INS Dhruv (A40) is a research vessel and missile range instrumentation ship built by India's Hindustan Shipyard Limited (HSL). The ship was earlier only known by its shipyard designated yard number as VC-11184. [3]

Contents

The ship can gather electronic intelligence and will be used to track missile and satellites to aid India's strategic weapons and anti-ballistic missiles. It will be jointly operated by National Technical Research Organisation (NTRO), Defence Research and Development Organisation (DRDO) and the Indian Navy. The development span of ships has remained largely secretive with little information in public domain. The ship reportedly started sea trials in early 2019, [4] and entered service in October 2020 without a public commissioning ceremony. [2] The ship was officially commissioned on 10 September 2021 at Visakhapatnam in the presence of senior officials from the Indian Navy, the DRDO and the NTRO. [5]

Development

The purpose of the ship is to support the development of India's strategic weapons and the Indian Ballistic Missile Defence Programme. The ship can also track strategic missiles and satellites. [6] In addition, it can also gather electronic intelligence. The keel of the ship was laid on 30 June 2014 at Hindustan Shipyard Limited. [7] It is being built under a classified and confidential programme which is directly under the control of the Prime Minister's Office and the National Security Advisor, similar to the Advanced Technology Vessel (ATV) programme of the Indian Navy. [8] [7] The ship started harbour trials in July 2018 and was expected to undergo sea trials by the end of 2018. [9] As of March 2019, sea trials were ongoing. [10] The ship was delivered to the Indian Navy in October 2020 quietly [2] meanwhile official induction expected on first half of 2021. [6]

Design and description

The ship cost around ₹ 1,500 crore (equivalent to ₹24 billionorUS$290 million in 2023) and has been designed in India by Vik Sandvik Design India. [7] It has a displacement of more than 10,000 tonnes, length of 175 metre, beam of 22 metre, draught of 6 metre and can attain a speed of 21 knots. It is powered by two imported 9,000 kilowatt combined diesel and diesel (CODAD) configuration engines and three 1200 kilowatt auxiliary generators. [8] [7]

The ship will be fitted with a primary X band and a secondary S band active electronically scanned array (AESA) radar. In addition, it has a long open deck with ample space for installing multiple missile tracking antennas. It will have a crew complement of 300 personnel and will carry a single helicopter. [8] The ship will also have a special team from National Technical Research Organisation on board. [11]

Commissioning

The ship was commissioned by NSA Ajit Doval on 10 September 2021 in Visakhapatnam. [12] The ship will be jointly operated by National Technical Research Organisation (NTRO), Defence Research and Development Organisation (DRDO) and the Indian Navy. [6]

INS Dhruv will be under Strategic Forces Command (SFC) and based in Eastern Naval Command of Indian Navy. [13]

Service

INS Dhruv had its first mission deployment to support Mission Divyastra, the planned test on an Agni-V missile with MIRV technologies. It successfully tracked the test flight on March 11 2024. The project directors will examine the trajectory and other variables of the missile as recorded by the Indian ballistic missile tracker INS Dhruv to make any operational changes if required. [14]

Agni-V is a land based nuclear MIRV-capable Intercontinental Ballistic Missile (ICBM) developed by the Defence Research and Development Organisation (DRDO) of India. The missile has a range of more than 7,000 km. It is a three-stage, road-mobile, canisterised and solid-fuelled ballistic missile. It is one of the fastest missile in the world reaching the speed up to 29,400 km/hr.

Swordfish is an Indian active electronically scanned array (AESA) long-range tracking radar specifically developed to counter ballistic missile threat. It will be a part of the Indian Ballistic Missile Defense Programme. First testing of this radar was in March 2009. Main aim of the test was to validate the capabilities of the Swordfish Long Range Tracking Radar (LRTR). "The missile to be hit will be fired from a longer distance than it was in the earlier test. DRDO tested whether the radar could track the incoming missile from that distance or not," said a member of the project. This radar is an acknowledged derivative of the Israeli EL/M-2080 Green Pine long range radar, which is the critical component of that country's Arrow missile defense system. However, it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies. It is also more powerful than the base Green Pine system and was developed to meet India's specific BMD needs.

The K family of missiles, is a family of submarine-launched ballistic missiles (SLBM) developed by India to boost its second strike abilities and thus augment its nuclear deterrence. Information about this family of missiles has mostly been kept classified. It is reported that 'K missiles' are faster, lighter and stealthier than their Agni missile counterparts. High Energy Materials Research Laboratory (HEMRL) developed a new formulation of composite propellant that is more efficient and provide greater thrust compare to Agni missile series. The objective behind the development is to make K missile family faster and lighter without compromising on operational range.

India has studied, produced and used various strategic and tactical missile systems since its independence. Decades long projects have realised development of all types of missile systems including ballistic, cruise, anti-ship, air-defence, air-to-air and anti-missile systems. India is one of seven countries in the world with intercontinental ballistic missiles (ICBMs) and one of four countries with anti-ballistic missile systems. Since 2016, India has been a member of Missile Technology Control Regime (MTCR).
