The Sukhoi Su-34 (Russian: ????? ??-34; NATO reporting name: Fullback)[7] is a Soviet-origin Russian twin-engine, twin-seat, all-weather supersonic medium-range fighter-bomber/strike aircraft.[8][9][10][11] It first flew in 1990, intended for the Soviet Air Forces, and it entered service in 2014 with the Russian Air Force.

Based on the Sukhoi Su-27 Flanker air superiority fighter, the Su-34 has an armoured cockpit with side-by-side seating for its two pilots.[13] The Su-34 was designed primarily for tactical deployment against ground and naval targets (tactical bombing/attack/interdiction roles, including against small and mobile targets) on solo and group missions in daytime and at night, under favourable and adverse weather conditions and in a hostile environment with counter-fire and electronic warfare (EW) counter-measures deployed, as well as for aerial reconnaissance.[8][14] The Su-34 is planned to eventually replace the Su-24 tactical bomber and the Tu-22M long-range bomber.

Design :

The Su-34 shares most of its wing structure, tail, and engine nacelles with the Su-27/Su-30, with canards like the Su-30MKI, Su-33 and Su-27M/35 to increase static instability (higher manoeuvrability) and to reduce trim drag.

The Su-34 is powered by a pair of Saturn AL-31FM1 turbofan engines, the same engines used on the Su-27SM, giving the aircraft a maximum speed of Mach 1.8+ when fully loaded.[64] Although slower than the standard Su-27, the Su-34 can still handle high G-loads and perform aerobatic maneuvers.[13] When equipped with a full weapons load, the Su-34 has a maximum range of 4,000 km (2,500 mi; 2,200 nmi), or further with aerial refueling.[65] The airframe is cleared to perform maneuvers of up to +9 g.[66] The noise level of the Su-34 is two times lower than the level of its predecessors.[67]

The Su-34 is a three lifting surface design having both a conventional horizontal tailplane at the rear and a canard foreplane in front of the main wings. The foreplane provides both additional lift (force) and greater maneuverability. It has twin tail fins like those of Su-27 from which it is derived. The Su-34 has 12 hardpoints for 12,000–14,000 kg (26,000–31,000 lb) of ordnance,[68] intended to include the latest Russian precision-guided weapons. It retains the 30 mm GSh-30-1 cannon of the Su-27 and Su-30,[69] and the ability to carry six R-77 or R-73 air-to-air missiles, with these being primarily for defense against pursuers if detected by the rearward facing radar.[13] The maximum weight of any single munition carried is 4,000 kg (8,800 lb). Its stand-off weapons have a range of up to 250 km (160 mi; 130 nmi).[70][71] A Khibiny electronic countermeasures (ECM) system is fitted as standard)
