The first unconfirmed reports about the SR-72 emerged in 2007, when various sources reported that Lockheed Martin's Advanced Development Programs (ADP) division, Skunk Works, was developing an aircraft capable of flying at six times the speed of sound, or Mach 6 (4,000 mph; 6,400 km/h; 3,500 kn), for the United States Air Force—about twice as ...

2014年1月30日 · The SR-72 aircraft will have the capability to perform high speed intelligence, surveillance and reconnaissance (ISR) and strike operations. The first flight of the SR-72 demonstrator is anticipated in 2023, while the full scale aircraft is …

What is the top speed of the SR-72, and how does it achieve it? The SR-72 is designed to reach speeds of up to Mach 6, thanks to its turbine-based combined cycle (TBCC) engine. This engine integrates conventional jet propulsion for takeoff and a scramjet engine for hypersonic flight.

2019年5月9日 · The aircraft was conceived as an unmanned system which would not risk pilots to the extreme conditions and dangers expected of its super high-speed/high-altitude flight with the SR-72 estimated to reach speeds around Mach 6.

The Lockheed Martin SR-72 is a conceptualized unmanned, hypersonic aircraft intended for intelligence, surveillance and reconnaissance proposed by Lockheed Martin to succeed the retired SR-71 Blackbird.

2025年3月12日 · It achieved a maximum speed of Mach 20 (~20,900 kilometers per hour). The knowledge and data obtained from the HTV-2 are now being used to develop better designs for the SR-72.

2025年2月8日 · The SR-72 Darkstar, developed by Lockheed Martin's Skunk Works, is poised to become the fastest aircraft in history, reaching a staggering Mach 6 (4,000 mph or 6,400 km/h). Designed for hypersonic reconnaissance and strike missions, the Darkstar is expected to outclass the legendary SR-71 Blackbird.

2024年1月2日 · Believed to be a top-secret project for the United States Air Force (USAF), the SR-72 is touted to reach over 4,000 mph (6,437 kph), making it the fastest plane ever developed.

2025年2月27日 · Its maximum speed is more on the order of Mach 6.0. That’s roughly 4600 mph or almost double the speed rating for the SR-71. Besides the aircraft’s speed, it is also supposedly designed—like the SR-71—to operate at altitudes exceeding 80,000 feet and have an operational range of over 3000 miles.

2024年10月27日 · Building upon the legacy of its predecessor, the SR-72 aims to push the boundaries even further, reaching unprecedented speeds and offering unparalleled capabilities. Unveiling the SR-72's Top Speed. At the heart of the SR-72's allure is its astounding top speed, which is projected to exceed Mach 6, or approximately 4,500 miles per hour.
