Imgur ate the remainder of my put up and ate the part about ZackWester after I updated it.
I had a complete put up with varied photos and a abstract of

Here is the description I summarized from that article:
Admiral Yamamoto came up with the theory and Captain Kameto Kuroshima used to be tasked with a feasibility see, executed it in 1942, “and the Japanese Rapid Headquarters approved it at the moment later on. His proposal used to be to present 18 of these ships with the aptitude of making three round trips to the west fly of the US with out the necessity to refuel, or one round outing to any place on the earth. No longer handiest that, the vessels valuable with a purpose to preserve up now not less than two assault planes armed with either torpedoes or bombs. Total plans had been executed the identical year.”
When Yamamoto used to be killed the notion used to be reduced to 5, nevertheless handiest 3 had been executed, and handiest 2 entered provider.
“Each of these spectacular machines used to be powered by four 1,680 kW engines. They even had enough gas to commute round the enviornment one and a half of times. They measured 120 meters in dimension and displaced round 5,900 loads, which used to be extra than double that of their American counterparts. Their inappropriate part used to be a special resolve of eight configuration, owing to the waste plane hangar. This supplied the vital strength and steadiness to manage to pay for the ship of facing the additional weight of the hangar and now not fabricate them top heavy. The plane hangar used to be appropriate under the conning tower and mounted alongside the ship’s centerline.
“This plane hangar used to be, clearly, water tight and cylindrical in fabricate. Its outer obtain entry to door used to be opened hydraulically internally or manually from the exterior. It had a 51 mm thick rubber gasket.
“No longer handiest did the ship contain aerial strike capabilities nevertheless used to be also geared up with one of the precious ideally capable guns ever seen on a submarine. She used to be geared up with three waterproofed Form 96 triple mount 25mm anti-plane protection guns and a single Form 11 140mm deck gun aft of the hangar!
“The vessel, being a submarine, used to be also geared up with 8 torpedo tubes mounted on the bow with out a aft tubes.”
“No longer handiest would possibly additionally the [Seiran fighters’] wings be folded support nevertheless also the waste segment of the vertical tail stabilizer and complete horizontal stabilizers. The namely designed fighter’s pontoons had been also removable and saved in separate compartments on either aspect of the hangar.”
“Warring parties had been launched from a 26-meter forward deck mounted compressed air catapult on the bow of the ship. The warring parties had been recovered utilizing a storable collapsible crane. Below the observe, four high-stress air flasks had been linked in parallel to present enough `thrust’ to begin the warring parties to takeoff drag.
“All by fighter deployment, snappily start of warring parties used to be a necessity. As older WW2 warring parties in general required a whereas to warm up, namely designed oil pre-heaters had been employed to acquire the engines up to operational temperature as snappily as that you just would possibly possibly think. This used to be also valuable as you would possibly possibly now not contain engines ticking over when submerged, you would possibly possibly additionally appropriate waste the crew!”
All three boats had been “captured by the U.S. Navy they most continuously either sunk I-400 and I-401 as target observe in 1946 or converted to tanker submarine, I-402. I-402 used to be later sunk in 1946 of the Goto Islands by the U.S. Navy.”
