When did the first specially designed fighter bomber appear?

The F-105 Lei Gong fighter-bomber was the first supersonic tactical fighter-bomber in the U.S. Air Force, and it was also the largest single-seat, single-engine combat aircraft ever built by the U.S. Air Force, and was known for its large interior capsule and unique forward-swept engine air intakes under the wing roots.

The F-105 is a single-seat supersonic fighter-bomber developed as a successor to the F-84. In the early 50s, the strategic thinking of the United States was based on fighting a nuclear war, and the tactical air force should also have a tactical nuclear bombing capability. Therefore, in the planning of the F-105, the main task is to carry out tactical nuclear attacks, and it can also carry out conventional bombs to carry out ground attack missions, and has a certain self-defense air combat capability.

In 1951, the Republic Corporation of the United States began to design the F-105, and in 1952, the U.S. Air Force signed a contract with the company for the development of the prototype YF-105A, and on October 22, 1955, the first YF-105A (a total of two) flew with a Pratt Whitney J57-P-25 engine. However, on the F-105B-1 aircraft that appeared in May 1956, the results of NACA's extensive transonic research on the F-100 series aircraft were adopted, and the design modifications were made according to the requirements of the area law. Subsequently, the F-105B went into mass production, which was equipped with troops in 1958.

In 1957, the U.S. Air Force further developed an all-weather modification of the F-105D, which was equipped with troops in 1960. The F-105 was discontinued in 1965. In the Vietnam War, the tasks of the F-105 were gradually replaced by the F-111.

By 1984, all F-105s were withdrawn from active service. Although the F-105 is a fighter-bomber, it is mainly used for ground attack and has poor air combat performance.

China's research on bombers has not fallen, the H-6 bomber is the representative of the domestic bomber, in these decades, it is China's most powerful strategy, China's most powerful bomber compared with the world's excellent bombers, it does not have much advantage.

A fighter is a fighter plane, which is used to carry out the task of destroying enemy aircraft in the air, while a bomber is an aircraft used to bomb targets on the ground and water. Difference between combat objectives: Fighter aircraft are military aircraft, also known as fighters, that are used to destroy enemy planes and other flying aircraft in the air to change from air attack weapons.

Attack aircraft are mainly used to directly support ground forces (surface ship units) by attacking the enemy's tactical defense and small targets in the depth of shallow and close campaigns from low and ultra-low altitudes. Bombers are used to bomb ground and surface targets.

Fighters:Fighter aircraft belong to a type of fighter plane, that is, a military aircraft used to destroy enemy aircraft and other flying air attack weapons in the air. During the Second World War, it was widely known as the destroyer.

The main task of the fighter is to engage in air combat with enemy fighters and seize air superiority (air supremacy). The second is to intercept enemy bombers, attack planes and cruise missiles, and can also carry a certain number of ground attack missions to carry out ground attack missions. Fighters include interceptors for air defense in important areas, but since the 60s of the 20th century.
