Aconit was a unique frigate built for the French Navy during the Cold War, in commission from 1973 until 1997.

She was named after the corvette Aconit which fought in the Free French Naval Forces during World War II.

The Type C65 corvette was built to counter the improved performance of submarines in the 1960s, and was designed around two recently developed systems: the DUBV43 towed active sonar, and the Malafon anti-submarine missile.

The lack of facilities for landing helicopters was considered a significant drawback, and she was the last major warship built in France without them.

In 1984–85 she underwent a Indisponibilité pour Entretien et Réparations ("Unavailability for Maintenance and Repairs") during which the 305 mm anti-submarine mortar was replaced by eight Exocet MM40 missiles, and the DRBV-13 radar in the radome upgraded to the DRBV-15A.
