Hmmm....is it because the S201 has windows and meanwhile the Teledyne doesn't? Maybe the Navy wants something more rug-id to withstand all the pressures and communications systems that are vital?

Well, the Commeroical sub is actually the S301...my apologies, a fat fumbled finger mistake on my part.

Anyhow, the commercial standards are singificantly less rugged, less secure, and less capable of taking damage than a military standard. They do not expect people to intentionally shoot at them and try to sink them.

So, I think if they ever actually select the S301, they will make a militarized variety of it to upgrade some of those things. They believe however, that that may still be significantly cheaper than designing one from scratch.

SD's own NavyReco had a great write up on this:

Jeff I was not saying they are a replacement for a mini sub but a assistant to them. The range is just a handful of miles. And the diver would still have his fins. Basicly they move closer to shore but can keep the minisub at a stand off of a few miles jet the rest rest of the way to the target.

Okay...I got ya.

So, they take the SEAL dry delivery mini-sub in close, then when a couple of miles...maybe even less...off shore use these devices to come the rest of the way in.

Makes very good sense to me for whatever missions would allow for that type of ingress. Heck, I suppose they could carry inflatables in the mini-sub and come in on those too if necessary, when they had to carry more equipment.

I will just be glad when they have an honest to goodness operational, and proven dry submersible that can carry them many miles into the shore.

Yup that was my thinking. It would keep the dry sub away from potential discovery. And navy reco's story does mention the ability to carry inflatable boats. As to the DSRV didn't the navy only build 2 Mystic class with one mothballed?

SS-N-14 (Metel or Rastrub) on Udaloy is one of the weirdest naval weapons in use :D :

Let me add this: There's a scheme of this weapon in one of pop-up windows on that Russian page; I downloaded it and practiced translating from Russian to English (I'm not good in that! :)

JHSV%201%20Builders%20Trials%20-%20Bow.jpg

World Maritime News said:
The future USNS Millinocket (JHSV 3), returned to the Austal USA shipyard on Dec. 13, in Mobile, Ala. after successfully completing builder’s sea trials. Successful completion of builder’s trials marks the end of the first phase of a set of rigorous trials during which all of the ship’s systems and capabilities are evaluated to ensure they are in accordance with its plans and specifications.

During this phase of trials, Austal conducted comprehensive tests to the ship’s major systems including the combat, propulsion, ballasting, communications, navigations and mission systems.

“Millinocket performed well,” said Strategic and Theater Sealift Program Manager Capt. Henry Stevens. “Over the last few days, we conducted hundreds of tests to evaluate the ship’s systems, handling and capabilities all of which bring us one step closer to acceptance trials and delivery.”

Millinocket is the third ship of the JHSV class. This versatile transport ship will be used for the fast intra-theater transportation of troops, military vehicles and equipment.

JHSV is designed to commercial standards, with limited modifications for military use. The vessel is capable of transporting 600 short tons 1,200 nautical miles at an average speed of 35 knots, and can operate in shallow-draft ports and waterways, interfacing with roll-on/roll-off discharge facilities, and on/off-loading a combat-loaded Abrams Main Battle Tank (M1A2). Other joint requirements include an aviation flight deck to support day and night aircraft launch and recovery operations. The JHSV class will have airline style seating for 312 embarked forces, with fixed berthing for 104.

These are going to be very nice, high speed transports.

Austal US is really cranking up, and become a significant supplier to the US Navy. With the 12 Independence Class LCS she is building (two already in service and three more currently building) and with these 10 Spearhead Class JHSV vessels they are building (2 in service, 3rd completed sea trials, and two more building), Austal will have provided 22 vessels to the US Navy by the early 2020s...and will probably build more.

Certainly a few more (at least LCS) and perhaps more JHSV too.
