The ship arrived the Calabar waters at 12 noon complete with senior naval personnel, Cameroonian journalists and civilian dignitaries.
The Commander of Information at the Eastern Naval Command, Commander Abdulkadir said the Nigerian Navy authorities were yet to be formally briefed about the mission of the flag ship.
The Ambassador of Cameroon in Nigeria was escorted into the ship where he received salutes from both Nigerian Navy and the Cameroon Navy personnel before he shook hands with his compatriot.
Abdulkadir however said that they would pay courtesy call on the Flag Officer Commanding Eastern Naval Command Rear Admiral James Oluwole during which time they would disclose their mission in Nigeria.
The Ambassador of Cameroon did not talk to journalists, but the ship is believed to be on a friendly visit.
