 | | Underwater testing results from nuclear devices being detonated underwater, usually moored to a ship or a barge (which is subsequently destroyed by the explosion). |
 | | Tests of this nature have usually been conducted to evaluate the effects of nuclear weapons against a Navy (such as in Operation Crossroads), or to evaluate potential sea-based nuclear weapons (such as nuclear torpedoes or depth-charges). |
 | | Neither country had very many nuclear weapons to spare at first, and so testing was relatively limited (when the U.S. used two weapons for Operation Crossroads in 1946, they were detonating over 20% of their current arsenal). |
