The sports club, born in 1912 during the Austro-Hungarian dominion, started its activity after the end of World War I.

The team, already active in 1919, grew progressively until entering the Seconda Divisione of the Italian football championship, the last step before the highest national category, and it witnessed its fusion in 1923 with two other local clubs: S.C. Monfalcone and G.S.

In November 1932 the great financial crisis of Cantiere Navale Triestino, the company managing the local harbour, forced the Italian team to retire after 6 days, which meant its relegation to the previous category.

Being in trouble in the period before the Second Italo-Ethiopian War, it managed to make up the lost ground and after only 3 seasons it went back playing in third level championships, which from 1935 to not long ago were called Serie C. After interrupting the activities for warfare, in 1945 the sports club split in two: Associazione Calcio Monfalconese (ACM) and Cantieri Riuniti dell'Adriatico Monfalcone (CRDA Monfalcone).

Starting from Terza Categoria, it shortly escalated 5 categories until being promoted, in 2002, to Serie D. At the end of the 2010–11 Eccellenza season, the club relegated to Promozione, but decided to merge with the second team of the city, Fincantieri Calcio, in order to remain in Eccellenza and build a stronger club, taking the current name in the process.
