nuclear strategy The explosion from the first thermonuclear weapon (hydrogen bomb), code-named Mike, which was detonated at Enewetak atoll in the Marshall Islands, November 1, 1952. The photograph was taken at an altitude of 3,600 metres (12,000 feet) 80 km (50 miles) from the detonation site.

The nuclear triad consists of three distinct platforms: land-based intercontinental ballistic missiles (ICBMs), nuclear-missile-armed submarines, and strategic aircraft equipped with nuclear bombs and missiles.1

By distributing nuclear assets across these diverse platforms, a nation makes its total force significantly more difficult to destroy in a single first strike. This diversification ensures that even if one component is compromised, the others remain operational to launch a secure second strike.12

This redundancy is a fundamental pillar of mutually assured destruction, as it guarantees that an aggressor cannot eliminate a country's ability to retaliate, thereby serving as a powerful deterrent against nuclear conflict. While this strategy was central to Cold War military planning, it remains a component of modern defense strategy, albeit with reduced arsenals.1
