The US Air Force (USAF) is moving headlong into the prototype phase of the service's new, open architecture-based signals intelligence (SIGINT) programme, tapping Northrop Grumman and BAE Systems to develop the sensor hardware and networking backbone in support of the effort.

Engineers at BAE Systems and Northrop Grumman will provide prototype SIGINT sensor platforms for the USAF's Global High-altitude Open-system Sensor Technology (GHOST) programme, according to statements by both defence companies. Based on a scalable, open systems architecture and an expeditionary chassis, the eventual SIGINT sensor platform fielded under the GHOST programme will enable service officials to employ the sensor on a variety of manned and unmanned aerial systems within the USAF's intelligence, surveillance, and reconnaissance (ISR) arsenal.

US contractor Kratos Defense & Security Solutions is to provide the rocket booster motor for the DART AE multimission hypersonic drone technology demonstrator being developed by Australian company Hypersonix Launch Systems.

Announcing the agreement on 25 January, the two companies said they were aiming for a first flight of DART AE in 2023.

DART AE is being developed by Hypersonix as a multimission, hypersonic vehicle fully 3D-printed from high-temperature alloys and powered by a hydrogen-fuelled SPARTAN scramjet engine. Designed to operate at speeds between Mach 5 and Mach 12, SPARTAN is described by Hypersonix as a “fifth-generation, zero-emission, clean hydrogen scramjet engine with a publicly disclosable range of 500 km”.

Amiga Engineering has previously been contracted by Hypersonix for the additive engineering build of the SPARTAN scramjet. Manufacture is being undertaken under an Australian government grant, awarded in August 2020, covering the build of a flight-ready scramjet engine and fuel system.

A CH-53K King Stallion (foreground) and a CH-53E Super Stallion (background) are staged during a redesignation ceremony at Marine Corps Air Station New River, North Carolina, on 24 January. The squadron received its first CH-53K King Stallion, and the ceremony signified the beginning of the US Marine Corps' modernisation from the legacy CH-53E to the CH-53K in support of the expeditionary warfare vision for future-force employment.

The US Marine Corps (USMC) has stood up its first operational unit for the Sikorsky CH-53K King Stallion heavy-lift helicopter, the service announced on 15 January.

Marine Heavy Helicopter Squadron (HMH) 461 at Marine Corps Air Station (MCAS) New River, North Carolina, has been formally redesignated as the first fleet CH-53K unit, trading in its CH-53E Super Stallions.

“The CH-53K will allow the quick massing of combat power, agile manoeuvre, resilient logistics, and predictive maintenance, and be used in the Marine Corps' execution of expeditionary advanced base operations, a key component of the commandant of the [US] Marine Corps' force design,” the USMC said.

NATO has bolstered its enhanced air policing (eAP) mission, with nations providing additional aircraft as concerns over Russian military action in Ukraine grow.

The alliance announced on 26 January that US Air Force (USAF) Boeing F-15E Strike Eagles and Royal Danish Air Force (RDAF) Lockheed Martin F-16 Fighting Falcons were being dispatched to Estonia and Lithuania respectively to supplement the current Baltic Air Policing mission.

“[USAF] F-15s have landed at Amari Air Base, Estonia, [on 26 Janaury] and [RDAF] F-16s will arrive at Siauliai Air Base, Lithuania, [on 27 January] to bolster the forces already deployed under the long-established NATO Air Policing mission,” NATO Allied Air Command said. “Danish F-16s will arrive in Siauliai to work alongside the Polish F-16s that deployed there on 1 December 2021 to conduct Baltic Air Policing. The US F-15s landed at Amari to integrate with the current detachment of Belgian F-16s; both detachments will execute the enhanced Air Policing mission.”
