In 2017, Carmen București was refounded and introduced in the Liga IV, the fourth tier of the Romanian football league system.

[2] Carmen, which originally took the name of its owner, Ionel Mociorniță, started to play in Liga III but when Liga I was reorganised after the war gained a place in the top league, as the team incorporated few of the best-known players at the time.

During the break of the 1946–47 season, at which end Carmen was runner-up, the team was ordered by the Government to play a friendly game against FC Dinamo Tbilisi, a Soviet team, after being also advised to "lose", as the game was supposed to be communist propaganda.

The situation was not forgotten by the authorities and in the summer of 1947, just one week before the start of the 1947–48 season, the team was refused its place in Liga I and immediately dissolved.

After a weak first part of the championship and due to historical debts of the club, Onosă withdrew and took the control of Liga III side Dacia Unirea Brăila instead.
