[ Attachment: You are not allowed to view attachments ]
Russia has revealed a new 152mm gun, with two barrels, vertically stacked. Unlike the smaller Gast-type guns in Russian service (GSh-23, GSh-30, 2A38M) the mechanisms are not mechanically linked, but they are connected through the hydraulic recoil system, and fire alternately. This principle is called the 'boxer' system. It is being developed by the Federal State Unitary Enterprise (FSUE) TsceNII 'Burevestnik' in cooperation with public corporations NPO 'BTA', FSUE 'Uraltransmash', FSUE 'TsceNIIM', and FSUE 'Uralvagonzavod'.

This gun has initially been developed for an army SPG, based on the 'object 195' tank chassis and called the 'Koalitcia-SV' ('coalition'). In this form, the gun has a 50-round automatic loader (the turret is unmanned) and can fire at about 15-18 rpm. It is expected to enter service in 2007.

There is also a proposed naval version, possibly intended as a replacement for the AK-130. It is reportedly being developed by Arsenal (although that is not confirmed) and will use a 'stealth' cupola.
The range with existing ammunition is about 50 km, but NIIP is developing a new round capable of up to 70 km.
With thanks to Denis Evstafyev for this material.
Da li neko možda zna nešto više o ovom oruđu? Deluje vrlo zanimljivo.
