The EWS/RROCI 12U SUPERNOVA bus incorporates several unique Pumpkin subsystems, including the articulated 132W DASA array, the EPSM 1 multi-channel power system and two BM 2 intelligent batteries. "At each and every point in the environmental test campaign of this Pumpkin 12U SUPERNOVA bus, TVAC and/or vibe testing identified  zero issues surrounding Pumpkin components and subsystems," said Dr. Andrew Kalman, Pumpkin's President & CTO. "We're very pleased to support the Space Force's mission with this highly capable Pumpkin bus."
