I thought forum readers might enjoy this WWII era mortar on this 4th of July weekend. (Text and images obtained from globalsecurity.org)
The 36-Inch Little David heavy mortar is the largest gun ever built, beating the German Dora and Karl. The mobile mortar was capable of hurling a 3,650-pound projectile a distance of six miles. The giant mortar had a rifled, 22-foot, muzzle-loading tube which, with its firing mechanism and other parts making up the tube assembly, weighs approximately 80,000 pounds. The mortar's base assembly, on which the tube rests, is constructed like a huge box and weighs 93,000 pounds.
While traveling, the mortar's tube and base assemblies each make up separate tractor loads. A complete "Little David" unit also included a bulldozer and crane with bucket shovel to dig the emplacement. The huge mortar can be emplaced in 12 hours, while the largest (820MM) known German artillery weapons were hauled on 25 railway cars and required three weeks to put in firing position.
Wishing everyone a great 4th of July. Ya'll make some BOOMS, ya hear! :grin:
