This course teaches the students how to dive the MK-16 mixed gas dive rig and to pilot and navigate the MK-VIII SEAL Delivery Vehicle. The SDV is a "wet" submersible operated by SEALs to either conduct 100% long range submerged missions or to clandestinely deliver SEALs and other agents onto enemy territory from a submarine or other vessel at sea. It takes a formidable amount of training to be able to pilot and navigate the SDV well, and the best SDVers usually stay at an SDV Team for the bulk of their SEAL careers. We discuss the SDV more in the equipment section of this site. Since this training is highly technical and very dangerous, it is considerably more relaxed and is a refreshing transition for the BUD/S graduate from the harassment of BUD/S training to the professional attitude at the SEAL Teams. Still it is expected that you perform at a high level; it is not unheard of to be expelled from this training. Also the new SEALs reputation starts while he is at BUD/S, and reputation is the cornerstone of the professional SEAL's career. To be known as a good "operator" is as highly coveted in the Teams as a six figure paycheck is on Wall Street! Many aspects of the SEAL Delivery Vehicle program are classified and beyond what we can discuss here - so you will have to join the Navy to find out.
