INS Anvesh

INS Anvesh is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand INS Anvesh rather than just read about it. In short: INS Anvesh (Hindi: अन्वेष; lit. Search), is a missile range instrumentation ship (also termed as a Floating Test Range (FTR)) built for the Indian Navy.

Key takeaways

INS Anvesh belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect INS Anvesh to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of INS Anvesh from memory before moving on to harder problems.

Reference excerpt

INS Anvesh (Hindi: अन्वेष; lit. Search), is a missile range instrumentation ship (also termed as a Floating Test Range (FTR)) built for the Indian Navy. The ship is a project of the Defence Research and Development Organisation (DRDO) and built by Cochin Shipyard Limited (CSL). The ship was conceived to serve as a sea-based platform for India's ballistic missile defence program and consists of 4 Ship Launch System (SLS) VLS for the same purpose. The Phase II of the BMD envisages intercepting and destroying enemy missile up to range of 5,000 kilometers by kinetic force with the FTR allowing live testing of the interdictor missiles and not computer simulations.

Design INS Anvesh was designed by Vik-Sandvik Design India Pvt Ltd ("VSDI"). It has a length of 118.4 m, 20 m width and 7.1 m draft and having a steel weight of approximately 3,900 tons. The ship incorporates LRDE Long-Range Multi Function Radar (LRMFR) which will be used by Indian naval ships in future as Fire control radars for Ballistic Missile Defence. The 6 metre Active Antenna Array Unit (AAAU) for the radar was built by Astra Microwave Products Ltd. the first of which would be delivered in latter half of 2023. The LRMFR is an S-band radar system which is intended to replace the EL/M-2248 MF-STAR radar used by the Indian Navy as the primary naval radar of the next generation of naval ships. The functions of LRMFR includes acting as Fire Control Radar (FCR) for surface-to-air missile systems onboard ships and to track ballistic missiles. The vessel equipped with electro-optical missile tracking, S-band radar tracking, telemetry devices apart from a launch pad, control and mission control center, for testing its Phase II of Ballistic Missile Defence (BMD) interceptor missiles. The Phase II of the BMD envisages intercepting and destroying enemy missile up to range of 5,000 kilometers by kinetic force with the FTR allowing live testing of the interdictor missiles and not computer simulations. The missile launch system consists of 4 Ship Launching Systems (SLS) in the aft section which rests at 0° when not in used but the alignment is changed to 90° during test launches. The SLS was developed by Electropneumatics & Hydraulics Pvt Ltd. The ship has other specialised systems like damping tanks, missile integration and checkout bay, data processing room and mission control center. It is also equipped with a 15 ton crane and A-frame for cargo handling in the aft section. It is also designed to test radars, sonars, telemetry equipment and propulsion. The configuration of the installed power generation is Integrated Full Electric Propulsion (IFEP). The output is 14 MW which is produced by diesel generators powering steerable contra-rotating propulsion thrusters.

Construction The construction of the then-DRDO Technology Demonstration Vessel was awarded to the Cochin Shipyard Limited (CSL) by the DRDO, India's premier agency for R&D in defence, in August 2015. The original contract for the construction of the vessel was with Bharati Shipyard, but time overruns forced by the yard's poor finances led to termination of the contract. Subsequently, the Cochin Shipyard won the bid to execute this project. Steel plate cutting of the vessel was started on 10 August 2016. Dr. S Christopher, chairman, DRDO and Secretary, Department of Defence R&D, launched the mega block assembly of hull blocks of the ship (Ship No. 20) on 27 January 2016 at CSL. The ceremonial event of commencement of Mega Block Assembly of hull blocks of Ship No. 20, the Technology Demonstration Vessel, being built for the Defence Research & Development Organisation (DRDO), Government of India was held on 27 January 2017 at CSL. It was reported that the ship will commence the sea trial in September 2021 and will be commissioned by the end of 2021.

Commissioning The ship had been quietly commissioned by National Security Advisor Ajit Doval on 11 March 2022. A photo of the commissioning ceremony has been made public for the first time in the Indian Navy Song 2022: 'Hum Taiyyar hain'.

Service history The first missile test onboard INS Anvesh was carried out on 21 April 2023 off the Odisha coast. The missile tested was an Advanced Air Defence (AAD) or Ashwin Ballistic Missile Interceptor. The missile included India in the list of countries who have developed naval BMD systems.She participated at the International Fleet Review 2026 held at Visakapatanam.

Worked examples

Example 1 — a first encounter with INS Anvesh

Start with the simplest possible case. Write down what INS Anvesh claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to INS Anvesh before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about INS Anvesh ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of INS Anvesh

In research: INS Anvesh appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses INS Anvesh in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: INS Anvesh is common in secondary-school and first-year university syllabi. It links to neighbouring topics Auxiliary ships of the Indian Navy, Defence Research and Development Organisation, Maritime vessels related to spaceflight, so understanding it makes those chapters shorter.
In everyday life: Look for INS Anvesh outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
