 Powered by a water-cooled 490 kW (660 hp) BMW VIu 7.3Z V12 engine, the L 84 had a fabric-covered fuselage constructed of welded steel tubes, and wooden wings skinned with plywood.Its armament comprised three 7.92 mm (.312 in) machine guns, two in fixed forward-firing positions and the third ring-mounted in the aft cockpit.Only the first prototype was completed before Albatros became part of Focke-Wulf, and this was destroyed during flight testing.
