Nigeria ordered two P18Ns from CSOC in April 2012 for US$42 million each. The first was slated to be completed in China, with the final 50–70% of the second being completed at the Nigerian Naval Shipyard in Port Harcourt; CSOC was contracted to upgrade the shipyard to facilitate this.
NNS CENTENARY (F91), the first P18N, was built at the Wuchang Shipyard in Wuhan. It was launched in January 2014 and completed trials in October 2014. CENTENARY left China in December 2014 and arrived in Lagos, Nigeria in February 2015; it was commissioned the same month.[ Delivery was originally expected in mid-2014.
The second OPV, NNS UNITY (F92), was reported in February 2015 to be undergoing outfitting at Wuchang, and was expected to be delivered in 2015. Nigeria had originally expected to receive it in mid-2014 for completion at Port Harcourt. The ship was delivered on 4 November 2016 to the Nigerian Navy in Lagos. NNS UNITY was commissioned on 15 December 2016. In January 2017 the vessel was deployed to The Gambia in a "show of strength" as part of an ECOWAS sponsored intervention in the 2016–17 Gambian constitutional crisis.[
