The AP-104 howitzer (Pelinese: АП-104) is a towed 155mm gun-howitzer manufactured by Yarimaka Artillery Foundry since 1999. It is currently the primary towed 155mm artillery piece of the Pelinese White Army, which adopted it in 2002 as a replacement for the AP-55. Two revisions (AP-104M and AP-104M2) have since been introduced to increase performance, reduce mass, and simplify construction.
History
Design
The AP-104 is a towed gun-howitzer design intended primarily for usage in the indirect fire role, with a limited direct fire capability using optical sights. It uses a much higher percentage of titanium and other low-density components in its structure than the preceding AP-55 howitzer design in order to reduce mass by 25% while also increasing the size of the gun barrel.
The cannon itself has a rifled barrel of 8.2 meters in length, a semi-automatic, vertically sliding breech for loading, and a conventional hydropneumatic recoil absorption system. The heavier barrel is 1.8 meters longer than the preceding AP-55 gun-howitzer and allows for increased range and rate of fire in the AP-104.
