Hanwha Ocean has unveiled its latest, stepped-up proposal submitted for the Philippine Navy's (PN's) two-boat submarine requirement.

A computer-generated image (CGI) of the proposal, which has been dubbed as the Jangbogo-III PN submarine, was provided to Janes on 19 September ahead of a media release on the same day.

The vessel is derived from the Republic of Korea Navy's (RoKN's) KSS-III submarine, which has been designed and constructed by Hanwha Ocean. The proposed vessel has a surface displacement of about 2,800 tonnes, with an overall length of 77 m, and an overall beam of 9.7 m.

“Building upon the success of the Korean navy's (RoKN's) Jangbogo-III submarines, Hanwha Ocean's proposal, the Jangbogo-III PN (Philippine Navy), offers a proven platform that delivers unparalleled operational capability,” according to a company statement.

“This advanced submarine is equipped with the latest propulsion system and lithium-ion battery technology ensuring the Philippines' enhanced defence capability to safeguard its sovereign and strategic maritime interests,” the statement added.

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'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 Kennedy 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 Janes 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.
