The US Defense Advanced Research Projects Agency (DARPA) is one step closer to demonstrating the launch and recovery of a medium-sized unmanned air vehicle (UAV) from a small vessel, following a $19 million preliminary design contract award to AeroVironment.
Under phase II of DARPA’s tactically exploited reconnaissance node (Tern) programme, the company will conduct “subscale flight demonstrations” over the next 12 months that will subsequently lead on to a sole-source phase III at-sea demonstration contract award.
DARPA launched the TERN effort in 2013, but joined with the US Navy’s Office of Naval Research (ONR) in May 2014 to continue the programme, which was retitled “Tern”.
The agency considers assets that provide worldwide airborne intelligence, surveillance and reconnaissance (ISR) as having weaknesses – specifically helicopters being limited by range and flight time, and manned and unmanned fixed-wing aircraft being restricted by large base and runway requirements.
“Tern envisions using smaller ships as mobile launch and recovery sites for medium-altitude long-endurance [MALE] unmanned aircraft,” DARPA says. “Ideally, Tern would enable on-demand, ship-based unmanned aircraft system operations without extensive, time-consuming and irreversible ship modifications.”
