Rafale Marine Trials: Preparing for Carrier Operations on INS Vikrant

Why a carrier needs more than a suitable aircraft

An aircraft carrier is a seagoing airbase, but its flight deck is not an ordinary runway. Aircraft must take off, return and move around within a limited area while the ship also performs its wider tasks. A fighter's performance is therefore only one part of the requirement. Its launch method, recovery equipment and physical fit must work with the carrier. Training and maintenance then have to support repeated operations, rather than a single demonstration.

The Rafale is a multirole combat aircraft built by France's Dassault Aviation. The manufacturer lists air-superiority, strike and reconnaissance among its roles. Air superiority concerns control of airspace, while reconnaissance gathers information. A carrier-based fighter can therefore contribute to more than one kind of task. However, a general list of an aircraft family's capabilities does not specify the weapons or mission configuration available to every operator at every stage.

INS Vikrant was commissioned at Kochi on 2 September 2022. It was designed by the Indian Navy's Warship Design Bureau and built by Cochin Shipyard Limited. Commissioning brought the ship into naval service; it did not mean that every future aircraft type was already integrated. Indeed, the Ministry of Defence's pre-commissioning account separately identified later fixed-wing deck-integration trials. The ship's construction milestone and the introduction of a new air wing answer different capability questions.

How launch and recovery work

Vikrant uses Short Take-Off But Arrested Recovery, commonly shortened to STOBAR. Its ski-jump ramp helps launch an aircraft from the flight deck. On return, arresting wires are used to bring the aircraft to a stop over a much shorter distance than a normal runway permits. The two functions must not be confused: the ramp concerns take-off, while the arresting system concerns recovery. Neither is simply a description of the aircraft's maximum speed.

The Rafale Marine was developed for operations from France's Charles de Gaulle, which uses catapult-assisted launches. India's carriers use ski-jumps instead. A catapult adds launching force through external equipment; a ski-jump redirects the aircraft's take-off path. This difference makes compatibility trials necessary even for an aircraft already used at sea. The requirement is to validate the aircraft-and-carrier combination intended for Indian operations, rather than simply rely on its service elsewhere.

The role of the Goa test facility

The shore-based test facility is at INS Hansa in Goa, on India's western coast. Goa faces the Arabian Sea and shares land boundaries with Maharashtra and Karnataka. The facility reproduces important carrier launch and recovery arrangements ashore. It allows the Navy to examine aircraft operation without conducting every test during a sea deployment. The geographical distinction matters: a trial at a naval air station is not a landing on the ship itself.

The facility has supported earlier development work. In September 2019, the Ministry of Defence recorded a naval Light Combat Aircraft prototype completing ski-jump launch and arrested recovery in one sortie. That programme involved exploring hardware arrangements, flight-control options and structural requirements. The example shows why repeated testing can refine an operating system over time. It does not establish the Rafale's results, because a demonstration involving one aircraft cannot certify another aircraft type.

Deck space is a separate engineering question

The October report links possible carrier changes to the Rafale's non-folding wings and the space needed for handling and stowage. Aircraft must be accommodated on the flight deck and moved between it and the hangar below. That is a different question from whether the fighter can become airborne. A carrier air wing must be manageable as a working group of aircraft, not just fit one stationary aircraft within an outline.

Dassault's published specifications give the Rafale a wingspan of 10.90 metres. That measurement helps explain why physical clearance matters, but it does not by itself settle compatibility with a particular ship. The relevant arrangement includes handling space and the equipment through which aircraft are moved. The report says changes were being considered, without supplying a completed engineering design. It does not establish that all modifications had already been carried out.

What India actually contracted to acquire

The governments of India and France signed the procurement agreement on 28 April 2025. The Ministry of Defence specifies 22 single-seat aircraft and four twin-seat aircraft, together with training, simulators, weapons and support. The numbers describe a package with different components, not 26 identical single-seat fighters. Dassault separately distinguishes its naval single-seat Rafale M from the land-based single-seat Rafale C and twin-seat Rafale B. Similar names and shared equipment should not obscure those variant differences.

The ministry's original announcement said deliveries would be completed by 2030, with crews training in France and India. That was the announced programme schedule, not a statement that all aircraft had already arrived. Trials, delivery, crew preparation and operational availability are separate milestones. They can overlap in a procurement programme, but one should not be used as a substitute for evidence that another has been completed.

Support arrangements determine whether capability can be sustained

The agreement also provides for integrating indigenous weapons through technology transfer and establishing specified production and support facilities in India. These include fuselage production and maintenance, repair and overhaul facilities for engines, sensors and weapons. Such provisions describe what the agreement includes, not proof that every facility is already functioning. Their practical value depends on implementation, trained personnel and the ability to support aircraft throughout service.

Commonality with the Indian Air Force's Rafale fleet offers a basis for cooperation in training and support, as the defence ministry notes. But shared equipment does not remove the Navy's carrier-specific requirements. Deck operations, shore preparation and the organisation of a carrier air wing remain additional responsibilities. It is therefore more useful to examine how those systems fit together than to judge the programme only by the number of aircraft ordered.

Why the distinction matters for naval capability

Dassault's April 2025 announcement links the naval contract to the Rafale Marine's selection in July 2023 and experience with the French Navy. For India, the procurement is part of building the carrier's aviation capability, rather than replacing the carrier itself. The useful outcome is an aircraft-and-ship combination that can be operated and supported reliably. A purchase establishes the acquisition framework; integration turns that framework into a usable system.

Conclusion

The Goa trials highlight the work between choosing a fighter and operating it routinely from an aircraft carrier. Launch and recovery, deck handling, trained crews and support arrangements are connected requirements, not interchangeable achievements. Vikrant's earlier commissioning and the Rafale contract provide the platform and acquisition background. The integration programme must bring them together. Reporting its progress accurately therefore requires clear distinctions between trials, contemplated changes, deliveries and demonstrated operational capability.
