Relevance: GS-II Agreements involving India · GS-III Security & Defence Source: RELOS operationalisation, 2026

1 · What happened

India and Russia have switched on a new defence pact called RELOS — the Reciprocal Exchange of Logistics Support agreement. It lets the two militaries use each other’s bases, ports and airfields for fuel, repairs and supplies.

The timeline: signed in Moscow on 18 February 2025, ratified by Russia in December 2025, and brought into force on 12 January 2026 for a five-year term.

It set off some online rumours — that India and Russia had become military allies, or that 3,000 Russian troops would be permanently based in India. Both are false. RELOS is a routine administrative pact, like ones India has with several other countries.

2 · What is a logistics pact?

A Logistics Support Agreement (LSA) simply lets two friendly militaries top up at each other’s bases — fuel, food, spare parts, repairs — without paperwork delays each time. Think of it as a shared pit-stop arrangement. It is not an alliance and does not allow permanent foreign bases.

India began building this network in 2016 with LEMOA (the Logistics Exchange Memorandum of Agreement) with the United States. Since then it has added similar pacts with partners like France, Japan (called ACSA), Australia, Singapore and South Korea — and now Russia.

3 · The key points of RELOS

  • The ceiling: each side may temporarily host up to 3,000 troops, 5 warships and 10 military aircraft. This is an upper limit for big joint exercises — not a standing deployment.
  • A first for India: it is the first time India has allowed a foreign military to station personnel on its soil, even temporarily.
  • When it applies: during joint exercises (like INDRA), training, port calls, and HADR (Humanitarian Assistance and Disaster Relief) — and analysts note it can extend to wartime needs. Payment can even be by barter.

4 · Why it matters for India

New frontier
Arctic access
RELOS opens Russian Arctic and Far-East ports to India. As warming opens the Northern Sea Route, this gives India a foothold in a resource-rich, fast-opening region.
Practical gain
Keeping the fleet running
Much of India’s kit is Russian — Su-30MKI jets, Kilo-class submarines, carrier INS Vikramaditya. RELOS smooths repairs and spare-part supply.
Balancing act
Strategic autonomy
Running RELOS alongside the US pact LEMOA shows India’s multi-alignment — close to the West via the Quad, yet firm with Moscow.
The caution
Sanctions & optics
India must use non-dollar payment channels to shield its banks and units from Western secondary sanctions, and keep the pact clearly non-alliance.
