The Tupolev Tu-95 (russian: Туполев Ту-95; NATO reporting name: "Bear") is a large, four-engine turboprop-powered strategic bomber and missile platform. First flown in 1952, the Tu-95 entered service with the Soviet Union in 1956 and is expected to serve the Russian Aerospace Forces until at least 2040. A development of the bomber for maritime patrol is designated Tu-142, while a passenger airliner derivative was called Tu-114. The aircraft has four Kuznetsov NK-12 engines with contra-rotating propellers. It is the only propeller-powered strategic bomber still in operational use today. The Tu-95 is one of the loudest military aircraft, particularly because the tips of the propeller blades move faster than the speed of sound. Its distinctive swept-back wings are set at an angle of 35°. The Tu-95 is unique as a propeller-driven aircraft with swept wings that has been built in large numbers.


Design and development


The design bureau, led by Andrei Tupolev, designed the Soviet Union's first intercontinental bomber, the 1949 Tu-85, a scaled-up version of the Tu-4, a Boeing B-29 Superfortress copy. A new requirement was issued to both Tupolev and Myasishchev design bureaus in 1950: the proposed bomber had to have an un-refueled range of , far enough to threaten key targets in the United States. Other goals included the ability to carry an load over the target. Tupolev was faced with selecting a suitable type of powerplant: the Tu-4 showed that piston engines were not powerful enough for such a large aircraft, and the AM-3 jet engines for the proposed T-4 intercontinental jet bomber used too much fuel to give the required range. Turboprop engines were more powerful than piston engines and gave better range than the turbojets available at the time, and gave a top speed between the two. Turboprops were also initially selected for the Boeing B-52 Stratofortress to meet its long range requirement, and for the British long-range transport aircraft, the Saunders-Roe Princess, the Bristol Brabazon and the Bristol Britannia. Tupolev proposed a turboprop installation and a Tu-95 design with this configuration was officially approved by the government on 11 July 1951. It used four Kuznetsov coupled turboprops, each fitted with two contra-rotating propellers with four blades each, with a nominal power rating. The engine, advanced for its time, was designed by a German team of ex-Junkers prisoner-engineers under Ferdinand Brandner. The fuselage was conventional with a mid-mounted wing with 35 degrees of sweep, an angle that ensured that the main wing spar passed through the fuselage in front of the bomb bay. Retractable tricycle landing gear was fitted, with all three gear strut units retracting rearwards, with the main gear units retracting rearwards into extensions of the inner engine nacelles. The Tu-95/I, with 2TV-2F engines, first flew in November 1952 with test pilot Alexey Perelet at the controls. After six months of test flights this aircraft suffered a propeller gearbox failure and crashed, killing Perelet. The second aircraft, Tu-95/II used four 12,000 eshp Kuznetsov NK-12 turboprops which proved more reliable than the coupled 2TV-2F. After a successful flight testing phase, series production of the Tu-95 started in January 1956. For a long time, the Tu-95 was known to U.S./NATO intelligence as the Tu-20. While this was the original Soviet Air Force designation for the aircraft, by the time it was being supplied to operational units it was already better known under the Tu-95 designation used internally by Tupolev, and the Tu-20 designation quickly fell out of use in the USSR. Since the Tu-20 designation was used on many documents acquired by U.S. intelligence agents, the name continued to be used outside the Soviet Union. Initially, the United States Department of Defense evaluated the Tu-95 as having a maximum speed of with a range of . These numbers had to be revised upward numerous times. Like its American counterpart, the Boeing B-52 Stratofortress, the Tu-95 has continued to operate in the Russian Air Force while several subsequent iterations of bomber design have come and gone. Part of the reason for this longevity was its suitability, like the B-52, for modification to different missions. Whereas the Tu-95 was originally intended to drop free-falling nuclear weapons, it was subsequently modified to perform a wide range of roles, such as the deployment of cruise missiles, maritime patrol (Tu-142), and even civilian airliner (Tu-114). An AWACS platform (Tu-126) was developed from the Tu-114. An icon of the Cold War, the Tu-95 has served not only as a weapons platform but as a symbol of Soviet and later Russian national prestige. Russia's air force has received the first examples of a number of modernised strategic bombers in Tu-95MSs following upgrade work. Enhancements have been confined to the bomber's electronic weapons and targeting systems. Modernization of the first batch was completed in March 2020.


Tu-116


Designed as a stopgap in case the Tu-114A was not finished on time, two Tu-95 bombers were fitted with passenger compartments. Both aircraft had the same layout: office space, a passenger cabin consisting of 2 sections which could each accommodate 20 people in VIP seating, and the rest of the cabin configured as a normal airliner. Both aircraft were eventually used as crew ferries by the various Tu-95 squadrons. One of these machines is preserved at Ulyanovsk Central Airport.


Modernization


Currently, ongoing modernization of the Russia's Tu-95MS bombers is aimed primarily on the aircraft armament, namely adaptation of the new Kh-101/102 stealth cruise missile. The modernization includes installation of four underwing pylons for up to 8 Kh-101/102 cruise missiles as well as adjusting aircraft's main weapons bay for cruise missiles of size the Kh-101/102 (). Besides, the modernized Tu-95MS aircraft use radio-radar equipment and target-acquiring/navigation system based on GLONASS. The first Tu-95 modernized to carry the Kh-101/102 missiles was the Tu-95MS ''Saratov'', rolled out at the Beriev aircraft plant in Taganrog in early 2015. It was transferred to the Russian Air Force in March 2015. Since 2015, the serial modernization is carried out also by the Aviakor aircraft plant in Samara at a rate of three aircraft per year. The first Tu-95 modernized by the Aviakor was the Tu-95MS ''Dubna'', transferred to the Russian Air Force on 18 November 2015. In the future, Tu-95MSs are to be upgraded also with the new Kuznetsov NK-12MPM turboprop engines for increased flight range, combat load and reduced noise and vibrations and with the SVP-24 sighting and computing system from the Russian company Gefest & T. More complex modernization of the Tu-95MS16 bombers, known as "Tu-95MSM", is currently under development by Tupolev under a contract issued by the Russian Defence Ministry on 23 December 2009. This modernization is to include installation of the new Novella-NV1.021 radar, instead of the current Obzor-MS, installation of the SOI-021 information display system and the Meteor-NM2 airborne defense complex. In addition, the aircraft modernized to the "MSM" variant will be equipped with the upgraded Kuznetsov NK-12MPM turboprop engines. A contract for first modernized aircraft was signed in February 2018 with first flight scheduled for end of 2019. The first Tu95 MSM made its maiden flight on 22 August 2020.


Operational history





Soviet Union


The Tu-95RT variant in particular was a veritable icon of the Cold War as it performed a maritime surveillance and targeting mission for other aircraft, surface ships and submarines. It was identifiable by a large bulge under the fuselage, which reportedly housed a radar antenna that was used to search for and detect surface ships. A series of nuclear surface tests were carried out by the Soviet Union in the early- to mid-1960s. On October 30, 1961, a modified Tu-95 carried and dropped the AN602 device named ''Tsar Bomba'', which was the most powerful thermonuclear device ever detonated. Video footage of that particular test exists since the event was filmed for documentation purposes. The footage shows the specially adapted Tu-95V plane – painted with anti-flash white on its ventral surfaces – taking off carrying the bomb, in-flight scenes of the interior and exterior of the aircraft, and the detonation. The bomb was attached underneath the aircraft, which carried the weapon semi-externally since it could not be carried inside a standard Tu-95's bomb-bay, similar to the way the B.1 Special version of the Avro Lancaster did with the ten-tonne Grand Slam "earthquake bomb". Along with the ''Tsar Bomba'', the Tu-95 proved to be a versatile bomber that would deliver the RDS-4 Tatyana (a fission bomb with a yield of forty-two kilotons), RDS-6S thermonuclear bomb, the RDS-37 2.9-megaton thermonuclear bomb, and the RP-30-32 200-kiloton bomb. The early versions of this bomber lacked comfort for their crews. They had a dank and dingy interior, and there was neither a toilet nor a galley in the aircraft. Though the living conditions on the bomber were unsatisfactory, the crews would often take two 10-hour mission trips a week to ensure combat readiness. This gave an annual total of around 1,200 flight hours. The bomber had the best crews available due to the nature of their mission. They would undertake frequent missions into the Arctic to practice transpolar strikes against the United States. Unlike their American counterparts, they never flew their missions carrying nuclear weapons. This hindered their mission readiness due to the fact that live ammunition had to come from special bunkers on the bases and loaded into the aircraft from the servicing trench below the bomb bay, a process that could take two hours.


Russia


In 1992, newly independent Kazakhstan began returning the Tu-95 aircraft of the 79th Heavy Bomber Aviation Division at Dolon air base to the Russian Federation. The bombers joined those already at the Far Eastern Ukrainka air base. On 17 August 2007, Russian President Vladimir Putin announced that Russia was resuming the strategic aviation flights stopped in 1991, sending its bombers on long-range patrols. NATO fighters are often sent to intercept and escort Tu-95s as they perform their missions along the periphery of NATO airspace, often in close proximity to each other. Russian Tu-95s reportedly took part in a naval exercise off the coasts of France and Spain in January 2008, alongside Tu-22M3 strategic bombers and A-50 airborne early-warning aircraft. During the Russian Stability 2008 military exercise in October 2008, Tu-95MS aircraft fired live air-launched cruise missiles for the first time since 1984. The long range of the Kh-55 cruise missile means the Tu-95MS can once again serve as a strategic weapons system. In July 2010, two Russian Tu-95MS strategic bombers set a world record for a non-stop flight for an aircraft in the class, when they spent more than 43 hours in the air. The bombers flew through the Atlantic, Arctic and Pacific oceans and the Sea of Japan, covering in total more than with four mid-air refuelings. The main task was to check the performance of the aircraft during such a long flight, in particular monitoring the engines and other systems. On 17 November 2015, Tu-95s had their combat debut, being employed for the first time in long-range airstrikes as part of the Russian military intervention in the Syrian Civil War. On 17 November 2016, modernized Tu-95MS strategic bombers performed their first combat deployment, launching the Kh-101 cruise missiles on several militant positions in Syria. On 5 December 2017, two Tu-95MS strategic bombers and two Il-76MD transport aircraft landed for the first time at the Biak Air Base in Indonesia. The bombers covered more than with mid-air refueling before landing at the air base. During the course of their visit, the Tu-95's crews conducted their first patrol flights over the southern Pacific, staying airborne for more than eight hours.


Incidents


* In 1968 two planes were lost over the Black Sea during a training flight. Both planes fell into the sea, one of them was to be salvaged later, and only one crew member out of 18 survived. These planes had been operating from AFB Uzyn in Ukraine. * On June 8, 2015 a Tu-95 ran off a runway at the Ukrainka bomber base and caught fire during take-off in the far eastern Amur region. As a result, one crew member was killed. * On July 14, 2015 it was reported that a Tu-95MS had crashed outside Khabarovsk, killing two of seven crew members.
