The Burya ("Storm" in Russian; Russian : Буря) was a supersonic, intercontinental cruise missile, developed by the Lavochkin design bureau (chief designer Naum Semyonovich Chernyakov [1] ) under designation La-350 from 1954 until the program cancellation in February 1960. [2] :300 The request for proposal issued by the Soviet government in 1954, [3] called for a cruise missile capable of delivering a nuclear payload to the United States. Analogous developments in the United States were the SM-62 Snark and SM-64 Navaho cruise missiles, particularly the latter, which used parallel technology and had similar performance goals.

Development

The first steps towards development of Burya was the idea of Mstislav Vsevolodovich Keldysh of Keldysh bomber. The Burya was planned as a Mach 3 intercontinental nuclear ramjet cruise missile. The Burya was remarkably advanced for its time, and despite setbacks and several crashes, the vehicle demonstrated a range in excess of 6,000 km with a thermonuclear (hydrogen) bomb-sized payload at speeds greater than Mach 3. The Burya had a two-stage design - the daring concept for an intercontinental missile was the second stage, which was powered by a ramjet engine at its operational speed of Mach 3. This varied from the original Trommsdorff concept of World War II in that no mother aircraft launch preceded the rocket boosted phase. The first stage was a ballistic-rocket-derived booster, which accelerated the Burya to altitude and the speed necessary to ignite its ramjet engine: a ramjet does not operate below subsonic speeds, and to use a hybrid jet-ramjet to broaden its operating speed would have been more complex.[ citation needed ]

Successful tests were achieved after official cancellation of the project, when it continued as a technology demonstration. It was a casualty, like the USAF Navaho, of the greater simplicity and relative invulnerability to interception of intercontinental ballistic missiles. The Burya was an early precursor to the Zvezda and Buran projects. [4]

The guidance system was realized using an inertial system and also a star tracking system. The star tracking system located its position relative to the brightest stars through windows located on the top of stage 2. The star tracking system was more accurate for a long range flight compared to the inertial systems available at that time, even if more complex.[ citation needed ]

Blue Steel (missile) Nuclear stand-off missile

The Avro Blue Steel was a British air-launched, rocket-propelled nuclear armed standoff missile, built to arm the V bomber force. It allowed the bomber to launch the missile against its target while still outside the range of surface-to-air missiles (SAMs). The missile proceeded to the target at speeds up to Mach 3, and would trigger within 100 m of the pre-defined target point.

Cruise missile Guided missile which remains in the atmosphere and flies with approximately constant speed

A cruise missile is a guided missile used against terrestrial targets, that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at supersonic or high subsonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory.

Missile Self-propelled guided weapon system

In military terminology, a missile, also known as a guided missile or guided rocket, is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles, surface-to-air missiles, air-to-air missiles, and anti-satellite weapons.

Ramjet Jet engine designed to operate at supersonic speeds

A ramjet, sometimes referred to as a flying stovepipe or an athodyd, is a form of airbreathing jet engine that uses the engine's forward motion to compress incoming air without an axial compressor or a centrifugal compressor. Because ramjets cannot produce thrust at zero airspeed, they cannot move an aircraft from a standstill. A ramjet-powered vehicle, therefore, requires an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around Mach 3. This type of engine can operate up to speeds of Mach 6.

Ballistic missile Missile that follows a sub-orbital ballistic flightpath

A ballistic missile follows a ballistic trajectory to deliver one or more warheads on a predetermined target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital trajectory.

Project Pluto US nuclear ramjet project, 1957-1964

Project Pluto was a United States government program to develop nuclear-powered ramjet engines for use in cruise missiles. Two experimental engines were tested at the United States Department of Energy Nevada Test Site (NTS) in 1961 and 1964.

Silkworm (missile) Series of Chinese anti-ship missiles

The Shang You or SY-series, and the Hai Ying or HY-series were early Chinese anti-ship cruise missiles. They were derived from the Soviet P-15 Termit missile.

The P-700 Granit is a Soviet and Russian naval anti-ship cruise missile. Its GRAU designation is 3M45, its NATO reporting name SS-N-19 Shipwreck. It comes in surface-to-surface and submarine-launched variants, and can also be used against ground targets.

North American X-10 Experimental missile to test design features of the SM-64 Navaho missile

The North American X-10 was an unmanned technology demonstrator developed by North American Aviation. It was a subscale reusable design that included many of the design features of the SM-64 Navaho missile. The X-10 was similar to the development of the Bell X-9 Shrike project, which was based on features of the GAM-63 RASCAL.

Kh-55 Family of air-launched cruise missiles

The Kh-55 is a Soviet/Russian subsonic air-launched cruise missile, designed by MKB Raduga. It has a range of up to 2,500 km (1,350 nmi) and can carry nuclear warheads. Kh-55 is launched exclusively from bomber aircraft and has spawned a number of conventionally armed variants mainly for tactical use, such as the Kh-65SE and Kh-SD, but only the Kh-101 and Kh-555 appear to have made it into service. Contrary to popular belief, the Kh-55 was not the basis of the submarine- and ground-launched S-10 Granat or RK-55 Relief designed by NPO Novator. The RK-55 is very similar to the air-launched Kh-55 but the Kh-55 has a drop-down turbofan engine and was designed by MKB Raduga. Both have formed the basis of post-Cold-War missiles, in particular the Sizzler which has a supersonic approach phase.

SM-64 Navaho

The North American SM-64 Navaho was a supersonic intercontinental cruise missile project built by North American Aviation (NAA). The final design was capable of delivering a nuclear weapon to the USSR from bases in the US, while cruising at Mach 3 at 60,000 feet (18,000 m) altitude. The missile is named after the Navajo Nation.

AIM-152 AAAM

The AIM-152 AAAM was a long-range air-to-air missile developed by the United States. The program went through a protracted development stage but was never adopted by the United States Navy, due to the ending of the Cold War and the reduction in threat of its perceived primary target, Soviet supersonic bombers. Development was cancelled in 1992.

The Raduga Kh-20 was an air launched cruise missile armed with a thermonuclear warhead which was developed by the Soviet Union during the Cold War. The Kh-20 was designed to be air-launched.

The Buran cruise missile, designation RSS-40, was a Soviet intercontinental cruise missile by Myasishchev capable of carrying a 3,500 kg hydrogen bomb payload. The project was canceled before flight tests began. It is unrelated to the later Buran reusable orbiter.

Lockheed AQM-60 Kingfisher

The AQM-60 Kingfisher, originally designated XQ-5, was a target drone version of the USAF's X-7 ramjet test aircraft built by the Lockheed Corporation. The aircraft was designed by Kelly Johnson, who later created the Lockheed A-12 and its relatives, such as the Lockheed SR-71 Blackbird and Lockheed YF-12.

3M-54 Kalibr Group of Russian missiles

The 3M-54 Kalibr,, also referred to it as 3M54-1 Kalibr, 3M14 Biryuza, , 91R1, 91RT2 is a group of Russian surface ship-, submarine-launched and airborne anti-ship and coastal anti ship (AShM), land attack cruise missiles (LACM) and anti-submarine missiles developed by the Novator Design Bureau (OKB-8). Derived export versions are the 3M54E, 3M54E1, 3M14E, 91RE1, 91RTE2. The 3M54T, 3M54K, 3M54A, 3M54E (3M54TE), 3M54KE and 3M54AE have a second stage that performs a supersonic sprint in the terminal approach to the target, reducing the time that target's defense systems have to react. The 3M54T1, 3M54K1, 3M54A1, 3M54E1 (3M54T/K/AE1) only travel at subsonic speeds, although their range is accordingly greater than those of the supersonic versions.

The Wright XRJ47 was an American ramjet engine developed in the 1950s to help propel the rocket-launched SM-64 Navaho supersonic intercontinental cruise missile. Although the design flight Mach Number was 2.75, a peak flight speed of Mach 3.0, at altitudes up to about 77000 ft, was envisaged. This very large ramjet had a number of design problems, including some difficulty in light-up. Development of the Navaho missile was cancelled along with the ramjet engine in 1957.
