The Grumman A-6 Intruder was an American jet attack aircraft of the Cold War and the modern era. The aircraft first flew in 1960 and entered service in 1963. A total of about 690 aircraft of this type were built. In the A-6 E version, the propulsion was provided by two Pratt and Whitney J-52-P8B engines, each with a thrust of 41 kN. The machine did not have a permanent on-board armament. However, it could carry a load of bombs and rockets with a total weight of up to 8,200 kg.
The Grumman A-6 Intruder was developed as the successor to the piston-engined A-1 Skyraider aircraft. The US Navy described the new machine as capable of operating in all weather conditions as well as being powered by a jet engine. It is also worth adding that the aircraft was designed primarily for low and medium altitude flights and for flights at subsonic speeds. Finally, a successful machine was created, which performed well, among other things, during the Vietnam War (1964 / 1965-1975) and the First Gulf War (1990-1991). Several versions of this aircraft were created, such as: A-6A (the first mass-produced version), A-6C (version adapted for operation at night) or A-6E (the last version of the aircraft dedicated to attack tasks, with a decidedly modernized avionics). It is worth noting that the EA-6B Prowler electronic warfare aircraft was also developed based on the A-6. A-6 aircraft were not exported.
