The Lockheed Martin SR-72, commonly referred to as "Son of Blackbird," is an American hypersonic concept intended for intelligence, surveillance, and reconnaissance (ISR). Proposed privately in 2013 by Lockheed Martin as a successor to the retired Lockheed SR-71 Blackbird, the SR-72 was projected by Lockheed Martin executives in 2018 to have a test vehicle fly by 2025 and potentially enter service in the 2030s.
