Liberty ships didn’t have nearly that much electronic. Heck your average Gold Wing motorcycle today probably has more electronics than a Liberty ship. The real question is how’d they let it get this bad. Months to rewire is a legitimate estimate, NEEDING to rewire is not.
I work next to Agoura road in Calabasas, CA. It is a side road along the Hwy 101 freeway. They are widening the road. Broke ground Nov 2014.
It is 2 years 4 months later and they are still working on it. Maybe 2 whole miles has been worked on with about a half mile not paved for months. The rest they are still grading. Backing up traffic at Kanan road and Agoura for months. (Malibu is several miles away down Kanan).
I suspect it would only take a few months to finish but they have to wait for the inspector....... or it is another brother-in-law project. BTW the city council rejected putting in a 8” water pipe as too expensive. They will install at a later date! when it will be more expensive as they - you guessed it! They will tear up the road to install it!
Liberty ships were built in large subsections. If we use some ingenuity I’m fairly confident with the right preplanning large modules could be created to expedite the matter.
