Final answer:
The Battle of Iwo Jima was fought to provide a landing strip for strategic bombers, which was crucial for the American forces to advance closer to Japan and intensify aerial assaults on the Japanese mainland.
Step-by-step explanation:
The battle that was fought in order to provide a landing strip for strategic bombers was the Battle of Iwo Jima. This intense confrontation between the United States and Japan was significant due to its strategic location; Iwo Jima was meant to serve as a forward air base for fighter planes, providing cover for long-distance bombers heading towards Japan. American forces suffered heavy losses but successfully captured the island, which provided them a vital base from which to launch further attacks against the Japanese mainland.
