Sierra-class corvette

The Sierra-class corvettes are corvettes of the Mexican Navy 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 Sierra commissioned by the Mexican Navy in 1998. One ship, ARM Benito Juárez, was sunk as a target ship in 2007 after being wrecked by fire in 2003. The other three vessels remain in service.
