Eventhough it was not produced in large numbers it contributed alot to the Soviet/Russian aviation. The first prototype designed as an all-weather two seater made its first flight in 1952. With swept wings and two wing-mounted jet engines they were able to patrol for 2.5 hours. They had a very primitive radar weighing half a ton at the nose. Yak-25 was preferred by the pilots since it was an easy-to-learn and easy-to-fly plane. There are advanced models such Yak-25B which had an aimer’s glass nose instead of the radar, Yak-25K-75 which was capable of carrying 2 to 4 AA-1 “Atoll” AA guided missiles , interceptor-fighter version Yak-25K-8 (NATO code name:Flashlight), Yak-25R with nose mounted cameras and Yak-25RV(NATO code name:Mandrake) tactical recconnaissance types. Yak-125 is the high altitude model with extended wings. Yak-25 planes were used as testbeds for air-intakes and for ejection seats.Yak-25 entered service in 1955, and Yak-25RV in 1959.
