HII's Newport News Shipbuilding (NNS) unit confirmed on 25 April it had delivered Virginia-class fast-attack submarine New Jersey (SSN 796) to the US Navy (USN) in a release, noting the SSN is scheduled to be commissioned later in 2024.

The submarine delivery comes at a time when the USN shipbuilding is coming under scrutiny – with the Virginia-class programmes being one of the efforts coming under intense focus – for running far behind schedule.

Not only is the Virginia shipbuilding programme off schedule, but lawmakers are questioning the recent USN fiscal year (FY) 2025 budget request for only a single submarine, when two were expected.

However, USN officials noted they are making the best decisions possible because of workforce and supply-chain issues that continue to plague the efforts to build submarines and other naval vessels.

New Jersey is the 11th Virginia-class submarine delivered by NNS and the 23rd built as part of the teaming agreement with General Dynamics Electric Boat.

China's Poly Defence displayed models of a series of new combat and reconnaissance unmanned surface vessels (USVs) and diver support vessels at the Defence Services Asia (DSA) 2024 exhibition in Kuala Lumpur.

The displayed vessels included the Scout S45 surveillance USV, the Cavalry A150 attack USV, the A2000 attack and surveillance USV, the SDV-1 surface/underwater diver delivery vehicle, and the UPV-3D underwater diver propulsion vehicle.

The company provided few details about the products, apart from clarifying that all vessels were under development. The company also confirmed that a separate project is under way to deploy the systems in a networked environment for co-ordinated reconnaissance and combat operations in littoral waters.

A Poly Defence official also said the Scout S45 surveillance USV and Cavalry A150 attack USV can be networked with each other to carry out coastal interdiction operations. The A2000 USV is integrated, although its specific role was not stated.

Danish Defence Command has published a report on the technical issues experienced by Royal Danish Navy (RDN) frigate HDMS Iver Huitfeldt (F 361) during an engagement on 9 March 2024 in the Red Sea as part of the US-led multinational task force Operation ‘Prosperity Guardian'.

The 13-page report released on 2 May found that a previously unknown issue with the frigate's Raytheon Mk 56 vertical launching system (VLS) was experienced during the engagement, resulting in an inability to use Raytheon RIM-162B Evolved SeaSparrow Missiles (ESSMs) for approximately 30 minutes. The engagement, which lasted just under one hour, saw the frigate destroy four unmanned aerial vehicles (UAVs) controlled by the Yemeni rebel group Ansar Allah (popularly known as the Houthis) using previously fired ESSM and 76 mm gunfire.

Chinese defence company Poly Technologies showcased the A2000, a new next-generation combat unmanned surface vessel (USV), at the Defence Services Asia (DSA) 2024 exhibition held in Kuala Lumpur from 6 to 9 May.

The A2000 attack USV has a length of 45 m, a displacement of 280 tonnes, and a top speed of 35 kt. It features twin diesel engines and two controllable pitch propellers.

It is equipped with an active electronically scanned array (AESA) radar for surveillance and is integrated with an eight-cell vertical launching system for launching surface-to-air missiles, and 24-cell launchers at both sides for rockets. However, it is not fitted with anti-ship missile launchers.

The USV can co-ordinate with smaller vessels for a swarm attack, provide air defence, and extend its reach via satellite connectivity. Its trimaran hull design minimises radar detection. It also supports vertical take-off and landing (VTOL) unmanned aircraft system (UAS) operations for enhanced surveillance, positioning it as a versatile asset for peacetime and conflict scenarios.
