The contractor will charge the government twice for building the ship, and make a killing off construction.
The Navy should give it back to the contractor, and not pay a cent, or ask the contractor to pay back in full any money that the government has paid the contractor on this.
There should be penalties, not rewards, for doing the job wrong.
Welding titanium has long been known to require a special process of removing oxygen from the environment. The contractor cannot plead ignorance on this...
And while all this is happening, the Navy/Marine Corps team will do the job with the Austin Class LPD-4 ships, built in the early 1960's.
So much for planning ahead.
