What was the US strategy in the Pacific to reach Japan?
Leapfrogging
Leapfrogging, also known as island hopping, was a military strategy employed by the Allies in the Pacific War against the Empire of Japan during World War II. The key idea is to bypass heavily fortified enemy islands instead of trying to capture every island in sequence en route to a final target.
Can a submarine destroy an aircraft carrier?
US carriers and their escort ships are armed to the teeth. Submarines are their gravest threat to sinking. Russian subs, for instance, are often armed with 1,000-pound torpedoes that were designed to destroy carrier groups, and it’s conceivable that enough fired at once and on target could sink a carrier.
How do you track a submarine?
Military ASW employs technologies such as magnetic anomaly detectors (MAD), which detect tiny disturbances to Earth’s magnetic field caused by metallic submarine hulls, passive and active sonar sensors that use sound propagation to detect objects underwater, as well as radar and high-resolution satellite imagery to …
How did Japanese avoid detection in Pearl Harbor?
Crossing the North Pacific under radio silence, the task force avoided detection during the ten-day transit. Meanwhile, submarines had already departed home waters and bases in the Marshall Islands.

What did MacArthur’s strategy of island hopping in the Pacific involve?
Island hopping entailed taking over an island and establishing a military base there. The base was in turn used as a launching point for the attack and takeover of another island. Both Nimitz and MacArthur applied leapfrogging and island hopping as major strategies.
