These two regiments formed a Super Heavy Artillery Group which acted as a holding unit. They were assigned to Army Group Royal Artillery as required. The 240mm howitzer. These large howitzers were well thought of but were relatively little used. This was partly because there was little opportunity to deploy siege artillery and partly because tactical air power did the job better. It fired a 360lb shell Maximum range was 25,225 yards. A reduced charge was available which gave a maximum range of 8,450 yards. Maximum elevation was 65 degrees Traverse was 20 degrees either side The 8” gun Very few of these big guns were made and issued. They were not very accurate and the wear on the barrel was excessive. It fired a 240lb shell Maximum range was 30,315 yards using Normal Charge 35,635 yards using Super Charge 8,450 yards using Reduced Charge Maximum elevation was 50 degrees Traverse was 20 degrees either side The 8” gun and the 240mm howitzer used the same carriage. Both guns were so heavy that it had to be broken into two loads, each with its own transporter. The barrel and recoil system were carried on one carriage and the trail on the second. Each was towed by a M6 38ton fully tracked tractor. Fully loaded each carriage weighed some 50,000 lbs. The tractor was the Tractor, High Speed, 38ton M6. In fact the high speed was to distinguish it from agricultural and construction type tractors. Maximum speed was 21 mph. It was however a powerful tractor, using two Waukesha 6 cylinder petrol engines of 817 cubic inches capacity each. Fuel consumption was o.3 miles per gallon. It carried a crew of eleven and fourteen rounds of ammunition. Further ammunition was carried on the three 6 X 4 or 6 X 6 Heavy Artillery Tractors per gun. These were Scammell Pioneer (6 X 4), Albion CX22 (6 X 4) or Mack NM (6 X 6). The mobile crane was Crane, Truck Mounted, M2 (Lorraine 6 X 6) which towed a trailer carrying the clamshell excavator. As a crane it lifted the carriage and barrel loads from the transporter and emplaced them. As a clamshell excavator it dug the pit which was needed to allow the breech to recoil at high elevation, and to accommodate the recoil spades. Guns could be emplaced without the crane by using the winches on the various tractors plus a lot of manpower. This required at least eight hours hard work against two hours with the crane.
