I just had my resume submitted by a shop to ATK, which manufactures thing related to rockets, drones, and small arms, and then I came across the fact that they got a contract for a target drone to simulate the SS-N-27 Sizzler (Novator 34M-54E Klub).
It’s an interesting concept. It’s a two stage cruise missile proceeding at subsonic speeds for most of its flight path, but about 20-30 miles from the target, the second stages fires and it accelerates to somewhere around mach 2.9 for the final flight to target.
You end up with a supersonic approach just as it goes over the horizon, but the total package is much smaller, or the range is much greater, than something that would be supersonic along the complete flight path.
ATK’s job may actually be more difficult than making the weapon, as one would assume that you would want the possibility of recovery for the drone, at least when the defenders get it wrong in practice.
It’s called the Multi-Stage Supersonic Target (MSST).
Basically, you have a subsonic bus which carries the whole assembly, and the supersonic portion, based on the GQM-163 Coyote supersonic target drone is hung from a strongback.
Full disclosure: They have my resume in their hands right now, at least that’s what the shop told me.
