Interesting. In my experience the 104 didn't have any hard points to mount such a bomb on, the wings were only about 8 0r so feet from tip to root. It's a moot point any way. Even the Navy wouldn't be silly enough to try and take one off a carrier, let alone land one. Indeed it should have read F-4. However, even F-4s didn't routinely go nuc armed in an air defense role. That takes specific release from the NMCC.

This one was used too - the B61:

The nuclear information comes from the US's own investigation into the why the planes were recalled.
