P18N Offshore Patrol Vessels have a displacement of 1,700 tons, a length of 95 m, width of 12.2 m and beam of 3.5 m. It is powered by two MTU 20V 4000M diesel engines (I believe this is essentially the same engine as in the Webber class WPCs–Chuck). The maximum speed is 21 knots. The endurance of the vessel is 20 days at sea (range 3000 nautical miles at 14 knots) for a crew of 70 sailors.
The range and speed are certainly adequate for their purposes, but “nothing to write home about,” and the hangar is only suitable for UAVs, but it is actually better equipped in some ways than the proposed Cutter X with a 76mm gun and two 30mm. This probably contributes to the size of its 70 member crew.
Nigeria is modernizing their forces. The Nigerian Navy took over the former USCGC Chase in 2011, and they expect to get the Gallatin in 2015. Nigeria is the source of much of our imported oil, and they have an ongoing insurgency and a serious piracy problem.
If the helicopter on the model pictured above looks familiar, it is a Z-9, a Chinese license built version of the French helicopter that was the basis for the H-65. Chinese variants include both ASW and attack helicopter versions.
