Le Convair B-36 Il "Peacemaker" era un bombardiere strategico costruito dalla Convair e operato esclusivamente dalla United States Air Force (USAF) dal 1949 al 1959. Il B-36 è stato il più grande aereo con motore a pistoni prodotto in serie mai realizzato. Aveva l'apertura alare più lunga di qualsiasi aereo da combattimento mai costruito, a 230 piedi (70,1 m). Il B-36 è stato il primo bombardiere in grado di fornire una qualsiasi delle armi nucleari nell'arsenale degli Stati Uniti dall'interno dei suoi quattro vani bomba senza modifiche agli aerei. Con una portata di 10.000 mi (16.000 km) e un carico utile massimo di 87.200 lb (39.600 kg), il B-36 è stato il primo bombardiere con equipaggio al mondo in grado di volare intercontinentalmente senza rifornimento.
Le Convair B-36 Pacificatoreremains the largest mass-produced piston-engined aircraft ever built. With a wingspan longer than the Wright brothers’ first flight, it was designed during WWII to bomb Nazi Germany directly from the United States should Britain fall. By the time it entered service in 1948, it became the primary delivery vehicle for the Strategic Air Command’s nuclear arsenal. It was the only aircraft capable of carrying the massive 42,000-lb Mark 17 hydrogen bomb, serving as a terrifyingly large symbol of American power until the arrival of the B-52.

The Pusher Configuration:The B-36 used six massive R-4360 radial engines mounted backwards. This “pusher” arrangement reduced turbulence over the wings and improved cooling airflow, though it led to frequent engine fires due to carburetor icing in the intake ducts.
Jet Augmentation:Starting with the D-model, four J47 jet engines were added in pods near the wingtips. These were used for shorter takeoff rolls and high-speed dashes over the target. This led to the famous crew phrase:“Six turning and four burning.”
The Magnesium Skin:To save weight on such a colossal airframe, much of the fuselage skin was made of magnesium alloy rather than aluminum. This made the aircraft exceptionally light for its size but also meant it was highly flammable if it caught fire.
Communication Tunnel:Because the bomb bays were so large, they divided the pressurized crew compartments. To get from the front (cockpit) to the rear (gunner/bunk) stations, crew members had to lie on a wheeled trolley and pull themselves through an 85-foot long pressurized tunnel.
Legacy: The Giant That Never Fired a Shot in Anger
Strategic Deterrent:The B-36 never dropped a bomb in combat. Its mere existence was its mission—proving to the Soviet Union that the U.S. could strike any target on the globe without needing overseas bases.
The NB-36H Nuclear Test:One B-36 was modified to carry a live, shielding-protected nuclear reactor in its bomb bay to test the feasibility of nuclear-powered flight. It flew 47 times, though the reactor only powered itself, not the aircraft.
FICON Project:Due to its lack of speed, the B-36 was used as a “mother ship” to carry an F-84 Thunderjet fighter in its bomb bay. The fighter could be launched to defend the bomber and then re-attached in mid-air.
The Featherweight Program:Toward the end of its life, many B-36s were stripped of all defensive turrets and extra equipment to allow them to fly at altitudes above 50,000 feet, where early Soviet interceptors could not reach them.
