In addition, as was noted above, the United States could use a hypersonic glide vehicle, like the CAV under consideration in the Falcon Study, as the reentry body on a long-range ballistic missile.
It also allotted $30 million in FY2008 and $40 million in FY2009 for alternative reentry systems development, a reference to the Medium-Lift Reentry Body that could be deployed on a new sea-based ballistic missile.
(98) Further, their deployment with a hypersonic reentry body, rather than a standard post-boost vehicle and warhead present on a nuclear-armed missile, would reinforce this designation.
Nevertheless, Navy officials have stated that there would be "immediate observable differences at launch" between this missile and a Trident missile because this missile would use two, rather than three, stages and would deliver a single reentry body and warhead, while the Trident missiles can carry up to eight warheads.
(30) According to the Defense Science Board Task Force on Future Strategic Strike Forces, the IMU would guide the missile in its early phases, but the reentry body would receive a GPS update during its exoatmospheric flight; it would then use the IMU and control flaps to steer the warhead with GPS-like accuracy during atmospheric reentry.
