The UK has signed a contract with Elbit Systems UK for up to 130 ground-based surveillance radars. (Elbit Systems UK)
The UK will receive new ground-based surveillance radars (GBSRs) to bolster its front-line threat-detection capabilities following a contract signed with Elbit Systems UK.
Under the contract, Elbit Systems UK will deliver 90 GBSR systems between 2023 and 2024, with an option for an additional 40 systems, the company announced on 23 May.
The portable GBSR systems are designed to detect, track, and classify targets moving on or close to the ground using digital signal-processing capabilities. The UK will receive customised radars fitted with an optimised stabilisation unit and capture software to allow operator performance to be analysed. Open-architecture software upgrades will also be installed to facilitate integration with existing and future Ministry of Defence (MoD) systems.

The quantum accelerometer has been developed by Imperial College London. (Imperial College London)
A prototype quantum sensor device developed by Imperial College London completed the first period of at-sea testing onboard the UK Royal Navy (RN) trials and experimentation vessel XV Patrick Blackett .
The experiment is seen as a potential first step in understanding the application and exploitation of quantum-enabled navigation, which could provide significant navigational advantages when operating in environments where global navigation satellite systems (GNSS), such as Global Positioning System (GPS), are degraded or denied.
The quantum sensor developed by Imperial College London is a type of accelerometer. While conventional accelerometers are used in many different devices such as mobile phones and laptops, these sensors cannot maintain precise accuracy over long periods of time without an external reference to correct ‘drift'.

Turkey's Havelsan will equip the Indonesian Navy's new Arrowhead 140 frigates with its Advent combat management system (CMS), the company told Janes at the Langkawi International Maritime and Aerospace (LIMA) Exhibition 2023 in Malaysia.
The frigates are being constructed by state-owned Indonesian shipbuilder PT PAL, with steel cutting of the first ship in December 2022.
The Arrowhead 140 is the third different class of Indonesian warships planned to be equipped with the Advent CMS. Other classes include 90 m offshore patrol vessels (OPVs) under construction at PT Daya Radar Utama and KCR-60M missile craft built by PT Tesco Indomaritim.
UK defence group Babcock signed a design licence agreement with PT PAL in September 2021, which supported the build of two Arrowhead 140 frigates at the Indonesian shipbuilder's facilities in Surabaya. The Arrowhead 140 is based on the Iver Huitfeldt-class frigate design previously developed for the Royal Danish Navy. The project has been locally branded as the ‘Red White' frigate programme.

Inflatable Leopard 2A4 tank decoys are being supplied to Ukraine, Janes learnt at the International Defence and Security Technology Fair (IDET) 2023 held in Brno, Czech Republic, from 24 to 26 May. At the show, Czech-based company Inflatech displayed Leopard 2A4 and Czech STARKOM communication jammer inflatable decoys.
The decoys are designed to deceive and mislead an enemy by simulating objects and for use in electronic warfare training. The Leopard 2A4 decoy weighs 44 kg and the STARKOM decoy 35.2 kg. Their optical granularity is 0.2 m, thermal granularity is 0.6 m, and electronic granularity is 4 m, according to Inflatech. The company claims that they appear to an RQ-20 unmanned aerial vehicle as a real object from approximately 1,500 m.
The decoys can be inflated by a 150 ccm four-stroke petrol or diesel engine and take two people 10 minutes to deploy or pack. It is stable in winds up to 15 m/s, according to Inflatech.
