ASNA developed the 136 ft Do ringsail for the recovery of a 20,000 lb propulsion module for the Boeing EELV. The 136 ft parachutes were based on the ASNA designed 85.6 ft F-111 crew escape module parachutes.  The parachutes were tested in the single canopy and in the 3-parachute cluster configuration.  The canopies exhibited excellent performance in terms of managing opening loads, load share, drag coefficient, and stability.

Demonstration tests off the coast of NASA Stennis demonstrated suitable performance for recovering a space shuttle main engine.
