Development The naval 30 mm AK-630 Kashtan Close-In Weapon System (CIWS), was developed during the late 1960s and entered service in 1969. It is an electrically driven Gatling-type revolving barrel weapon controlled by a ship's central fire-control system. The AK-630 reportedly has a rate of fire between 4,000 and 5,000 rds/min. The 30 mm AK-630 is known to be in service with
India , Cuba and former Warsaw Pact nations, including Poland , Romania and the Russian Federation and Associated States (CIS). There is also a 30 mm AO-18L rotary gun with a rate of fire reduced by 750 rds/min to 1,000 rds/min. This version is used on the AK-306 naval mounting. Description The 30 mm rounds fired from the AO-18 gun are fixed and fired at a nominal muzzle velocity of 900 m/s. A single wide copper drive band is used with the projectiles crimped into the rimless steel cartridge cases by two rows of spaced crimpings engaging in cannelures on the projectile. Each case has a special tropic-proofed protective coating. The 6/7 FL pyroxyline powder propelling charge weighs 117 to 118 g and is initiated by an electrical primer.

HE-I For this round the projectile is known as the UOF-84 (or VOF-84) and weighs 390 g - the round itself is also referred to in some instances as HEFI. The streamlined projectile has a nose-mounted MG-32 all-weather point detonating fuze with a self-destruct element functioning approximately 16 seconds after firing. It contains 48.5 g of explosive. HE-T Described as a high explosive fragmentation shell (FT or FRAG-T), the projectile for this round is the UOR-84M (or VOF-84M), weighing 386 g. The filling is 115 g of A-IX-2G, The MG-32 point detonating fuze is retained and the primer is the EKV-30M. The projectile has a distinct waist just forward of the drive band.
