JPTS is the high altitude fuel used in the U-2 aircraft. It's likely a rarity now (TS = thermally stable). When the air force was still using the U-2 hot & heavy, this fuel was only blended by two refineries in the whole world and it cost about 3-times more than JP-8 that the US Air Force used for there normal flight operations. JP-8 is a lot like the civilian Jet A-1.

When I was in the army, all we ever carried in the tankers for refueling helicopters was JP-4 and as far as I know it's still in use by the US Army.
