To adapt it for wartime service, hardpoints were added to the wings for bombs, the fuselage was strengthened and extended to create more space. Fore and aft dorsal gun positions were added, in addition to an extended-length version of the "Bola" ventral gondola typical of World War II German bomber aircraft; incorporating a central bomb bay (usually used for additional long-range fuel tanks), as well as heavily glazed fore and aft ventral flexible machine gun emplacements at either end. The extra weight introduced by its military equipment meant that some early Fw 200 aircraft broke up on landing, a problem that was never entirely solved. Later models were equipped with Lorenz FuG 200 "Hohentwiel" low UHF-band ASV radar in the nose. In 1943 a version entered service that could carry the Henschel Hs 293 guided missile, mandating fitment of the associated "Funkgerät" FuG 203 "Kehl" radio guidance gear on a Condor to steer them.
