Vultee XA-41

The Vultee XA-41 was originally ordered as a dive bomber.

 After combat experience led the Army Air Corps to believe dive-bombers were too vulnerable to enemy fighters, the contract was amended to change the role to low-level ground attack.

Although the XA-41 was a potent weapons system, the design was overtaken by more advanced technology, and never entered production.
