Could an SSN carry detachable underwater vehicles?

Could uncrewed underwater vehicles take the form of detachable submarine bulges?

That is considered doubtful, but independent vehicles could potentially attach to the hull sides and detach for operations.

Making an uncrewed vehicle part of a detachable bulge is considered doubtful. An alternative would attach independent vehicles along the outside of a nuclear submarine's hull. The imagined boat could carry two, four, or six depending on its length and release them near the operating area. This remains a possible future arrangement.
