The Shane Airworks Snámhán was a large, heavy floatplane in service with the SDF-Navy and SDF-Army from 1933 to 1942. From sixty originally ordered, only 28 were delivered in the end. Starting 1942, they were replaced by the Monarcha M-29 Prásóg.
The Snámhán was the first nail in the coffin of Shane Airworks.
The Shane Airworks Snamhan was the second large monoplane flying boat, said wings being parasol wings, constructed by the company, which, before, almost exclusively relied on biplane flying boats, when it approached that size. It was supposed to match many of its four-engined competitors and to be cheaper in both acquisition and upkeep, ideal for the young SDF-Navy, which, after witnessing the test flights of the prototype in 1931, ordered a total of 60 aircraft for five squadrons, which soon began to form the backbone of the SDF-Navy's maritime patrol capabilities.
However, the Snamhan suffered from being underpowered and was plagued with structural problems. Crews however, could rest assured, that their hull floated quite well. On one occassion, the crew 'comissioned' their wingless Snamhan as SDFS Snamhan in gallow's humour while floating on the Great Sea. The SDF-Navy only took 28 of the aircraft.
Also used, on several occassions, to rescue downed pilots, the Snamhan was soon supplemented and soon replaced by other, more modern and stronger aircraft.
