The AK-630M-2 Duet is the most modern upgraded version of the famous Soviet naval cannon AK-630


Recalling the AK-630, this is a fully automatic Soviet and Russian weapons system based on a six-barrel 30 mm rotating gun. The AK-630 has been in service since 1976, and has since become the standard Close-in weapon systems of Soviet and Russian warships.

The AK-630 is mounted in an enclosed automatic turret and directed by MR-123 radar and television detection and tracking. The system’s primary purpose is defense against anti-ship missiles and other precision guided weapons. However it can also be employed against fixed or rotary wing aircraft, ships and other small craft, coastal targets, and floating mines.



The AK-630M2 was introduced to the public at the IMDS-2007 international maritime show. It is exactly the modernized version of the AK-630M1-2.

Compared to the old variants AK-630M2 there are many differences in appearance. Especially the turret, has an angular structure instead of the round tower of AK-630, AK-630M and AK-630M1-2. This design reduces the radar cross-section significantly compared to traditional AK-630 mounts. This new design is consistent with the stealth design of the new Russian warships.

AK-630M2 Performance

The super-speed naval close-in weapon system AK-630M2 Duet has a weight of 2.5 tons. The power of the AK-630M2 Duet is 2 x 30 mm 6-barrel automatic cannon AO-18, the distance between the two guns is 320 mm.

The cannon has the ability to adjust the rate of fire from 4,000 r/m up to 10,000 r/m. Maximum range of 8,100 m, effective range for ground, water and aerial targets is 4,000 – 5,000 m.

Radar and Electronic system

The AK-630M2 Duet is integrated with the Vimpel-AM2 firing control system combined with the MR-123AM2 and MR-176M2 radar. It is also equipped with the KM-11-1 laser rangefinder along with the LDM-1 Cruiser.

In one test, the AK-630M2 shot down a simulated anti-ship missile target at an altitude of 10 meters with only 200 rounds, a very respectable performance.
