According to American Friends Service Committee: "UK company BAE Systems manufactures the M109 howitzer, a 155mm mobile artillery system that the Israeli military has been using extensively, firing tens of thousands of 155mm shells into the Gaza Strip. Some of these shells are white phosphorus bombs, the use of which is forbidden in densely populated civilian areas and potentially amounts to a war crime. BAE also manufactures electronic missile launching kits and other components for Israel’s F-15, F-16, and F-35 fighter jets, which the Israeli Air Force has used extensively in all of its attacks on Gaza, including in 2023."
