>But today, the version being built at a shipyard in Wisconsin shares only 15 percent commonality with the original design How is this in any way acceptable? The procurement strategy was to buy an existing design in order to speed up the process. I would bet tradeoffs were made doing it that way instead of a clean sheet design. Now, after the fact they throw away the design and make something new? The Navy is likely…
The other reason is that this program is constantly chasing a moving target. The national security establishment is getting increasingly freaked out about the risk of a naval war with China. The original inexpensive European frigate design was largely designed for lower threat environments, mainly European coastal defense against Russia plus gunboat diplomacy in Africa and the Middle East. Now the US Navy needs something that can fight and survive against a superior force in the Western Pacific, so many of the combat systems are getting upgraded. And even with those upgrades it's still dangerously short of VLS cells. If Navy leadership knew in 2018 what they know now then they might have chosen a different approach.
