Assessing Tillman III's underwater protection

Did Tillman III sacrifice torpedo protection to achieve its armament and 30-knot speed?

It had a layered protection scheme, but whether that scheme was adequate for so large and valuable a ship is doubtful.

The drawings show layered underwater defence, so the concept was not devoid of torpedo protection. Whether the system would meet the standard expected of such an expensive ship remains doubtful. A weakness below the waterline would expose an exceptional concentration of money, guns, and displacement to torpedo attack. The design contains a real defensive scheme, but its adequacy is one of the super-battleship's largest risks.
