Seeking to combine the strengths of both land and sea-based approaches to supporting airborne assets, DARPA has launched the Tactically Exploited Reconnaissance Node (TERN) program, which envisions to use smaller ships as mobile launch and recovery sites for medium-altitude long-endurance (MALE) fixed-wing unmanned aircraft (UAVs). Named after the family of seabirds known for flight endurance – many species migrate thousands of miles each year – TERN aims to make it much easier, quicker and less expensive for U.S Dept of Defence to deploy ISR and strike capabilities almost anywhere in the world.
“It’s like having a falcon return to the arm of any person equipped to receive it, instead ofto the same static perch every time,” said Daniel Patt, DARPA program manager. “About 98 percent of the world’s land area lies within 900 nautical miles of ocean coastlines.Enabling small ships to launch and retrieve long-endurance UAVs on demand would greatly expand our situational awareness and our ability to quickly and flexibly engage in hotspots over land or water.”
The normal approach to operating a large aircraft from a small deck – a helicopter – won’t work, says DARPA, because their range and endurance is limited.
DARPA seeks proposals that would design, develop and demonstrate a MALE UAV and anassociated automated launch and recovery system.
The UAV would have to carry a 600-pound payload and have an operational radius of 600 to 900 nautical miles from its host vessel.
The launch and recovery system would have to fit U.S Navy Littoral Combat Ship 2 (LCS-2)-class ships and other surface combat vessels as feasible.
Key technical challenges include:
• Devising a reliable launch and recovery technique that enables large aircraft operations from smaller ships, even in rough seas;
• Designing an aircraft with range, endurance and payload comparable to emerging land-based unmanned aircraft, while still meeting the demands of the maritime environment;
• Ensuring the entire system can operate with minimal, and preferably reversible, ship modifications and minimal personnel requirements for operations and maintenance; and
• Packaging the system to fit into the limited space aboard ships.
DARPA plans to roll out TERN in three phases over approximately 40 months, culminating in a full-scale launch and recovery demonstration.
To familiarize potential participants with the technical objectives of TERN, DARPA will host a Proposers' Day on Tuesday, March 20, 2013, in the DARPA Conference Center.
