SkyR J348B

Engineered by Sky Ripper Systems, the J348B is a 54mm solid rocket motor designed for high-power rocketry (HPR). As an official J-class motor, it delivers a total impulse of 716.0 Ns over a 2.20 second burn window.

With an average thrust of 324.0 N and a peak of 1553.0 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the ABS/B, 550cc nitrous propellant formulation, dictating its specific impulse and exhaust signature.
