"So you would stick a platoon of SEALs in here, 14 guys ... you fill this chamber with water until you match the outer sea pressure. Once the pressure in and outside the ship match, the hatch will lift off open, and they can swim out of a fully filled chamber into open ocean."Once there, the SEALs can retrieve any weapons or gear from the SOF box (which we saw being loaded into the tower in the first picture).
