How long should it really take to reactivate the battleship in the film Battleship, and what steps would be required?
Short answerAbout ten days just to make the ship fueled and mobile, with boiler startup and absent shore support setting the pace.
NotesThe estimate begins with getting fuel aboard and bringing the steam plant back into operation. Without an external supply to help start the machinery, one boiler must be lit and used to bring the others online in sequence. The reply also distinguishes the fuel available in the film scenario from the need to preheat heavier fuel oil. An initial estimate of a week grows to roughly ten days for a fueled ship able to get underway. That estimate addresses propulsion and movement, with combat readiness left unresolved.
