Vozdvizhenka is an air base in Primorsky Krai located close to the village of Vozdvizhenka.
 This base was dedicated to Pacific heavy long-range bomber fleet, housing the 444th Berlin Order of Kutuzov 3rd degree and Alexander Nevsky Heavy Bomber Aviation Regiment, part of the 326th Heavy Bomber Aviation Division, 37th Air Army.
Henry Eugene "Red" Erwin, Sr., (May 8, 1921 – January 16, 2002) was a United States Army Air Forces airman and a recipient of the U.S. military's highest decoration—the Medal of Honor—for his actions in World War II.
 He earned the award as a staff sergeant and radio operator aboard a B-29 Superfortress in the Asia-Pacific theater.
 During a 1945 bombing mission over Koriyama, Japan, a white phosphorus bomb prematurely ignited in his aircraft and seriously wounded him.
 As smoke filled the plane, he picked up the burning device and carried it through the aircraft to the cockpit where he tossed it out a window.
 Although he suffered severe burns, he successfully saved his plane and all crew members aboard by disposing of the incendiary/smoke-generating bomb.
The Fiat BRG was an Italian heavy bomber prototype built by Fiat for the Italian Air Force.
 The BRG ("Bombardiere Rosatelli Gigante", "Giant Rosatelli Bomber") was a three-engine strut-braced high-wing monoplane.
 It had a deep slab-sided fuselage with one engine in the nose and two strut-mounted engines between the upper wing and a short stub wing attached to the lower fuselage.
 The BRG had a single fin and rudder and a wide-track landing gear.
 The pilot and co-pilot had a cabin forward of the wing leading edge.
 The aircraft was fitted with four machine guns, located in an open dorsal cockpit and a ventral tunnel.
 After testing in 1931 the prototype BRG was attached to 62 "Squadriglia" SPB, an experimental heavy bomber squadron.
The Tupolev TB-3 (Russian: Тяжёлый Бомбардировщик , Tyazholy Bombardirovschik, Heavy Bomber, civilian designation ANT-6) was a heavy bomber aircraft which was deployed by the Soviet Air Force in the 1930s and during World War II.
 It was the world's first cantilever wing four-engine heavy bomber.
 Despite obsolescence and being officially withdrawn from service in 1939, the TB-3 performed bomber and transport duties throughout much of World War II.
 The TB-3 also saw combat as a Zveno project fighter mothership and as a light tank transport.
The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC).
 Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry (prototype Model 299/XB-17) outperformed both competitors and exceeded the air corps' performance specifications.
 Although Boeing lost the contract (to the Douglas B-18 Bolo) because the prototype crashed, the air corps ordered 13 more B-17s for further evaluation.
 From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances, becoming the third-most produced bomber of all time, behind the B-24 and the multirole Ju 88.
The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing, which was flown primarily by the United States during World War II and the Korean War.
 It was one of the largest aircraft operational during World War II and featured state of the art technology.
 Including design and production, it was the single most expensive weapons project undertaken by the United States in World War II, exceeding the cost of the Manhattan Project by between $1 and 1.7 billion.
 Innovations introduced included a pressurized cabin, dual-wheeled, tricycle landing gear, and an analog computer-controlled fire-control system that directed four remote machine gun turrets that could be operated by a single gunner and a fire-control officer.
 A manned tail gun installation was semi-remote.
 The name "Superfortress" continued the pattern Boeing started with its well-known predecessor, the B-17 Flying Fortress.
 Designed for the high-altitude strategic bomber role, the B-29 also excelled in low-altitude nighttime incendiary bombing missions.
 One of the B-29's final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki.
The Tupolev ANT-16 (also known as the TB-4; Russian: Тяжелый Бомбардировщик – "Heavy Bomber") was an experimental heavy bomber aircraft designed and tested in the Soviet Union in the early 1930s.
 Conceptually representing evolution of the TB-3 bomber, the ANT-16 was designed under the doctrine that size and payload were more important for a bomber than speed because it would be able to protect itself with defensive armament.
 The twin 5 × bomb bays were the largest in the world at that time and presented many design challenges in order to preserve structural rigidity of the airframe.
The Eighth Air Force (8 AF) is a numbered air force (NAF) of the United States Air Force Global Strike Command (AFGSC).
 It is headquartered at Barksdale Air Force Base, Louisiana.
 The command serves as Air Forces Strategic – Global Strike, one of the air components of United States Strategic Command (USSTRATCOM).
 The Eighth Air Force includes the heart of America's heavy bomber force: the B-2 Spirit stealth bomber, the B-1 Lancer supersonic bomber, and the B-52 Stratofortress heavy bomber aircraft.
The Bomber Mafia were a close-knit group of American military men who believed that long-range heavy bomber aircraft in large numbers were able to win a war.
 The derogatory term 'Bomber Mafia' was used before and after World War II by those in the military who did not share their belief, and who were frustrated by the insistence of the men that the heavy bomber should take a primary position in planning and funding.
"Kampfgeschwader" 40 (KG 40) was a Luftwaffe medium and heavy bomber wing of World War II, and the primary maritime patrol unit of any size within the World War II Luftwaffe.
 It is best remembered as the unit operating a majority of the four-engine Focke-Wulf Fw 200 "Condor" maritime patrol bombers.
 The unit suffered from the poor serviceability and low production rates of the Fw 200 bombers, and from repeated diversion of its long-haul capability aircraft to undertake transport duties in various theatres, especially for the airlift operations to supply encircled forces in the Battle of Stalingrad.
 Later in the war, KG 40 became one of several Luftwaffe bomber wings to use the Heinkel He 177A heavy bomber.
