Secret underground tunnel to Nazi nuclear test site found in Upper Austria ?

[Lief 🗽]

Possibly the Nazis might have progressed to the point of being able to build a crude reactor, but even had they developed bombs equivalent to Fat Man or Little Boy, they didn't have a delivery system able to carry such heavy bombs.  The best they could have done would have been to use it to as basically an atomic mine, hiding a bomb that would be blown up once the enemy had taken the area.  Maybe detonate it in Berlin itself as part of the Nero Decree.

You couldn't stick one on a V2?
