The
Mikoyan MiG-27 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 with the Kazakh and Sri Lankan Air Forces in the ground attack role. All Russian, Indian and Ukrainian MiG-27s have been retired.
