If it’s considered repairable, it’s probably 2 years+.
The USS Ross is looking at almost two years for much needed maintenance repairs all over. 18 months on major repairs is generally considered rapid.
But, based on history, they’ll go cheap with as many shortcuts as possible, so it’ll be reactivated sooner than expected but sink a few months later, by its own accord. Obviously damaging the environment with it, or some other dramatic fuck up to deal with on top. It’s the Russian way.
