Since the Enforcer was never in the Air Force inventory, it was
not given an official military designation and did not receive
an Air Force serial number.
Piper PA48 Enforcer
The Enforcer was a turboprop powered, light, close-support,
ground-attack aircraft built by Piper and based on the
P-51 Mustang. It closely resembles the P-51 but was a new aircraft.
The Air Force did not order the Enforcer.
