India Boosts Military Self-Reliance with New Satellite and Anti-Submarine Torpedo Contracts.
India MoD signs contract for dedicated IAF satellite.
India’s Ministry of Defence has signed two contracts worth approximately US$432 million (Rs 4,106 crore) to strengthen the communication capabilities of the Indian Air Force (IAF) and the anti-submarine warfare capabilities of the Indian Navy. The agreements, signed in New Delhi on 15 October 2026, cover the indigenous GSAT-7C communication satellite and Varunastra heavyweight torpedoes.
The contracts represent a significant investment in India’s military modernisation, with both projects involving domestically designed, developed or manufactured defence technologies. The satellite contract, valued at US$270 million (Rs 2,563 crore), has been awarded to New Space India Limited (NSIL), Bengaluru. The second contract, worth US$162 million (Rs 1,543 crore), has been signed with Bharat Dynamics Limited (BDL), Hyderabad, for Varunastra heavyweight torpedoes.
Together, the agreements seek to address two distinct military requirements: secure and reliable communications for the Air Force, and improved capability to detect and engage underwater threats for the Navy. They also support the government’s Aatmanirbhar Bharat and Make in India initiatives, which aim to strengthen domestic manufacturing and reduce dependence on foreign suppliers for critical defence equipment.
What are the two defence contracts about?
Although both agreements fall under military modernisation, they serve different operational purposes.
The GSAT-7C project is intended to strengthen secure communications across the Indian Air Force‘s assets. Modern air operations rely on the rapid and reliable exchange of information between aircraft, command centres and other military units. A dedicated satellite communication capability can help support this flow of information.
Varunastra, meanwhile, is a ship-launched heavyweight torpedo developed for the Indian Navy. It is designed to engage enemy submarines, which can pose a significant threat to naval vessels and other maritime assets.
The two acquisitions therefore address different parts of India’s defence requirements. One focuses on communications and coordination in air operations, while the other strengthens the Navy’s underwater combat capabilities.
GSAT-7C: Strengthening secure communications for the Air Force
The Ministry of Defence has signed the GSAT-7C contract with New Space India Limited for US$270 million (Rs 2,563 crore).
According to the ministry, the satellite has been indigenously designed, developed and manufactured. Its principal purpose is to enhance secure, resilient and seamless communication capabilities for Indian Air Force assets.
Communications are central to modern military operations. Aircraft and command centres need to exchange information quickly to coordinate missions, share instructions and maintain an understanding of developing situations. Interruptions, delays or vulnerabilities in communication networks can complicate operational planning and coordination.
A dedicated military communication satellite can provide an important link in this network by supporting communication over long distances and across geographically dispersed areas.
The emphasis on secure communications is particularly important for defence organisations, where sensitive operational information must be protected from unauthorised access. Resilience is equally important because military communication systems must remain dependable under demanding operational conditions.
The ministry has stated that GSAT-7C will strengthen the operational effectiveness of the Indian Air Force. However, the contract announcement does not provide details about the satellite’s launch date, technical specifications, expected service life or deployment schedule.
These details would be needed to assess the project’s precise capabilities and when the Air Force can expect to benefit from its operational deployment.

Varunastra: Boosting the Navy’s anti-submarine warfare capability
The second agreement covers Varunastra heavyweight torpedoes and has been signed with Bharat Dynamics Limited for US$162 million (Rs 1,543 crore).
Varunastra is an indigenous ship-launched anti-submarine torpedo developed by the Naval Science and Technological Laboratory. The Ministry of Defence describes it as a weapon equipped with advanced manoeuvring capabilities and capable of engaging enemy submarines at long ranges.
Anti-submarine warfare is an important part of naval operations because submarines can operate covertly beneath the surface and threaten military vessels and other maritime assets. Detecting, tracking and responding to such underwater threats requires specialised sensors, trained personnel and suitable weapons.
A heavyweight torpedo is designed to be launched from a naval platform against an underwater target. Its role is different from that of missiles intended to strike targets above the water, as it operates within the underwater combat environment.
Varunastra’s ship-launched capability is intended to strengthen the Indian Navy’s ability to respond to submarine threats. Its manoeuvring capabilities are relevant to the challenge of engaging underwater targets, which may change course or depth during an encounter.
The acquisition is therefore aimed at reinforcing a critical element of India’s maritime defence. The announcement does not specify the number of torpedoes covered by the contract, delivery deadlines or the particular ships scheduled to receive them.
Why indigenous defence manufacturing matters
A key feature of both contracts is their connection to India’s domestic defence manufacturing ambitions.
The government’s Aatmanirbhar Bharat initiative promotes greater self-reliance across strategic sectors, while Make in India seeks to encourage domestic production, investment and industrial development.
Defence equipment presents a particular challenge because military forces require reliable access to advanced technologies, replacement parts, maintenance services and technical expertise. Heavy dependence on foreign suppliers can create vulnerabilities when international supply chains are disrupted or export restrictions affect the availability of equipment.
Developing and manufacturing critical systems domestically can help build national technical expertise and strengthen control over important parts of the supply chain.
The GSAT-7C contract involves New Space India Limited, the public-sector company associated with India’s commercial space activities. The Varunastra contract involves Bharat Dynamics Limited, a defence public-sector enterprise, while the torpedo itself was developed by the Naval Science and Technological Laboratory.
These arrangements connect government agencies, domestic industry and defence research institutions in support of military requirements.
However, domestic production does not automatically eliminate all external dependencies. The overall benefits will depend on the extent of indigenous content, the availability of locally produced components, manufacturing capacity and the ability to maintain the equipment throughout its service life.

Who signed the contracts?
The agreements were signed in New Delhi on 15 October 2026 in the presence of A Anbarasu, Additional Secretary and Director General (Acquisition) in the Department of Defence.
The signing formalises the two procurement agreements and marks another step in India’s efforts to improve its military capabilities through domestic technology and manufacturing.
The ministry has presented the contracts as an important contribution to the country’s defence self-reliance objectives. The announcement, however, does not provide further financial details about payment schedules, delivery milestones or the wider lifecycle costs of either system.

What do the deals mean for India’s military modernisation?
The two contracts demonstrate how military modernisation involves more than purchasing new aircraft, ships or conventional weapons. Secure communications and specialised underwater weapons are also essential to the effectiveness of modern armed forces.
For the Indian Air Force, GSAT-7C is intended to improve the communication infrastructure supporting its assets. For the Indian Navy, Varunastra is expected to reinforce the ability to counter submarine threats.
The agreements also underline the importance of domestic research, manufacturing and industrial capacity in India’s defence strategy. Their long-term value will depend on successful production, timely delivery, integration with existing military systems and dependable performance in service.
At approximately US$432 million (Rs 4,106 crore), the combined investment addresses two different but important operational requirements. It reflects India’s continuing effort to strengthen its armed forces while expanding the role of indigenous technology in national defence.
