The DRS Sentry HP is a reconnaissance UAV that was developed in the United States in the late 1980s by S-TEC. The program was acquired by Meggitt in 2000 and subsequently by DRS in 2002. Although the aircraft shares the name "Sentry" with a previous S-TEC design, the Sentry HP is a completely different machine, with a broad wing and a V tail. The Sentry HP is larger, with greater payload capacity and an underwing stores capability. It is powered by a variant of the same engine as the Sentry. It can be ordered with an option for fixed landing gear to permit conventional takeoff and recovery.
