An SA-2 SAM explodes under an American plane. The North Vietnamese countered U.S. air superiority by positioning surface-to-air missiles (SAMs) and anti-aircraft artillery (AAA) around high value targets. For propaganda purposes, the North Vietnamese often moved SAM sites to areas that risked collateral damage, near dikes, villages, and stadiums. Although the U.S. developed technology to jam North Vietnamese radar, SAMs and AAA remained a constant danger throughout the war. (Naval History and Heritage Command)
