Again without using Google, what's special about the KC-135D?
KC-135D All four RC-135As (Pacer Swan) were modified to partial KC-135A configuration in 1979.[42][43] The four aircraft (serial numbers 63-8058, 63-8059, 63-8060 and 63-8061) were given a unique designation KC-135D as they differed from the KC-135A in that they were built with a flight engineer's position on the flight deck.[44] The flight engineer's position was removed when the aircraft were modified to KC-135 standards but they retained their electrically powered wing flap secondary (emergency) drive mechanism and second air conditioning pack which had been used to cool the RC-135As on-board photo-mapping systems.[45] Later re-engined with Pratt & Whitney TF33 engines and a cockpit update to KC-135E standards in 1990 and are were retired to the 309th AMARG at Davis-Monthan AFB, AZ in 2007

That was the KC-135A.

There were some interesting differences because of that letter. They looked identical externally, except the D model had a camera window low on the side.
Internally they had an extra position in the cockpit, electric flap motors, and extra cooling systems.

Specially segregated tanks allowing it to carry both JP-7 for the SR-71 (and others) and standard JP-4.
