NK84

NK84 is a designation that can refer to several different entities, most notably a Soviet-era reconnaissance aircraft and a specific type of rocket.

The NK84 is a twin-engine, swept-wing reconnaissance aircraft developed by the Soviet Union. It was designed for high-altitude photographic and electronic intelligence gathering missions. While specific details about its operational deployment are limited, it is believed to have been part of the Soviet Air Force's reconnaissance capabilities during the latter part of the Cold War. Its design emphasized speed and altitude to evade enemy defenses.

In a different context, NK84 also refers to a Soviet liquid-propellant rocket engine. This engine was designed for use in various launch vehicles and missile systems. It was known for its relatively high thrust and reliability. Like the aircraft, detailed technical specifications and operational history for the NK84 rocket engine are not widely disseminated. The designation NK typically denotes engines developed by the Kuznetsov Design Bureau.
