Frank Kelly, deputy assistant secretary of the Navy for unmanned systems, checks out a Bell 206 helicopter equipped with the Office of Naval Research-funded Autonomous Aerial Cargo/Utility System (AACUS) sensor suite, following integrated flight testing at the Flying Circus Aerodrome located in Bealeton, Virginia.
