 The Navy has envisioned using pogo UCAVs to arm a guided-missile destroyer "unmanned air wing" with 20 pogo UCAVs for strike, and five pogo UAVs for reconnaissance.The submarine launch concept was even more speculative, since recovery was a problem.The Lockheed Martin UCAV concepts were in the 4.5 tonne (10,000 pound) weight class and carried a warload of 450 kilograms (1,000 pounds).
