Monitor Speedboat Lands War Tanks Under Fire (May, 1938)
It seems like this boat would need to have an amazingly fast ballasting system to prevent just flipping over when the tank rolls off. Not to mention, with the tank on top it would be crazily top-heavy.
Monitor Speedboat Lands War Tanks Under Fire
DESIGNED to land a war tank ready for action, from a ship that may be several miles offshore, a unique forty-foot armored launch has been constructed at Portsmouth, Va., for tests by the U. S. Navy. Bearing the vehicle upon its flat, monitorlike deck, the speedboat may be driven right up on the beach without damaging its propellers, and the tank crawls ashore. The boat then backs off for another load, defending itself with a pair of machine guns in its steel-sheathed conning tower.
