Following tests both as a floatplane and with a conventional wheeled undercarriage, production orders were placed for two versions both powered by the Maori, the IIIA and IIIB, with 50 and 60 aircraft planned, respectively. The Fairey IIIA was a reconnaissance aircraft intended to operate from aircraft carriers, and as such was fitted with a wheeled or skid undercarriage, while the IIIB was intended as a floatplane bomber, with larger span (increased from 46 ft 2 in/14.19 m to 62 ft 9 in/19.13 m) upper wings and a bombload of three 230 lb (105 kg) bombs.[2] While all 50 IIIAs were built, only 28 of the IIIBs were completed as intended, as a new improved bomber/reconnaissance floatplane, the Fairey IIIC was available, of which 36 were produced, which reverted to short equal-span wings like the IIIA but was powered by the much more powerful and reliable 375 hp (280 kW) Rolls-Royce Eagle VIII engine and could still carry a useful bombload.
