Design and development

Dedicated high altitude photo-reconnaissance development of the Yak-25 fighter was named Yak-27R (NATO designation 'Mangrove'). It had replaced the radar and radome of the fighter with a glazed nose for an observer/navigator but retained the starboard Nudelman-Rikhter NR-23 cannon. 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 Tumansky RD-9AF turbojet engines 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.

Interceptor variant equipped with a supplemental rocket engine (named Yak-27V) was designed. During flight tests reached 23,000 m (75,400 ft) but did not enter service.

Yak-27R entered service in 1960 and was retired in late 1970s.
