 DARPA conducted a series of "paper studies" and workshops on the concept in 1995 and 1996, leading to early engineering studies by the Lincoln Laboratories at the Massachusetts Institute of Technology (MIT), and the US Naval Research Laboratory (NRL) in Washington, D.C.The studies demonstrated that the concept was feasible.In 1997, DARPA then began a multi-year, US$35 million development program to develop "micro air vehicles (MAVs)".
