KC-135T Stratotanker walk around
The 171st ARW at Pittsburgh operates the KC-135T variant of the venerable Stratotanker, these aircraft among those formerly used for SR-71 support as KC-135Qs. These tankers carried the exotic JP-7 fuel for the Blackbird in their fuselage tanks. After the SR-71’s retirement, the KC-135Qs were put through the KC-135R rebuilding program with CFM56 engines, but are still somewhat different from the standard R-model, with separate refueling ports for the wing and fuselage tanks, as well as a tail mounted searchlight.
