Tupolev Tu-95

The Tupolev Tu-95 (Туполев Ту–95) (NATO reporting name Bear) is the most successful and longest-serving Tupolev strategic bomber and missile carrier built by the Soviet Union during the Cold War.

The Tu-95 is still in service, as of 2008, and is expected to remain in service with the Russian Air Force until at least 2040.^[1] The Tu-95 is powered by four Kuznetsov NK-12 turboprop engines, each driving contra-rotating propellers, and remains the fastest propeller-driven aircraft to go into operational use. Its wings are swept back at 35 degrees, a very sharp angle by the standards of propeller-driven aircraft.

To date, it remains the only turboprop-powered strategic bomber to have entered operational service. A naval development of the bomber is designated Tu-142.

Design and development

The design bureau led by Andrei Tupolev designed the Soviet Union's first intercontinental bomber, the 1949 Tu-85, it was a scaled up version of the Tu-4, a B-29 Superfortress copy. The Tu-85 was deemed to be inadequate against the new generation of American all-weather interceptors. A new requirement was issued to both Tupolev and Myasishcev design bureaus in 1950, it had to have an un-refuelled range of 8000km (4,970 miles), far enough to threaten key targets in the United States. Other goals included the ability to carry a 11000kg (24,250lb) load over the target. The big problem for Tupolev was the engine choice, the first generation jet engines had a large fuel consumption and turboprops gave a better range. Also in a parallel race to build an intercontinental bomber was Boeing, but the recently developed J57 enabled the B-52 Stratofortress to be jet-powered. The Myasischev bureau decided to use early jet engines. Tupolev decided to work on the problems with high-speed turboprops for the new bomber now designated the Tu-95.

With eight-bladed contra-rotating propellers the engine that emerged was the Kuznetsov NK-12 with a nominal 12,000 eshp (8948kW) power rating. Although the engine was advanced, the fuselage design was conventional: it was low-wing cantilever monoplane with 35 degrees of sweep. The angle ensured that the main wing spar passed though the fuselage in front of the bomb bay. It had a retractable tricycle landing gear, with the main gear retracting rearwards.The first aircraft flew in 1953.

For a long time, the Tu-95 was known to Western 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 Western intelligence agents, the name continued to be used outside the Soviet Union.

Like its American counterpart, the B-52 Stratofortress, the Tu-95 has continued to operate in the Russian Air Force while several 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 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. During and after the Cold War, the Tu-95's utility as a weapons platform has been eclipsed only by its usefulness as a diplomatic icon.

Development of the turboprop powered Tu-95 began in the 1950s as an intercontinental bomber when the Tu-4 showed that piston engines were not powerful enough to fulfill that role, and the AM-3 jet engines of the proposed T-4 intercontinental jet bomber did not provide it with enough range.^[2]

The Tu-95 development was officially approved by the government on 11 July 1951, resulting in the test of the first prototype 95/1 on 12 November 1952. Series production of the airplane started in January 1956.

Initially the United States Department of Defense did not take the Tu-95 seriously, as estimates showed it had a maximum speed of 400 mph (644 km/h) with a range of 7,800 miles (12,500 km).^[3] These numbers had to be revised upward numerous times.

Operational history

Cold War icon

The Tu-95RT variant in particular was a veritable icon of the Cold War as it performed a vital maritime surveillance and targeting mission for other aircraft and surface ships and submarines. It was identifiable by a large bulge under the fuselage, which housed a radar antenna that was used to search for and target surface ships. The US Navy placed high priority in intercepting the Tu-95RT aircraft at least two hundred miles from the carrier with its F-14 Tomcat interceptors, which would then escort the Tu-95. On occasion, USN Tomcats demonstrated an ability to intercept Tu-95RT aircraft at ranges up to 1,000 miles from the fighters' carrier battle group.^{[citation needed]}

During interceptions Tu-95 tail gunners typically kept their twin cannon pointed upwards as to not antagonize the intercepting fighters. Similarly, NATO rules of engagement for interceptions restricted aircrews from locking onto the Tu-95 with fire control radars lest this be misinterpreted as a hostile act.

During the height of the Cold War, the long range of the Tu-95 was demonstrated weekly as a pair of Tu-95s would fly from the Kola peninsula to Cuba along the east coast of the United States, escorted continuously along the way.^{[citation needed]}

The Tu-95 dropped the Tsar Bomba in 1961.

Encounters in the air

Western fighters were — and are — often sent to intercept Tu-95s as they performed their missions along the periphery of NATO airspace, often in very close formation.

Concerning the performance of the aircraft, it has been reported by many fighter pilots that the Tu-95 was able to out-accelerate them for a short distance, especially with the SEPECAT Jaguar^{[citation needed]}. There are also tales of the Soviet pilots suddenly swerving to push the escorts off course or cause them to rapidly decelerate. This went both ways, however. In the 1980s a Royal Norwegian Air Force F-16 collided with a Tu-95 while escorting it out of Norwegian airspace. Apparently, the Norwegian pilot had been edging closer and closer to the Tupolev before being caught in the prop wash and having a wingtip torn off in the resulting collision. Both planes landed safely.

As late as 1999, Russian Tu-95s, usually flying in pairs, have come within striking distance both of the Iceland/Greenland route of North Atlantic and Alaska/Bering Sea route of North Pacific. In June of 1999, the Tu-95s, along with two Tu-160s, turned back after being intercepted by U.S. fighters. A similar incident occurred in September but the Tu-95s turned back without making contact.

Encounters after 2000

• April 2002 — two Tu-95 Bear H aircraft flew within 37 miles of Alaska, and were intercepted by two F-15s.^[4]
  • 29 January 2004 — a Tu-95 flew over the USS Kitty Hawk in the Sea of Japan.
  • 29 September 2006 — NORAD scrambled Canadian CF-18s from CFB Cold Lake in Central Alberta and American F-15s out of an airbase in Alaska to intercept "a number of the Russian Tu-95 Bear heavy bombers participating in an annual Russian air force exercise near the coast of Alaska and Canada." This launch was a result of the bombers penetrating the North American Air Defense Identification Zone (ADIZ).^[5]
    • May 2007 — the Royal Air Force scrambled two Tornado fighters from RAF Leuchars in Scotland to intercept a Tu-95 observing the Royal Navy exercise Neptune Warrior.^[6]
      • 17 July 2007 — two Royal Norwegian Air Force F-16s (from Bodø, Norway) and subsequently two RAF Tornados (from RAF Leeming, England) intercepted two Tu-95s as they allegedly made their way down the Norwegian coast towards Scotland.^[7][8]
        • August 2007 — two Tu-95s flew towards the U.S. base on Guam, where they were intercepted by U.S. fighter planes. Maj Gen Pavel Androsov of the Russian Air Force told a news conference, "We renewed the tradition when our young pilots flew by Guam in two planes. We exchanged smiles with our counterparts who flew up from a U.S. carrier and returned home."^[9][10] However, the Pentagon denied that any aircraft were sent up, saying that the proximity of the bombers was not close enough to prompt a response from the carriers.^[11]
          • 17 August 2007 — two RAF Typhoons were launched to intercept and shadow a Tu-95 that had veered towards British airspace over the North Sea. The Tu-95 later turned away from UK airspace.^[12]
            • 5 September 2007 — six Russian bombers were intercepted by six F-15s from Elmendorf Air Force Base, about 50 miles from the northwest coast of Alaska.^[13]
              • 6 September 2007 — Two Norwegian F-16s tracked eight Tu-95s over the Barents Sea^[14] as they neared Norwegian airspace. The bombers flew past Norway and continued towards British airspace where four RAF Tornados were scrambled from RAF Leeming (in two waves of two), before the Russian planes turned away.^[15] It was the same day that Canadian Forces' CF-18s and Russian Tu-95s met outside Canadian airspace near Inuvik, Northwest Territories. The CF-18s were scrambled when Tu-95s were seen flying outside Canadian airspace.^[16]
                • 22 November 2007 — F-22A Raptors of the 90th fighter squadron performed their first intercept of two Russian Tu-95MS 'Bear-H' bombers in Alaska. This was the first time that F-22s had been called to support a NORAD mission.^[17][18]
                  • 9 February 2008 — 24 aircraft including F-15 Eagles and an E-767 AWAC from the Japanese air force scrambled and gave "a notice, then a warning and another a notice and a warning," as a Russian Tu-95MS 'Bear-H' violated the country's airspace during a three-minute flyover of Sofugan in the Izu Islands. Japan formally issued a strong protest, demanded prevention of future incidents and presented a protest note to the Russian Embassy in Tokyo. Russian officials conversely stated that four Tupolev Tu-95 bombers completed a 10-hour mission over the Pacific on Saturday, but "our strategic aviation planes did not violate Japanese airspace." ^[19][20][21]
                    • 9 February 2008 — in the Western Pacific, a Russian Tu-95 flew over the aircraft carrier USS Nimitz twice, at a low altitude of about 2,000 feet, while another bomber circled about 58 miles out. Four American F/A-18 fighters from the carrier were scrambled and tracked the bombers.^[22][23]
                      • 5 March 2008 — Off the eastern coast of South Korea, a Russian Tu-95 or Tu-142 flew over USS Nimitz and was intercepted by two F/A-18 Hornets at an altitude of 2,000 feet at a distance of about 3-5 miles. Four South Korean F-16s were also scrambled to intercept the bomber.^[24][25]

                        Present and future status

                        All Tu-95s now in Russian service are the Tu-95MS variant, built in the 1980s and 1990s. On August 18, 2007, Russian President Vladimir Putin announced that Tu-95 patrols would resume after having been terminated 15 years prior.^[26]

                        Russian Tu-95s reportedly took part in a naval exercise off the coasts of France and Spain in January 2008, alongside Tu-22M3 Backfire strategic bombers and airborne early warning aircraft.^[27]

Molodchi.^[28] The 106th TBAD incorporated the 409th TBAP (Heavy Bomber Air Regiment ) (commander — Colonel M.M. Charitonov) which was raised late in 1956 and the 1006th TBAP (commander — Colonel V.P. Pavlov) raised in 1956. The 106th TBAD's base was Uzin near Kiev. The 1223rd TBAP in Semipalatinsk, under the command of Hero of the Soviet Union colonel V.M. Bezbokov, was raised in 1957, within the 79th Air Division (commander — twice Hero of the Soviet Union General Major M.P. Taran). The 1223rd TBAP's targets were the north of the USA and Canada.
