Two F-27s entered service in 1978 for transport duties before being transferred to Air Benin. Also during the same era, two AN-26s were acquired. In late 1985, two Dornier Do-28s entered service to replace the C-47s. A single DHC-6 Twin Otter was acquired in 1989.
As of 2012, the navy had approximately 200 personnel. It operates two ex-Chinese patrol boats, which are designated the Matelot Brice Kpomasse class.
