Submarines also suffering delays, but current USN subs still have enough lead enough that SSNX isn't urgent as updating surface combatants as long as current sub fleet is replaced at relative parity. I don't think there's secret fleet, dry docks are easy to monitor. Maybe some XLUUVs, that can be built in an enclosed plant and shuttled around. I think more trying to figure out naval unmanned platforms, to see what future fleet composition will be, i.e. navy Force Design 2045 wants 370 manned ships, 150 unmanned, maybe better off with 300 manned and 200 unmanned.
