Limited by a top speed of Mach 2.1 and a service ceiling of 18 kilometres (11 mi), the Viggen pilots would line up for a frontal attack, and rely on their state-of-the-art avionics to climb at the right time and attain a missile lock on the SR-71.
The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [1] which also ratifies any claims. Speed records ...
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
JP-7 was developed for the Pratt & Whitney J58 (JT11D-20) turbojet engine, which was used primarily in the Lockheed SR-71 Blackbird which retired in 1999. The SR-71 design speed was Mach 3.2 at which very high skin temperatures occurred due to aerodynamic heating.
The SR-71 Blackbird successor is a step closer to breaking the airspeed record. Quarterhorse, the Air Force's next hypersonic aircraft, has taken an epic leap. The SR-71 Blackbird successor is a ...

Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some fighter jets are capable of supercruise but only at high altitudes and in a clean configuration, so the term may imply "a significant increase in effective combat speed with a full weapons load over existing types".

It set and held speed and altitude world records of over 2,000 miles per hour (3,200 km/h) and over 80,000 feet (24,000 m) (later surpassed by the closely related SR-71 Blackbird), and is the world's largest, heaviest and fastest crewed interceptor. [1]
