Development edit

Since 1980s, the Indian Navy has been using Sea Eagle anti-ship missile on its Westland Sea King Mk.42B multipurpose helicopter. The NASM-SR is intended as a replacement for the Sea Eagle missile which restricted flight range and increased take-off weight. The development of NASM-SR was made public for the first time in 2018 by the then Minister of Defence Nirmala Sitharaman. Fund of ₹434.06 crore for the development was also allocated in the same year.[4] The design and specifications of the new missile was revealed at the DefExpo 2020. The specification showed Mach 0.8 capable air launched anti-ship missile with a range of 55 km. The missile has an Imaging Infra-Red (IIR) seeker immune to jamming, state-of-the-art navigation system and integrated avionics.[4]

The NASM-SR can be easily adapted to launch from ships and land-based vehicles. DRDO is speculated to be developing a long range version of it for attacking land targets.[4] As the Sea King Helicopters are being phased out, the NASM-SR will be equipped on Indian Navy's newly acquired MH-60R naval helicopters.[5]

Testing edit

Maiden flight test of NASM-SR

Indian Navy successfully carried out the first test of the missile from a Sea King Mk.42B helicopter on 18 May 2022.[6] On maiden test firing, NASM-SR demonstrated its sea skimming capability and approaches the target at 5m above the sea level.[7] The maiden test was successful, and the missile is said to have reached the designated target with high degree of accuracy. It validated the control, guidance and mission algorithms.[8]

DRDO conducted second successful trial of NASM-SR on 21 November 2023 in collaboration with Indian Navy.[9]
