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 Lunar Lander are a variant of the RL10 that uses the bi-propellant liquid oxygen / liquid hydrogen, generating an estimated impulse (delta-v) of 5 km/s. Lockheed Martin Lunar Lander The Lockheed Martin Lunar Lander (or Mars-Precursor Lunar Lander) is a design concept by Lockheed Martin of a reusable crewed lunar lander that could take astronauts from the Lunar Orbital Platform-Gateway —a proposed habitat that NASA plans to build in orbit around the Moon— to the lunar surface and advance technology needed to explore Mars. The reusable lander would enable sustainable lunar surface exploration. The design concept was unveiled in October 2018, and
