Design and development
A development of the FBA Type A, the Type H shared the same basic pusher biplane configuration, but was a larger and heavier machine based on a Donnet-Lévêque design and powered by a water-cooled engine in place of the earlier type's rotary. Most French-built Type H aircraft had water-cooled V-8 Hispano-Suiza 8A variants with powers of 150 or 170 hp (110 or 130 kW), though a minority had 160 hp (120 kW) Lorraine 8Ns.  Some Italian built Type Hs also used the higher-power Hispano motor but more had 180 hp (130 kW) Isotta Fraschini V.4B or 150 hp (110 kW) engines of the same make, both six-cylinder inlines.
The aircraft was a two bay biplane with the smaller span lower wing positioned just above the central fuselage on four supporting struts. There was no stagger and simple parallel interplane struts separated the bays; an extra, outward leaning pair supported the overhanging upper plane on each side. Ailerons were mounted only on this upper wing. The single pusher engine was mounted on struts just below the upper wing, its two blade propeller turning in a cut-out in the wing trailing edges.
The hull of the Type H was, like that of its predecessors, a single step design. A pair of flat bottomed floats, mounted below the outer interplane struts, stabilized the aircraft on the water. Two flight crew members were accommodated side-by-side and a front gunner sat separately in the nose. The rounded, finless rudder mounted above the high tailplane distinguished the Type H from earlier FBA flying boats, which had angular vertical tails.
- Type D
- One Type H was built as a fighter aircraft to class D specifications, equipped with a 37 mm (1.46 in) Hotchkiss gun and powered by a 150 hp (110 kW) Hispano-Suiza 8A or 175 hp (130 kW) Hispano-Suiza 8Aa. Although this was a landplane, its fuselage retained its basic flying boat form. Avion Cannon was its common name, though was also called the FBA 1 Ca2, or Type D cannon fighter. 
- Type S
- The Aviation Maritime issued a Type S specification for a light patrol bomber to be powered by a 200 hp (150 kW) Hispano-Suiza 8Bb or 210 hp (160 kW) Hispano-Suiza 8Bbd. Schreck modified a Type H with larger folding wings and longer hull. Entering service in 1917 the Type S flying boats remained in service until 1923, until replaced by Latham and Blanchard flying boats.
The Type H was the major production version of the FBA series and was operated by several air arms during the latter part of the First World War. The great majority served with French and Italian forces. The Escadrille des Hydroviators of the Belgian Air Force was also equipped with the type and one survives on display in the Royal Museum of the Armed Forces and of Military History in central Brussels. Four ex-Italian, Isotta Fraschini powered Type Hs were used by the British Royal Navy as training machines.
From 1926 to at least 1929 twelve FBA Hs were used in Canada by the Compagnie Aerienne Franco Canadienne to make an aerial photographic survey of both cities and countryside.
