Which WWII battle resulted in a fierce island assault and provided critical airfields close to Japan?

• A. Midway
• B. Okinawa
• C. Iwo Jima
• D. Guadalcanal

Answer: (C)

Securing airfields on a captured island close to Japan was a pivotal way to boost long-range air power and protect bombers striking the Japanese home islands. The battle for Iwo Jima fits this idea especially well: American and Japanese forces fought a brutal, sustained island assault to seize two airfields that could support B-29 bomber operations and provide fighter coverage for missions into Japanese airspace. Controlling those airfields meant bombers could fly farther, face less risk returning, and keep up pressure on Japan, a strategic gain that shaped the air war over the homeland.

Midway was primarily a naval turning point rather than an island-taking operation aimed at securing near-Japan airfields. Guadalcanal involved hard fighting and valuable airfields earlier in the war, but its airfield strategy and location did not have the same direct leverage for the long-range, near-Japan bombing campaign as Iwo Jima. Okinawa was another fierce island battle with airfields, but the decisive link to enabling sustained air operations over Japan is most famously associated with the capture of Iwo Jima.
