The DP-4 is an early rotary wing Unmanned Aerial Vehicle (UAV) produced in 1992. It was designed to be operated by a two-man team as an autonomous system that could provide tactical reconnaissance, surveillance, and targeting information to small forward deployed units of the U.S. miltary.
The aircraft’s endurance was two hours and its approximate cost was $135,000.
Dragonfly Pictures of Essington, PA continues to develop UAV’s for military and commercial applications. It was founded by Michael Piasecki, son of helicopter pioneer Frank Piasecki.
