The DRS Sentry HP is a reconnaissance UAV that was developed in the United States in the late 1980s by S-TEC.

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 can be ordered with an option for fixed landing gear to permit conventional takeoff and recovery.
