“How hard is it to change batteries in a sub?” “It’s a nasty, heavy job. I mean, you don’t need special machinery or anything. We do it with Tiger Teams, and it takes something like three or four weeks. Ivan’s subs are designed with larger battery capacities than ours, and also for easier battery replacement—they’re supposed to go through their batteries faster than Western subs, and they compensate for it by making replacement easier, hard-patches on the hull, things like that. So for them it’s probably an all-hands evolution. What exactly are you getting at, Bob?”
