The club was founded in 1964 under the name Metalul Mangalia and was financially sustained by the
Mangalia Shipyard, achieving promotion to the
Dobrogea Regional Championship at the end of the 1965–66 season. Metalul performed solidly in the Regional Championship, finishing 4th in the
1966–67 season and 7th in the
1967–68 season, gradually establishing itself as a competitive side. In the
1968–69 season, Metalul won the first edition of the
Constanța County Championship following the territorial reorganization of the country but failed to secure promotion to the
third division, losing to Laromet București, the winner of the
București Municipal Championship (0–0 in Mangalia and 0–2 in București). Metalul promoted to
Divizia C at the end of the
1979–80 season, winning the County Championship and the promotion play-off against Victoria Râmnicu Sărat, the
Buzău County Championship winner, 8–2 on aggregate (5–2 at home and 3–0 away). In the third division, Metalul first competed in Series IV, finishing 4th in the
1980–81 season, 10th in the
1981–82 season, and 8th in the
1982–83 season. In the
1983–84 season, Metalul won Series III, earning promotion to
Divizia B for the first time in its history. The team, led by Vasile Mihu as head coach and Dan Dima as assistant coach, was composed of: Dumitru, Jianu, Vodă, Voicu, Greavu, Stoica, Toader, Negure, Sail, Gîrdea, Ali, George Turcu, Irimet, Drăghiceanu, Belu, Stamate, Dedeanu, Căciularu, Carastoian, Isaic, and Simion. Metalul Mangalia struggled in the
second division, finishing 16th in Series I, just two points short of safety, and being relegated after
only one season. The following two seasons in Series IV of the third division saw the team fighting to avoid relegation, finishing 12th in the
1985–86 season and improving in the
1986–87 season, ranking 4th. The club was immediately relegated back to the third division in the
following season, finishing last after a disappointing campaign, despite Ion Carastoian emerging as the top scorer of Series II with 18 goals. Following the relegation, Metalul merged with Callatis Mangalia—a team from the
county championship named after the
historical Greek name of the city—and adopted its name. In the
2011–12 season,
Marin Barbu was appointed as head coach, but after disappointing results in the first six rounds, where the team earned only 3 points, he was dismissed.
Cristian Șchiopu briefly served as interim coach before
Mugurel Cornățeanu took over in October, guiding the team to a 9th-place finish in Series I of
Divizia B. However, Callatis faced significant financial difficulties and withdrew from the competition just four days before the start of the
following season. Reorganized in
Liga IV – Constanța County, the team led by
Mugurel Cornățeanu, finished 1st in the
2012–13 season and earned promotion to
Liga III by defeating Voința Cocora 9–1, the
Liga IV – Ialomița County winner. In the third division, Callatis competed in Series II, finishing 8th in the first stage and 9th overall in the
2013–14 season, and 10th in the
2014–15 season. However, due to ongoing financial problems, the team withdrew from Liga III in the summer of 2015. ==Honours==
