John Thach

John Smith Thach (April 19, 1905 – April 15, 1981) was a World War II Naval Aviator, air combat tactician, and United States Navy admiral. Thach developed the Thach Weave, a combat flight formation which could counter enemy fighters of superior performance, and later the big blue blanket, an aerial defense against kamikaze attacks.

Early career John S. Thach was born in Pine Bluff, Arkansas, on April 19, 1905. He graduated from the United States Naval Academy in 1927 and spent two years serving in battleships, before becoming a Naval Aviator in early 1930. His USNA classmates included William Brockman, Creed Burlingame, and Eugene Lindsey. Thach spent the next decade serving as a test pilot and instructor and establishing a reputation as an expert in aerial gunnery. On the morning of June 4, Thach led a six-plane sortie from VF-3, escorting twelve Douglas TBD Devastators of VT-3 led by Lieutenant Commander Lance Massey from Yorktown, when they discovered the main Japanese carrier fleet. They were immediately attacked by 15 to 20 Japanese fighters. Thach decided to use his namesake maneuver, marking its first combat usage. Although outnumbered and outmaneuvered, Thach managed to shoot down three Zeros and a wingman accounted for another, at the cost of one Grumman F4F Wildcat.

After Midway, Thach was assigned to instruct other pilots in combat tactics. The United States Navy pulled its best combat pilots out of action to train newer pilots, while the Japanese kept their best pilots in combat. As the war progressed, the Japanese Navy lost their experienced pilots due to attrition and had no well-trained replacements, while the United States was able to improve the general fighting ability of their own personnel. When the Japanese resorted to the feared Kamikaze suicide attacks, Thach developed the "big blue blanket" system to provide an adequate defense.

Later in the war, Commander Thach became operations officer to Vice Admiral John S. McCain Sr., commander of the Fast Carrier Task Force. which was a primary focus at the time in the ongoing Cold War. An annual award was later established in his name for presentation to the top ASW squadron in the navy.

Thach was promoted to vice admiral in 1960 and served as the Deputy Chief of Naval Operations for Air in the Pentagon, where he presided over development of the A-7 Corsair II, among other naval aviation programs. As Commander in Chief, United States Naval Forces Europe, starting in 1965, he pinned on his fourth star as a full admiral, retiring from the Navy in May 1967 from that position.

The Arkansas Aviation Historical Society inducted Thach into the Arkansas Aviation Hall of Fame in 1981.

Thach died on April 15, 1981, in Coronado, California, four days before his 76th birthday, and was buried at Fort Rosecrans National Cemetery in San Diego.

The frigate was named in his honor.
