Japan's Mitsubishi Heavy Industries (MHI) is set to deliver its first OZZ-5 mine-countermeasures (MCM) unmanned underwater vehicle (UUV) to the Japan Maritime Self-Defense Force (JMSDF).

Company officials told Janes at the DSEI Japan 2023 exhibition in Chiba that the first of five on-order OZZ-5 systems will be supplied to the JMSDF by the end of March. The initial five OZZ-5s are all expected to be delivered by the end of 2024.

MHI officials said the JMSDF will operate unmanned surface vessels (USVs) – also built by MHI – that deploy from the service's Mogami-class frigates. Janes understands that the OZZ-5 will be operated by the JMSDF around Japan's disputed southern islands.

The Japanese Ministry of Defense (MoD) initiated a project to develop an MCM UUV in the late 2000s, leading to MHI's development of the OZZ-5 in 2017. MHI said the development programme was completed in 2021.

KNDS's Nexter announced in a press release on 29 February that it had qualified its Shard 120 mm armour-piercing fin-stabilised discarding sabot (APFSDS) tank ammunition in late 2023 and that it is now ready for production.

The ammunition was demonstrated against rolled homogeneous armour with Leclerc and Leopard 2 main battle tank (MBT) users in Alcochete.

Shard is designed to defeat modern MBTs and future threats, with Nexter claiming it offers increased penetration, greater accuracy, and reduced barrel wear.

The company said the ammunition's penetration has been increased by 15% while keeping dispersion low; its barrel wear has been reduced by 25%, reducing maintenance cycles and costs; and its muzzle velocity is 1,720 m/s with the Leclerc L52 gun and 1,734 m/s with the Leopard 2 L55 gun.

The Bundeswehr has ordered Skyranger 30 air-defence systems mounted on Boxer armoured vehicles, Rheinmetall announced in a press release on 27 February. Under the EUR595 million (USD644.8 million) worth of contract, the prototype will be delivered at the end of 2024, followed by 18 production vehicles, with an option for 30 more.

According to the German company, the Skyranger 30 will be a key component of the Bundeswehr's Nah- und Nächstbereichsschutz (short- and very-short-range air defence: NNbS), for which a Rheinmetall Electronics, Diehl Defence, and Hensoldt Sensors Arbeitsgemeinschaft (ARGE) working group was awarded a contract in January. The turret will be equipped with a 30×173 mm KCE revolver gun firing programmable airburst munition, two Stinger surface-to-air missiles, and a sensor suite.

The Bundeswehr's Skyranger 30 order follows one from the Bundesheer (Austrian Armed Forces) on 21 February for 36 Skyranger turrets, with an option for nine more for Pandur Evolution (EVO) 6×6 armoured vehicles that Austria ordered from General Dynamics European Land Systems-Steyr (GDELS-Steyr) on 19 February.

US-based High Point Aerotechnologies showcased its latest-generation Sawtooth counter-unmanned aircraft system (C-UAS) for the first time at Singapore Airshow 2024 held from 20 to 25 February.

Speaking to Janes, the chief revenue officer of High Point, Evan Hunt, said the Sawtooth C-UAS uses layered technologies to adequately detect unmanned aerial vehicles (UAVs).

The system comprises a passive radio frequency (RF) system, radar, electro-optic/infrared (EO/IR) sensor, and jammers.

As a first step of detection, the Sawtooth uses the passive RF system to detect UAS communications in frequencies that are in known libraries. As the second step, in the case where the frequency is not known, the Sawtooth uses its radar.

“Usually, we use passive RF and radar to find the drone and then cue an EO/IR sensor that is looking in the mid-wave and the short wave, so it is day or night operable,” adds Hunt.
