Countdown to Kickoff II: The Final 24 Days

Mitsubishi A6M Zero

The Mitsubishi A6M "Zero" was a long-range carrier-based fighter aircraft formerly manufactured by Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945. The A6M was designated as the Mitsubishi Navy Type 0 carrier fighter (零式艦上戦闘機, rei-shiki-kanjō-sentōki), or the Mitsubishi A6M Rei-sen. The A6M was usually referred to by its pilots as the Reisen (零戦, zero fighter), "0" being the last digit of the imperial year 2600 (1940) when it entered service with the Imperial Navy. The official Allied reporting name was "Zeke", although the name "Zero" (from Type 0) was used colloquially by the Allies as well.

The Zero is considered to have been the most capable carrier-based fighter in the world when it was introduced early in World War II, combining excellent maneuverability and very long range. The Imperial Japanese Navy Air Service (IJNAS) also frequently used it as a land-based fighter.

In early combat operations, the Zero gained a reputation as a dogfighter, achieving an outstanding kill ratio of 12 to 1, but by mid-1942 a combination of new tactics and the introduction of better equipment enabled Allied pilots to engage the Zero on generally equal terms. 

By 1943, the Zero was less effective against newer Allied fighters due to design limitations. It lacked hydraulic boosting for its ailerons and rudder, rendering it extremely difficult to maneuver at high speeds. By 1944, with Allied fighters approaching the A6M levels of maneuverability and consistently exceeding its firepower, armor, and speed, the A6M had largely become outdated as a fighter aircraft. However, as design delays and production difficulties hampered the introduction of newer Japanese aircraft models, the Zero continued to serve in a front-line role until the end of the war in the Pacific. During the final phases, it was also adapted for use in kamikaze operations. Japan produced more Zeros than any other model of combat aircraft during the war.

Name

The A6M is usually known as the "Zero" from its Japanese Navy type designation, Type 0 carrier fighter (Rei shiki Kanjō sentōki, 零式艦上戦闘機), taken from the last digit of the Imperial year 2600 (1940) when it entered service. In Japan, it was unofficially referred to as both Rei-sen and Zero-sen; Japanese pilots most commonly called it Zero-sen, where sen is the first syllable of sentōki, Japanese for "fighter plane".

In the official designation "A6M", the "A" signified a carrier-based fighter, "6" meant that it was the sixth such model built for the Imperial Navy, and "M" indicated Mitsubishi as the manufacturer.

The official Allied code name was "Zeke", in keeping with the practice of giving male names to Japanese fighters, female names to bombers, bird names to gliders, and tree names to trainers. "Zeke" was part of the first batch of "hillbilly" code names assigned by Captain Frank T. McCoy of Nashville, Tennessee (assigned to the Allied Technical Air Intelligence Unit (ATAIU) at Eagle Farm Airport in Australia), who wanted quick, distinctive, easy-to-remember names.

The Allied code for Japanese aircraft was introduced in 1942, and McCoy chose "Zeke" for the "Zero". Later, two variants of the fighter received their own code names. The Nakajima A6M2-N floatplane version of the Zero was called "Rufe", and the A6M3-32 variant was initially called "Hap". General "Hap" Arnold, commander of the USAAF, objected to that name, however, so it was changed to "Hamp".

Sub-Lieutenant Saburō Sakai (坂井 三郎, Sakai Saburō, 25 August 1916 – 22 September 2000) was a Japanese naval aviator and flying ace ("Gekitsui-O", 撃墜王) of the Imperial Japanese Navy during World War II. Sakai had 28-64 aerial victories (including shared) by official Japanese records, while his autobiography Samurai!, co-written by Martin Caidin and Fred Saito, claims 64 aerial victories. Such discrepancies are common, and pilots' official scores are often lower than those claimed by the pilots themselves, due to difficulties in providing appropriate witnesses or verifying wreckage, and variations in military reports due to loss or destruction.

On 3 August 1942, Sakai's air group was relocated from Lae to the airfield at Rabaul.

On 7 August, word arrived that U.S. Marines had landed that morning on Guadalcanal. The initial Allied landings captured an airfield, later named Henderson Field by the Allies, that had been under construction by the Japanese. The airfield soon became the focus of months of fighting during the Guadalcanal Campaign, as it enabled U.S. air power to hinder the Japanese attempts at resupplying their troops. The Japanese made several attempts to retake Henderson Field, resulting in continuous, almost daily air battles for the Tainan Kōkūtai.

U.S. Marines flying Grumman F4F Wildcats from Henderson Field on Guadalcanal were using a new aerial combat tactic, the "Thach Weave", developed in 1941 by the U.S. Navy aviators John Thach and Edward "Butch" O'Hare. The Japanese Zero pilots flying out of Rabaul were initially confounded by the tactic. Saburō Sakai described their reaction to the Thach Weave when they encountered Guadalcanal Wildcats using it:

"For the first time Lt. Commander Tadashi Nakajima encountered what was to become a famous double-team maneuver on the part of the enemy. Two Wildcats jumped on the commander's plane. He had no trouble in getting on the tail of an enemy fighter, but never had a chance to fire before the Grumman's team-mate roared at him from the side. Nakajima was raging when he got back to Rabaul; he had been forced to dive and run for safety."

On 7 August, Sakai and three pilots shot down an F4F Wildcat flown by James "Pug" Southerland, who by the end of the war became an ace with five victories. Sakai, who did not know Southerland's guns had jammed, recalled the duel in his autobiography:

"In desperation, I snapped out a burst. At once the Grumman snapped away in a roll to the right, clawed around in a tight turn, and ended up in a climb straight at my own plane. Never before had I seen an enemy plane move so quickly or gracefully before, and every second his guns were moving closer to the belly of my fighter. I snap-rolled in an effort to throw him off. He would not be shaken. He was using my favorite tactics, coming up from under."

They were soon engaged in a skillfully maneuvered dogfight. After an extended battle in which both pilots gained and lost the upper hand, Sakai shot down Southerland's Wildcat, striking it below the left wing root with his 20 mm cannon. Southerland parachuted to safety.

Sakai was amazed at the Wildcat's ruggedness:

"I had full confidence in my ability to destroy the Grumman and decided to finish off the enemy fighter with only my 7.7 mm machine guns. I turned the 20 mm cannon switch to the 'off' position and closed in. For some strange reason, even after I had poured about five or six hundred rounds of ammunition directly into the Grumman, the airplane did not fall, but kept on flying.

I thought this very odd — it had never happened before — and closed the distance between the two airplanes until I could almost reach out and touch the Grumman. To my surprise, the Grumman's rudder and tail were torn to shreds, looking like an old torn piece of rag. With his plane in such condition, no wonder the pilot was unable to continue fighting! A Zero which had taken that many bullets would have been a ball of fire by now."

Not long after he downed Southerland, Sakai was attacked by a lone Douglas SBD Dauntless dive bomber flown by Lt. Dudley Adams of Scouting Squadron 71 (VS-71) from USS Wasp. Adams scored a near miss, sending a bullet through Sakai's canopy, but Sakai quickly gained the upper hand and succeeded in downing Adams. Adams bailed out and survived, but his gunner, R3/c Harry Elliot, was killed in the encounter. According to Saburō Sakai this was his 60th victory.

Sakai's comments in the last paragraph were prophetic about one of the big reasons U. S. naval aviation ultimately prevailed over the Japanese in WW2.

Below is a simulation video of Sakai's dogfight with Southerland I stumbled on a while back. 


Some of the Japanese-created computer simulations of historical events are quite good and this is certainly one of them.

Yep, it was a great thread, thanks everyone!
