US Customs and Border Protection ordered its twelfth P-3 Orion Mid Lift Update, or MLU, kit on 26 May 2011. CBP has a fleet of sixteen P-3s based at Corpus Christi, Texas, and Jacksonville, Florida, that are flown on a variety of missions, primarily counternarcotics interdiction. Five P-3 operators – Norway, CBP, US Navy, Canada, and Taiwan – have a total of seventy-one sets of news wings on order. The MLU kit, which includes new wings as well as other structural components, gives Orion operators more than twenty years of additional service life.
