New propulsion program for legacy missile delivers a sharper sting
Red Wasp is an air defense interceptor S&T program at DEVCOM AvMC applying solid fuel ramjet tech to the Stinger missile to increase effective distance.

US is developing a new Stinger missile which will have considerably higher range and altitude compared to the standard FIM92 missile.
The new version will be powered by a solid fuelled Ramjet motor. It will have a booster section that will be discarded once the supersonic speed is achieved. Then the front of the missile will will give way to a port to allow airflow. By not having to store an oxidiser in the solid fuel tank, as this is supplied by the air the ramjet engine will breathe, more fuel will be available to increase speed and range.
By gaining thrust till the last second until impact, the missile will be deadlier and faster.
As a man pad, this new missile will be a game changer in terms of a short range air defence carried by individual soldiers.
