The Ohio-class ballistic missile submarine USS Louisiana (SSBN 743) launched an unarmed life-extended Trident II (D5LE) missile on 27 September on the Western Test Range off the coast of San Diego, California for a scheduled missile test flight, the US Navy (USN) confirmed on 28 September.

This test marked the 191st successful Trident II (D5 & D5LE) strategic weapon system (SWS) missile launch since starting operations in 1989, USN officials said.

The tests help sustain the weapons system and ensure the United States sea-based strategic deterrence capability through 2084, Vice Admiral Johnny Wolfe Jr, the director for Strategic Systems Programs, said in a statement.

The navy purchased over 530 D5 missiles to support the Trident fleet, the Congressional Research Service (CRS) noted in a report released in May on US strategic forces.

Ten personnel are dead after two Royal Malaysian Navy (RMN) helicopters collided during a rehearsal for the service's 90th anniversary parade, the service disclosed in a media statement on 23 April.

All personnel are from the two helicopters involved, namely a Leonardo AW139 medium-lift rotorcraft and an AS 555SN Fennec airframe, the statement added.

The service has since confirmed to Janes that the AW139 bears the serial number M503-3 while the Fennec was registered with the serial number M502-5.

The aircraft collided at 0932 h local time while they were flying over the RMN's Lumut naval base.

A video of the mid-air collision that began circulating on instant messaging apps shortly after the accident indicates that the Fennec's main rotor clipped the AW139 on the latter's port side while both aircraft were making a right turn during a fly-past segment of the rehearsal.

The Next Generation Interceptor (NGI) competition has come to an end as Lockheed Martin was selected as the prime to continue development of the weapon through critical design review (CDR), all-up round qualification, integration with the Ground-Based Midcourse Defense (GMD) system, and flight testing, the US Missile Defense Agency (MDA) announced on 15 April.

While no dollar amount was attached to initial statements on the contract, the Pentagon's Cost Assessment and Program Evaluation (CAPE) said in a 2021 report that it expected NGI to accrue roughly USD17.7 billion in contract costs. The downselect for Lockheed Martin will lead to a follow-on production and emplacement contract to support initial operational capability for NGI by the fourth quarter of fiscal year (FY) 2028, according to the announcement.

The MDA cited “technical maturity”, “technical rigor” in the design process, and contract-provided performance date as key factors that supported its decision.

Lieutenant General Heath Collins, director of the MDA, called the decision “very difficult” in a statement but said the agency was “confident”.

The Ultra Light Tactical Vehicle (ULTV) programme – a US Marine Corps (USMC) replacement for the ageing Utility Task Vehicle (UTV) – will now include a variant with more exportable power, according to Janes analysis of budget documents.

The fiscal year (FY) 2025 budget request is the first time the ULTV-High Power (ULTV-HP) has funding for procurement, adding up to roughly USD5.99 million for 40 vehicles in that year. USMC justification documents indicate that it “provides exportable electrical power generation in support of the requirements for [the] kill web integrating system”.
