Mikoyan MiG-27

https://en.wikipedia.org/wiki/Mikoyan_MiG-27

The Mikoyan MiG-27 (Russian: ?????? ???-27; NATO reporting name: Flogger-D/J) is
a variable-geometry ground-attack aircraft, originally built by the
Mikoyan-Gurevich design bureau in the Soviet Union and later licence-produced in
India by Hindustan Aeronautics as the Bahadur ("Valiant"). It is based on the
Mikoyan-Gurevich MiG-23 fighter aircraft, but optimised for air-to-ground
attack. Unlike the MiG-23, the MiG-27 did not have widespread use outside
Russia, as most countries opted for the Mikoyan-Gurevich MiG-23BN and Sukhoi
Su-22 instead. It remains in service only with the Kazakh Air Forces in the
ground attack role. All Russian, Indian and Ukrainian MiG-27s have been retired.

The MiG-27 shares the basic airframe of the MiG-23, but with a revised nose –
nicknamed "Utkonos" ("Platypus") in Russian service, first introduced on the
MiG-23B. Dissatisfaction with the MiG-23BN led to the further development of the
basic airframe to accommodate a stronger undercarriage, simpler intakes and a
shorter exhaust nozzle, without radar in favor of a downward-sloping profile for
improved pilot visibility, a laser rangefinder and marked-target seeker.[4]
Among its test pilots, it was also called "Balkon" ("Balcony") because of the
increased frontal view from the cockpit. Additional cockpit armor was installed,
along with a totally new nav/attack system.

Since the MiG-27 was intended to fly most of its missions at low altitude, the
MiG-23's variable intake ramps and exhaust nozzles were discarded in favor of a
simpler fixed configuration, reducing weight and maintenance requirements. The
aircraft also has larger, heavy-duty landing gear to facilitate operation from
poorer-quality airfields. In accordance with the MiG-27's strike and low-level
attack requirements, provisions were made to mount missiles and precision-guided
munitions, as well as retaining a nuclear capability in line with other Soviet
combat aircraft by introducing specialized navigation systems.

Soviet forces used the MiG-27 during the later stages of the Afghanistan
conflict in 1987–89.

Although several Western observers considered the MiG-27 widely exported,
confusing it with the MiG-23BN, the aircraft type was only exported to India and
Sri Lanka which also utilized the MiG-27 in regional conflicts.

12 MiG-27 remains in service with the Kazakh Air Force.
