The C.IV was designed as a reconnaissance biplane with a fixed tailwheel landing gear and was originally powered by the Napier Lion piston engine.

Twenty aircraft were licensed built in Spain by the Talleres Loring company for the Spanish Army's Aeronáutica Militar.

They took off from Tacoma, Washington and started to head north, but made it only about 100 miles of the way to Vancouver, British Columbia when the engine vapor locked and forced a landing in a field.

When they got back in the air, they started heading for nearby Ladner Field, Vancouver to top off the tanks, but they crashed upon landing and decided to give up.
