Based on Sukhoi Su-27 'Flanker', the two-seat Su-34 is 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 EW counter-measures deployed, as well as for air reconnaissance.
The Su-34 had a muddied and protracted beginning. In the mid-1980s, Sukhoi began developing a new tatical multirole combat aircraft to replace the swing-wing Su-24, which would incorporate a host of conflicting requirements. The bureau thus selected the Su-27, which excelled in maneuverability and range, and could carry a large payload, as the basis for the new fighter-bomber. More specifically, the aircraft was developed from T10KM-2, the naval trainer derivative of the Sukhoi Su-27K. The development, known internally as T-10V, was shelved at the end of the 1980s sharing the fate of Soviet aircraft carrier Ulyanovsk; this was the result of the political upheaval in the Soviet Union and its subsequent disintegration.
In August 1990 a photograph taken by a TASS officer showed an aircraft making a dummy approach towards Tbilisi carrier. The aircraft, subsequently and erroneously labelled Su-27KU by Western intelligence, made its maiden flight on 13 April 1990 with Anatoliy Ivanov at the controls. Converted from an Su-27UB with the new distinctive nose, while retaining the main undercarriage of previous Su-27s, it was a prototype for the Su-27IB (Istrebitel Bombardirovshchik, or "fighter bomber"). It was developed in parallel with the two-seat naval trainer, the Su-27KUB. However, contrary to earlier reports, the two aircraft are not directly related. Flight tests continued throughout 1990 and into 1991.
In 1992, the Su-27IB was displayed to the public at the MosAeroshow (later renamed "MAKS Airshow"), where it demonstrated aerial refuelling with an Il-78, and performed an aerobatic display. The aircraft was officially unveiled on 13 February 1992 at Machulishi, where Russian President Boris Yeltsin and the CIS leaders were holding a summit. The following year the Su-27IB was again displayed at the MAKS Airshow.
The next prototype, and first pre-production aircraft, T10V-2, first flew on 18 December 1993 at the controls of Igor Votintsev and Yevgeniy Revoonov. Built at Novosibirsk, where Su-24s were constructed, this aircraft was visibly different from the original prototype; it had modified vertical stabilizers, twin tandem main undercarriage and a longer "sting", which houses a rearward-facing warning radar. The first aircraft built to production standard made its first flight on 28 December 1994. It was fitted with a fire-control system, at the heart of which was the Leninets OKB-designed V004 passive electronically scanned array radar. It was different enough from the earlier versions that it was re-designated the "Su-34". However, at the 1995 Paris Air Show, the Su-34 was allocated the "Su-32FN" designation, signalling the aircraft's potential role as a shore-based naval aircraft for the Russian Naval Aviation. Sukhoi also promoted the Su-34 as the "Su-32MF" (MnogoFunksionalniy, "multi-function").
Budget restrictions led the programme to stall repeatedly. Nevertheless, flight testing continued, albeit at a slow pace. The third pre-production aircraft first flew in late 1996.
The aircraft shares most of its wing structure, tail, and engine nacelles with the Su-27/Su-30, with canards like the Su-30MKI/Su-33/Su-27M/35 to increase static instability (higher manoeuvrability) and to reduce trim drag. The aircraft has an entirely new nose and forward fuselage with a cockpit providing side-by-side seating for a crew of two. 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. When equipped with a full weapons loadout, the Su-34 has a maximum range of 4,000 km without refuelling, this can be extended further via aerial refueling. When operating at its operational maximum, the airframe can withstand an 'overload' of up to +9G.
The Su-34 has a three-surface planform, with a conventional horizontal tailplane, twin-tail at the rear and a pair of canard foreplanes in front of the wings for extra lift (force) and more manoeuvring capability. The Su-34 has 12 hardpoints for up to 12,000 kilograms of ordnance, intended to include the latest Russian precision-guided weapons. It retains the Su-27/Su-30's 30 mm GSh-30-1 cannon, and the ability to carry air-to-air missiles R-77 (pcs 6) and R-73 (still 6). The maximum weight of any single munition carried is 4000 kg, with a maximum munitions load the maximum attack range is 250 km. A Khibiny Electronic countermeasures (ECM) system is fitted as standard.
The Su-34's most distinctive feature is the unusually large flight deck. Much of the design work went into crew comfort. The two crew members sit side by side in a large cabin, with the pilot-commander to the left and navigator/operator of weapons to the right in NPP Zvezda K-36dm ejection seats. An advantage of the side by side cockpit is that duplicate instruments are not required for each pilot. Since long missions require comfort, the pressurization system allows operation up to 10,000 metres (32,800 ft) without oxygen masks, which are available for emergencies and combat situations. The crew members have room to stand and move about the cabin during long missions. The space between the seats allows them to lie down in the corridor, if necessary. A toilet and a galley are located behind the crew seats. A ladder attached to the nose landing gear and a hatch in the cockpit floor is used to enter the cockpit. The cockpit is a continuous capsule of armour. The Helmet Mounted Display System (HMDS) acts as a command center: precision target designation of all onboard weapons is tied to the movement of the pilot's head and eyes.
Maximum detection range for the passive electronically scanned array forward radar is 200–250 km, to cover the rear a second aft-facing radar is mounted. The main radar can simultaneously attack four targets (in the air, on land or on the water). The rear warning radar system can warn of attack from behind and allow it to fire its R-73 (missile)s against pursuers without needing to turn the aircraft. The rear radar is unofficially called the N-012. The Su-34 reportedly has a a frontal radar cross-section an order of magnitude smaller than prior generation fighters, use stealth.
The Su-34's long range was shown in a July 2010 exercise when Su-34s and Su-24Ms were moved from Russian bases in Europe to one on the Pacific coast, 6,000 kilometres away, which requires in-flight refuelling. The exercise included aircraft carrying weapons at full load, simulated delivering them on a target before arriving at the Pacific coast base. Su-24Ms were refuelled three times, while the Su-34 was refuelled twice.
The Russian Air Force completed the final stage of the state tests on 19 September 2011. The aircraft entered service in early 2014. The Su-34 was rumoured to have been used by Russian command during the 2008 South Ossetia war. Russia plans to have 92 in use to 2020. Later planned to get up to 200.
Orders and deliveries
An initial batch of eight Su-32 were completed by the Novosibirsk factory in 2004. In March 2006, Russia's Minister of Defence Sergei Ivanov announced that the purchase of the first 5 pre-production Su-34s for the Russian Air Force. In late 2008, a second contract was signed for delivery of 32 aircraft by 2015. A total of 70 aircraft were to be purchased by 2015 to replace some 300 Russian Su-24s, which were then undergoing a modernization program. Ivanov claimed that as it is "many times more effective on all critical parameters", fewer of these newer bombers are required than the old Su-24 it replaces. In December 2006, Ivanov revealed that approximately 200 Su-34s were expected to be in service by 2020; and was confirmed by Air Force chief Vladimir Mikhaylov on 6 March 2007. Two Su-34s were delivered in 2006-2007, and three more were delivered by the end of 2009.
The Russian Air Force received another four Su-34s on 28 December 2010, as combat units in airbases first received six Su-34s in 2011. Delivery came in the form of two contracts, the first in 2008 for 32 aircraft and the second in 2012 for a further 92 aircraft, totaling 124 to be delivered by 2020. In December 2012, Sukhoi reportedly delivered five aircraft under the 2012 State Defense Order. In January 2013, Sukhoi delivered a batch of 5 Su-34s, flying directly from the Novosibirsk aircraft plant to an air base in Voronezh, Russia. On 6 May 2013, the first Su-34s under the 2013 defence procurement plan were delivered.
On 9 July 2013, three more Su-34s were delivered in an official acceptance ceremony held at the Novosibirsk Aircraft Plant. These three aircraft were already in the new Russian Air Force camouflage scheme. By the end of 2013, Sukhoi completed the 2008 contract and started deliveries on 2012 contract.
In August 2013, Sukhoi signed a contract with the Kazan-based Radiopribor holding company for 184 "friend-or-foe" transponders for the Su-34 to be delivered by 2020.
On 10 June 2014, Russia1 TV reported a further delivery of Su-34s was made to the 559th Regiment at Morozovsk. Another three aircraft were delivered on 18 July 2014. Six more were delivered on 15 October 2014. 18 aircraft were delivered in 2014, and 20 planned to be delivered in 2015.
