Tupolev Tu-95MS (Nato code name: Bear-H) is a four-engine, long-range, turboprop, strategic bomber / missile carrier developed by Russian aerospace and defence company JSC Tupolev Design Bureau. The carrier is currently in service with the Russian Air Force.
Based on the airframe of Tu-142 (Bear F) maritime patrol aircraft, the Tu-95MS aircraft is a modernised version of the Tu-95 Bear strategic bomber. It is equipped with stand-off cruise missiles and can be deployed in combat missions to defeat cruise missiles and strategic enemy targets.
The Russian Defence Ministry intends to procure 20 modernised bombers by the end of 2016. The aircraft are expected to remain in service with them until 2040.
Tu-95MS strategic bomber combat aircraft orders and deliveries
A Tu-95MS prototype made first flight in September 1979. Serial production of the bomber was carried out at Kuibyshev Aircraft Works (now OJSC Aviakor Aviation Plant) in Samara between 1981 and 1992. The aircraft have been deployed by the 121st Heavy Bomber Regiment at Engels Air Base and the 73rd Heavy Bomber Aviation Division at Ukrainka Air Base.

In December 2014, Tupolev handed over two upgraded Tu-95MS strategic bombers with improved avionics and flying efficiency to the Russian Air Force, as part of the state defence order. A further delivery of upgraded Tu-95MS was made in January 2015.
Flight tests
Two Tu-95MS aircraft performed a 17-hour patrol flight over the Aleutian Islands in May 2011. It was followed by a 10h air patrol flight over the Pacific Ocean in November 2011. Two Tu-95MS strategic bombers also performed a patrol flight over the Arctic Ocean for 20h in April 2012. Another patrol flight, which lasted 13h, was executed over the Norwegian Sea in November 2013.
The Tu-95MS successfully launched six high-precision cruise missiles at ground targets during a tactical flight test that lasted 7h in June 2014.
Design and features of Tu-95MS strategic bomber
combataircraft.com
The Tu-95MS strategic bomber features high-aspect ratio spar wing design and an improved, all-metal airframe. It is capable of engaging major stationary enemy targets under extreme weather conditions both during day and at night.
The aircraft is 49.6m-long and 13.3m-high, and is equipped with semi-monocoque fuselage and a retractable tricycle landing gear consisting of steerable twin-wheel nose unit and four-wheeled main units. Its maximum take-off and landing weights are 185t and 135t respectively and its maximum payload capacity is 20,000kg. The wings are swept back at 35° and the wing span is 50.05m.
The cabin in the front section of the fuselage accommodates a crew of seven, including a pilot and a co-pilot.
Armament
The Tu-95MS Bear-H aircraft is armed with two Gryazev-Shipunov GSh-23 twin-barrelled, 23mm automatic cannons at the rear for self-defence against airborne threats. Each cannon has a rate of fire of 2,400 rounds a minute. Six 2,500km-range Kh-15 air-launched cruise missiles are carried in the drum launcher.

KH-15 (AS-16 KICKBACK)
Even the fast KSR-5 left something to be desired. Storable rocket propellants are corrosive and highly toxic, making them difficult to handle, and the KSR-5’s range and capability were inadequate. In the 1970s, the US Navy developed the Grumman F-14 Tomcat interceptor, which featured long-range Phoenix air-to-air missiles. The Tomcat / Phoenix combination, backed up by the Grumman E-2C Hawkeye carrier-based radar early warning aircraft, presented a clear threat to Soviet bombers operating in the anti-ship role. The Hawkeye could provide long-range “eyes” for the Tomcat, which had long range and endurance, allowing it to fire a Phoenix at a Soviet bomber long before the Red aircraft got within range of a carrier group. If the bomber did manage to take a shot with a cruise missile, the Phoenix might well shoot the missile down.
The Tomcat / Phoenix / Hawkeye threat led the Soviets to develop the low-level launch versions of the Kh-22 and KSR-5 missiles, and also to work on a missile that was much harder to intercept. The Soviets were impressed enough by the Boeing SRAM that Raduga developed an equivalent, the “Kh-15 (AS-16 Kickback)”, which has almost the same external appearance as the SRAM. It was the first Soviet large ASM with solid-fuel rocket propulsion.
The Kh-15 is a simple spike of a missile with three tailfins. The resemblance to SRAM is so close that it is tempting to refer to the Kh-15 as “SRAMski”. Unlike SRAM, however, as with the other large Soviet ASMs, the Kh-15 was designed for both strategic and anti-ship attack. There are three versions: the standard Kh-15 nuclear-armed strategic variant, with inertial guidance only; a conventionally-armed anti-ship variant, the “Kh-15A”, with an active radar terminal seeker; and an antiradar variant, the “Kh-15P”, with a passive radar seeker. An export version of the Kh-15A, the “Kh-15S”, was also built. After launch, the missile climbs to the edge of space and then dives on the target steeply at Mach 5, making it very hard to hit.
Raduga began work on the Kh-15 in the late 1960s and it was accepted for service in the early 1980s. A Tu-22M Backfire bomber can carry six Kh-15s in a revolver launcher in the weapons bay, plus four more under the wings. It is also carried by the Tupolev Tu-160 Blackjack bomber.

The Tu-95MS-6 variant can be equipped with six Raduga Kh-55 (AS-15) subsonic air-launched cruise missiles in a rotary launcher, whereas the Tu-95MS-16 variant can carry 16 Kh-55 missiles externally.
Raduga Kh-55 (AS-15) subsonic air-launched cruise missiles
The Kh-55 has pop-out wings and fins, and has an INS to get to the target area and terrain-following system for terminal attack. It differs visibly from the Tomahawk in that its entire R95-300 turbofan engine is extended out of the fuselage after launch, not just the air intake.

Kh-55 series missiles are carried by Bear and Blackjack heavy bombers. The Bear can carry six in an internal rotary launcher. It can also carry more Kh-55s externally, though in an overload flight condition: two are carried on a stores attachment between the fuselage and inboard engine, and three are carried on a stores attachment between the two engines on each wing, for a total of ten missiles. Roughly 1,500 Kh-55s were built into the early 1990s.
* A naval version of the Kh-55SM designated “3K-10 Granat” (NATO codename “SS-N-21 Sampson”) was built in parallel. Sources hint that it was strictly submarine launched. There are sketchy reports of an experimental derivative of the 3K-10 named the “3M-55 (SS-N-27)” that is intended for the antiship role, and has a “warhead” that is actually a solid fuel missile that performs a terminal attack at Mach 2.5 speed.
There was also production of a limited batch of a ground-launched version for the Red Army, the “RK-55” (NATO codename “SSC-X-4 Slingshot”) that was comparable to the US GLCM, but the INF treaty that killed off the GLCM killed off the RK-55 as well.

The aircraft can be further modified to carry up to eight Kh-101 air-launched cruise missiles or 14 Kh-65 anti-ship missiles.
Kh-101 air-launched cruise missile
The Kh-101 is an advanced cruise missile under development to eventually replace the Kh-55 missile onboard the Soviet/Russian strategic bombers such as Tu-160 and Tu-95. The Kh-101 has a 400-kg conventional warhead, stealth features, high subsonic speed and low altitude flight profile. The conventionally-armed Kh-101 has also been referred to as the Russian counterpart to the United States Air Force AGM-129 air launched cruise missile.
The Kh-101 has a highly accurate navigation system based on the GLONASS satellite navigation system and a highly accurate Inertial Navigation System (INS) as backup with a terminal TV-based seeker for precision-attack missions. The Kh-101 development has been strongly influenced by the successes of US military campaigns in the late 1990s and the emerging role of standoff weapons in modern conflicts. Up to eight (Tu-95) or up to 12 (Tu-160) of these missiles can be carried by a single Russian heavyweight bomber.
The Kh-101 and Kh-102 air launched cruise missile are supposed to be members of the same family of missiles sharing components and overall performance. The main difference between them is their warhead. As of 2006, the Kh-101 was near ready for deployment. Unconfirmed reports suggest that the missile entered service in early 2012 or later in 2013/2014.

Tu-95MSM
The modernization of the strategic bombers of the Russian Air Force, is being carried out, in slow tempo though, with airplanes like the Tu-95MS and the Tu-160. Until 2015 the Air Force plans on upgrading up to 159 bombers (including the Tu-22M3). The initial work of upgrading the Tu-95MS started in 1992, with the main objective of setting up the new rocket system“Sigma”.
In the fall of 1999, the first modernized Tu-95MSM was delivered. Along with the modernization of the aircrafts, work is being done on expanding their “service life” up to 30 years.
The upgraded bombers scheduled to remain in service until 2025
The modernization program (to “MSM” level) concerns:

The strategic bomber is installed with ANS-2009 celestial navigation system, developed by Concern Radio-Electronic Technologies (KRET), to determine the plane’s coordinates. The onboard new-generation BINS-SP-2M strapdown inertial navigation system, also developed by KRET, determines location of objects and provides navigation and flight data in the absence of satellite navigation.

ANS-2009 celestial navigation system
The ANS-2009 celestial navigation system, developed by KRET, accurately determines an aircraft’s coordinates based on the position of the stars.
“This is the most reliable method during combat when navigation satellite systems are disabled by the enemy,” said Vladimir Mikheev, Advisor to the First Deputy of KRET, as quoted by TASS. “ANS-2009 can be installed on a plane along with the strapdown inertial navigation systems and does not require external guidance or signals.”
The device is designed for long-range Russian aircraft and is currently used by three types of aircraft, the Tu-95MS, Tu-22M3, and Tu-160, which will be updated to meet the needs of the Air Force. As Air Force Commander Viktor Bondarev noted earlier, the military plans to buy at least 50 of these aircraft.
It is expected that, in 2019 or 2020, the new long-range strategic bomber PAK DA will take to the skies. According to Vladimir Mikheev, the achievements obtained in creating the ANS-2009 will be implemented on the PAK DA. Source kret.com
BINS-SP2 strapdown inertial navigation system

The BINS-SP2 architecture is based on three laser gyroscopes and three quartz accelerometers. The system can establish the platform’s coordinates and motion variables in the absence of external data inputs.
The system was developed by Moscow Institute of Electromechanics and Automatics, a subsidiary of Radioelectronic Technologies. General director Alexey Kuznetsov says the BINS-SP2 can operate at temperatures between –60° and +60° C, and at altitudes up to 25 km.
Anatoly Chumakov, general director of the BINS-SP2 manufacturer Ramenskoye Instrument Making Plant, predicts great demand for the system from military and civilian customers. Three examples per airframe could be installed on civilian aircraft, and two per airframe on warplanes. The system has a service life of 10,000 hours. It can also be used on sea vessels and road transport. Source ato.ru
The aircraft is also fitted with Leninetz Obzor-MS clam pipe navigation and attack pulse-doppler radar, and Mak-UT missile approach warning system infrared (MAWS). It can be upgraded with new equipment for improved reliability.

Propulsion and fuelling
The Tu-95MS combat aircraft is powered by four NK-12MP turboprop engines, driving one eight-bladed, counter-rotating AV-60N auto-feathering propeller each. Manufactured by Kuznetsov Design Bureau, the engine has a take-off power of 15,000bhp and a pressure ratio of 9.7.
NK-12MP (NK-12MA) turboprop engine
The NK-12M developed 8,948 kW (12,000 ehp), uprated in the NK-12MV to 11,033 kW (14,795 ehp) and reaching 11,185 kW (15,000 ehp) in the NK-12MA. The NK-12 remains the most powerful turboprop engine ever built. Only recently the Progress D-27 and Europrop TP400 came somewhat close. It powered the Tupolev Tu-95 bomber and its descendants like the Tu-142 maritime patrol aircraft and the Tupolev Tu-114 airliner (with NK-12MV), which is still the world’s fastest propeller-driven aircraft. It also powered the Antonov An-22 Antei (with NK-12MA), the world’s largest aircraft at the time, and several types of amphibious assault craft, such as the A-90 Orlyonok “Ekranoplan” and the Zubr class LCAC.
