To me, the real Tempest has got the Napier Sabre engine - like the Typhoon.
The engine is propably the reason, why none is flying today. Extremely tempered, and more or less impossible to get maintained/overhauled anywhere.
The Mark II with the Centaurus engine is another story. And is is strange, that no Tempest II is flying today. Especially when the Sea Fury, with the same engine, is pretty common today.
