Two contracts were signed in New Delhi on 15 October 2026, worth about ₹4,106 crore together. One buys the Indian Air Force a communication satellite of its own. The other buys the Indian Navy a stock of heavy weight torpedoes. They look like an ordinary procurement announcement, and in one sense they are. What makes them worth a candidate's attention is the identity of the two sellers, because neither is the company most people would guess.
The two contracts, exactly as signed
The GSAT-7C contract is worth ₹2,563 crore and was signed with NewSpace India Limited, Bengaluru. The Ministry describes the satellite as indigenously designed, developed and manufactured, intended to give the Air Force secure, resilient and seamless communication across its assets.
The Varunastra contract is worth ₹1,543 crore and was signed with Bharat Dynamics Limited, Hyderabad. Varunastra is an indigenous ship-launched anti-submarine torpedo, developed by the Naval Science and Technological Laboratory (NSTL).
Both were signed in the presence of the Additional Secretary and Director General (Acquisition) in the Department of Defence, Shri A Anbarasu. That detail is not decoration — the DG (Acquisition) is the officer through whom capital acquisition contracts are concluded, and naming the office tells you this is capital procurement rather than a revenue purchase.
The seller nobody expects: NewSpace India Limited
A defence satellite contract signed with a company under the Department of Space, not the Department of Defence Production, is the single most instructive fact here.
NewSpace India Limited (NSIL) was incorporated on 6 March 2019 under the Companies Act, 2013. It is a wholly government-owned Central Public Sector Enterprise under the administrative control of the Department of Space, headquartered on the ISRO campus in Bengaluru, and it functions as ISRO's commercial arm. In February 2020 the Department of Public Enterprises classified it as a Schedule 'A' enterprise.
Its mandate matters more than its date of birth. Following the space-sector reforms of June 2020, NSIL was given responsibility for end-to-end commercial space activity — building and operating satellites, launching Indian and foreign payloads, supplying satellite communication and Earth-observation services, and transferring ISRO technology to Indian industry. The phrase used for the shift is demand-driven: missions are now built to a customer's requirement rather than scheduled from ISRO's own programme. NSIL is also the nodal agency for PSLV production through an industry consortium, under a Government-Owned Contractor-Operated arrangement that uses existing ISRO facilities.
So when the Air Force buys a satellite, the counterparty is a space CPSE operating on a commercial footing, and ISRO's role shifts from programme owner to technology source. That is the structural point, and it is the kind of institutional detail that separates a prepared answer from a recited one.
Why the Air Force wants its own satellite
India's dedicated military satellites have arrived one service at a time.
GSAT-7, named Rukmini, was launched on 30 August 2013 aboard an Ariane-5 from Kourou, French Guiana, at a reported cost of about ₹185 crore. It was India's first dedicated defence satellite and it belongs to the Navy, carrying UHF, C-band and Ku-band payloads to link shore establishments, surface ships, submarines and aircraft over a wide maritime area. For a navy whose operating area runs thousands of kilometres from the coast, satellite communication is not a convenience; it is the only way a dispersed fleet stays a fleet. The same orbit that makes this possible — a satellite parked where it appears stationary over one patch of earth — is what gives geostationary imaging its persistent stare.
GSAT-7A followed in December 2018, launched on GSLV-F11 — the seventh flight of the GSLV Mk-II with the indigenous cryogenic upper stage. Weighing roughly 2,250 kg and operating in Ku-band with a design life of about eight years, it was built principally for the Air Force, and is widely nicknamed the Angry Bird. Its value lies in networking: interlinking ground radar stations, airbases and airborne early warning and control aircraft so that a picture built in one place can be used in another.
GSAT-7C is the next step in that line. The Defence Acquisition Council granted Acceptance of Necessity for it on 23 November 2021, at an indicated value of about ₹2,236 crore. The contract signed on 15 October 2026 is worth ₹2,563 crore.
Two things follow from putting those numbers side by side, and both are examinable.
First, the gap is nearly five years. An Acceptance of Necessity is not a contract. It is the Defence Acquisition Council's finding that a capability is needed and that the proposed category of procurement is appropriate. What comes after it — the Request for Proposal, technical and field evaluation, staff evaluation, the Contract Negotiation Committee, and finally approval by the competent financial authority — is where the years go. The scale of what sits in that pipeline is easy to underestimate: the Defence Acquisition Council cleared ₹1.10 lakh crore of proposals in a single sitting in September, none of which were purchases on that day. Candidates who treat an AoN headline as a purchase are making a mistake the acquisition system itself is designed to prevent.
Second, the value rose by roughly 15% between the approval and the signature. Nothing sinister follows from that; configurations change and costs move over five years. But it is a useful corrective to the habit of quoting an AoN figure as though it were the price paid.
The torpedo, and what "heavy weight" means
Varunastra entered Indian Navy service in 2016, with the first unit handed over at the end of June that year. It was designed by NSTL, Visakhapatnam, a DRDO laboratory, and is manufactured by Bharat Dynamics Limited. In June 2019, BDL signed a contract for 63 units worth about ₹1,187.82 crore; the contract signed now, at ₹1,543 crore, continues that production line.
Published specifications vary between sources, and a careful candidate should treat them as approximate rather than memorise a single figure. The commonly cited values are a mass of about 1,500 kg, a length of roughly 7.78 m, a diameter of 533 mm, a high-explosive warhead of about 250 kg, propulsion by silver oxide-zinc batteries, an operating range in the region of 40–50 km, and a maximum depth variously given between 400 m and 600 m. Guidance combines wire guidance with active and passive acoustic homing.
The 533 mm diameter is the fact worth holding, because it is what the word heavy weight actually means. Torpedoes divide into two broad classes:
- Lightweight torpedoes, around 324 mm, launched from ships, helicopters and maritime patrol aircraft. They are small enough to be carried in numbers by an aircraft, and they exist to attack a submarine quickly once it has been detected.
- Heavy weight torpedoes, around 533 mm, launched from surface ships and submarines. They carry a far larger warhead, run much further, and are the weapon intended to actually sink a major target.
Anti-submarine warfare is layered, and each layer has a different weapon. A maritime patrol aircraft or a shipborne helicopter prosecutes a distant contact with a lightweight torpedo. A rocket-assisted system puts a torpedo into the water at a stand-off distance. The heavy weight torpedo is what a warship or submarine fires when the geometry is right and the intent is to destroy. Varunastra sits in that last category, which is why a stock of them matters more than the unit price suggests.
Two public sector companies, two different reasons
It is tempting to read both contracts as the same story — Indian equipment from Indian firms. The reasoning is different in each case, and the difference is the better answer.
With BDL, the state is buying production capacity for a design the state already owns. NSTL designed Varunastra; BDL builds it. The money buys throughput on an existing line, and the technology question was settled a decade ago. It is the same logic as the SAAW glide-bomb contract placed with BDL in September under the Buy (Indian-IDDM) category.
With NSIL, the state is buying a capability from an arm of its own space programme on commercial terms. ISRO's expertise is the input, but the contracting entity is a company that is expected to behave like a supplier — to quote, to deliver against a contract, and to carry the commercial risk. That is a deliberate restructuring of how India's space capability reaches other arms of government, and the defence sector is now one of its customers.
Both contracts were framed by the Ministry as advancing domestic defence manufacturing in line with Aatmanirbhar Bharat and Make in India. That framing is accurate here, but it is applied to almost every contract announcement, so it carries little information on its own. The informative detail is always the counterparty and the category of procurement — which is where the first marks are.
How to read a procurement announcement
Three questions answer most of what an examiner can ask about a contract of this kind.
Who is the buyer, and who is the seller? A Ministry of Defence contract with a Department of Space company is unusual and tells you something about how the capability is being sourced. A contract with a Defence PSU for an item designed by a DRDO laboratory tells you the design and the manufacture sit in different institutions.
What stage is this? An Acceptance of Necessity, a Request for Proposal, a contract and a delivery are four different events, often separated by years. Press coverage frequently merges them.
What does the money actually buy? ₹1,543 crore for torpedoes buys a quantity of an existing weapon. ₹2,563 crore for a satellite buys design, build, launch and the ground segment of something that does not yet exist. The two numbers are not the same kind of number at all.

📋 How this gets asked (PYQ pattern)
Defence procurement appears in the NDA General Ability paper in a narrow and predictable set of forms, and this pair of contracts supplies all of them.
The first is the organisation question. Which laboratory developed a given system, and which company manufactures it. The design-manufacture split — NSTL designs, BDL builds — is the standard trap, and the paper has used it for the Akash, for torpedoes and for missile systems alike. A related and rising form is the one this announcement introduces: a defence contract signed with a company under the Department of Space. Expect a matching item that pairs NSIL with the Department of Space rather than with the Ministry of Defence.
The second is the "first" question. India's first dedicated defence satellite is GSAT-7, and it belongs to the Navy. Candidates routinely reverse it and assign the first to the Air Force, because the Air Force is the service most associated with technology. The sequence worth fixing is: Navy 2013, Air Force 2018, and the Air Force's next satellite now under contract.
The third is the stage question, and it rewards precision. Acceptance of Necessity, Request for Proposal, trials, Contract Negotiation Committee, contract, delivery. A statement that says a system "was purchased" when only an AoN was granted is false, and the paper does write statements that way.
A fourth form worth preparing is the classification question — lightweight against heavy weight torpedo, by diameter and by launch platform. It is a clean two-category distinction, which is exactly what a matching or statement-pair item needs.
In a written answer on self-reliance in defence, the proposition that earns marks is not that both contracts went to Indian entities. It is that they went to Indian entities for different reasons: one buys production of a design the state already owns, the other buys a capability from the commercial arm of the national space programme. Add that the five-year distance between clearance and contract is a feature of the acquisition process and not an aberration, and the answer is doing analysis rather than listing.
Preparing for NDA? Defence procurement questions reward one habit — always separate the designer from the manufacturer, and the clearance from the contract. Build the base with our NDA study material, follow the daily NDA current affairs for contract and trial announcements as they happen, and train with serving-standard faculty in the upcoming Cavalier courses in Delhi.
