US Naval Air Systems Command (NAVAIR) accepted delivery of the first two Textron T-54 Multi-Engine Training System (METS) aircraft at Naval Air Station (NAS) Corpus Christi, Texas, the service announced on 22 April. The aircraft are set to begin training students at NAS Corpus Christi's Training Air Wing Four in boreal spring 2025, the US Navy (USN) told Janes .

The USN intends to operate 64 of the Textron King Air 200-based aircraft, which will replace the Textron T-44 as the service's main twin-engine pilot training aircraft. Deliveries are set to run through 2026, and the aircraft is meant to operate until 2055.

“This aircraft brings modernised training to student naval aviators and prepares them for the advanced aircraft they will fly in the fleet,” said Captain Duane Whitmer, USN programme manager.

Hypersonix Launch Systems, headquartered in Brisbane, is building a hypersonic test vehicle for the Defense Innovation Unit's (DIU's) hypersonic and high-cadence testing capabilities (HyCAT) programme. DIU issued a solicitation for the project in September 2022. Hypersonix Launch Systems was awarded a contract for scoping the work in March 2023, and a launch contract in September 2023, Matt Hill, Hypersonix Launch Systems CEO, told Janes on 9 April at the Navy League Sea-Air-Space 2024 global maritime exposition in National Harbor, Maryland.

The programme calls for an airborne test vehicle “that can maintain speeds above Mach 5 with a manoeuvrable/non-ballistic flight profile and at least a three-minute flight duration with near-constant flight conditions”, according to a DIU statement in April 2023.

Construction of the first DART air vehicle is under way, and Hypersonix Launch Systems recently completed the component-level preliminary design review, Hill said. Rocket Lab will provide the launch capabilities for the system for the initial test flight.

The US Navy (USN) has commenced operations of its Northrop Grumman MQ-4C Triton Broad Area Maritime System (BAMS) in the European theatre, with the first unmanned aerial vehicle (UAV) departing Naval Air Station (NAS) Sigonella in Sicily for its first sortie on 17 April.

The milestone was logged by online flight tracking services about two weeks after the USN announced in late March that the first of an undisclosed number of UAVs had arrived in its Sixth Fleet area of operations.

Derived from the Block 30 RQ-4N naval variant of the RQ-4 Global Hawk high-altitude long-endurance (HALE) UAV, the Triton has been developed to provide the USN with a persistent maritime intelligence, surveillance, and reconnaissance (ISR) capability in support of a full range of military operations that includes signals intelligence, communications relay, and search and rescue.
