General Atomics has recently conducted a flight demonstration of two Avenger unmanned aircraft systems (UAS), each equipped with Lockheed Martin’s Legion Pod IRST21, an Infra-Red Search & Track pod designed to detect aerial targets at long range, without using radar.  This capability brings drones one step closer to having autonomous systems that support manned-unmanned teaming (MUM-T) in joint all-domain operations. https://defense-update.com/20220111_irst-for-drones.html
