Nonetheless it had shared many of the characteristics of early Caudron designs, with unequal span, two spar wings and open frame fuselages bearing twin fins and rudders.
A 150 kW (200 hp), twenty cylinder, four-row air-cooled Anzani 20 radial engine was mounted in pusher configuration centrally between the wings, driving a propeller between the twin tailbooms.
A cylindrical petrol tank was mounted laterally ahead of the engine and over the wing leading edge, at the back of a short fuselage pod in which the crew of two sat side-by-side in an open cockpit.
[1] The rear part of the Type K's fuselage was an open structure with two girders, each vertically cross braced and converging in profile, parallel to each other in plan and cross-linked horizontally at the tail.
Though not an amphibian, the Type K, classified as an avion de bord, could take-off from a wooden runway using a pair of discardable bogies and it won a prize of 6,000 Francs by getting aloft after a 35 m (115 ft) run.
