Ago C.Iw

   The Ago C.Iw used a standard C.I airframe with a robust float undercarriage instead of wheels.
   One airframe, Marine Number 115, was built. Power was from a 150 hp Benz Bz.III, the same engine that powered many standard C.I aircraft, that used the early production side radiators.
   The aircraft was naval category CB, which means an armed two-seater (it had a flexible machine gun in the observer's cockpit) with bombing equipment.
   After evaluation at the SVK test center the C.Iw was assigned to Zeebrugge for operational evaluation and arrived there in July 1915.


Ago C.IIw
  
   The Ago C.IIw was a floatplane adaptation of the three-bay Ago C.II. Engine power was a 200 hp Benz Bz.IV. Only two aircraft, Marine Numbers 539 and 586, were built.
