The UK Royal Navy's (RN's) Daring (Type 45)-class destroyer HMS Diamond (D 34) has successfully engaged an anti-ship ballistic missile (ASBM) launched by Yemen-based Ansar Allah (commonly known as Houthi) rebels targeting a merchant ship in the Gulf of Aden, the service confirmed on 25 April.

During the incident, which took place around 1151 h local time (Sanaa time) on 24 April, Diamond used its Sea Viper anti-air guided weapon system to shoot down the missile, the navy said. According to a US Central Command (CENTCOM) statement issued on 25 April, the missile was likely targeting the US-flagged, owned, and operated merchant vessel MV Yorktown, which has 18 US and four Greek crew members onboard.

No injuries or damage was sustained by the ship or its crew, CENTCOM said.

The UK's Defence Science and Technology Laboratory (Dstl) is conducting three technology demonstrator programmes to explore the utility of novel space domain awareness (SDA) technologies.

The first programme is exploring the development of a Deep Space Radar (DSR) designed to monitor and protect geostationary orbit (GEO) assets such as the Skynet satellite communications system, William Feline, senior principal advisor for SDA at the UK Ministry of Defence (MoD), said at the Military Space Situational Awareness Conference 2024, held in London from 22 to 24 April.

The purpose of the programme is also to assess whether the UK needs its own DSR capability or whether it can rely on or complement the Deep Space Advanced Radar Capability (DARC) currently being developed alongside Australia and the US, Emma Kerr, senior principal engineer for SDA at Dstl told Janes .

A monostatic or biostatic system is being considered as well as whether a new or existing system is required, Feline said.

The last US Coast Guard (USCG) Airbus MH-65 Dolphin in Alaska retired from Air Station Kodiak on 23 April, ending the type's 36-year employment in the service's Alaska Patrol (ALPAT) role.

“For decades, the cutter and helicopter team were the core of the ALPAT mission,” said Commander James Kenshalo, a USCG MH-65 Dolphin pilot. “Together they projected force and protection to the most extreme remote regions of our nation's territories, operating beyond where help could reach.”

Air Station Kodiak operates six Sikorsky MH-60Ts and is scheduled to receive three more in 2025. The service intends to standardise its full rescue helicopter fleet on the MH-60T, which has a longer range, greater payload capacity, and commonality with other armed service fleets. Alaska is among the first regions to complete the transition because of the long ranges required to perform rescue and security missions in the region.
