Russia has developed naval version of its AU-220M 57 mm remotely operated weapon station

According to information released by the Russian Press Agency TASS on July 20, 2020, Russia’s Burevestnik scientific-and-research Institute (a subsidiary of Rostec’s concern Uralvagonzavod) has developed a marinized variant of the AU-220M 57 mm remotely operated weapon station (ROWS), Director General of Burevestnik Georgy Zakammenyh told TASS on July 20, 2020.

“We have developed a naval variant of the [AU-220M] 57 mm artillery station on the base of the Derivatsiya-PVO program. The specialists of the [Russian] Navy [VMF] positively evaluate its potential integration onto small surface combatants, including small ships and boats,” said Zakamennyh.

According to him, the baseline Derivatsiya-PVO 57 mm self-propelled anti-aircraft gun (SPAAG) will be converted into a robotized AA asset. “[High] level of automation and firing, remote control from automated workseats in the vehicle’s hull, and a cutting-edge optical-electronic station have almost brought the combat vehicle of the Derivatsiya-PVO system to the level of a robotized artillery system,” said Zakamennyh. Such a system will integrate combat vehicles, ground and unmanned aerial reconnaissance vehicles, fire-control units, and remote firing platforms. “We should modify the combat vehicle for operations in unmanned mode, create protected command-and-control lines, and update software. There is a large piece of work to be done, including the development of new-generation indigenous electronics,” said Zakamennyh. According to him, the Derivatsiya-PVO SPAAG has already entered the final stage of its trials.

The baseline AU-220M ROWS weighs 3,650 kg (with a gun mount) and is armed with a 57 mm automatic cannon and a 6P7K 7.62 mm coaxial general-purpose machinegun (GPMG). The main gun’s ammunition load comprises 80 armor-piercing (AP), high-explosive fragmentation (HE-Frag), and guided artillery (GAP) projectiles. The weapon produces a rate of fire of 80 rounds per minute and engages ground targets at a distance of up to 14.5 km. The GPMG carries an ammunition load of 500 7.62 mm cartridges. The module’s frontal armor provides Level 5 STANAG 4569 protection against 30 mm rounds; the station also features Level 3 STANAG 4569 all-round protection against 7.62 mm bullets. The AU-220M’s sensor suite comprises a TV camera, a thermal imager, and an independent dual-axis field-of-view stabilizer. The module is also fitted with laser rangefinders.

The Burevestnik delivers the A-190-01 100 mm naval gun to the Navy. “Since 2012, we have been delivering the A-190-01 naval gun to the servicemen of the Navy. This system was designed to replace the AK-176 gun that was the most numerous naval artillery system in service with the Navy,” said Zakamennyh. The performance of the A-190-01 gun dramatically exceeds that of its predecessor, he noted. “We have constructed and delivered to the Navy more than 30 A-190-0s1: however, our manufacturing capacities drastically exceed this level,” said the director, adding that new GAPs for the A-190-01 will be developed in a short-term prospect.

According to the official portfolio of the Burevestnik, the A-190-01 100 mm naval gun is intended for surface combatants with a displacement of more than 500 t. The artillery system produces a rate of fire of 80 rounds per minute and a firing range of more than 20 km. The gun’s ammunition load comprises 80 ready-use projectiles.
