P-40R Warhawk

The designation P-40R was assigned to P-40F and P-40L airframes that had their Packard Merlin engines replaced in service with Allison V-1710-81 engines. Converted P-40Fs were redesignated P-40R-1, converted P-40Ls as P-40R-2. These planes were used exclusively for training duties. US Army documents claim that over 600 such conversions were made, but only 70 P-40F and 53 P-40L conversions can be confirmed:
