During World War II, the first generation of guided bombs was developed as nations sought ways to improve bombing accuracy against heavily defended or high-value targets. Early examples included Germany’s Fritz X, a radio-guided armor-piercing bomb used against warships; the American GB-4, one of the first U.S. television-guided glide bombs; the AS-2 BAT, a radar-guided glide bomb designed to autonomously home in on naval targets; and Japan’s Ki-148, a radio-controlled guided bomb intended for precision attacks. Together, these weapons marked the transition from unguided gravity bombs to the precision-guided munitions that define modern air warfare.
