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 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 Italian National Armaments Directorate (NAD) is procuring three ground-based sensors to enhance the country's space situational awareness (SSA), Janes learnt at the Military Space Situational Awareness Conference 2024, held in London from 22 to 24 April.

In total, two optical telescopes and one high-performance radar are being procured as part of its national SSA plans, Lieutenant Colonel Ferdinando Dolce, the head of SSA at NAD, said at the conference.

The first sensor being procured is a high-performance optical surveillance telescope from OHB Italia called Flyeye, Lt Col Dolce said.

Flyeye will have the capacity to monitor objects in low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO), Commander of the Space Situational Awareness Centre at the Italian Air Force Colonel Dario Tarantino told Janes
