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.

UK-based SubSea Craft has joined forces with Capewell Europe to explore the air deployability of its Victa diver delivery unit (DDU) prototype when integrated onboard the latter's newly developed Universal Maritime Craft Aerial Delivery System (UMCADS).

Speaking to Janes on 1 May, Lee Ebsworth, SubSea Craft's chief commercial officer, said the partnership has mutual opportunities as the two companies work together to increase the evidence bank for Victa as a deployable air asset as well as to demonstrate the flexibility of Capewell's UMCADS.

“While we continuously push the technological edge in our platforms to give operators the advantage, their effectiveness hinges on successful deployment into the area of operations,” he said. “We've prioritised ensuring Victa's flexibility in deployment, and conducting feasibility studies with Capewell enables us to expand the available options against the most demanding scenarios.” What is particularly valuable about UMCADS is its configurable nature, which not only supports Victa but also complements other concepts currently in development, he added.
