"Clive Cussler found the H.L. Hunley in similar conditions..."
I think some other guy is claiming he found it first, like 25 years before Cussler, and has some documentatin. Either way, it was found, which I guess was your point.

I agree. I am convinced that Lee Spence found the Hunley in 1970 -- and documented and reported his findings. Here is a whole collection of articles on the Spence/Cussler Hunley controversy .
My point was that Cussler systematically searched a large area -- using modern technology (magnetometers and side-scan sonar) -- and he successfully (re) located the Hunley.
If the USAF really wanted to locate the Tybee Island "Broken Arrow", the (magnetometer) technology is available to do so. IMHO, radioactivity detection would be the appropriate tool to verify that a mag anomaly was, indeed, the bomb -- not a primary search tool.
