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).
Mikoyan-Gurevich MiG-15 The Mikoyan-Gurevich MiG-15 (Russian: Микоян и Гуревич МиГ-15 ; USAF/DoD designation: Type 14; NATO reporting name: Fagot) was a jet fighter aircraft developed by Mikoyan-Gurevich for the Soviet Union. The MiG-15 was one of the first successful jet fighters to incorporate swept wings to achieve high transonic speeds. In combat over Korea, it outclassed straight-winged jet day fighters, which were largely relegated to ground-attack roles, and was quickly countered by the similar American swept-wing North American F-86 Sabre. The MiG-15 is often mentioned, along with the F-86 Sabre, as the best fighter aircraft of the Korean War.
