'Near the ground' as in by the coast? Surely, the 'ground' in the middle of the sea is called the sea bed, and if a submarine were to end up stuck on the sea bed I would suggest that it had sunk rather than 'run aground'.
Ahh, SUBMISS, SUBLOOK, SUBSUNK.
So just how long will SUBLOOK take without a LRMPA to assist in the looking?
Hand grenade, pin, throw, run....
