The WAC Corporal was the United States first sounding rocket. Seventeen Wac and Wac B rockets were flown from 1945 to 1947. The WAC was launched with the aid of the Tiny Tim solid propellant booster. After the booster burned out, it fell away and the liquid fuel propelled sustainer stage continued its' upward flight.

This model of the upper stage of America's first Sounding Rocket is easy to build and flies well on A through C motors - perfect for any size field!
One of our original kits, this model has been updated with laser-cut fins, quick-change engine hook and re-written instructions!
