Yakovlev Yak-27

From Wikipedia, the free encyclopedia

The Yakovlev Yak-27 was a high-altitude derivative of the Yak-25 (NATO reporting name 'Flashlight'), developed in 1958 as the Yak-122 prototype.

Two versions were developed:

• Yak-27V: interceptor with a supplemental rocket engine. Did not enter service (although a flight test reached 23,000 m (75,400 ft)).
• Yak-27R (NATO designation 'Mangrove'): dedicated photo-reconnaissance version. Replaced the radar and radome of the fighter with a glazed nose for an observer/navigator. It retained the starboard Nudelman NL-37 cannon, but the port gun was deleted and two recce cameras were added. It had a longer wing with a span of 11.82 m (38 ft 9 in), with two Tumanskii RD-9AF turbojets, and had a top speed of about 1,285 km/h (798 mph) at high altitude, with a service ceiling of 16,500 m (54,000 ft) and a range of 2,380 km (1,480 mi) with two wing tanks. About 180 were produced, entering service in 1960.
