The Thach Weave (also known as a Beam Defense Position) is an aerial combat tactic developed by naval aviator John S. Thach of the United States Navy soon after the United States' entry into World War II.
Thach had heard, from a report published in the 22 September 1941 Fleet Air Tactical Unit Intelligence Bulletin, of the Japanese Mitsubishi Zero's extraordinary maneuverability and climb rate. Before even experiencing it for himself, he began to devise tactics meant to give the slower-turning American F4F Wildcat fighters a chance in combat. Every evening while he was based in San Diego, he would think of different tactics that could overcome the Zero's maneuverability, and tested them in flight the following day.
Working at night with matchsticks on the table, he eventually came up with what he called "Beam Defense Position", but which soon became known as the "Thach Weave". It was executed either by two fighter aircraft side-by-side or by two pairs of fighters flying together. When an enemy aircraft chose one fighter as his target (the "bait" fighter; his wingman being the "hook"), the two wingmen turned in towards each other. After crossing paths, and once their separation was great enough, they would then repeat the exercise, again turning in towards each other, bringing the enemy plane into the hook's sights. A correctly executed Thach Weave (assuming the bait was taken and followed) left little chance of escape to even the most maneuverable opponent.

Thach called on Ensign Edward "Butch" O'Hare, who led the second section in Thach's division, to test the idea. Thach took off with three other Wildcats in the role of defenders, Butch O'Hare meanwhile led four Wildcats in the role of attackers. Trying a series of simulated attacks, Butch found that in every instance Thach's fighters had either ruined his attack or actually maneuvered into position to shoot back. After landing, Butch excitedly congratulated Thach: "Skipper, it really worked. I couldn't make any attack without seeing the nose of one of your airplanes pointed at me."
The tactic was first tested in combat by Thach during the Battle of Midway, when his flight of four Wildcats was attacked by a squadron of Zeroes. Thach's wingman, Ensign R. A. M. Dibb, was attacked by a Japanese pilot and turned towards Thach, who dove under his wingman and fired at the incoming enemy aircraft's belly until its engine ignited.
The maneuver soon became standard among US Navy pilots and was adopted by USAAF pilots.
Marines flying Wildcats from Henderson Field on Guadalcanal also adopted the Thach Weave. The Japanese Zero pilots flying out of Rabaul were initially confounded by the tactic.
Saburō Sakai, the famous Japanese ace, relates their reaction to the Thach Weave when they encountered Guadalcanal Wildcats using it:[1]
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.
The maneuver was so effective that it was used by American pilots during the Vietnam War, and is still an applicable tactic today.[citation needed]
