Yakovlev Yak-28 (NATO reporting name: "Firebar")
The Yakovlev Yak-28 (Russian: Яковлев Як-28) is a swept wing, turbojet-powered combat aircraft used by the Soviet Union. Produced initially as a tactical medium bomber, it was also manufactured in reconnaissance, electronic warfare, interceptor, and trainer versions, known by the NATO reporting names Brewer, Brewer-E, Firebar, and Maestro respectively. Based on the Yak-129 prototype first flown on 5 March 1958, it began to enter service in 1960.
Design and development
Origins
The Yak-28 was first seen by the West at the Tushino air show in 1961. Western analysts initially believed it to be a fighter rather than an attack aircraft—and a continuation of the Yak-25M—and it was designated "Flashlight". After its actual role was realized, the Yak-28 bomber series was redesignated "Brewer
Yakovlev Yak-28U A single Yak-28 converted for testing short takeoff and landing techniques with JATO bottles and braking parachutes.
Yak-28SR prototype (samolyot raspylitel – spraying/dusting aircraft) first use of SR.
Chemical warfare aircraft for dispensing dust or liquid agents from underwing tank/applicators. Though recommended for production none were delivered to the VVS.

Upgraded Yak-28P with R11AF3-300 engines, flight testing started in 1963 but development abandoned when the R11AF3-300 did not enter production.The re-engined "PM" modification has established a speed record of 2,400 km/h in 1963.
Yak-28URP prototype
High altitude interceptor prototype using a rocket engine to boost performance during the interception phase.
The aircraft is perhaps best known for the heroic actions of Captain Boris Kapustin and Lieutenant Yuri Yanov after the Yak-28 they were piloting suffered a catastrophic engine malfunction on 6 April 1966. They were ordered to divert to attempt a landing in Soviet zone of Germany, but lost control of the aircraft and strayed into the airspace of West Berlin.
