The UK Royal Air Force (RAF) and the Royal Australian Air Force (RAAF) stood up their respective 80 Squadrons on 17 April to serve as US-based data units for the Lockheed Martin F-35 Lightning II Joint Strike Fighter (JSF).

Announced by the RAF, the two separate but linked squadrons were reconstituted during a joint ceremony at Eglin Air Force Base (AFB) in Florida.

“At the event, the [UK] Chief of the Air Staff, [Air Chief Marshal] Sir Richard Knighton, and [Australian] Chief of the Air Force Air Marshal Robert Chipman, formally awarded the dormant 80 Squadron number plates for each service to their respective teams within the Australia, Canada, and United Kingdom Reprogramming Laboratory [ACURL],” the RAF said.

Members of the House Armed Services Seapower and Projection Forces Subcommittee raised concerns about the proposed US Navy (USN) plan to pare down key shipbuilding programmes on 17 April during the subcommittee hearing on the USN's Fiscal Year (FY) 2025 budget request.

While the USN – as was the case with the rest of the Pentagon – was charged with keeping a lid on costs, lawmakers said they felt the USN went too far with some major programmes.

Connecticut Congressman and ranking member of the Seapower and Projection Forces Subcommittee, Joe Courtney, set the tone with his opening statement.

“The Fiscal Responsibility Act (FRA), which [was] passed in May 2023 to avert a default on the full faith and credit of our nation's currency and bonds, mandated a 1% increase in the Department of Defense's budget request for fiscal year 2025,” Courtney said.

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.
