giving a poor view. The undercarriage consisted of a sprung strut carrying two mainwheels underneath the engine, with two stabilising wheels at the wingtips of the lower wing, with a tailskid just aft of the trailing edge of the lower wing. This design never flew, with the head of
Armstrong Whitworth's Aircraft department, I. Fairbairn-Crawford, forbidding test flights.

gunners sat behind and outboard the propeller (and less than 2 ft (0.6 m) from the exhaust manifold). The fuselage was much deeper than the F.K.5, filling the gap between the middle and lower wings, giving a slightly better view, while the undercarriage had two pairs of wheels with a narrow track under the fuselage and a more conventional tailskid.

Koolhoven completely reworked the design to produce the F.K.6. While still a triplane with the middle wing of significantly greater span than the upper and lower wings, it was larger, with two-bay wings. This time, the gunner's nacelles were slung under the middle wing and were shorter, so that the

No definitive list exists of the true sequence of the F.K. designations as applied by
Koolhaven to his designs. While the escort triplanes were probably designated F.K.5 and F.K.6, and were earlier in design than the
