Cruise missiles


Nirbhay

Nirbhay  is a long range, first subsonic cruise missile being developed in India. The missile will have a range of 1,000 km. Nirbhay will be capable of being launched from multiple platforms on land, sea and air. The missile will be able of carrying 24 different types of warheads and shall be inducted into Indian Navy, Army, and Air Force. In particular, Nirbhay will be adapted for the Indo/Russian Su-30MKI.It was reported in May 2010 that the missile will be capable of carrying nuclear warheads.

Development
The missile is being developed by the Aeronautical Development Establishment, a division of DRDO and after finalizing the design, the technology required for the missile is being developed. The first test flight of the missile is expected in the year 2012. It was likely to be test-fired in October, 2012. But the launch, earlier planned for October, has now been shifted to December owing to the changes being made to the launcher. It is being built by R&D Engineers, Pune, a specialised arm of DRDO. Nirbhay will be a terrain hugging, stealth missile capable of delivering 24 different types of warheads depending on mission requirements and will use an inertial navigation system for guidance. Nirbhay will supplement Brahmos in the sense that it would enable delivery of warheads farther than the 290 km range of Brahmos.
3M-54 Klub

The Russian 3M-54 Klub is a multi-role missile system developed by the Novator Design Bureau(OKB-8). Its NATO reporting name is SS-N-27. Both submarine and surface ship launched versions exist. The system is designed to accept various warheads, allowing its use against surface and subsurface naval combatants along with static land targets. In one variant, the 3M-54E (Sizzler), the final stage makes a supersonic 'sprint' to its target, reducing the time the target's defense systems have to react. The 3M-54E1 subsonic missile is roughly comparable to both the American Tomahawk cruise missile and the ASROC missile but is smaller and has a shorter range.
Design
The missile is a modular system with 5 different variants: two anti-shipping variants, one land attack variant, and two anti-submarine variants. The missile is designed to share common components between the surface and sub-launched variants with the only difference being the design of the missile launchers and the containers. An air-launched version is believed to be in development.

Sizzler' flight
The Sizzler variant (3M-54E) flies at subsonic speeds while going supersonic as it nears its target. It is also believed to be able to perform very high angled defensive maneuvers in contrast to the common linear flight path of other anti-ship cruise missiles.
Variants
There are two major launching vehicles: the Klub-S, designed for launch from submarines, and the Klub-N, designed for launch from surface ships. These two launchers can be equipped by the following warhead and guidance combinations:
3M-54E - Anti-shipping variant, Basic length 8.22 m, with a 200 kg warhead. Range is 200 km. Sea-skimmer with supersonic terminal speed and flight altitude of 15 feet (4.6 m) at final stage(2.9 mach).
3M-54E1 - Anti-shipping variant, Basic length 6.2 m, with a 400 kg warhead. Range is 300 km. Sea-skimmer with subsonic terminal speed(0.8 mach). Allegedly capable of disabling or even sinking an aircraft carrier.
3M-14E - Inertial guidance land attack variant. Basic length 6.2 m, with a 400 kg warhead. Range is 275 km. Subsonic terminal speed(0.8 mach).
91RE1 - Submarine launched anti-submarine variant, with an anti-submarine torpedo. Basic length 8.0 m, with a range of 50 km. Supersonic speed. The torpedo has a warhead weight of 76 kg. This, along with the 91RE2, are similar to the American ASROC/SUBROC missile/torpedo system. Follows a ballistic path into the surface, speed is Mach 2.5.

91RE2 - Ballistically launched anti-submarine variant, with an anti-submarine torpedo. Basic length 6.5 m, with a range of 40 km Supersonic speed. The torpedo has a warhead weight of 76 kg. For surface ship use only. The lightest of all variants, with a launch weight of 1300 kg. Speed is Mach 2.
Launch Platforms
The Russian Kilo class submarine is the primary launch platform for the missile. The future Russian Lada class submarine and its variants should also be able to launch the missile. The Indian Talwar class frigate is another primary shipborne launch platform for the missile. The Akula class submarine and the new Yasen class can also launch this missile. The new Russian Admiral Sergei Gorshkov class frigates and the second batch of Steregushchy class corvettes use the same UKSK VLS as Talwar class frigates, and thus would be able to carry these missiles as well.
It is also believed by some analysts that an air launched variant will be developed to arm the Tu-142s currently in service with both the Russian and Indian Navy, and it is also anticipated that the Tu-22M3 operated by the Indian Navy will also be equipped with the missile. A truck mounted version is also planned for development by the Novator Design Bureau.
A Klub-K variant, which launches from commercial-appearing shipping container mounted on a truck, train, or merchant vessel, was advertised in 2010 and was shown for the first time at the MAKS 2011 airshow.

P-270 Moskit
The P-270 Moskit (Russian: П-270 «Москит»; English: Mosquito) is a Russian supersonic ramjet powered cruise missile. Its GRAU designation is 3M80, and its NATO reporting name is SS-N-22 Sunburn. The missile system was designed by the Raduga Design Bureau during the 1970s as a follow up to the "SS-N-9 Siren". The Moskit was originally designed to be ship launched, but variants have been adapted to be launched from land (modified trucks), underwater (submarines) and air (reportedly the Sukhoi Su-33, a naval variant of the Sukhoi Su-27). The missile can carry conventional and nuclear warheads.
The exact classification of the missile is unknown, with varying types reported. This uncertainty is due to the secrecy surrounding an active military weapon. The Moskit is one of the missiles known by the NATO codename SS-N-22 Sunburn. It reaches a speed of Mach 3 at high altitude and Mach 2.2 at low-altitude. This speed is triple the speed of the subsonic American Harpoon. When slower missiles, like the Harpoon or the French Exocet are used, the maximum theoretical response time for the defending ship is 120 to 150 seconds. This long response time provides time to launch countermeasures and employ jamming before deploying "hard" defense tactics such as launching missiles and using quick-firing artillery. But the high speed of the 3M82 "Mosquito" missiles reduce the maximum theoretical response time for the defending ship to 25 to 30 seconds. This short response time makes jamming and countermeasures very difficult, and firing missiles and quick-firing artillery even more difficult. The Moskit was designed to be employed against smaller NATO naval groups in the Baltic Sea (Danish and German) and the Black Sea (Turkish) and non-NATO vessels in the Pacific (Japanese, South Korean, etc.), and to defend the Russian mainland against NATO amphibious assault.
Variants of the missile have been designated 3M80M, 3M82 (Moskit M).[3] The P-270 designation is believed to be the initial product codename for the class of missile, with the Russian Ministry of Defense GRAU indices (starting with 3M) designating the exact variant of the missile. The 3M80 was its original model. The 3M80M model (also termed 3M80E for export) was a 1984 longer range version of the missile, with the latest version with the longest range being the 3M82 Moskit M. The ASM-MMS / Kh-41 variant is the air launched version of the missile.The missile has been purchased by the People's Liberation Army Navy (China) and India.
BRAHMOS

Origins
The BrahMos has been developed as a joint venture between the Defence Research and Development Organization (DRDO) of India and the Federal State Unitary Enterprise NPO Mashinostroyenia (NPOM) of Russia under BrahMos Aerospace. The missile is named after two rivers, the Brahmaputra and the Moskva
Since late 2004, the missile has undergone several tests from variety of platforms including a land based test from the Pokhran range in the desert, in which the 'S' manueuver at Mach 2.8 was demonstrated for the Indian Army and a launch in which the land attack capability from sea was demonstrated.
Keltec (now known as BrahMos Aerospace Trivandrum Ltd or BATL), an Indian state owned firm was acquired by Brahmos Corporation in 2008. Approximately 1,500 crore (US$283.5 million) will be invested in the facility to make Brahmos components and integrate the missile systems. This was necessitated by the increased order book of the missile system, with orders having been placed by both the Indian Army and Navy. Tested at: Pokhran

Description

BrahMos claims to have the capability of attacking surface targets by flying as low as 10 metres in altitude. It can gain a speed of Mach 2.8, and has a maximum range of 290 km. The ship-launched and land-based missiles can carry a 200 kg warhead, whereas the aircraft-launched variant (BrahMos A) can carry a 300 kg warhead. It has a two-stage propulsion system, with a solid-propellant rocket for initial acceleration and a liquid-fuelled ramjet responsible for sustained supersonic cruise. Air-breathing ramjet propulsion is much more fuel-efficient than rocket propulsion, giving the BrahMos a longer range than a pure rocket-powered missile would achieve.
The high speed of the BrahMos likely gives it better target-penetration characteristics than lighter subsonic cruise-missiles such as the Tomahawk. Being twice as heavy and almost four times faster than the Tomahawk, the BrahMos has almost 9 times the initial kinetic energy of a Tomahawk missile (although it pays for this by having only 3/5 the payload and a fraction of the range despite weighing twice as much, suggesting a different tactical paradigm to achieve the objective). Its 2.8 mach speed means that it cannot be intercepted by some existing missile defence system and its precision makes it lethal to water targets.
Although BrahMos was primarily an anti-ship missile, the Brahmos Block III can also engage land based targets. It can be launched either in a vertical or inclined position and is capable of covering targets over a 360 degree horizon. The BrahMos missile has an identical configuration for land, sea, and sub-sea platforms.[citation needed] The air-launched version has a smaller booster and additional tail fins for added stability during launch. The BrahMos is currently being configured for aerial deployment with the Su-30MKI as its carrier. On 5 September 2010 BrahMos created a record for the first supersonic steep dive. Brahmos was first test fired on 12 June 2001 from the Integrated Test Range (ITR), Chandipur in a vertical launch configuration.
Brahmos Block III+ was test fired from a Mobile Autonomous Launcher on 2 December 2010 with a new advanced guidance scheme incorporating large scale manoeuvres at multiple points and a steep dive from high altitude with precision strike. Brahmos completed all manoeuvres, hitting the target precisely. On 12 August 2011 it was test fired by ground forces and met all mission parameters. The BrahMos cruise missile was successfully test fired by an Indian Army unit on Sunday, 4 March 2012 at the Pokharan range in Jaisalmer to operationalise the second regiment of the weapon system in the Indian Army.
The Indian Navy on 7 October 2012 morning successfully test-fired BrahMos from a guided missile frigate INS Teg. This new highly manoeuvrable version is fitted with advanced satellite navigation systems turning it into a "super-rocket" capable of hitting targets over 300–500 km from sea, land and air launchers, and capable of carrying a nuclear warhead.

BrahMos-2
BrahMos-2 is a stealth hypersonic cruise missile currently under development and has a range of 290 km. The range of Brahmos-2 has been regulated to 290 km as Russia is a signatory of the Missile Technology Control Regime (MTCR) which does not allow it to help other countries to develop missiles with ranges above 300 kilometres. With a speed of Mach 7 it will have a speed double the speed of the current Brahmos-1, and it has accordingly been branded as the fastest hypersonic missile in the world
BrahMos II land variant design has been completed and 4 surface to surface variants are ready to be tested. Rest of the variants will be tested in the successive years of 2012–13, design is projected to be completed by October 2011 and will arm the Project 15B destroyers of the Indian Navy. In Russian navy project 21956 Destroyers are most likely to be equipped with BrahMos II.[82]

Akash
Akash  is a medium-range mobile surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO), Ordnance Factories Board and Bharat Electronics Limited (BEL) in India. The missile system can target aircraft up to 30 km away, at altitudes up to 18,000 m. A nuclear warhead could potentially give the missile the capability to destroy both aircraft and warheads from ballistic missiles. It is in operational service with the Indian Army and the Indian Air Force.
The first test flight of Akash missile was conducted in 1990, with development flights up to March 1997.
Two Akash missiles intercepted two fast moving targets in simultaneous engagement mode in 2005. 3-D Central Acquisition Radar (3D-CAR) group mode performance is also fully established.
Along with India, a limited number of other countries including the US, Russia, Japan, Israel, and some EU countries have developed operational multitarget-handling surface-to-air missile systems. With the successful user trials of Akash, India has validated the technology and operational efficacy of this missile system. This system is claimed to be more accurate than the MIM-104 Patriot as it has thrust during the entire course of its flight compared to the Patriot that has thrust only for the first 12 seconds, after which the missile coasts, thus making it less accurate. Apart from that the Akash can be launched from static or mobile platforms, including a battle tank. The Akash Missile Development cost of  1,000crore ($200 million), including the project sanction of  600 crore ($120 million), is 8-10 times lower than the cost of similar system developments in other countries. Akash has certain unique characteristics like mobility, all-the-way-powered flight till target interception, multiple target handling, digitally-coded command guidance and fully automatic operation.
As reported on June 11, 2010, Akash Mk-II version has begun development and will be ready for a first flight in 24 months. The Akash Mk-II will be a longer-range, faster and more accurate SAM. The missile will have an intercept range of 30–35 km and increase in the accuracy of the missile's guidance system and the fire control system.
