"Twenty-five Fw-200C-1s were delivered during the second half of 1940 to Kampfgeschwader 40, equipping I Gruppe at Trondheim in Norway and responsible for operations in the far North Atlantic and around the west of Ireland, and III Gruppe at Bordeaux-Merignac flying over the Bay of Biscay and far out into the central North Atlantic. This handful of airplanes - the Condor never had more than 30 aircraft total operational at any one time between November 1940 and the end of 1943 - gave the British fits. Operating beyond the range restrictions of British aircraft, the convoys didn’t have air protection, while the anti-aircraft weapons carried by the escorts and the merchant ships were inadequate for defense against the Condor’s attacks." 276 Condors were built. 365.000 tons of shipping. This proves the theory that a small amount of bombers can do serious damage. Similiar amount of 290's or ME 264's could have done major damage to factories behind Urals. " it was claimed that from June 1940 to February 1941 they sank 365,000 tons." The total may be higher as this figure is only for early part of war.
