The Sierra-class oceanic patrol corvettes are intended mainly for interception of drug smugglers, Exclusive Economic Zone (EEZ) patrol, and countering terrorism. The class comprises four ships with the lead ship ARM (Armada de la Republica Mexicana/Mexican Republic Navy) Sierra (P-141) commissioned by the Mexican Navy in 2000.
Originally, Sierra class corvette project was designated Holzinger 2000 because it is a further development of Mexican Navy Holzinger-class ships introduced in the early 1990s. These ships represent modern shipbuilding with an aft flight deck and hangar for one MBB BO-105C helicopter, stealth features and one 57mm Mk2 naval gun in the fore deck to engage air and surface targets.| General characteristics | |
