The Indian Navy commissioned its fifth Kalvari-class submarine, INS
, on 23 January at Naval Dockyard, Mumbai.
The Indian Navy has commissioned the fifth of its six Kalvari (Scorpène)-class diesel-electric attack submarines (SSKs).
The submarine, INS Vagir (S 25), was inducted in a ceremony on 23 January held at the Naval Dockyard in Mumbai. All the Kalvari (Scorpène)-class SSKs are licence-built by state-owned Mazagon Dockyard Shipbuilders Limited (MDL) in Mumbai in collaboration with France's Naval Group. Vagir joins four other Kalvari-class submarines in the service's Western Naval Command.
Vice Admiral (retd) Narayan Prasad, chairman and managing director of MDL, said at the commissioning that while the new submarine shares a common structure with the four other commissioned boats, Vagir is equipped with more systems built in India. Such items include the boat's main batteries and a Ku-band satellite communications system produced by Electronics Corporation of India Limited, he said.
Prasad also said that MDL has expanded efforts to reduce the submarine's acoustic, optical, electromagnetic, and infrared signatures, but did not elaborate.
MDL had not responded to Janes questions at the time of publication.
Spanish Navy decommissions fourth Galerna-class submarine

The Spanish Navy decommissioned
on 16 February 2024.
The Spanish Navy's fourth S 70 (Galerna)-class conventionally powered diesel-electric submarine (SSK) has been retired from service.
Tramontana (S 74), the youngest of four Galerna-class SSKs, was officially decommissioned during a ceremony held at the Spanish Navy's submarine base in Cartagena on 16 February.
Announcing the milestone the same day, the Spanish Navy said that since entering service in 1985, Tramontana has sailed a total of 315,144 n miles – 218,384 of them submerged. The submarine completed its last (and fourth) major overhaul between 2014 and 2017.
Highlights during Tramontana's career include the launching of a torpedo that sank a surface ship in October 2004. The submarine also contributed to the outcome of the crisis of Perejil Island in 2002, and participated in Operation ‘Unified Protector' in Libya in 2011.
The Galerna-class SSKs were built by Bazán (now Navantia) shipyards in Cartagena, entering service between 1983 and 1985.
Tramontana's decommissioning follows that of Siroco, which was decommissioned in June 2012, and Mistral in June 2020. Its retirement leaves just one remaining submarine, first-of-class Galerna
HII shipyard starts testing aircraft carrier John F Kennedy EMALS with dead-load launches

HII has started testing the catapults on aircraft carrier
John F Kennedy
with dead-load launches.
HII's Newport News Shipbuilding (NNS) unit has started testing of the Electromagnetic Aircraft Launch System (EMALS) on aircraft carrier
John F Kennedy
(CVN 79), marking a major milestone for the ship, HII confirmed on 21 February.
After testing catapults one and two – the bow cats – with no-load launch movements, NNS workers and
sailors started the dead-load testing, HII acknowledged in a release.
For the dead-load testing, large, wheeled car-like structures of graduated weights up to 80,000 lb (36,287.4 kg) to simulate the weight of actual aircraft are launched off the carrier's bow into the James River bordering the shipyard in Virginia, HII said.
The dead loads are retrieved and relaunched until the conclusion of the test programme to ensure the catapults are deemed ready to launch all US Navy (USN) carrier-based fixed-wing aircraft.
Officials connected with the Kennedy programme told
earlier this month that dozens of dead-load shots have been launched.

The Turkish Naval Forces has initiated design activities to advance efforts towards acquiring a domestically built aircraft carrier.
In early January the Turkish government gave the green light during a meeting of the Defence Industry Executive Committee (SSİK), chaired by Turkish President Recep Tayyip Erdoğan, to progress plans for an indigenous aircraft carrier to the design phase.
During a visit to the Design Project Office on 15 February, Turkish government and defence industry officials inspected progress made with the indigenous aircraft project to date. The preliminary design of the future aircraft carrier, which was visible in photos of the visit shared by the
Turkish Navy, shows that the carrier will be in short take-off but arrested recovery configuration.
The design shows a single runway and ski jump of approximately 12–14°, with a single island on the starboard side. Other details such as the number of aircraft elevators and their parking spots were not immediately apparent.
The situation in Yemen is particularly complex. Even before the start of the attacks on shipping in November 2023 by Ansar Allah (commonly known as the Houthis), the country has been of interest to many. A large-scale humanitarian crisis has em...
