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.
There's actually a famous instance of it happening. K-19. They had to go into the reactor room to fix up the cooling because of botched manufacturing process.
What happened to them after can only be described as gruesome. I'd rather a bullet to the brain after.

Any accidental reflection, or visible detail that could identify people in the background or time the photo, could give the Russian police enough information to track down the photographer.
