  2. Limitations
  3. Evolving role of NSIL

A force multiplier is a capability that makes existing forces far more effective. On 15 October 2026 the MoD signed a ₹2,563-crore contract with NSIL for GSAT-7C. It is an indigenous satellite meant to give the IAF secure communications [1]. The deal shows that dedicated satellites have moved from supporting assets to core combat assets.

GSAT-7 series as force multiplier

  • Network-centric operations: GSAT-7 'Rukmini' (2013) was India's first dedicated naval satellite [2]. GSAT-7R (CMS-03) now links the Navy's ships, submarines, aircraft and Maritime Operations Centres across the Indian Ocean Region [4].
  • Air power: GSAT-7A (2018) [3] and now GSAT-7C give beyond-line-of-sight, resilient links to IAF assets, with less dependence on ground networks [1].
  • Maritime domain awareness: GSAT-7R's multi-band voice, data and video links support continuous surveillance of the IOR [4].
  • Strategic autonomy: Indigenously built satellites avoid leased foreign transponders that could be denied during a crisis [1][4].

Limitations

  • Replacement cycle: Rukmini's successor came about 12 years later [2][4]. The IAF will face the same timeline, so any delay leaves gaps in coverage.
  • Vulnerability: Anti-satellite weapons and jamming put single, high-value satellites at risk. This calls for redundancy, hardening and space situational awareness.
  • Cost and scale: A handful of satellites cannot serve all three services. Joint planning, for example through the Defence Space Agency, is still developing.

Evolving role of NSIL

  • The 2020 space reforms moved NSIL from a supply-driven to a demand-driven model. NSIL now gathers what users need and owns operational satellites [5].
  • The services can now order satellites built to their own specifications, as the IAF did with GSAT-7C, while ISRO focuses on research and development [1][5].
  • Opening the sector to private firms (IN-SPACe) can widen the supplier base and shorten delivery times [5].

In short, the GSAT-7 series shows that secure satellite links multiply the reach of India's air and naval power, and NSIL's demand-driven model makes such satellites easier to buy. The way forward is planned replacement cycles, constellations with redundancy, and integration across the three services under the Defence Space Agency. That would turn Aatmanirbharta in space into lasting deterrence.
