The M65 280mm Atomic Cannon

Video of test firing a nuclear warhead

Click on the link to see and hear a video excerpt of the only live fire test of a 15 kiloton nuclear warhead fired in the Nevada desert in 1953. Please note: the sepia-toned blast-effects footage in the video clip is almost certainly not from this test, but from earlier nuclear tests.

M65 in motion and deployed

Click on the title above to see a different film of the same atomic test firing. This YouTube video shows two M65s in motion and being deployed at the site for Upshot/Knothole, test Grable. Not as good visual quality as the video above, and with a scratchy sound track, but interesting to see the M65 in motion and being emplaced.
