The FH70 is a jointly developed British-West German-Italian 155 mm L/39 towed howitzer with an auxiliary power unit for limited self-movement. Ukrainian service made it a documented NATO-standard tube-artillery option alongside M777 and CAESAR systems, while Yemen reporting separately places Saudi FH70s among border artillery used during the war.
Ukrainian forces operated FH70 155 mm towed howitzers during the full-scale Russian invasion, with Ukrainian defense reporting identifying FH70, M777, and CAESAR already working at the front in May 2022 and the Tallinn Pledge later naming additional Estonian FH-70 donations.
Role detailsSaudi forces employed FH70 155 mm towed howitzers from the Saudi-Yemeni border area during the Yemen war, where reporting based on a 2018 French military intelligence note identified FH70s as active near the border.
Role detailsFH70, FH-70, and FH 155-1 refer to the same towed-howitzer family; some designations reflect national service or retrofit terminology rather than separate catalog weapons.
