Based in Rome (LIRA) the G.12-Ts maintained urgent aerial communication with Turin (LIMF), Milan (LIML), Sardinia (LIED), and Sicily (LICJ). Once allied controls ended in 1947 three survivors went into civilian markings as I-VIDA, I-VIDI, and I-VIDO, and were then leased to "Avio Linee Italiane" flying the same routes. Returned to government in 1948 they then served briefly with the post war Italian Air Force (AMI). For extensive wartime G.12T services and routes 1942 - 1945 see G.12 history.rtf in common folder.

From July 1942 605 Squadron of 148 Group also began to replace its Savoia Marchetti S.73s with Fiat G.12Ts. By November 1942 Italian forces had retreated so far that the African air bridge was once again being flown from Sicily to Tripoli. 605 Sq were operating the other major air bridge from Rome (LIRA) through Bucharest (LRBS), and Odessa (UKOO and use only 25/07 grass), to Stalino (UKCC) where the Regia Aeronautica was now engaged in the Eastern front Donets'k campaign. G.12s gradually adopted the overall dark green camouflage for operation at wave top height over the sea as radar coverage from Malta improved and those operating from Sicily to Tripoli increasingly also had to hug the African coast from Tunis all the way to Tripoli. Supply flights to Africa increasingly operated at night, but were vulnerable to interception by Mosquito night fighters in good weather. Skin by Manuele Villa, September 2009.
