The Pentagon's Missile Defense Agency (MDA) and its industry counterparts at Lockheed Martin are preparing for the ‘final transition' of the long-awaited Long Range Discrimination Radar (LRDR) to the US armed forces in the Indo-Pacific region.

LRDR programme officials officially transitioned control of the S-band missile defence radar to the MDA on 23 April, according to a company statement. The handover of the system, currently stationed at Clear Space Force Station in Alaska, will allow agency officials to finalise the Operational Capability Baseline (OCB) milestone, which is the final stage before the LRDR is handed over to US Space Force (USSF) units. “Prior to this transition, the system has started space domain awareness data collects” for USSF units, the 23 April statement said.

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 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.
