Boeing recently returned the first production A160T Hummingbird unmanned rotorcraft, A020, to the assembly line after applying the aircraft’s final, light-gray coat of paint. The A160T is shown entering the paint hangar in this photo. Last week, Boeing submitted a bid that offers the world record-holding A160T in response to the Naval Air Systems Command’s Request for Proposal for Cargo Unmanned Aircraft Systems Services. Boeing is building the Hummingbird at its facility in Mesa and expects to complete A020 by the end of this year.
