Atlas Elektronik UK (AEUK) and Raytheon have teamed to demonstrate an autonomous mine hunting solution based on the AEUK Atlas Remote Capability Integrated Mission Suite (ARCIMS) unmanned surface vehicle (USV) to the UK Royal Navy (RN).
The two companies have integrated Raytheon's AN/AQS-20C mine hunting sonar system with an ARCIMS USV for participation in the forthcoming Wilton Industry Show and Experiment for Mine Counter Measures (WISEX) demonstration in the Clyde approaches. Scheduled to start in mid-October on ranges off Campbeltown, WISEX is a capability showcase intended to allow industry to demonstrate candidate systems and technologies for the RN's Mine Hunting Capability (MHC) Block 2 programme and/or future spirals.
Towed behind a USV, the AN/AQS-20C incorporates four separate sonars in a compact, lightweight, and hydro-dynamically stable towed body. These comprise a synthetic aperture sonar covering a broad swath either side, a forward looking sonar for volume search through the water column, and a nadir gap-filling sonar looking beneath the towed body.
DSEI 2021: Fabrique Nationale displays FN EVOLYS LMG for first time in UK

Fabrique Nationale (FN) Herstal displayed its new FN EVOLYS light machine gun (LMG) at DSEI 2021 on 14 September, marking the first time the weapon was displayed in the UK.
Kristof Verjans, one of FN's demonstration team, showcased the self-correcting lateral feed system of the EVOLYS, which eliminates any risk of the weapon being improperly loaded by a user under stress, with the feed tray designed to work with the feed cover to push the rounds into the correct position and retaining them with spring loaded brackets.
Verjans also demonstrated the new hydraulic buffer system, which is integrated into the working parts of the weapon, departing from previous FN machine gun designs where the buffer was part of the rear of the receiver. The buffer, like the feed system, is also self-correcting and self-regulating, automatically maintaining a constant rate of fire regardless of the calibre the weapon is chambered in or how long the weapon has been firing.

TDW GmbH, a subsidiary of MBDA Germany, publicly displayed its Automated Anti-Tank Weapon (PARM) for the first time at the DSEI show in London on 14–17 September, marking a de facto relaunch for a system that was developed in the 1980s.
The company displayed a PARM 1 with a mock-up infrared (IR) sensor fitted to a new accessory rail to show an alternative way of triggering the off-route mine, which is normally initiated when a vehicle crushes a fibre-optic cable strung out across its path or manually using a command wire. The IR sensor would enable it to be programmed so that it allows a pre-set number to pass by before it fires.
Christoph Schwarz, TDW Business Development Marketing & Contract representative, told Janes only prototypes of the IR sensor have been developed so far. Concepts for radar, magnetic, and seismic sensors are also being worked on, he added. TDW developed similar concepts in the 1990s, such as replacing the fibre-optic cable with a combination of an acoustic and a passive/active IR sensors.

The US Missile Defense Agency (MDA), in association with Boeing and Raytheon Technologies, on 12 September conducted a test launch of a Ground-Based Midcourse Defense (GMD) Ground-Based Interceptor (GBI), flying a mock-up of the Exoatmospheric Kill Vehicle (EKV), with a three-stage booster operating in a two-stage mode.
The milestone test – in which the third stage was not ignited – demonstrates a new capability for the GBI, allowing it to release the EKV earlier in flight and, accordingly, enable an earlier opportunity to intercept and defeat a missile threat. The MDA designates this new capability as “a 2-/3-Stage selectable GBI”.
