by era and manufacturer. A bomber is a military aircraft designed to attack ground or sea targets.List of military aircraft of the United States
This list of military aircraft of the United States includes prototype, pre-production, and operational types. For aircraft in service, see the list of active United States military aircraft. Prototypes are normally prefixed with "X" and are often unnamed (note that these are not the same as the experimental X-planes, which are not generally expected to go into production), while pre-production models are usually prefixed with "Y".
The United States military employs a designation and naming system to provide identifications to all aircraft types. Until 1962, the United States Army, United States Air Force (formerly Army Air Force), and United States Navy all maintained separate systems. In September 1962, these were unified into a single system heavily reflecting the Air Force method. For more complete information on the workings of this system, refer to United States Department of Defense Aerospace Vehicle Designations.
This list does not include aircraft used by the U.S. military services prior to the establishment of a numerical designation system. For these aircraft, see List of military aircraft of the United States (1909–1919). It also does not include aircraft designated under the pre-1962 United States Navy designation system. For these aircraft, see List of military aircraft of the United States (naval).
