As sea turtles are air breathing reptiles, they need to surface to breathe. Sea turtles can hold their breath for several hours, depending upon the level of activity. A resting or sleeping turtle can remain underwater for 4-7 hours.

The only constraint on the time it can stay submerged is food for the crew. Once the food runs out it has to be re-supplied.A normal patrol can be between 3 and 6 weeks but could be extended to 12 weeks if necessary and if they had enough food for the crew, probably much longer.S Nuclear Submarines can stay submerged for only as long as they have food. That is what is the limiting factor. I have gotten underway walking on food. Large #10 can stacked 2 high throughout the forward compartment and that is just for starters. Needless to say, it can be a really long time!
