25 October 1944: During The Battle of Leyte Gulf, the Divine Wind Special Attack Unit (Shinpū Tokubetsu Kōgekitai, or 神風特別攻撃隊) carries out its first mission, an attack on two task groups of United States Navy escort aircraft carriers near the island of Samar in the Philippine Sea.

Prior to the Kamikaze attack of 25 October 1944, there had been other suicide attacks by Japanese pilots, possibly beginning as early as the attack at Pearl Harbor, Hawaii, 7 December 1941. But the idea of intentional suicide attacks was proposed by Captain Motoharu Okamura, IJN, and studies began 15 June 1944.

The first unit of 23 pilots, Unit Shikishima, was selected by Commander Asaichi Tamai. Lieutenant Yukio Seki (29 September 1921–25 October 1944) was appointed the unit’s commanding officer.

At 7:40 a.m., 25 October, six Japanese airplanes from Davao, Mindanao, attacked three Sangamon-class escort carriers of Task Group 77.4.1 (called “Taffy 1”), under the command of Rear Admiral Thomas Lamison (“Tommy”) Sprague, USN.

One airplane struck USS Santee (CVE-29) on the forward port side of the flight deck and continued through, blowing a 15 foot × 30 foot (4.6 × 9.1 meters) hole in the hangar deck. Fortunately eight 1,000 pound (454 kilogram) bombs located there did not explode. The resulting fire was extinguished by 7:51 a.m. In addition to the airplane’s pilot,16 sailors were killed and 27 wounded.

Five minutes later, at 7:57 a.m., Santee was hit on the starboard side by a torpedo launched by the Japanese Type B3 submarine, I-56.

Immediately after the crash aboard Santee, another Kamikaze circled USS Suwanee (CVE-27). It was hit by antiaircraft gunfire and headed toward USS Sangamon (CVE-26). A 5-inch shell fired by Suwanee brought it down short of Sangamon. At the same time, another Kamikaze nearly hit USS Petroff Bay (CVE-80), a Casablanca-class escort carrier, but was shot down by antiaircraft fire.

Suwanee shot down a second Zero and damaged a third. This airplane rolled over, and trailing smoke, hit the escort carrier’s flight deck forward of the aft elevator. Its bomb exploded between the flight and hangar decks.

Within two hours the flight deck damage had been repaired, though the elevator remained inoperative. Flight operations resumed at 10:09 a.m.

Five Mitsubishi A6M2 Type 0 Model 21 Reisen fighters (commonly referred to as the “Zero”, and also known by the Allied reporting name Zeke) led by Lieutenant Seki departed Malabacat, Luzon, and headed toward Task Force 77.4.3 (“Taffy 3”), under the command of Rear Admiral Clifton Albert Frederick (“Ziggy”) Sprague, USN. (Ziggy Sprague was not related to Tommy Sprague.)

Prior to this mission, Lieutenant Seki was interviewed by war correspondent Masashi Onoda. Seki is reported to have said, “Japan’s future is bleak if it is forced to kill one of its best pilots. I am not going on this mission for the Emperor or for the Empire. . . I am going because I was ordered to!”

Most of Taffy 3 had just survived an attack by the Imperial Japanese Navy’s overwhelming Center Force, consisting of the Japanese super battleship Yamato, battleships Nagato, Kongo, Haruna, cruisers Haguro, Chokai, Kumano, Suzuya, Chikuma, Tone, and two destroyer squadrons, in The Battle off Samar.

The Kamikazes approached the task group at very low altitude, avoiding radar, then climbed to 5,000–6,000 feet (1,524–1,829 meters). They appeared so suddenly that the fleet’s combat air patrol was unable to intercept. At 10:50 a.m., the first Zero attacked USS Kitkun Bay (CVE-71), apparently aiming for the carrier’s bridge. It missed, but passed over the island, crashed the port catwalk, and bounced into the sea. The bomb it carried exploded and seriously damaged the ship.

"A Japanese kamikaze pilot in a Mitsubishi A6M5 Model 52 ("Zero") crash dives on the U.S. Navy escort carrier USS White Plains (CVE-66) on 25 October 1944. The aircraft missed the flight deck and impacted the water just off the port quarter of the ship." (Naval History and Heritage Command 80-G-288882)

Two Zeros attacking USS Fanshaw Bay (CVE-70) were shot down. Two more dived on USS White Plains (CVE-66) but were driven off by the carrier’s 40 millimeter Bofors antiaircraft guns. One, smoking from a hit, turned away and dived toward the escort carrier USS St. Lo (CVE-63). At 10:51, St. Lo‘s guns opened fire, but this fighter, identified as a Mitsubishi A6M5 Type 0 Model 52 Reisen, crashed through the flight deck and exploded in flames.¹

In his classic 15-volume History of United States Naval Operations in World War II, Rear Admiral Samuel Eliot Morison, USNR, describes what followed:

Quickly there followed seven explosions of torpedoes and bombs on the hangar deck. Great sections of the flight deck and elevator and entire planes were hurled hundreds of feet into the air. The ship blazed from stem to stern, and at 1125 the unluckily renamed ² St. Lo foundered under a cloud of dense smoke.

The second member of this pair partly circled the formation, turned, and started a run on White Plains, which maneuvered to evade with hard left rudder. The plane came weaving under fire of all after guns; a torrent of blazing tracers could be seen entering its fuselage and wing roots. When only a few yards astern, it rolled over and dove, missing the port catwalk by inches and exploding between that level and the water. The flight deck was showered with debris and fragments of the pilot, and eleven men were injured.

RADM S. E. Morison, USNR, ca. 1953

As Kitkun Bay was steaming on course 200° at 1110, she sighted 15 Judys [Yokosuka D4Y Suisei dive bombers] approaching the formation from astern, distant about five miles. She launched two Wildcats by catapult for combat air patrol, but not in time. She and the three remaining carriers, Fanshaw Bay, White Plains and Kalinin Bay were without screen, owing to rescue work. One of the three Kamikazes got through the C.A.P. and dove at Kitkun Bay from astern. Its wings were shot off as it neared the ship, and just in time, for the bomb struck the water 25 yards on the starboard bow and parts of the plane hit the forecastle. Kalinin Bay received a crash dive on her flight deck which damaged it badly, but the fires then started were quenched in less than five minutes. A second plane crashed after her stack and two others dove but missed. Admiral Sprague’s flagship, the lucky “Fannie Bee,” alone alone sustained no damage in this assault.”

Of St. Lo‘s crew of 889 men, 113 were killed or missing, and another 30 later died of wounds.

Taffy 3’s remaining screening ships,³ the Fletcher-class destroyer USS Heerman (DD-531), with the Butler-class destroyer escorts USS John C. Butler (DE-339), USS Dennis (DE-405) and USS Raymond (DE-341), searched for survivors of the sunken St. Lo. They recovered 754 men.

Just after noon on 26 October, another group of Kamikazes attacked Taffy 1. The task group’s combat air patrol saved Santee from 12 Judys. Sangamon and Petroff Bay were narrowly missed.

At 12:40 p.m., a Zero crashed onto Suwanee‘s flight deck and hit a torpedo bomber which had just landed. Both airplanes exploded. Nine more of Suwannee‘s airplanes caught fire. 85 sailors were killed, 58 were missing and 102 wounded, some of whom later died of their injuries.

USS St. Lo (CVE-63) was a Casablanca-class escort aircraft carrier. Originally designated an auxiliary aircraft carrier, USS Chapin (ACV-63), the ship was laid down by the Kaiser Shipbuilding Co., Vancouver, Washington, 23 January 1943, under a Maritime Commission contract (M.C. Hull 1100). Chapin was renamed USS Midway (CVE-63) on 3 April 1943.

Midway was launched 17 August 1943, and commissioned 23 October 1943. Captain Francis Joseph McKenna, USN, was in command. The ship cost $6,033,429.05.

On 10 October 1944, Midway was renamed USS St. Lo (CVE-63), just 15 days before she was sunk.

St. Lo had an overall length 512 feet, 3 inches (156.14 meters), beam of 65 feet, 2 inches (19.86 meters) and maximum draft of 22 feet 4 inches (6.81 meters). The extreme width of the flight deck was 108 feet, 1 inch (32.95 meters). The ship had a full load displacement of 10,902 long tons (11,077 metric tons). It was powered by four Babcock & Wilcox boilers of 9,000 shaft horsepower (6,700 kilowatts), feeding two Skinner Unaflow vertical reciprocating steam engines, which turned two screws capable of driving it at 19 knots (22 statute miles per hour/35 kilometers per hour). The carrier had an unrefueled range of 10,240 nautical miles (11,784 statute miles/18,965 kilometers) at 15 knots (17 statute miles per hour/28 kilometers per hour).

"St. LO (CVE-63) slows to a stop as she is abandoned in an orderly manner. Note the men going down lines into the water." (National Archives and Records Administration 80-G-270511)
“St. LO (CVE-63) slows to a stop as she is abandoned in an orderly manner. Note the men going down lines into the water.” (National Archives and Records Administration 80-G-270511)

The flight deck was equipped with one steam catapult and two elevators.

St. Lo was armed by one 5-inch, 38-caliber (127 millimeter) dual purpose naval gun, sixteen 40 millimeter Bofors automatic antiaircraft guns, and twenty 20 millimeter Oerlikon autocannon. She carried 672 rounds of 5-inch, 3,298 rounds of 40 millimeter cannon shells, and 7,440 rounds of 20 millimeter shells. The carrier also carried 1,350 rounds of .45 ACP small arms ammunition.⁴

St. Lo carried 27 aircraft, including Grumman F4F or General Motors/Eastern Aircraft FM Wildcat fighters and Grumman TBF or General Motors TBM Avenger torpedo bombers.

The wreck of USS St. Lo is located near N. 11° 1′ 12″, E. 126° 2′ 24″.

¹ Historian John Toland named Lieutenant Seki as the pilot of this airplane, but Lieutenant Junior Grade Hiroshi Nishizawa, IJN, flying one of the A6M5 escorting fighters, reported that Seki’s airplane bounced off the deck of the carrier and its bomb did not explode. It crashed into the sea. He observed a second plane crash onto St. Lo, and its bomb did explode. Nishizawa was killed the following day, 26 October 1944.

² It is an old sailors’ superstition that it is unlucky to rename a ship. USS St. Lo had been laid down as USS Chapin Bay in January 1943. On 3 April 1943, it was renamed USS Midway. In order to free the name Midway for the new large aircraft carrier CVB-41, as well to commemorate the Battle of Saint-Lô, USS Midway was renamed USS St. Lo on 10 October 1944.

³ Along with USS Gambier Bay (CVE-73), Taffy 3’s escorting Fletcher-class destroyers, USS Hoel (DD-503) and USS Johnston (DD-557) and the Butler-class destroyer escort, USS Samuel B. Roberts (DE-413), were sunk several hours earlier by enemy naval gunfire during The Battle off Samar, when they heroically counterattacked the Center Force.

4 June 1942: At the Battle of Midway, beginning at 0702 hours, fifteen Douglas TBD-1 Devastator torpedo bombers were launched from the United States Navy aircraft carrier USS Hornet (CV-8) along with squadrons of Douglas SBD Dauntless dive bombers and Grumman F4F Wildcat fighters.

Lieutenant Commander John Charles Waldron, United States Navy. (U.S. Naval Institute)

Led by Lieutenant Commander John C. Waldron, Torpedo Squadron Eight (VT-8) flew at low altitude toward the expected position of the attacking Japanese fleet, while the fighters escorted the dive bombers at high altitude. Waldron sighted the enemy fleet at a distance of 30 miles and ordered his squadron to attack. Without any fighter escort, the slow flying torpedo bombers were attacked by Japanese Navy A6M2 Type 0 fighters and defensive anti-aircraft fire from the warships. All fifteen TBDs were shot down.

A detachment of VT-8, flying Grumman TBF-1 Avengers, had been sent ahead to Midway from Pearl Harbor. These six torpedo bombers, led by Lieutenant Langdon K. Fieberling, also attacked the Japanese fleet. Five were shot down by intercepting Zero fighters. The sixth, flown by Ensign Albert Kyle Earnest, was badly damaged and its gunner killed. The torpedo bomber was able to return to Midway but crash-landed. It was the only aircraft of Torpedo Eight to survive the Battle of Midway.¹

Only one man, Ensign George H. Gay, of the thirty pilots and gunners of Torpedo Eight who had launched from USS Hornet, survived. Ensign Earnest and Radioman Harry Hackett Ferrier, were the only survivors of the 18 men from the Midway detachment of VT-8. The torpedo bombers failed to score any hits on the Japanese ships, and their machine guns did not bring down any of the Zeros.

In the enigmatic ways of warfare, the attack by Torpedo Eight caused all of the Japanese fighters defending their aircraft carriers to descend to low altitude in their efforts to shoot down the American torpedo bombers. When the SBD Dauntless dive bombers from USS Enterprise and USS Yorktown arrived a few minutes later, there were no Japanese fighters at high altitude to interfere with their attack.

The dive bomber attack was devastating. The aircraft carriers Akagi, Kaga and Hiryu were bombed and sunk. Soryu received major damage, and was sunk by its escorting destroyers later in the day.

The Imperial Japanese Navy, up to this time on the offense all over the Pacific and Indian Oceans, never recovered from the loss of the experienced pilots that died when those carriers went down.

In his After Action Report, Hornet‘s commanding officer, Captain Marc A. Mitscher (later, Admiral) wrote:

Beset on all sides by the deadly Zero fighters, which were doggedly attacking them in force, and faced with a seemingly impenetrable screen of cruisers and destroyers, the squadron drove in valiantly at short range. Plane after plane was shot down by fighters, anti-aircraft bursts were searing faces and tearing out chunks of fuselage, and still the squadron bored in. Those who were left dropped their torpedoes at short range.

No. 00380 was returned to Pearl Harbor for inspection. It had been hit by at least nine 20 mm cannon shells and sixty-four 7.7 mm machine gun bullets.

4 June 1942: The Battle of Midway: The Japanese naval task force (First Mobile Force) under Vice Admiral Chuichi Nagumo, consisting of the aircraft carriers IJN Akagi, IJN Kaga, IJN Hiryu and IJN Soryu, along with their escorts of battleships, cruisers, destroyers and supporting tankers, launched the first attack at 0430 against the United States base at Midway Island. The attackers consisted of 36 Aichi D3A dive bombers, 36 Nakajima B5N torpedo bombers and 36 Mitsubishi A6M Zero fighters as escort.

The incoming aircraft were detected by radar on the island and defending U.S. Marines fighters—obsolescent Grumman F4F Wildcats and obsolete Brewster F2A Buffalos—were launched to defend the island’s airstrip and facilities. 15 U.S. Army Air Force B-17E Flying Fortress heavy bombers and 4 Martin B-26 Marauder medium bombers took off to attack the Japanese carriers.

The Marine fighters were outnumbered and technologically inferior. 4 of the F4Fs and all 12 F2As were shot down. The Japanese lost 4 torpedo bombers and 3 Zero fighters. Facilities on the island were heavily damaged by the dive bomber attack, but it was not put out of action.

1 April 1939

The first prototype Mitsubishi A6M1 Type 0, c/n 201. (Mitsubishi Kokuki K.K.)

1 April 1939: Mitsubishi Kokuki K.K. (Mitsubishi Aircraft Company) Chief Test Pilot Katsuzo Shima made the first flight of the prototype Mitsubishi A6M1 Navy Type 0¹ fighter at the Kagamigahara air field (now, Gifu Airbase).

Completed about ten days earlier, at the Mitsubishi Aircraft Company factory at Nagoya on the island of Honshu, the prototype fighter had been disassembled so that it could be transported by road approximately 22 miles (36 kilometers) to the airfield.

Beginning late in the afternoon with taxi tests and a brief “hop” to check control response, at 5:30 p.m., Shima took off on what would be a successful test flight.

The prototype S12, serial number 201, had been designed in response to an Imperial Japanese Navy requirement for a new, light-weight fighter for operation from aircraft carriers. The design team was led by Dr. Jiro Horikoshi, an engineering graduate from the Aviation Laboratory at the University of Tokyo.

The Type 0 (best known as the “Zero”) was a single-place, single-engine, low-wing monoplane with retractable landing gear. It was of very light construction, being primarily built of a special aluminum alloy, although its control surfaces were fabric covered. The empty weight of the first prototype was just 1,565.9 kilograms (3,452.2 pounds). Its test weight on 1 April was 1,928 kilograms (4,251 pounds).

The two prototype A6M1s were powered by an air-cooled, supercharged, 28.017 liter (1,709.7 cubic inch displacement) Mitsubishi MK2C Zuisen 13, a two-row, fourteen cylinder radial engine, rated at 780 horsepower for takeoff. The engine initially drove a two-bladed variable pitch propeller, but during testing this was replaced by a three-bladed Sumitomo constant-speed propeller, which was manufactured under license from Hamilton Standard.

The combination of very light weight and relatively low power made the Zero very maneuverable and capable of long distance flights.

After the success of the A6M1’s initial flight tests, a second prototype, c/n 202, was built and testing continued. In September 1939 the Japanese Navy accepted the new fighter, the Rei Shiki Sento Ki, or “Rei-Sen,” and it was ordered into production with few changes.

The first production model was the A6M2 Type 0 Model 21. The Mitsubishi engine was replaced by a more powerful Nakajima NK1C Sakae 12. The fighter’s wing tips could be folded upward for a slight improvement in storage aboard aircraft carriers.

Sources vary on the exact dimensions of the Zero fighters. The National Naval Aviation Museum at NAS Pensacola, Florida, which has an A6M2 in its collection, gives the airplane’s length as 29 feet, 8.6 inches (9.058 meters). The wingspan is 39 feet, 4.5 inches (12.002 meters), and the height is 10 feet, 0 inches (3.048 meters). It has an empty weight of 1,680 kilograms (3,704 pounds), and loaded weight of 2,796 kilograms (6,164 pounds), about half the weight of its rivals, the Chance Vought F4U Corsair and Grumman F6F Hellcat.

The A6M2 Type 0 was powered by an air-cooled, supercharged, 27.874 liter (1,700.962 cubic inch) Nakajima Hikoki K.K. NK1C Sakae 12, a two-row, fourteen-cylinder radial engine which was rated at 925 horsepower, and drove a three-bladed Sumitomo constant-speed propeller through a 1.71:1 gear reduction.

The Model 21 had a cruise speed of 207 miles per hour (333 kilometers per hour). Its maximum speed was 277 miles per hour (446 kilometers per hour) at Sea Level and 335 miles per hour (539 kilometers per hour) at 16,000 feet (4,877 meters). The service ceiling was 37,000 feet (11,278 meters) and maximum range, 1,175 miles (1,891 kilometers).

The A6M2’s armament was manufactured by Dai Nihon Heiki K.K. Two Type 97 7.7 mm (.303-caliber) machine guns were mounted on the forward upper fuselage, synchronized and firing through the propeller arc. These were licensed versions of the Vickers Type E .303 machine gun. There were 600 rounds of ammunition per gun. A Type 99 20 mm autocannon was mounted in each wing with 100 shells per gun. The Type 99 was a licensed version of the Oerlikon FF autocannon.

The Mitsubishi A6M Zero was one of the most successful fighters of World War II. Although its light construction made it vulnerable to the heavy machine guns of American fighters, in skilled hands, the highly maneuverable Zero was a deadly opponent.

The Mitsubishi A6M Type 0 was produced from 1940 through 1945. 10,939 Zeros were built. At the end of World War II, almost all of the surviving fighters were destroyed and only a very few remain.

An A6M2 was captured near Dutch Harbor in the Aleutian Islands in June 1943. Known as the “Akutan Zero,” the fighter was extensively tested by the U.S. Navy and the National Advisory Committee for Aeronautics (NACA) at NAS Anacostia. Under extreme secrecy, the airplane was also tested in the Full Scale Wind Tunnel at NACA’s Langley Memorial Aeronautical Laboratory at Hampton, Virginia.

¹ The 0 (the numeral zero) in the fighter’s type designation refers to the the final digit of the year 2600 of the Imperial Japanese Calendar, which was 1940 AD by the Gregorian calendar. This gave the A6M2 its most common identification, simply, “the Zero.”

3 March 1942: A Koninklijke Nederlandsch-Indische Luchtvaart Maatschappij (KNILM) Douglas DC-3 airliner, registration PK-AFV, named Pelikaan, was flying from Bandoeng, Java, Dutch East Indies, to Broome, Western Australia. The flight was under the command of Captain Ivan Vasilyevich Smirnov, a World War I fighter ace of the Imperial Russian Air Service. There were three other crew members and eight passengers on board.

At about 10:30 a.m., as the DC-3 approached the shore of Western Australia, it was attacked by three Mitsubishi A6M2 Navy Type 0 Model 21 (“Zero”) fighters of the Third Kokutai, Imperial Japanese Navy, then based at Timor. The flight was lead by Lieutenant Zenjiro Miyano, IJN.

Captain Smirnov and several others were wounded and the airliner’s left engine caught fire. Smirnov made a crash landing on a beach at Carnot Bay, approximately 50 miles (80 kilometers) north of Broome. The fighters continued to strafe the DC-3 on the beach.

The following day, 4 March, the airliner was bombed by a Kawanishi H6K “Mavis” four-engine flying boat, but there was no further injury or damage.

Over the next several days, four of the passengers died of wounds. The survivors were rescued on 9 March.

The diamonds disappeared.

A beach comber, John (“Diamond Jack”) Palmer, later turned in a parcel of diamonds which he said he had found on the beach. These were valued at A£20,447, but were only about 10% of the original amount. Palmer was charged with stealing the diamonds, and he and two others, John Arthur Mulgrue and Frank Archibald Robinson, were charged with unlawfully receiving the diamonds. They were prosecuted in 1943, but all were acquitted.

[Douglas C-47 Skytrains were equipped with the R-1830-92 (Pratt & Whitney Twin Wasp S1C3-G). These had a maximum continuous rating for normal operation was 1,060 horsepower at 2,550 r.pm., up to 7,500 feet (2,286 meters), and 1,200 horsepower at 2,700 r.p.m., at Sea Level, for takeoff. Each engine drives a three-bladed Hamilton Standard Hydromatic constant-speed full-feathering propeller with a diameter of 11 feet, 6 inches (3.505 meters) through a 16:9 gear reduction.
