I-400

As commissioned on December 30th, 1944

Created for a covert strike against the critical Panama Canal, the I-400s could carry three Aichi M6A Seiran floatplanes to anywhere in the world, without refueling. They remain the largest diesel submarines ever constructed.

Details of I-400's early service are sparse, She participated in pilot training along with I-401, I-13, and I-14 between June 5th and 20th 1945, with pilots training for the attack on the Panama Canal.

When Okinawa fell, the plan of attack was changed, with the target now being Ulithi Atoll, where fifteen US carriers had assembled to stage raids on the Japanese Home Islands.

As captured on August 29th, 1945

I-400 was captured by USS Blue, astonishing the destroyer's crew with her sheer size, being considerably larger than any of the American fleet boats. Her crew had ditched all the aircraft and torpedoes 7 days prior to her capture. At some point during her time as a prize boat, her nameplate was repainted with US style markings.

She was expended as a target on June 4th, 1946, sinking off the coast of Oahu.

I-401

As commissioned on January 8th, 1945

I-401, shown with one of her aircraft painted in fake US scheme, was commissioned too late in the war to accomplish her objectives, though made several attempts to launch. She had sailed for her first target by the time Emperor Hirohito's ceasefire broadcast was received on the 15th of August, 1945. She would hoist a black flag of surrender on the 26th, and all of her aircraft, weapons, codebooks, charts, and logs were destroyed. She would be captured by USS Segundo on the 29th.

She was expended as a target on May 31st, 1946, sinking off the coast of Kalaeloa, Hawai'i.

I-402

As commissioned on July 24th, 1945

I-402 was converted to a tanker submarine prior to commissioning and was never loaded with aircraft, she would see no action in the war.

She would be scuttled as a part of Operation Road's End on April 1st, 1946.

Very nice work! These were drawn previously, but only I-400 was represented. Excellent work in showing all three members of the class. Incidentally, all three wrecks have now been located.

looks really good. My only irk is that (this applies to other's as well), try to use always darker shade than the background structure when painting railing, not lighter, since it doesent really remain consistent with the rest of the style's logic

I am aware that the STO had already been drawn, but the previous drawing was quite badly in need of a redo.

Understood. Are you planning any other IJN-related drawings?

No, it's back to Nyrdanmark after this.

I apologize if you meant to redraw them yourself or took offense at my statement of the drawings being wrong, I meant no offense.

Very good work, though I'm used to seeing them in a much brighter paint scheme!

Bronies are like the Forsworn. Everyone agrees that they are a problem but nobody wants to expend the energy rooting them out.
