Stinger will go on. Gets a modern engine

In the United States, work is being carried out to radically increase the scope of Stinger missiles, and in the future besides another missiles. The thought is to introduce a two-stage stream engine alternatively of a classical solid fuel drive**. The fresh drive is designed to combine the components of a standard rocket engine, utilized as a launcher for speeding the projectile to supersonic speed, with a stream drive that is activated after reaching supersonic velocity and firing the starter's fuel. Then the air inlet, essential for the operation of the stream drive, placed in the front of the projectile, opens. The usage of stream drive importantly increases the scope of the missile's flight, which may have a crucial impact on Stinger's abilities.
