The T23 Medium Tank was a prototype tank that was produced in limited numbers by the United States during World War II.

Artist's view !
The T23 was not adopted for service partly because the Army Ground Forces did not want to disrupt M4 production.
Overall the T23 could not be considered a successful medium tank, but it did pave the way for development of the T25 Medium Tank, and then the M26 Pershing.
