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.

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world's fastest jet-propelled aircraft. The Blackbird's performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War.

2020年7月20日 · The Lockheed SR-71, designed in secrecy in the late 1950s, was able to cruise near the edge of space and outfly a missile. To this day, it holds the records for the highest...

2012年7月20日 · Faster than a speeding bullet, the retired SR-71 Blackbird can still turn heads as a Cold War spy plane designed for flying high and fast beyond danger. The ultimate flying speed demon not only...

Throughout its nearly 24-year career, the SR-71 remained the world's fastest and highest-flying operational aircraft. From 80,000 feet, it could survey 100,000 square miles of Earth's surface per hour.

2016年7月28日 · In 1976, the Lockheed SR-71 Blackbird broke the world’s record for sustained altitude in horizontal flight at 25,929 meters (85,069 feet). The same day another SR-71 set an absolute speed record of 3,529.6 kilometers per hour …

The SR-71, created by Lockheed engineer Kelly Johnson, was a Cold War-era stalward, flying higher and faster than Soviet air defenses could reach, making it a critical component of United States Air Force and CIA operations for decades before a reliance on advanced satellite technologies forced her into retirement.

Designed over half a century ago, the SR-71 still holds records as the fastest and highest-flying crewed aircraft. The design pioneered stealth technology. The plane is one of the most distinctive and storied chapters in aviation history. In the late 1950s and early 1960s, the Cold war between the Soviet Union and the United States was heating up.

The Lockheed SR-71 Blackbird is the fastest and highest-flying jet aircraft in history and Duxford’s SR-71 Blackbird has flown higher than any other when it set the world record for sustained altitude flight in 1976, flying at 85,000 feet.

The Lockheed SR-71 Blackbird was a two-seat twin-engine long-range supersonic strategic reconnaissance aircraft produced by Lockheed Corporation. The SR-71 was capable of flying at speeds over Mach 3.2 and at a height of 85,000 feet (25,900 Meter). The SR-71 was in duty from 1964 until 1989 and during a reactivation from 1993 until 1998.
