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. Although considered to be the ultimate evolution of the T 47 class, performance did not live up to expectations, and the development of the propulsion system took much longer than expected. The lack of facilities for landing helicopters was considered a significant drawback, and she was the last major warship built in France without them. Eventually the C65 programme, in which five ships were planned, was cancelled.
