Interesting concept, a submarine that can fly....

Actually subs acts like aeroplanes when submerged.
Water and air is the medium that they "fly" in.

....and there's nothing quite like being in a hunter killer when it does a "significant evasive manouver"

....and there's nothing quite like being in a hunter killer when it does a "significant evasive manouver"

I remember an incident from my tour on USS Buffalo, a Los Angeles-class Fast Attack. We were comducting training and certification operations for Prospective Commanding Officers (PCO) of submarines, in the Submarine Operations Areas off Maui, Hawai'i.

One PCO, who had only served on older Fast Attacks and Lafayette-class missile boats, had the Conn, with a Buffalo-Qualified Officer of the Deck (OOD), and the PCO Instructor, a full-bird Captain, observing. Submerged at depth, running Ahead Full, the PCO ordered Right Full Rudder. The Helmsman questioned it, the PCO repeated the Order. The OOD asked the PCO if he was sure he wanted to do that, and looked questioningly at the PCO Instructor. The PCO repeated his order. Getting no signal from the PCO Instructor, but knowing exactly what was going to happen, the OOD ordered "Right Full Rudder". The helmsman repeated back, and executed the maneuver, then centered the helm.

Can you say "Snap Roll" to the right? Even properly stowed for sea, there was a lot of noise from the galley and other places, as things flew out of their stowage lockers. At the time, I was strapped into my chair (as required) at the Electric Plant Control Panel back in the Engineroom.

About the time we got back to proper depth and course, the Commanding Officer came out of his Stateroom and asked "Who's the jackass who just trashed my stateroom?" The PCO rather sheepishly admitted it was him. The CO told him that when he came off watch, to come clean up his mess. The Instructor was just barely suppressing a huge grin. Lot of learning took place that day....

I always wondered about the glass windows on the front. Some how that seems like such a bad idea.

The big, flat, windows might be OK for shallow dives, but for deep dives would become a structural liability.
Interesting concept, a submarine that can fly....

We had lead-glass windows for viewing the shielded volume of the Reactor Compartment. 2-foot thick, and certified to hold against full reactor plant pressure in the event of a piping rupture.

Deep-diving submersibles have large windows, but they do follow the curve of the pressure hull, as the Seaview's windows seem to. The Seaview also had doors that closed over the front of the windows to protect against collisions.

Good point about the windows. I found a sub for sale, it also has a big front window. Anyone want a sub. Only $260K

We go submarines in the Stockholm archipelago.
The only commersial mini-sub in northern Europe.
http://www.livetombord.se/filmer/20141020/vi-aker-ubat-i-stockholms-skargard/

Expect more submarines in the Stockholm archipelago to come. It is in any case restaurateur E-types hope when he soon open the doors to its new "U-boat bar" at Dalarö Skans.

Concept Bars in Stockholm has become more and more. The Ice Bar at the Nordic Light Hotel, Hospital Clinic at the bar Zinkensdamm and the new raw bar in Bruno mall are just a few examples.

Next up is the artist and restaurateur Martin "E-Type" Eriksson, who recently purchased the tavern Dalarö Skans in the Stockholm archipelago, at the fortress of the same name that dates back to the early 1600s.

The fortress, which for centuries was an important defense position for the inlet south of Stockholm, has in recent years hosted a private event and wedding business. And it is precisely the theme of the defense makes a comeback when Martin Eriksson will take over and open its doors in the next year. One of the innovations on the island is namely a "U-boat bar".

- There's a little sad wooden bar on one side of the island. Now we are building a U-boat bar with a U-boat harbor. U-boats from all countries are welcome, says Martin Eriksson.

How's this for a window view. Dive certified to 3000 feet.

A submarine I have just got intrested in is the Japanese Sen-Toku class. The sub that could carry 3 airplanes. The US had posesstion of 2 of them after the war and studies then. The sank them to keep the Russians from studying them.

I guess Im going to have to do some research and find out what the US didnt what the Russians to find out.

A Submarine aircraft carrier, that's possibly all the US wanted to keep out of Russian hands, unless it was connected with the flea attack by balloon the Japanese did in WWII that were laced with Bubonic Plague, which did reach the US and was kept secret for decades.

Sounds like the I-400 class. Largest submarines in the Pacific, as I recall. Don't remember if they were larger than the German "milch cow" tanker subs that refueled the regular U-boats.

There are some very good books on WWII submarine warfare available from the US Naval Institute Press (USNI.org).

They were larger than the German tanker subs: "The I-400-class submarine (伊四百型潜水艦 I-yon-hyaku-gata sensuikan?) Imperial Japanese Navy submarines were the largest submarines of World War II and remained the largest ever built until the construction of nuclear ballistic missile submarines in the 1960s" https://en.wikipedia.org/wiki/I-400-class_submarine

I've no idea which is larger either, but if an I-400 can launch a float plane, then a cruise missile with folding wings and possibly jet engines and not pulse jets could have been launched from an I-400, the V1 had a proposed version with one jet engine instead of the pulse-jet, at least that's what I've read, WWII trivia, I was trying to get an idea of what My Dad did in WWII Europe, I later found out what He did after His death(He thought I wouldn't approve, rubbish, He saved lives, I couldn't approve more), a medic in the 368th Medical, I think I know why He didn't trust Doctors too much now, at least partly, something He saw.

What little I do know is the I-400 class held 3 float planes. Im sure there must have been other reasons why the US didnt want the Soviets to get there hands on one. Possible dive depth, Crusing range both above and below water, I guess I need to buy the book on the I-400 class.

And maybe Vic you have suggested something else. What if instead of planes we stick missles in the hangar. Im sure there was someting about how the hangar was made to keep water out that was top secret at the time.

Do a google search "i400 submarine" and you find a lot.

They were submarine aircraft carriers able to carry three Aichi M6A Seiran aircraft underwater to their destinations.

We did, in fact use a variation on the I-400 external hangers for the 3 diesel subs that carried Regulus cruise missiles in the late 1950s. The lone nuke boat, USS Halibut (SSN-587), was modified during construction to extend her forward torpedo room to allow internal storage of the missiles. All 4 had to surface to launch, and were made obsolete when the USS George Washington class SSBNs and the Polaris ballistic missile entered the fleet.

These subs were part of a plan to bomb the western locks of the Panama Canal during WWII.

Thank you Donald. Ever since I had heard of the I-400 class, I wonderd why we just scuttled them. That would explain a lot.
Just goes to show a military secret is sercret very long though.
