The Yakovlev Yak-28 (Russian: Яковлев Як-28) is a swept-wing, turbojet-powered combat aircraft developed and operated by the Soviet Union. Initially designed as a tactical medium bomber, it was later adapted into several specialized roles including reconnaissance, electronic warfare, interception, and training. These variants were identified by NATO with the reporting names Brewer, Brewer-E, Firebar, and Maestro, respectively. Originating from the Yak-129 prototype that first took flight on March 5, 1958, the Yak-28 entered operational service in 1964.
Design and development
Western observers first encountered the Yak-28 at the Tushino air show in 1961. Early Western assessments mistakenly categorized it as a fighter aircraft and presumed it to be a development of the Yak-25M, assigning it the codename "Flashlight". Once its true function as a bomber was identified, the designation was revised to "Brewer".
The aircraft featured a prominent mid-wing with a sweep angle of 45 degrees. Its horizontal stabilizer was mounted midway up the vertical fin, which included cutouts to enable rudder deflection. Leading-edge slats and trailing-edge slotted flaps enhanced its aerodynamic control surfaces. Powered by two Tumansky R-11 turbojets—each initially delivering 57 kN (12,795 lbf) of thrust—the engines were housed in pods mounted on the wings, similar to the arrangement on the earlier Yak-25. The landing gear employed a bicycle configuration with widely spaced main wheels under the fuselage and auxiliary outrigger wheels enclosed within fairings near the wingtips. This layout freed substantial fuselage space for fuel storage and onboard systems. Although primarily operating below supersonic speeds, it was capable of exceeding Mach 1 at higher altitudes.
Production across all Yak-28 models totaled approximately 1,180 units.
Operational history
One of the most notable incidents involving this aircraft occurred on April 6, 1966, when Captain Boris Kapustin and Lieutenant Yuri Yanov piloted a Yak-28 that experienced a severe engine failure. Directed to divert for an emergency landing within Soviet-controlled Germany, they lost control and inadvertently entered West Berlin airspace. Demonstrating exceptional skill, the crew avoided crashing into residential areas but ultimately went down in Lake Stößensee [de] without ejecting. Recovery operations were conducted by Royal Navy divers dispatched from Portsmouth alongside salvage teams who retrieved critical classified materials from the wreckage. The engines were transported to RAF Gatow where British and American engineers examined them thoroughly. Both pilots received military honors from Soviet and British forces posthumously and were awarded the Order of the Red Banner. The first engine was salvaged on April 18, followed by the second about a week later; both were returned to Soviet authorities on May 2, 1966.
The Yak-28P interceptor variant was phased out during the early 1980s; however, trainer and other specialized versions continued service beyond the dissolution of the Soviet Union, remaining active until at least 1992. Reconnaissance and electronic countermeasure models were eventually superseded by derivatives of the Sukhoi Su-24.
Prototype
Yak-129
Served as the initial prototype for the Yak-28.[1]
Yak-28SR prototype (samolyot raspylitel – spraying/dusting aircraft) marked the initial application of the SR designation.[1]
Designed as a chemical warfare platform, this variant was intended to disperse dust or liquid substances via underwing tanks and applicators. Despite recommendations for mass production, none were delivered to the VVS.
An enhanced Yak-28P featuring R11AF3-300 engines; flight tests commenced in 1963 but development ceased when the R11AF3-300 engines were not mass-produced. The "PM" version set a speed record of 2,400 km/h during 1963.
Yak-28URP prototype
A high-altitude interceptor concept incorporating a rocket engine to augment performance during interception missions.
Yak-28-64 prototype
This extensively reworked Yak-28P variant had Tumansky R-11F2-300 engines relocated to the rear fuselage with extended intakes reaching near the cockpit, aiming to rival the Sukhoi Su-15. Performance fell short expectations, being slower than the Yak-28P, and critical aileron reversal problems led to its discontinuation.
A conceptual vertical takeoff and landing aircraft featuring two R-27AF-300 lift/cruise engines and four R39P-300 lift engines housed in the forward fuselage.
The inaugural tactical bombing training aircraft produced. Since radar and avionics were incomplete, it was primarily intended for daytime use. It mainly served as a transition trainer for crews adapting to new aircraft types and as ground-based instructional material. Subsequent mass-produced variants incorporated some of its wiring layouts and components.[1]
Yak-28B (Izdeliye 28B; NATO reporting name: "Brewer-A")
The production model of the Yak-28 equipped with weapon aiming radar and various enhancements including fittings for JATO bottles. The total quantity produced remains unspecified.[2]
Yak-28L (Izdeliye 28L; NATO reporting name: "Brewer-B")
A tactical bomber integrating a ground-controlled targeting system based on triangulation from land transmitters. A total of 111 units were manufactured.[2]
Yak-28I (Izdeliye 28I; NATO reporting name: "Brewer-C")
A tactical bomber fitted with the "Initsiativa-2" internal targeting system featuring 360-degree ground-mapping radar capabilities. Production reached 223 aircraft.[2]
Designed as a dual-control trainer with an additional cockpit positioned in the nose for student pilots; first built as a prototype in 1962.[2] A total of 183 were completed.[2]
Yak-28R (Izdeliye 28R; NATO reporting name: "Brewer-D")
A specialized tactical reconnaissance variant derived from the Yak-28I, featuring increased canopy headroom for the pilot, expanded nose glazing with an angled rear bulkhead, Initsiativa-2 radar, and five interchangeable pallets outfitted with various mission equipment. Prototype flew in 1963.[2] A total of 183 units were produced.[2]
Yak-28SR (Izdeliye 28SR) representing a second use of SR.[1]
A tactical reconnaissance model equipped with an active radio/radar jammer system (either SPS-141 or SPS-143). Manufactured in limited numbers.
A television reconnaissance platform designed to transmit live imagery to ground stations. It included a backup still camera with a focal length of 190 mm.
Yak-28RR (Izdeliye 28RR)
A radiation intelligence aircraft fitted with RR8311-100 air sampling pods for collecting nuclear test samples. These pods were specifically developed for the Yak-28RR but later became standard on all subsequent radiation reconnaissance platforms. Converted from existing Yak-28R airframes.[2]
Yak-28RL
A radiation intelligence variant equipped solely with RR8311-100 air sampling pods without additional specialized equipment. Modified from several existing Yak-28L aircraft.[2]File:Yakovlev Yak-28R and Yak-28PP side-view silhouettes.pngYakovlev Yak-28R and Yak-28PP
Yak-28PP (Izeliye 28PP) (NATO reporting name – "Brewer-E")
Introduced in 1970 as the Soviet Union's first dedicated electronic countermeasures (ECM) platform.[3] This unarmed aircraft housed an extensive electronic warfare (EW) suite within its bomb bay,[3] complemented by multiple antennas and dielectric panels used to emit jamming signals. Heat generated by this equipment was managed through heat exchangers located beneath the center fuselage; notably, it lacked a radome.[3] Production quantities during the 1970s remain unknown.[2]
Yak-28P (Izdeliye 40) (NATO reporting name – "Firebar")
A purpose-built long-range interceptor, development began in 1960 with operational deployment starting in 1964.[2] This version eliminated the internal weapons bay to accommodate additional fuselage fuel tanks, resulting in substantial fuel capacity limited primarily by weight constraints rather than volume. It employed an upgraded Oriol-D' interception radar compatible with the R-98 (AA-3 'Anab') air-to-air missile. Later production models featured an extended conical radome and enhanced armament systems. Production continued until 1967, totaling 435 units built.[2]
