Key Takeaways:

The Piper PA-48 Enforcer was a unique turboprop attack aircraft developed from the WWII-era P-51 Mustang concept.
The project began with Trans Florida Aviation's "Cavalier Mustangs," which were modified P-51s, before Piper Aircraft acquired the turboprop variant rights.
Piper heavily re-engineered the design, incorporating powerful turboprop engines and a significantly modified airframe, resulting in a PA-48 that shared less than 10% parts commonality with the original P-51.
Despite being designed for ground attack and successfully demonstrating its capabilities, the U.S. military ultimately did not adopt the PA-48 Enforcer, and its prototypes were retired to museums.

Over the years, many aircraft types have evolved into far more capable machines by having their existing piston engines replaced with turboprop powerplants. The Piper Malibu, for example, gained better performance and reliability when the turboprop variant was introduced as the Meridian—now the M600. Similarly, the Beechcraft Queen Air, deHavilland Beaver, and Douglas DC-3 all saw corresponding performance gains as turbine-powered derivatives.

Decidedly less common is the initiative to reimagine a World War II-era fighter as a modernized, turboprop attack aircraft and market it to the government. This, however, is precisely what happened in the form of the Piper PA-48 Enforcer. First flown in 1971, a total of four prototypes were built and demonstrated until their retirement in 1984.
