Rocksanne I-X was the firts rocket designed, projected and realized by Skyward. It is a low target and simple rocket with a specific attention to reusability.

Realizing the rocket needed one and a half year, and it took its first flight in November 2013, with prohibitive weather conditions, strong wind and snow. Rocksanne I-X v.2013 flew more than 900m high with 6g peak acceleration.

Parachute deployment re-designed to stand higher shocks and allow softer landing to all sub-systems

Rocksanne I-X CT  is a lighter revision of RI-X, with carbon fiber fincan and fins and a re-designed recovery system to be more reliable and more resistant to high shock.

It took its first flight in June 2014 and it was launched twice in less than 24 hours, being able to soft land intact close to the launch site, ready to be reused.
