Why Hood's submerged launchers became an integration problem

Why did designers not foresee that Hood's machinery and speed would obstruct additional submerged torpedo tubes?

Specialists worked within separate sections, and the person responsible for the whole design did not force the integration problem to be resolved.

The difficulty is framed as an organizational failure in systems integration rather than a single unforeseeable technical mistake. Designers working on engines, speed, and submerged torpedo launchers could remain focused on their own sections. The ship needed someone at the top to combine those constraints and force an argument about how they interacted. Without that whole-ship review, machinery size and high-speed operating conditions could make later submerged-tube additions impractical. Hood becomes a compact example of why warship leadership must connect specialist work before decisions harden into the design.
