In the event of war in the Pacific, the U.S. Navy's task is to?

The U.S. Navy's role in the event of war in the Pacific encompasses a comprehensive strategy that involves multiple responsibilities critical to national security and military effectiveness. The correct answer indicates that all the outlined tasks—protecting supply lines to deployed forces, safeguarding U.S. possessions, and keeping sea-lanes open to allies—must be accomplished.

Protecting supply lines ensures that deployed forces receive essential resources, including ammunition, food, and medical supplies, which are vital for maintaining operational efficiency and readiness in a conflict scenario. Safeguarding U.S. possessions, such as territories and bases in the Pacific, is crucial for maintaining a strategic foothold and providing a base of operations for military efforts. Keeping the sea-lanes open to allies is essential for ensuring that allied forces can move troops, equipment, and resources without interference, allowing for coordinated military actions.

Together, these tasks form a cohesive operational strategy that maximizes the effectiveness of the Navy's mission. In the context of a war, they represent interdependent objectives that collectively contribute to the overall success of military operations in the Pacific. Thus, acknowledging that all these responsibilities are important reflects a thorough understanding of maritime strategy and military logistics in the region.
