During which conflict did Navy Divers primarily focus on underwater wire tapping?

The focus on underwater wire tapping by Navy Divers primarily occurred during the Cold War. This period, characterized by heightened tensions and military competition between the United States and the Soviet Union, saw an increased emphasis on intelligence gathering and surveillance activities. The strategic importance of underwater operations led to the development of techniques for tapping underwater communication lines, particularly in response to the advancements in submarine and counter-submarine warfare.

During the Cold War, Navy Divers were specifically trained in skills that included reconnaissance and monitoring of enemy communications, making underwater wire tapping a key component of their operations. This was essential for obtaining valuable intelligence, which aided in devising tactics and strategies against potential threats. In contrast, the other conflicts listed did not see such a concentrated focus on these types of underwater intelligence activities, which were a hallmark of the Cold War's geopolitical landscape.
