フリッツX
The Germans were first to introduce PGMs in combat, with KG 100 deploying the MCLOS-guidance Fritz X armored glide bomb, guided by the "Kehl-Straßburg" radio guidance system, to successfully attack the Italian battleship "Roma" in 1943, and the similarly "Kehl-Straßburg" MCLOS-guided Henschel Hs 293 rocket-boosted glide bomb (also in use since 1943, but only against lightly armored or unarmored ship targets).
