Aradu (F89) (meaning "thunder" in Hausa) is a Nigerian frigate. She is the first of the MEKO 360 General Purpose frigates built by the German Blohm + Voss company of Hamburg.
The 125.6 m ship is the biggest in the Nigerian Navy. She is a multi-purpose frigate with capabilities for anti-air, anti-surface and anti-submarine warfare effectively, and participated in the 200th anniversary celebrations of the Battle of Trafalgar. The ship also possesses capability for naval fire support and electronic warfare. Additionally, she carries a ship-borne helicopter for anti-submarine warfare, search and rescue, and enhanced surveillance/detection.
The ship is unique in the adoption of the modular approach in the design of hull and the containerization of armaments. By the modular design concept, various sections of the hull of Aradu are built to specific measurements separately and then assembled at a shipyard. The advantage of this style of construction is that every section of the ship can be produced independent of the other sections. In case of damage, it is thus easier to replace the affected section of the ship separately and then fixing it back at a shipyard. This same flexibility is adopted in the armament of the ship. These are kept in containers and can be tested ashore independent of the various stage of construction. Once the hull is ready, the containerized armaments are then easily fitted into the hull the same procedure adopted in case of major repair or replacement.
