The Pratt & Whitney J58 was a jet engine that powered a long-range, Mach 3+ strategic reconnaissance aircraft operated by who?
Pratt &amp; Whitney J58 The Pratt & Whitney J58 (company designation JT11D-20) was a jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. The J58 was a single-spool turbojet with an afterburner. It had a unique bleed from the compressor to the afterburner which gave increased thrust at high speeds. This feature caused it to be referred to as a turboramjet in some writings. It delivered 25,000 pound-force (110 kN) of thrust without afterburner (dry) and 34,000 (150 kN) with afterburner (wet).
Hawker Tempest The Hawker Tempest is a British fighter aircraft primarily used by the Royal Air Force (RAF) in the Second World War. The Tempest, originally known as the "Typhoon II", was an improved derivative of the Hawker Typhoon, intended to address the Typhoon's unexpected fall-off of performance at high altitude by replacing its wing with a thinner laminar flow design. Having diverged considerably from the Typhoon, it was chosen to rename the aircraft "Tempest". The Tempest emerged as one of the most powerful fighters of World War II and was the fastest single-engine propeller-driven aircraft of the war at low altitude. The propeller-driven Dornier 335 was even faster, but it had two engines.
