The Thach weave is an aerial combat tactic that was developed by naval aviator John S. Thach and named by James H. Flatley of the United States Navy soon after the United States' entry into World War II.
An example of the Thach weave: An enemy following planes A or B is vulnerable to attack from C and D.
John Smith Thach 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.
