History

In January 1939 a specification was issued for a gun to replace the 6 inch guns and howitzers in use. The first units were equipped with the new gun in May 1942, and the first actions were in the Western Desert. Initially the range was disappointing, but a new shell 20 pounds (9 kg) lighter solved the problem.


The 5.5 survived after the war until replaced by the FH-70 towed howitzer in service as L121.
