How to think it through
Russia's share of India's arms imports fell from about 70% in the 2000s to about 36% in 2020–24 (SIPRI). US platforms (P-8I, C-17, MQ-9B) are maritime and networked, which matters for the Indo-Pacific. Russian platforms (S-400, Su-30, submarines) remain the backbone of land and air power. The answer is complementarity.
Model answer
In the decade to 2010, Russia supplied roughly 70% of India's arms imports. By 2020–24, SIPRI put its share at about 36%, while US, French and Israeli suppliers grew. India's defence map is being redrawn.
What Indo-US deals bring
- Maritime platforms: P-8I aircraft, MH-60R helicopters, 31 MQ-9B drones (2024), suited to watching the Indian Ocean.
- Foundational agreements: LEMOA (2016), COMCASA (2018), BECA (2020), giving logistics access, secure communication and geospatial data.
- Interoperability with the US, Japan and Australia through Malabar.
- Technology and co-production: GE F414 engines for Tejas Mk2, Javelin and Stryker discussions, and a renewed 10-year defence framework (2025).
What Russian deals still give
- The backbone of the forces: Su-30MKI, T-90 tanks, S-400 air defence (proved valuable in May 2025), nuclear submarine leasing, BrahMos joint venture, AK-203 rifles at Amethi.
- Willingness to share sensitive technology that others will not.
- Spares and maintenance needs that tie India for decades.
Significance for Indo-Pacific stability
- US deals strengthen maritime domain awareness and deterrence against Chinese naval expansion, giving smaller states confidence.
- They link India to a network of partners, supporting a rules-based order.
- Russian deals deter on the continental front (the LAC and Pakistan) but add little to the maritime balance, and Russia's growing closeness to China is a concern.
Risks
- CAATSA sanctions threat for Russian purchases.
- Dependence on any single supplier; US supply restrictions in the past.
- Russia's war in Ukraine has delayed deliveries, including the last S-400 units.
Balance
US deals are more significant for the Indo-Pacific; Russian deals remain crucial for the land borders. India's goal is neither, but Atmanirbharta: indigenous production with partners, as defence exports crossing ₹23,000 crore in 2024–25 show.
Conclusion
India buys from both because it faces threats on both land and sea. Strategic autonomy means choosing platforms for the mission, not suppliers for an alliance.
Draw: A map: US platforms over the ocean (blue), Russian platforms along land borders (red).
