The AAI RQ-2 Pioneer is an unmanned aerial vehicle (UAV) that was used by the United States Navy, Marine Corps, and Army, and deployed at sea and on land from 1986 until 2007.

It flies day or night missions with a gimbaled EO/IR sensor, relaying analog video in real time via a C-band line-of-sight (LOS) data link.

Since 1991, Pioneer has flown reconnaissance missions during the Persian Gulf, Somalia (UNOSOM II), Bosnia, Kosovo and Iraq conflicts.

When navy officials offered to transfer a Pioneer to the Smithsonian Institution, curators at the National Air and Space Museum specifically asked for the UAV that Iraqi troops surrendered to during the Gulf War.

The UAV Platoon conducted flight surveillance and target acquisition missions from KKMC and later, the unit pushed north (Operation Sand Hawk) where US Army combat engineers built a metal runway for the aircraft to launch and recover.
