Title: Sovjetski brodski protivavionski top 25 mm KZAU 2M-3M Post by: Bozo13 on April 11, 2015, 08:50:33 pm Nemam puno podataka, osim ovih na tabli, i u temi Torpedni čamci klase "Shershen" (https://www.paluba.info/smf/index.php/topic,545.msg317817.html#msg317817) postavljen je Shershen iz naoružanja RM Kambodže na kome je top AK-230 zamenjen 25 mm 2M-3M.

Quote This gun was based upon the 84-KM which was designed in 1943-44. The specifications for a new weapon were first developed in 1945 and then modified in 1947. Trials started in 1949 and the gun was accepted into service in 1953 as 110-PM. Manufacturing in the USSR continued until 1984. These guns were fed from 65-round belts and the early guns could also be fed by 7-round clips. The twin mount on which these guns were originally used was designated as 2M-3. At a later date, the mount was modified into 2M-3M version. In this later version, the automatics were converted to gas-operation and the firing rate was increased to 470 - 480 rounds per minute during trials. These guns were nominally rated as being air-cooled, but they were actually cooled with water from a special hose for at least 15 seconds during reloading.

Pouzdan top na lakom lafetu, korišćen na skoro svim lakim jedinicama VMF SSSR. Veći brodovi su već početkom 60ih dobili AK-230. Korišćen na brodovima 100tD i više. Posle 1945. zamišljen kao masovno oruđe zaprečne vatre PVO brodova, ali je ubrzo postalo jasno da bi bio neefikasan zbog male kadence i lakog zrna. Sličan japanskom Type 97 25mm (Hotchkiss), ali veće kadence.
