In late 1928, the Albatros Flugzeugwerke at Johannisthal accepted from the Ernst Heinkel Flugzeugwerke two L.77v tandem two-seat fighter and reconnaissance aircraft that had been built by the latter under Albatros licence. Developed to a Reichswehr contract, the L.77v was a derivative of the L.76 Aeolus trainer and reconnaissance two-seater of 1926 which saw extensive use at the clandestine German flying training school at Lipezk in the Soviet Union (Three of the aircraft saw service performing armament trials in Lipetsk in the Soviet Union; these included one aircraft testing a free-mounted 20 mm cannon.). Possessing an airframe essentially similar to that of the L.76, with two-spar wooden wings primarily plywood covered, N-type interplane struts and a fabric-covered, welded steeltube fuselage, the L.77v was powered by a 600hp BMW VI 5.5 water-cooled 12-cylinder Vee-type engine. Armament comprised two fixed forward-firing 7.9mm machine guns and a similar weapon on a ring mounting in the rear cockpit. One of the L.77v aircraft was destroyed while under test in March 1929. From December 1929, these aircraft were flown from the Erprobungsstelle, or Test Centre, at Staaken, and were retired in October 1931.
