Every cargo plane that flies out of Incirlik needs to carry an extra passenger or two. Every flight, every day.
It wont take long to ship 50 nukes. Just dont tell anybody, ESPECIALLY the Turks. They probably have plans for those warheads.
Considering the size and weight of these old style weapons, moving them in this manner would not be practical. Also, the base is full of Turkish workers and most of them are likely government workers. Secrecy is out of the question. Our options are very limited.
Its my understanding these nukes are tacticals, not big strategic devices, so they probably arent all that big. You can probably fit a few of them into a single truck.
Getting those nukes from their bunkers to the flight line might be tricky, but only if we let the Turks see what were doing. Im convinced the Turks want those nukes to stay, and not for deterrent effect.
