Exercise Varuna is the premier bilateral maritime warfare exercise conducted annually between the Indian Navy and the French Navy (Marine Nationale). Inaugurated in 1993 as a cooperative naval interaction, the engagement was formally christened 'Varuna' in 2001, named after the ancient Vedic deity symbolizing the oceans, cosmic water, and divine cosmic order. The exercise has evolved from basic tactical passage maneuvers into a high-intensity, multi-domain warfighting drill spanning advanced air defence, complex anti-submarine warfare (ASW), surface combat firings, and carrier strike group interoperability. Conducted alternately in the Arabian Sea, the Bay of Bengal, and the South-Western Indian Ocean, Exercise Varuna 2026 underscores the mature defence pillar established under the India–France Strategic Partnership forged in 1998 and reaffirmed through the bilateral 'Horizon 2047' roadmap.

The operational scope of modern Varuna drills encompasses joint Carrier Strike Group (CSG) maneuvers, frequently bringing together India's indigenous aircraft carrier INS Vikrant or INS Vikramaditya alongside France's flagship nuclear-powered aircraft carrier FS Charles de Gaulle. Aerial operations feature coordinated combat sorties involving carrier-borne Dassault Rafale-M fighters, MiG-29K naval jets, maritime patrol aircraft such as the Indian Navy's Boeing P-8I Neptune and French Atlantique 2, as well as shipborne multi-role helicopters including the MH-60R Seahawk, NH90 Caïman, and Sea King. Undersea warfare training pairs Kalvari-class diesel-electric attack submarines (indigenously constructed under Project-75 based on French Naval Group Scorpène designs) against French nuclear attack submarines (SSNs) of the Rubis or Suffren class, validating advanced passive sonar tracking, acoustic screening, and simulated anti-ship missile engagements.

Tactical execution in the Indian Ocean Region is facilitated by the landmark India–France Reciprocal Logistics Support Agreement (RLSA) signed in March 2018. This treaty allows reciprocal access to sovereign military bases, enabling Indian warships and maritime patrol aircraft to refuel, replenish, and repair at French military installations on Réunion Island in the South-Western Indian Ocean and Djibouti in the Horn of Africa. Cross-deck landings, joint search and rescue exercises, visit board search and seizure (VBSS) operations, and shared tactical communications strengthen interoperability in maintaining secure sea lanes of communication across the Indo-Pacific. Within the wider framework of bilateral defence cooperation, Varuna pairs with Exercise Garuda (Indian Air Force and French Air and Space Force), Exercise Shakti (bilateral armies), and Exercise FRINJEX.

Exercise Varuna is the bilateral maritime exercise conducted annually between the Indian Navy and the French Navy (Marine Nationale).

Initiated in 1993, the bilateral naval drills were officially named 'Varuna' in 2001 after the Vedic ocean deity.

The exercise takes place alternately in the Arabian Sea, the Bay of Bengal, or the South-Western Indian Ocean.

Exercise Varuna constitutes the maritime component of the India–France Strategic Partnership established in January 1998.

In July 2023, during Prime Minister Modi's visit to Paris as Bastille Day Guest of Honour, both nations adopted the 'Horizon 2047' roadmap.

The exercise features advanced Carrier Battle Group operations, integrating INS Vikramaditya or INS Vikrant with the French nuclear-powered aircraft carrier FS Charles de Gaulle.

Fighter aircraft deployed during maneuvers include Indian MiG-29K jets and French Navy carrier-capable Dassault Rafale-M fighters.

Anti-submarine warfare (ASW) modules utilize Indian Boeing P-8I Neptune long-range maritime patrol aircraft and French Atlantique 2 aircraft.

Undersea warfare training engages Indian Kalvari-class (Scorpène-design) diesel-electric submarines against French Rubis-class or Suffren-class nuclear attack submarines.

#10

Six Kalvari-class submarines were built indigenously at Mazagon Dock Shipbuilders Limited (MDL) in Mumbai under Project-75 with French transfer of technology.

#11

In 2018, India and France signed a landmark Agreement on Reciprocal Logistics Support (RLSA), permitting reciprocal naval access to military bases.

#12

Under the RLSA, the Indian Navy accesses French naval facilities at Port des Galets on Réunion Island and the French military base in Djibouti.

#13

Tactical modules include air defence exercises, surface live-weapon firings, electronic warfare drills, and Visit Board Search and Seizure (VBSS) operations.

#14

Complex underway replenishment (UNREP) at sea validates interoperable fueling and cargo transfer protocols between Indian and French logistics fleet tankers.

#15

In 2021, the 19th edition of Varuna incorporated the United Arab Emirates (UAE), conducting the first trilateral naval exercise in the Arabian Sea.

#16

Exercise Garuda is the corresponding bilateral aerial combat exercise between the Indian Air Force and the French Air and Space Force.

#17

Exercise Shakti is the corresponding biennial land combat exercise between the Indian Army and the French Army.

#18

Exercise FRINJEX is a joint humanitarian assistance and counter-terrorism military exercise between the Indian Army and French Army launched in Kerala in 2023.

#19

Exercise Varuna reinforces shared commitments to a free, open, and rules-based Indo-Pacific maritime order in compliance with UNCLOS 1982.

Educator's Insight

Exercise Varuna demonstrates high-end naval interoperability between two resident Indian Ocean powers. Unlike basic ceremonial drills, Varuna tests complex multi-carrier maneuvers, carrier strike group coordination, and combined anti-submarine hunts. With both nations operating Western-compatible tactical datalinks and shared hardware platforms like Scorpène-class submarines, Varuna transforms diplomatic partnership into concrete blue-water operational capability.

Candidates frequently mix up bilateral exercise names between India and France across different military branches. Keep them distinct: Varuna is Navy, Garuda is Air Force, Shakti is Army, and FRINJEX is joint Army disaster/combat response. Do not confuse Exercise Shakti with Mitra Shakti (India–Sri Lanka) or Harimau Shakti (India–Malaysia). A useful mnemonic for French bilateral drills is V-G-S: Varuna on water, Garuda in the skies, and Shakti on land.
