Proposed 'escort' gunship version, based on the E-1. Classified as a WaffentrÐ´ger ("weapons carrier") by the RLM, which the WT suffix denoted, in a similar role to that of the American Boeing YB-40 Flying Fortress "gunship" conversion for the USAAF. Primary mission was to provide normal 323 cargo formations with heavy defensive protection. No cargo carrying ability. "Solid" nose with 20mm cannon turret, two additional wing turrets plus up to ten other machine guns and cannon of varying calibres firing from standard and new waist/beam positions. 1.3 tonnes of armour plating was added across the entire airframe. To operate the weapons the crew increased to twenty-one. Two prototypes built and tested, but series was cancelled after it was judged that normal single-engined fighters were more effective in the transport escort role. One of the prototypes was briefly assigned to KG 200 for operational evaluation, where it flew armed escort for the small number of captured B-17 Flying Fortresses operated by the Geschwader.
