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.

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.”
