Lockheed Martin SR-72 Lockheed Martin SR-72 The Lockheed Martin SR-72 is an American hypersonic UAV concept intended for intelligence, surveillance and reconnaissance. Lockheed Martin privately proposed it to succeed the retired Lockheed SR-71 Blackbird. The SR-71 Blackbird retired in 1998, leaving what was considered a coverage gap between surveillance satellites, manned aircraft, and unmanned aerial vehicles for intelligence, surveillance and reconnaissance (ISR) and strike missions. With the growth of anti-satellite weapons, anti-access/area denial tactics, and counter-stealth technologies, a high-speed aircraft could penetrate protected airspace and observe or strike a target before enemies could detect or intercept it. The proposed reliance on extremely high
Lockheed Martin A2100 Lockheed Martin A2100 The A2100 is a communications satellite spacecraft model made by Lockheed Martin Space Systems in the 1990s-2010s for telecommunications in geosynchronous orbit, as well as GOES-R weather satellites and GPS Block IIIA satellites. The Lockheed Martin A2100 geosynchronous spacecraft series is designed for a variety of telecommunications needs including K band broadband and broadcast services, fixed satellite services in C-band and K band payload configurations, high-power direct broadcast services using the K band frequency spectrum, and mobile satellite services using UHF, L-band and S-band payloads. The A2100 satellite system was developed by a Skunk Works team at
