Dedicated military satellites are force multipliers in network-centric warfare. Examine India's progress in building service-specific space assets.

Network-centric warfare links sensors, weapons and commanders into one live battle picture. Dedicated military satellites carry that picture over secure, beyond-line-of-sight links that the forces themselves control. On 15 October 2026 the Ministry of Defence signed the contract for the IAF's GSAT-7C [1]. That contract shows India making steady but uneven progress towards space assets for each service.

Why dedicated satellites multiply force

• Own, secure bandwidth: the forces depend less on shared or commercial transponders. GSAT-7C is meant to give IAF assets "secure, resilient & seamless" communication [1].
• Reach: they link ships, aircraft and shore stations across the Indian Ocean Region [2].
• Faster decisions: a shared real-time picture shortens the time between spotting a target and striking it, which raises operational effectiveness [1].

India's progress

• Navy: GSAT-7R (CMS-03), about 4,400 kg, was launched on LVM3-M5 in November 2025. It is India's heaviest communication satellite and covers the Indian Ocean Region [2].
• Air Force: GSAT-7A was launched on GSLV-F11 in 2018 [3]. GSAT-7C, contracted with NSIL for Rs 2,563 crore, adds a second dedicated satellite [1].
• Indigenisation: GSAT-7C is indigenously designed, developed and manufactured. It is bought commercially from NSIL, in line with Aatmanirbhar Bharat [1].
• Institutions: the tri-service Defence Space Agency exists to make space assets serve joint operations.

Gaps that remain

• Stovepipes: a separate satellite for each service risks networks that do not easily talk to each other. Joint operations, not single-service links, are where the real gain lies.
• Resilience: a satellite in a fixed orbit is one asset in a known place, open to counter-space threats. Real redundancy needs GSAT-7A and 7C working together, plus ground links and cross-links with the Navy's GSAT-7R [1][2][3].
• Slow procurement: one acquisition takes 74–106 weeks, which the Standing Committee on Defence called too long given the security risks India faces [4].

India has moved from shared bandwidth to indigenously built satellites owned by the Navy and the IAF. The next step is to join them into one redundant tri-service network under the Defence Space Agency, with faster buying under a revised acquisition procedure. That would make space a real force multiplier and advance self-reliance in critical technologies [1].
