The Tu-22M was developed from the earlier Tu-22 design, incorporating variable-geometry outer wing panels. The first Tu-22M-0 prototype flew in 1969. Powered by a military derivative of the engine originally designed for the Tu-144 supersonic airliner, the Backfire is extremely fast, even at low level. The Tu-22M lacks sufficient range for truly strategic missions and is classified as a medium-range bomber.
The first series production model was the Tu-22M-2 Backfire-B (211 built) for the Soviet Air Forces and the Naval Aviation Forces. Normally armed with a single Kh-22 stand-off missile, this variant became operational with 185 Guard Heavy Bomber Aviation Regiment at Poltava in 1978, and also served during the Soviet War in Afghanistan.
The ultimate bomber/missile carrying variant is the Tu-22M-3 Backfire-C, (268 built). The M-3 features strengthened wings, raked rectangular intakes serving more powerful engines. It also had a greatly increased weapons load (see specification). The Tu-22M3 remains numerically the most important bomber in the Russian air force's Long-Range Air Army inventory, and serves with seven regiments (one of which also operates Tu-22M-2s). The Naval Aviation Forces have about 80 Tu-22Ms, mostly M-3 models, split equally between divisions subordinated to the Northern and Pacific Fleets. The Naval Aviation Forces also have 12 M-3s converted as Tu-22MR reconnaissance aircraft, and reportedly also operates limited numbers of recce-configured Tu-22M2Rs.
