The last air combats over the Philippines
The next stage of the Japanese attacks by suicide aircraft commenced in late November 1944 when the units in the Philippines were reinforced with 450 aircraft from Taiwan. These were used immediately to form new Kamikaze units. One of these, the 3rd Shimpū Tokubetsu Kogekitai, assembled at Nichols Field and Mabalacat. The unit was equipped with Mitsubishi A6M ‘Zero’ fighters, Kugisho D4Y Suisei ‘Judy’ dive-bombers and twin-engined Kugisho P1Y Ginga ‘Frances’ land-based bombers. It began operations on 25 November 1944. The first to go into action was the Yoshino tai unit, under Sub-Lieutenant Masami Takatake. Six ‘Zero’ fighters and two ‘Frances’ bombers arrived over the American fleet commanded by Admiral Gerald F. Bogan at 1130, and two more attack groups followed.
The first group was met with heavy AA fire from the carrier USS Cabot, but two Kamikazes hit the ship. Only slight damage resulted, but 15 American sailors were killed and 16 were wounded. Two more Japanese aircraft hit the carrier USS Intrepid: the first struck a gun position and destroyed it, before falling onto the deck and causing a fire to start. The other Kamikaze exploded on the deck, from which 75 aircraft had just taken off. Damage to the deck was substantial meaning aircraft from the USS Intrepid had to find alternative places to land. The carrier lost 79 sailors killed and 43 wounded. The third target of the attack was the carrier USS Hancock, which came under attack by four ‘Zero’ fighters. Two of these were shot down by AA fire and the third burst into flames after American fighters intervened. When the fourth flew into the dense AA fire, its wings were shot off and most of the remaining wreckage missed the carrier but hit the destroyer next to her. The destroyer sustained slight damage. A few fragments of wing and fuselage fell onto the carrier, causing no damage.
The last to be attacked was the flag carrier, USS Essex. One of the attacking aircraft was shot down, but another crashed into the flight deck and 15 sailors were killed. A total of eighteen Kamikaze aircraft were shot down. The attacks continued into the next day and respite only came

Kamikaze effectivenessThe effect of suicide attacks is quantified by the numbers below. However, this can never be
a complete reflection, as in addition to the officially recorded attacks by Kamikaze units, many suicide attacks were not recorded as they were performed by individual pilots or by small groups on their own initiative.

The Navy trained a total of 1,727 pilots, whose age varied between 18 and 20 (there were in fact several pilots aged 17). Of these, 110 pilots were students of the military academy. One Vice-Admiral and two Captains were killed, and the others were ranks between Warrant Officer and Lieutenant. Most of them had graduated from the military academy in 1943.
In the Army, most pilots had graduated from advanced flying schools. Most pilots were Sub-Lieutenants, and their average age was 25. Warrant Officers were generally aged 18 or 19.
The world learned more about the origin and operations of the Kamikaze units through the trials of Japanese commanders held after WWII. The principal trial was held in Tokyo by the International Far East Court between 3 May 1946 and November 1948, during which 28 Japanese commanders were tried for war crimes. The bill of indictment included 55 charges, mostly crimes against world peace, the conventions of war, and against humanity.
The 48th charge included the use of suicide units. It was agreed that this was not only a case of a crime against humanity, but also a crime against their own nation. However, on 25 October 1974, on the 30th anniversary of the establishment of the first Kamikaze unit at the Philippine base at Mabalacat, a monument with a memorial plaque was unveiled. Later, subsequent monuments were built, wherever Kamikaze units were based. A monument to Yukio Seki, the first of many subsequent pilots who gave their lives for Japan and the Emperor, was also erected.
There are more and more documents published about the actions of the special units, mostly memoirs of those who did not see their turn come. The Japanese have not forgotten their sons, sent to certain death in defence of their home.

No production Ki-115 Ko aircraft reached combat units. Even so, plans for a further-developed version designated Ki-115 Otsu were underway. The Otsu variant had a new wing which had increased span and area. The plan was to fit it with normal flaps, and the cockpit was relocated slightly forward to improve visibility. It was going to be built entirely of wood, to minimise the use of duralumin. However, although design work had been completed, no prototype of the Ki-115 Otsu was built as the project was overtaken by the end of the war.
The Ki-115 Hei variant also remained on paper. This featured significantly improved visibility as a result of locating the cockpit even further forward than on the Otsu. It was also going to be fitted with a manual bomb release so the pilot could jettison the bomb, or use the aircraft like a conventional bomber - previous versions of the Tsurugi had no option to release the bomb from the cockpit, which would have made landing in the event of an aborted mission impossible.
Two production Ki-115 Ko aircraft were completed and tested with two solid fuel rocket boosters under the wings. The rockets were intended to accelerate take-off of the aeroplane from hastily prepared air strips, or to increase diving speed in the final phase of the suicide attack.
The Navy was also interested in the Ki-115 Tsurugi. The Kaigun Koku Hombu issued Nakajima its own specification for a similar aeroplane type and placed an order, giving the machine the designation of “Experimental Navy special aeroplane Toka” (Wisteria Blossom). Changes included, among others, an increased wing area of 13.10m2, and a number of minor modifications in the equipment (mainly the re-scaling of instruments to knots rather than km/h). According to Nakajima’s calculations, the introduction of the changes requested by the Kaigun Koku Hombu would reduce
