As reported by SavunmaSanayiST on February 11, 2025, the Turkish Land Forces will receive a total of 140 Firtina-II 155mm self-propelled howitzers, as part of a scheduled modernization program. At least ten of these vehicles have been delivered so far, with future upgrades incorporating the domestically developed UTKU power group. The transition to national components is intended to reduce reliance on foreign suppliers.
The T-155 Firtina, a self-propelled artillery system based on South Korea’s K9 Thunder, has been in service with the Turkish military since 2004. Developed through a technology transfer agreement with South Korea, the Firtina features a modified turret with increased ammunition storage and a fire control system adapted for local operational requirements. The system has undergone continuous improvements.
The Firtina-II introduces several modifications, including an electrically powered turret and barrel positioning system, an automatic ammunition loading mechanism, and the integration of the SARP Remote-Controlled Weapon System (RCWS). Additional changes include an upgraded fire control system, climate control, and an automatic fire suppression system. The vehicle retains a fully welded steel armor hull designed to withstand 14.5mm caliber small arms fire and artillery shell fragments.
