The Shane Airworks Débheathach was a small reconnaissance biplane floatplane, produced from 1934 to 1938. By the time of its introduction, it was already obsolete.
Useable as a spotter for artillery, reconnaissance plane and liason aircraft, the Débheathach was armed with three Gabha R-22 Machine Guns, one in the back cockpit, the other two forward facing. A rugged, yet rather incapable aircraft, the Débheathach had rather poor sea-handling and had issues with the wings, that could be folded, the gull upper wings and the inverse lower wings sometimes not connecting correctly to the fuselage again.
Built of steel tubes with wood, covered by fabric, the plane was at least cheap.
Built for the specifications of the SDF-Navy, the Débheathach was set to equip the Rhiannon-class Light Cruisers and Miodóg-class Sloops, as well as shore installations and the seaplane tender SDFS Faoileán, but it quickly fell out of favour as Mark I proved to be a failure. The problems with Mark I were at some point so bad, that the SDF-Navy pulled all Débheathachs from their cruisers and sloops in favour of the more reliable Shane Airworks Piongain.
