Boeing C-135FR Stratotanker —

That's no A model. Probably an R as it's an Arizona ANG Tanker.

@Paul Barrett Yep, I was going to say the same thing, based on the high-bypass turbofans (for those that don't know the 'R' as I was told stands for 'Re-engined'). The airframe might have been an 'A' at one time. I used to work these at a tower and they are amazingly quiet compared to the old turbojet models with water injection, I got to experience those at KDYS, mother lover they were loud, and trailed smoke like a steam engine.

Thanks all! Not super familiar with military jets.

Super Tanque. Lindo .

I got to ride in my first KC-135 in Jan '66 while going on R&R to Japan from Tan-Son Nhuyet, VN. A sweet flight!
