PIT-Radwar presented the OSU-35K naval weapon system for the first time at MSPO 2022 in Kielce.

The OSU-35K is armed with the 35 mm calibre AM-35K automatic cannon – a licenced version of Oerlikon's KDA cannon – and features a dedicated opto-electronic tracking sensor. The system is capable of engaging both naval and aerial targets with various types of ammunition.

The prototype OSU-35K is under factory trials and is scheduled to be mounted onboard the Polish navy's mine countermeasures vessel (MCMV) ORP Albatros (602) later this year.

During the factory tests, the OSU-35K engaged aerial targets at a maximum distance of 5,500 m and an altitude of up to 3,500 m, with a rate of fire of 550 rounds per minute. The weapon is dual-fed from two magazines, with a capacity of 100 rounds each. Frangible armour-piercing discarding sabot (FAPDS) and programmable air-burst munition rounds can be used, with the gunner able to switch between types. Janes

The Japan Maritime Self-Defense Force (JMSDF) has demonstrated its ability to engage in enhanced co-operative ballistic missile defence (BMD) operations by test-firing two sea-based variants of the SM-3 interceptor.

The firings were carried out by the Maya-class destroyers, JS Maya and JS Haguro, in waters near Hawaii on 16 and 19 November, respectively, the service disclosed in a statement on 21 November.

Maya deployed an SM-3 Block IIA interceptor while Haguro launched the Block IB variant of the same weapon. Both firings were supported by the US Navy (USN) and the US Missile Defense Agency, the JMSDF statement added.

The SM-3 is a family of interceptors that has been developed by Raytheon to destroy short- and intermediate-range ballistic missiles. The weapon system utilises its own kinetic energy instead of an explosive warhead to destroy targets as part of its ‘hit-to-kill' method.

The UK Ministry of Defence (MoD) has completed the first trials of a high-powered, long-range Laser Directed Energy Weapon (LDEW) testbed at the Defence Science and Technology Laboratory's (Dstl's) Porton Down range in Southern England.

Conducted in October, the trials involved firing the DragonFire LDEW capability demonstrator at several target sets. Led by MBDA UK, the UK Dragonfire consortium includes Leonardo and QinetiQ as key technology suppliers.

The sovereign LDEW capability demonstrator programme has been established to improve the MoD's understanding of how high-energy lasers and their associated technologies can defeat representative air and surface targets at operationally relevant ranges, and in different operating environments. According to Dstl, the need to generate high levels of laser power and the ability to focus the beam with sufficient accuracy, are two important areas that need to be demonstrated to provide confidence in the performance and viability of LDEW systems. Other considerations include management of power and cooling demands over a prolonged period, and effects management/safety aspects.

The Iranian military unveiled the longer-range Sayyad 4B surface-to-air missile (SAM) for its Bavar-373 air-defence system on 6 November.

The missile was unveiled during a ceremony attended by Minister of Defence Brigadier General Mohammad Reza Ashtiani and Islamic Republic of Iran Air Defense Force (IRIADF) Commander Brigadier General Alireza Sabahifard.

The Iranian media reported that the missile has successfully engaged a target at more than 300 km during a test, up from the 200 km earlier achieved. It was also reported that the missile's maximum altitude has been increased from 27 to 32 km.

The Bavar-373 radars have also been improved, and during the test detected the target at a distance of 450 km, up from 350 km, and tracked it at 405 km, up from 260 km.

The Tasnim News Agency quoted Brig Gen Sabahifard as saying that the target drone was destroyed at an altitude of 40,000 ft (12.2 km).
