Microflown Avisa applies 3D shockwave detection for improved counter-artillery capability

Microflown Avisa and Leonardo have developed new acoustic artillery detection technologies, briefing on these at the 2022 Omega Future Indirect Fires conference in Bristol.

Microflown Avisa has developed a new concept based on detecting the 3D shockwave (SW) generated by an artillery round – which originates at the tip of the shell along its trajectory – and the muzzle blast.

The company's Acoustic Multi-Mission Sensor (AMMS) detection system detects muzzle blast alone, and is based on micro-electromechanical systems (MEMS) and measures acoustic particle velocity. It consists of two orthogonally placed Microflown transducers and a microphone in a single hemispherical container.

Each AMMS provides the direction and elevation of the sound source; networked together these can provide accurate localisation. Earlier versions of the system have been used operationally and include both static networked sensor arrays and single vehicle or UAV-mounted sensors.

Babcock and IAI to collaborate on radar for UK Serpens project

Babcock is to collaborate with Israel Aerospace Industries (IAI) and subsidiary Elta Systems to offer a deep-find radar solution for the UK Ministry of Defence (MoD) Serpens programme.

According to a Babcock announcement on 11 August, the company signed a Memorandum of Understanding (MOU) with IAI and Elta Systems to offer IAI-Elta's Compact Multi-Mission Radar (C-MMR) system for the Serpens programme.

A Babcock official was unable to provide further comment on the MOU at the time of publication.

The C-MMR system is intended for air defence and artillery weapon-location missions, the announcement said.

Babcock noted that the MOU will help establish their system integration and through-life support while also developing its radar assembly and maintenance expertise.

Project Serpens, a British Army programme, seeks a new weapon-locating radar system. A request for information announced in October 2019 detailed that the new system would involve a suite of networked sensor systems to detect, acquire, track, and assess adversary indirect fire threats, including mortars, artillery, and rockets at “vastly increased” ranges compared with the current fielded systems.

US Navy receives first next-generation Growler jammer pods

by Gillian Rich

The Next Generation Jammer Mid-Band (NGJ-MB) fleet representative pods were delivered to the US Navy in July 2022. The pods are part of a system that will eventually replace the Boeing EA-18G Growler's ALQ-99 system. (US Navy)

Raytheon Intelligence & Space recently delivered its first ALQ-249 Next Generation Jammer Mid-Band (NGJ-MB) pods to the US Navy. The jammer pods are part of a system that will eventually replace the Boeing EA-18G Growler's ALQ-99 Tactical Jamming System.

Raytheon delivered the pods to the Naval Air Warfare Center Aircraft Division (NAWCAD) Patuxent River, Maryland, on 7 July, the service announced on 8 August. The pods will be used to complete the jammer's developmental test programme and start the operational test programme, the navy said in a statement. Initial operational capability (IOC) is scheduled for the second half of 2023.

The NGJ-MB has more power than the Growler's ALQ-99 and the ability to target multiple systems, said Lieutenant Alexander Belbin, project officer with NAWCAD's Air Test and Evaluation Squadron (VX) 23.

USMC explores operational use of low Earth orbit satcom

The US Marine Corps (USMC) displayed a variety of emerging communications equipment during the amphibious warfare phase of the Rim of the Pacific (RIMPAC) exercise in Hawaii this week.

The display was hosted by the first Marine Littoral Regiment (MLR) to join the USMC's order of battle – 3rd MLR – which is in the process of being equipped as a “self-deployable, multidomain force” that will support partners and allies in deterring adversaries, particularly across the Indo-Pacific.

3rd MLR's Communications Company highlighted several satellite communication (satcom) user terminals, used to network ground vehicles, surface vessels, and command posts to low Earth orbit (LEO) satellite constellations.

Commercially available LEO satcom is gaining popularity across armed forces around the world. Combat commanders see it as a way to employ primary, alternative, contingency, and emergency (PACE) communications plans, which can ensure secure and resilient connectivity, even in the face of disruption by well-equipped adversaries.
