T-155 Fırtına
From Wikipedia, the free encyclopedia
T-155 Fırtına (Turkish: Storm) is an indigenously-designed 155mm self-propelled howitzer produced by the Turkish Army, which shares many technologies with the South Korean K-9 howitzer.
The T-155 Fırtına has used some of the subsystems of the K-9; such as the German designed MTU-881 KA 500 power pack, the South Korean designed 155/52 caliber gun system and the ammunition feeding mechanism; all of which are also produced under licence in Turkey.
Even though the T-155 looks similar to the K-9, the Turkish howitzer has considerable differences in its turret design, navigation system and electronical systems (such as the radio and fire control system) which were developed in Turkey.
T-155 Fırtına has a maximum firing range of 30 to 56 km, depending on the type of ammunition. It can reach a top speed of 66 km/h and has an operational range of 480 km.
The T-155 are built in Adapazarı, 1st Maintenance Command of the Turkish Army. Production rate of the T-155 is 24 units per year. From 2001 to December 2006, 72 units have been delivered to the Turkish Army. A total of 350 T-155 Fırtına will be produced.[1]
