A technical analysis of the Battle of Okinawa, describing Japanese air tactics, with accurate data, strategies, and strategic military significance.
The Battle of Okinawa was one of the fiercest battles of World War II. Over a period of more than two months, Japanese forces deployed Japanese air tactics in 1945, including intense kamikaze attacks against US air and naval forces during the Battle of Okinawa.
The strategic context of the Battle of Okinawa
The operation took place from April 1 to June 22, 1945. It mobilized nearly 1,827 bombers and fighters, a large number of which were dedicated to kamikaze operations during World War II, as part of Operation Kikusui. These attacks were intended to inflict heavy losses on the US air and naval forces during the Battle of Okinawa. In terms of human casualties, the US lost more than 12,000 killed, with over 49,000 casualties in all categories.
The scale of Japanese aircraft sorties in Okinawa
Between April and June, the Japanese carried out up to 3,000 air sorties, including around 400 kamikaze attacks specific to Okinawa. More broadly, from late 1944 to the end of the campaign, 2,550 kamikaze missions were launched, with an efficiency rate of approximately 18.6% (i.e., 475 hits or near misses). In comparison, other sources cite a total of 4,000 kamikaze sorties during the war, sinking approximately 38 US ships and damaging 368 others, with 4,900 sailors killed.
Japanese air tactics and their implementation
The kamikaze attacks on Okinawa, known as Operation Kikusui, were carried out in several massive waves. Starting on April 6, the first wave included 215 Navy aircraft and 82 Army aircraft, targeting mainly destroyers in advanced radar stations. This tactic exploited surprise, low-altitude flight, sudden changes in trajectory, and the use of clouds as cover to thwart American defenses.
The concrete impact on American ships
Although no battleships or aircraft carriers were sunk, the damage was severe. Up to 30 ships were sunk and 368 damaged, including battleships, aircraft carriers, cruisers, and destroyers. The suicide planes mainly targeted the destroyers at the front of the line, which were crucial for radar and early warning. During Operation Kikusui, more than 700 aircraft were lost and 3,860 crew members lost their lives. The human toll was heavy: more than 7,000 Allied sailors were killed and 328 ships were hit (36 sunk and 218 damaged).
The real effectiveness of kamikaze attacks against the US fleet
Subsequent analyses show that these tactics inflicted serious losses but were insufficient to turn the tide of the war. Of the 2,550 missions undertaken between October 1944 and June 1945, only 18.6% were deemed effective. Furthermore, even when aircraft carriers such as the Bunker Hill, Franklin and Enterprise were severely damaged, their loss did not structurally affect the US fleet.
Types of aircraft and units involved
The kamikaze aircraft included a variety of models: Mitsubishi A6M “Zero,” Aichi D3A “Val,” Mitsubishi G4M “Betty,” Nakajima B5N “Kate,” Yokosuka P1Y “Francis,” and even other military aircraft such as the Kawasaki Ki-61 ‘Tony’ and Mitsubishi Ki-46 “Dinah.” Faced with the urgency of the situation, even training aircraft were converted into kamikaze planes, illustrating the scarcity of resources.
Strategic summary — human and symbolic costs
The Battle of Okinawa, marked by these suicide attacks against American ships, illustrates both the strategic determination of the Empire of the Rising Sun and the exhaustion of its air resources. Although destructive, the Japanese air operations in 1945 were unable to reverse the balance of power. Nevertheless, they caused significant American naval losses in Okinawa and highlighted the cruelty of a doctrine based on absolute sacrifice.
A symbolic initiative: compassion in the midst of conflict
A notable episode occurred on April 11, 1945, when a kamikaze pilot crashed into the USS Missouri. The ship’s captain ordered a military funeral at sea under an improvised Japanese flag—a rare and poignant gesture symbolizing a form of human respect amid the chaos of war.
The Battle of Okinawa was fought amid fierce air combat and precise kamikaze tactics. The kamikaze attacks of 1945 inflicted significant damage on the US fleet, but did not break the US air and naval forces during the Battle of Okinawa. The Japanese approach cost thousands of lives and tons of flying metal, demonstrating both the strategic horror and human tragedy of the final phase of the Pacific campaign in 1945.
