During the war in Southeast Asia, U.S. Air Force fighter pilots and crewmen were repeatedly challenged by enemy MIG's in the skies over North Vietnam. The air battles which ensued were unique in American history because U.S. fighter and strike forces operated under stringent rules of engagement. With periodic exceptions, for example, MIG bases could not be struck. The rules generally forbade bombing or strafing of military and industrial targets in and around the enemy's heartland, encompassing the capital of Hanoi and the port city of Haiphong. These restrictions gave the North Vietnamese substantial military advantage. Free from American attack and helped by its Soviet and Chinese allies, the enemy was able to construct one of the most formidable antiaircraft defenses the world has even seen. It included MIG forces, surface-to-air missile (SAM) batteries, heavy concentrations of antiaircraft artillery (AAA) units, and an array of early warning radar systems. These elements sought to interdict and defeat the U.S. bombing campaign against North Vietnam's lines of communication and its military and industrial base. The primary mission of U.S. fighter pilots was to prevent the North Vietnamese MIG's from interfering with U.S. strike operations. This book tells how American airmen-assisted by an armada of other USAF aircraft whose crews refueled their planes, warned of approaching enemy MIG's and SAM's, and flew rescue missions when they were shot down managed to emerge from their aerial battles with both victories and honor.
