prior to first stage ignition. The post boost vehicle consists of a structure to house the guidance and solid propulsion systems and a platform to mount the reentry vehicles. The post boost vehicle provides the reentry vehicle spacing and deployment maneuvers. The basic dimensions, length, and diameter, were derived from submarine launcher volumetric constraints. The booster stages were sized to provide for Navy guidance access requirements at the II-III interstage and for at-sea maintenance access. The missile was designed to fill the current Trident submarine tube.
