The Alter A.1 was a single-seat biplane fighter aircraft first flown in February 1917. Built by Ludwig Alter-Werke of Darmstadt to a design by Kallweit and Ketterer, the A.1 was very similar in concept to the Nieuport 11, but not an exact copy.
Design and development
Powered by a 110 hp Goebel Goe II 7-cylinder rotary engine, the A.1 had I-type inter-plane struts and a wood-framed, fabric and plywood covered fuselage, armed with twin, synchronised 7.92 mm LMG 08/15 machine guns.
Development was halted following demonstration to the Idflieg (Inspektion der Fliegertruppe), who judged its performance inadequate and its construction overly flimsy.
