Indigenous Naval Anti-Ship Missile (NASM) series

[porky_kicker]

NASM-LR (long range)?.. Meant for Teddy maybe... Certainly longer than regular NASM & the booster in that isn't a seperate module, from what I can tell.

Only 2 versions of NASM are intended and planned

NASM-SR short range
NASM-MR medium range

Requirements of longer range sub sonic anti ship missile will be catered by ITCM / SLCM / ALCM and DSCM ( which is supposed to a sub sonic missile with supersonic terminal stage , unfortunately no information regarding it )

Naval Anti-Ship Missile Short Range (NASM-SR)

DRDO also is developing Naval AntiShipping Missile Short Range (NASM-SR) with a 55 km range for use from Sea King helicopters and eventually equip the MH-60R helicopters. The existence of the Naval Anti-Ship Missile NASM SR was revealed in 2018 in the Lok Sabha. Raksha Mantri Nirmala Sitharaman named this in the list of DRDO developments and those at other Indian institutions over the past three years (January 2016-December 2018). The project has since been referred to by its acronym NASM-SR. The document shared by Sitharaman showed a fund allocation of Rs 434.06 crore for the project. Initial details were unveiled at the DefExpo 2020. This project is possibly being developed for a number of platforms, having different ranges. ‘SR’, or Short Range, means that development of other longer range versions is expected as well.

Further details of the new weapon emerged at DefExpo 2020, where the DRDO showed schematics of the NASM-SR. The missile tested on 18 May 2022 appeared to be visually similar to the NASM-SR. The data shared by the DRDO showed the proposed weapon had a weight of 380kg and a range of up to 55km and was meant for launch from helicopters. The DRDO claimed the weapon would travel at a speed of 0.8 Mach (slower than the speed of sound) and would have an imaging infra-red seeker, which would home in on the heat emissions of its targets.

The weapon would have a warhead of 100kg, capable of sinking patrol boats and damaging larger warships. The NASM-SR, on approach to its target, can cruise at just 5metres above sea level, making it difficult for enemy radars to detect and track and shoot down with surface-to-air missiles or guns. This low-level capability of anti-ship missiles is known as sea skimming.

According to DRDO, the NASM-SR will be a 380 kg projectile with a maximum range of 55 km and used initially with Indian Navy Sea King helicopters, replacing the earlier Sea Eagle missiles. As the Sea King itself is approaching the end of its service life, it may be expected that the new indigenous missile will be in service with future helicopters of the Navy.

The Indian Navy procured MH-60R helicopters for multi-role purposes and these will be equipped with Kongsberg Naval Strike Missile. Further, for the Indian Navy’s IMRH acquisition, MBDA pitched its Sea Venom which has a range of 25 km and also the Marte ER which can reach more than 100 km.

The NASM SR could certainly be considered for these potent platforms. The long range version of the NASM may have a range excess of 150 km, enabling engagement of hostile targets from stand-off distances. At the DRDO exhibit at Aero India 2019 were several posters of a one-tonne class medium range air launched cruise missile, though little was revealed about this unnamed stealth missile.

An indigenously developed Naval Anti-Ship Missile was successfully test-fired for the first time from a naval helicopter from Integrated Test Range (ITR), Chandipur off Odisha coast on May 18. It is the first indigenous air-launched anti-ship missile system for the Indian Navy, Defence Research and Development Organisation (DRDO) said in a statement. “The missile followed the desired sea skimming trajectory and reached the designated target with high degree of accuracy, validating the control, guidance and mission algorithms,” DRDO said.

The new missile employed several new technologies, including a proprietary launcher, developed in India, for the Sea King. The missile guidance system includes state-of-the-art navigation system and integrated avionics. All the sub-systems performed satisfactorily and the sensors deployed across the test range and near impact point tracked the missile trajectory and captured all the events, it stated.

The test was carried out from a Seaking-42B helicopter. The missile employed many new technologies, including an indigenously developed launcher for the helicopter, and the missile guidance system includes a state-of-the-art navigation system and integrated avionics, according to DRDO. The mission met all its objectives, it said.
Union Defense Minister Rajnath Singh has lauded DOTO scientists and sailors for successfully testing interceptor missiles. He said India had reached new heights in domestic production and missile development. Similarly, DOTO Chairman Satish Reddy also expressed his appreciation. In an interview with a senior naval officer, he said, ‘This test plays an important role in achieving self-sufficiency in missile technology. The test also reaffirms the Navy’s commitment to domestication.

Naval Anti-Ship Missile-Short Range (NASM-SR)

In news– Defence Research and Development Organisation (DRDO) and Indian Navy successfully conducted maiden flight-test of indigenously-developed Naval Anti-Ship Missile launched from a Naval Helicopter from Integrated Test Range (ITR), Chandipur off the coast of Odisha.
About Naval Anti-Ship Missile-

• Developed by the DRDO,the first time its development was revealed to the general public was in 2018 when then Defence Minister Nirmala Sitharaman made a reference to it in Parliament. Later, it was also part of the display at the 2020 Defence Exposition held in Lucknow.
• It has a range of 55 km and weighs 385 kg. This missile will replace the Sea Eagle missiles which are currently in use with the Navy.
• With the Sea King helicopters too being phased out, it is expected that the NASM-SR will be used with the new MH-60R multi-role helicopters, which are being inducted into the Navy.
• It carries a warhead of 100 kg and has subsonic capabilities, which means that it flies below the speed of sound at 0.8 Mach. The sub-sonic flight speed makes it difficult for the naval vessels on target to detect it.
• It has a launch altitude of maximum of 3 km and can skim 5 metres above sea level when on final approach to the target.
• The NASM-SR can also be fired from the shore to target vessels in the sea.
• This kind of land-based missile launch capability was shown by the Ukrainian military recently when they used a anti-ship cruise missile to sink the Russian ship Moskva.
• The NASM-SR is very effective against smaller vessels like patrol boats and can also cause widespread damage on larger vessels.
• It has been proven in modern naval conflict that a modest strike by a missile can still sink a ship because of the implosion caused by on-board fuel and ammunition.
• Also, the lighter size of the missile makes it easier to be carried by helicopters and in turn provides Naval Commanders with more options to choose from in the tactical battlefield on the seas.
