Club's most fruitful periods were during the 1970s and 2000s when the club spent six, respectively five seasons in the second tier of the Romanian football league system. The best ranking of Cetate Deva was a 4th place at the end of the 1973–74 Divizia B season, period when the club was managed by Ladislau Vlad.
Over time the club suffered several re-foundations, from two mergers (with Vega Caransebeș in 1994 and with CS Certej in 2003) to two re-establishments (as CS Mureșul Deva in 2006 and as CNS Cetate Deva in 2013).
