US Marines transported by helicopter to atom bomb test site at Yucca Flat, NV, after bomb is exploded

In the Nevada desert, an atomic device is tested from a 500-foot tower, estimated at 10 kilotons. Following the explosion, radiological safety teams clear the area for a Marine Corps assault using helicopters.

The Marine Corps is perfecting deep penetration tactics, with helicopters replacing landing craft, showcasing military progress in the atomic age.
