British warship HMS Bangor is made of plastic ...

Maybe it's for defeating magnetic mines ?
Yeah, that must be it.

It's what smaller boats are made of. In this case it looks like the fiberglass is way too thin (to me).

Yeah its GPR.
Old saying about boats: "Glass is crass, but wood is good & steel is real"!:icon_lol:

Wasn't the airliner that lost it's door made of carbon fiber?

The Bangor is a mine sweeper and the fiberglass hull is, indeed, made to reduce the risk from magnetic mines.

That was a Boeing 737 Max 9. AFAIK they are aluminum. The 787 is mostly carbon fiber.

Yes "sweepers" used to be wooden for the same reason.

North Sea born D/E subs don't have enough ferrous metal in them to shoe a horse from my understanding. Plastic hulls, aluminum engines with titanium crankshafts, etc. Maybe the cranks are steel, but that's it. Bit deadlier than the Pentagon wants to admit.
