Does any one know why the tumble home hull was discontinued. Wikipedia says it has stability problems in turns and rough seas. The Zumwalt's prow is meant to go under waves. Has the ship been tested in rough seas?
- gk1 12y agoFormer naval architect here, used to work in the office that designed this thing (but it was before my time). They haven't entirely dismissed the tumblehome hull. For example, the LCS 2 has a hull that resembles a tumblehome (though it's not as drastic as the DDG-1000). Aside from the financial and mission capability issues, the novel design presented more problems than it solved... Which contributed to the cost overruns. Edit: With regards to whether the ship has been tested... Prior to the first one being completed, the most they could do is model testing.
- spydum 12y agoIf there is anything I have learned from working at a large enterprise shop, it's that bad decisions made early on, once found to be such, are next to impossible to change. People would rather try to "muscle" through it (throw $$, people, hardware, wellness efforts), rather than discuss a new design. I imagine it's always about 2x worse in a government shop, and another 2x worse for defense gigs.
