The E-Club is a long-standing organization that has it's roots in a company called E-Systems that operated out of Majors Field in Greenville, Texas. It started as a non-profit activities club for employees of E-Systems. The name of the company has changed many times. Today it is part of L3Harris.

The E-Club remains a non-profit activities club, but it is not supported by L3Harris. While the activity groups that belong to the E-Club have a majority membership of L3Harris employees, you do not need to be an employee of L3Harris to benefit from the club.
