1. US Navy’s tweet on deployment of French submarine in West Pacific

US Navy, the official account of US Navy, shared an article about the deployment of the French nuclear-powered submarine (SSN), FS Emeraude, in Western Pacific. The deployment gave a unique training opportunity for the US Navy’s USS Asheville, a Los Angeles-class fast-attack submarine. Emeraude and the Loire-class support and assistance vessel (BSAM type) FS Seine are on a planned deployment to the Western Pacific.

Asheville and Emeraude utilised the deployment to learn high-end maritime skills over a period of few days in various disciplines. These exercises are devised to improve co-ordination and battle skills among maritime forces.

Currently, three Submersible Ship Nuclear (SSN) general-purpose attack submarines and four Submersible Ship Ballistic Missile Nuclear (SSBNs) ballistic missile-carrying submarines, belonging to the UK’s Royal Navy are either in the construction or planning phases.

A pressure hull section of one of the submarines, the HMS Dreadnought, moved into central coatings facility in December. This is one of the world’s biggest submarine constructions being undertaken in Barrow.

5. Tyler Rogoway’s tweet on Israeli drones meeting US Navy requirements 

Tyler Rogoway, editor of The War Zone, a website providing information on defence, shared an article about how an Israeli firm’s products could meet the US Navy’s requirements for unmanned aircraft for its submarine launchers.

An Israeli firm, Spear, released its Ninox line of encapsulated drones during the same time as the US Navy’s announcement. The drones can be released from 40mm infantry grenade launchers and 66mm grenade launchers mounted on vehicles and underwater launch systems. 

The Naval Sea Systems Command (NAVSEA), however, stated that it was currently looking for potential Submarine-Launched Unmanned Aerial System (SLUAD) designs with a 3in diameter form-factor to enhance communication, sensor and cyber-security capabilities, rather than drone acquisitions.

6. Military Times’ tweet on US Navy’s frigate programme

Military Times, a website covering military news and information, shared an article on the Congress pushing the US Navy to get its frigate programme, also known as the FFG(X), right after citing engineering failures in its littoral combat ships (LCS).

According to a 2021 National Defence Authorisation Act, the US Navy will now be required to establish a land-testing site for the engineering plant for its new Constellation-class FFG(X) programme.

The frigate programme will introduce a new propulsion system, which has not been used in the navy before. Adapted from Fincantieri’s FREMM design, the aim was to use an existing design to reduce technical, design, and integration flaws.

9. 9DASHLINE’s tweet on discovery of Chinese submarine drone in the Indian Ocean

9DASHLINE, a website providing analysis on the Indo-Pacific region, shared an article on a Chinese submarine drone being discovered near the Selayar Island in South Sulawesi province in Indonesia. The drone was found by Indonesian fishermen and may have been assessing Indonesian waters to evaluate potential ways to penetrate into the Indian Ocean.

The glider drone was found near two strategic routes between the Indian Ocean and South China Sea, the Lombok Strait and the Sunda Strait. This raises concerns over the possibility of the Chinese Navy collecting significant information via the drones to utilise the two straits during future hostilities.
