The B-36F was an improved version of the B-36D. More powerful Pratt & Whitney R-4360-53 radial engines of 3,800 hp each replaced the -41 engines of the D model. The increased power allowed the F to fly to a maximum speed of 417 mph.

Thirty four B-36Fs were built in four production blocks and carried 1949 and 1950 serial numbers. Various avionics improvements included an improved radar bombing system (K-3A) and a new defensive fire control radar system (AN/APG-32 and later AN/APG-32A). Chaff (radar reflective metallic strips) dispensers were also installed to confuse enemy radar by creating large/false radar returns.

Like most B-36 series aircraft, some F models were modified to Featherweight II or III specifications. The Featherweight III program eliminated all defensive armament except for the two 20mm cannons in the tail along with most of the defensive fire control system.

One B-36F (S/N 49-2677) was modified for use as a carrier for the XB-58 test program. The main fuselage and wing structure was carried in the bomb bay.
