Aviation operation for T.H. using two sets of flying boats (two sets size boat) which the Japanese Navy carried out during World War II with the Operation K (けーさくせん) of the United States. The first planned an air raid for Pearl Harbor. These two sets of strategies became the first actual fighting of the size boat. The second planned the reconnaissance for the enemy task force considered to be in Hawaii for Operation Midway.

The first
Plan
The Japanese Navy performed the reconnaissance of the spy plane which took off from submarine Italy 7 on December 17, 1941 after the Pearl Harbor attack in Hawaii and performed the reconnaissance with the deployment machine from Italy 19 on January 5, 1942, the following day. I in this way knew that I did restoration of the damage of the Pearl Harbor attack at a fast pace without U.S. forces doing the blackout.
As a result, a plan attacking further Pearl Harbor with the two sets size boat happens because I continue losing in those days in each place and appeared at the same time to interfere with restoration activity, and even the mainland adds the further damage to the morale of the attacked United States Armed Forces. On January 17, the combined fleet chief of staff conveyed it to perform the study and plan drafting in the South Seas corps Airlines corps headquarters.
The participation military power left the Marshall Islands ウオッゼ island with two planes and was a plan to receive refueling from a submarine on the way in French frigate 礁.
I it in progress
The two sets size boat left Yokosuka on February 12, 1942 and arrived at Marshall Islands Jaluit Atoll on 14th. In addition, I remodeled Italy 15, Italy 19, 水偵格納筒 of Italy 26 by the middle of February and completed an aviation fuel supply device.
On February 20, the U.S. task force appears in the Rabaul east. Furthermore, the strategy was postponed on 2nd because Wake Island caught the air raid on 24th, and the submarine which participated in a strategy engaged in a searching for the enemy.
On March 2, the two sets size boat moved to the ウオッゼ Island. The submarine which filled up with gas it went into French frigate 礁 by the early morning of 3rd.
(in Japan time, I agree as follows), two sets size boat two (Second Lieutenant Captain first plane, Toshio Hashizume machine, second machine, bamboo-grass-grown place Shosuke machine) left the ウオッゼ island at 0:25 on 4th. I received an instruction by the long wave irradiation from Italy 9 on the way and arrived at French frigate 礁上空 at 13:00. I landed on the water at 13:50 and detached room water did refueling from Italy 15, Italy 19 at start, 16:00 and went to Hawaii.
Both planes passed with Necker Island (16:57), ニイハウ island (18:25), Kauai Island (19:35) and arrived at the Oahu offing at approximately 21:00. I caught two planes by a radar of Kauai Island at 18:44 and recognized the American side the other day when it was a friend airplane at first, but I let Catalina flying boat and P-40 fighter take off as an interceptor for a precaution and announced an air-raid alarm at 19:18. But, at 21:30, four 250 kilos bombed each, and, at the opportunity, the second machine left for home most at 21:10 without being discovered in these interceptors.
The plane returns to Jaluit Atoll most at 9:20 on 5th. Because the second machine had a damage in detached room water after the refueling, toward the ウオッゼ island, I arrived at 9:10 on 5th.
The strategy was accomplished on schedule, but the badness of the view of the sky in a hurry of the の blackout was saving it, and came off the bomb in the aims such as a dock and a fuel tank in Pearl Harbor, the anchoring ship, and dropped on neighboring roads, and the damage on the United States side was minimal.
In addition, two two sets size boats were spent afterwards by Midway Island and the reconnaissance for the Johnston island. I left ウオッゼ on March 10, but the plane (Hashizume machine) toward the Midway Island is caught by a radar, and I am shot down by F4F fighter.
The second
Plan
The Japanese military which decided the capture of the Midway Island decided to perform the enemy's condition reconnaissance of the Hawaiian area with the two sets size boat. This strategy was named Operation the second K and was a plan to carry out the refueling from a submarine in French frigate 礁 like the last time.
Status confirmation of Pearl Harbor is important to the combined fleet and, for Midway strategy planned assuming what the U.S. task force does in Pearl Harbor in a living-in-night in May, 1942, plans the second K strategy spying upon submarine patrol deployment and the enemy's condition by two sets of flying boats as intellect enemy means.
I spied upon Pearl Harbor by two sets size boat by June 3 and, in the plan, was a plan to put a patrol network for the U.S. fleet toward Midway on from Pearl Harbor by June 2. When a Midway capture corps to leave Saipan on May 28 even if I advanced as scheduled was discovered, and the U.S. task force of Pearl Harbor moved because this submarine and patrol network with the flying boat were plans of June 2, it was a strategy not to be in time for [1].
I it in progress
Because there was not the staff officer of the submarine native place in the combined fleet, the strategy lets 水雷参謀有馬高泰 hold an additional post, and, as for the Lieutenant Colonel Arima, six third diving squadrons, the fifth diving squadron eight make the strategy point to form, and to watch a patrol network to Namboku Line by June 2 on the Oahu 900, Nishikata kilometer sea surface on May 18 without the sixth fleet headquarters inviting it. However, I could prepare only 11 submarines, and it was one ship to be able to arrive on June 2, and, as for staying, it was arrival on after 3rd, but just consented tacitly without the combined fleet changing a strategy [2].
The U.S. forces were cautious of similar strategy with the flying boat being repeated after Operation the first K. U.S. Navy discovered that French frigate 礁 was used as a way station on May 6 by communication analysis and decryption of the radio communication by the Japanese Navy [3]. In U.S. Navy, it was decided that I dispatched a war vessel and guarded it to prevent the use of French frigate 礁.
On May 30, Italy 123 in charge of the refueling arrived at French frigate 礁 for Operation the second K. However, minelayer "pre-bulldog" (en, former Klem loss grade destroyer) and aircraft carrier "Sohnton" (USS Thornton (DD-270), former Klem loss grade destroyer) of U.S. Navy unfolded earlier and were guarding it. Italy 123 notices the existence of the United States ship and postpones a strategy. Similarly Italy 121 in charge of the refueling arrives at French frigate 礁 and, on 31st, the following day, watches the trend of the United States ship with Italy 123. The caution of the United States ship was severe on that day, and the strategy was called off on June 1, the following day.
The Japanese military would fight by the Battle of Midway without being able to confirm the enemy's condition of the Hawaiian area, and, by failure of the Operation the second K, it was one of the cause of defeat on the Japan side.
The combined fleet which received a report of the failure did not take measures against a plan having collapsed at all. Combined fleet staff officer Kameto Kurojima tells, "I do Toshin judging from naval common sense after the deployment line constitution of this case is western, and 概成 did an open order and should touch a submarine for the appointed deployment and, however, have planned such deployment with from the mistakes of my enemy's condition judgment, and, besides, the preparations for submarine have been late without the instruction of the combined fleet reaching it, and the diving corps should have concentrated all military power of the combined fleet again in this time because a strategy is a strategy to perform using the main military power of the combined fleet" after the war [4]. Japan completely lost the intellect enemy means of the enemy task force by Operation K failure, but Kuroshima "did not think about the measures that, therefore, were special because our task force was unrivaled and believed it when I could overwhelm an enemy" [5].
