The 7.2" Howitzer

7.2

After Dunkirk there was a great shortage of heavy artillery so requests for a weapon of around 8" in calibre with greater range than the current 8" Howitzer were made. Firing trails were conducted to see how much stress the 8" Howitzer carriage could take and so it was decided to develop a 7.2" weapon that fired a 200lb shell at 1,700fps. Barrel liners of existing 8" weapons were replaced by a 7.2" liner
