US Navy tests second-stage SRM for hypersonic weapons

by Robin Hughes

The US Navy (USN) Strategic Systems Programs (SSP) on 26 August announced that it had conducted a ground test of the second-stage solid rocket motor (SRM) booster in support of the navy's Conventional Prompt Strike (CPS) offensive hypersonic strike capability and the army's Long-Range Hypersonic Weapon (LRHW) development.

The test, performed on 25 August in Promontory, Utah, included firing the first stage of the newly developed booster, as well as the thrust vector control system on the SRM. This was the initial live-fire test of the second-stage SRM and follows a successful test of the first-stage SRM on 27 May, the navy said. The 34.5 in (87.6 cm) two-stage booster will be combined with a Common Hypersonic Glide Body (C-HGB) to create a common hypersonic missile for both services.

Hanwha Aerospace is building a new factory to produce engines for combat aircraft, including the Korea Aerospace Industries (KAI) KF-21 Boramae 4.5-generation aircraft. The new factory is also expected to support the development of South Korea's new domestic fighter engine programme.

Ground was broken for the 16,530m 2 engine production facility at Changwon on 15 April 2024, the South Korean Ministry of National Defense (MND) said on 17 April. The factory is being developed at a cost of USD30 million and is scheduled to be operational by 2025. The MND added that the factory's priority is the licence production of the 92.1 kN (20,700 lb st) General Electric F414-GE-400 engine for the KF-21.

A Hanwha Aerospace spokesperson told Janes on 19 April that “100%” of the licence manufacture of the F414 engine will be achieved at this factory. “The facility is expected to produce approximately 300 engines annually [after becoming operational], the spokesperson added.

The Venezuelan military confirmed on 16 April that it has the CM-90 export version of Iran's Nasir anti-ship missile (ASM).

Defence Minister Vladímir Padrino López inaugurated what a defence ministry statement described as a workshop for the CM-90 at Base Naval CA Agustín Armario in Puerto Cabello as part of the Bolivarian Navy of Venezuela's (ABV's) anniversary celebrations on that day. It released photographs and a video of Padrino inspecting several ASMs and associated containerised testing equipment inside a building.

The Nasir was developed from the Nasr missile, which is Iran's version of the Chinese C704, with the solid-propellant motor replaced by a turbojet engine and a launch booster. Iranian export documentation says this makes the CM-90 88 cm longer than the CM-35, the export version of the Nasr, and increases its range from 35 to 90 km.

The Netherlands Ministry of Defence (MoD) and Dutch Naval Design (DND) have joined forces to develop an unmanned surface vessel (USV).

Announcing the partnership on 12 April, the MoD said the USV will be designed for deployment from the future anti-submarine warfare frigates (ASWFs) currently under development.

Under the terms of the contract, signed on 10 April, the USV is planned to be completed in around four years, the MoD said. The 12 m long vessel will be “technologically very advanced, sustainable, autonomous, and operationally flexible”, it added.

The Belgian and Dutch navies are procuring two ships each to replace their respective Karel Doorman (M)-class frigates under the ASWF programme. The ships are being designed and built by Damen under a contract awarded by the Dutch Materiel and IT Command (COMMIT) in June 2023. Under the terms of the contract, the first frigate will be delivered to COMMIT in 2028 and handed over to the Dutch navy in 2029, while the Belgian Navy will receive its first ship in 2030.
