I just dont get why they are so interested in keeping the team dry. They are going to get wet anyway, they have to breath air transported on the sub anyway, the water in the cabin can be warmed to reduce stress, and they certainly already have wet communication ability. So why build a sub that is tons heavier and much slower than a wet delivery sub? --Doug J

Doug, I think you gleaned more from the article and photo than I did! So the cockpit is centered, huh.

This new competition with Rand sounds like a follow on to the cancelled ASDS mini-sub program. The SEALs wanted a better vehicle than their old wet SDV. Maybe the ex-SEALs in the PSUBs group have some non-classified comments. Things they could tell us without killing us afterwards.

Paul: Thanks for posting this. I of course think it's the neatest thing since sliced bread. I wish there were more details available. With their experience, team effort, commercial goal, and financial backing it will be very exciting to see what they achieve.

As flattered as I would be to think they took any ideas from my design, I doubt that happened as I am always looking for the low cost approach and focused on maintained good downward vis and low submerged speed. Perhaps the North Koreans will be interested in my low cost approach? Maybe I can sell a version to the Navy for interception practice? :)

Their cockpit looks to be centered which just makes sense if you're looking to deliver a SEAL team. I do think they have over done the hype; a surface planing submersible as important as the helicopter? Ha! And besides the SEALS already have a surface planing submersible, it's just wet. I really don't see any real benefit in building a craft that will deliver the SEAL team in a dry environment when they will inevitably have to enter the water to make land fall. I do bet they can sell some as rich boy toys.

I'd be interested to know what you and others think.

Reynolds Marion, and team, building a sub for possible military or commercial use. From the little description in this article I'd guess they took a page or two from Doug Jackson's design: "marries a speedboat and a submarine".
