Corvettes and Patrol Ships
Offshore Patrol Vessels
Oaxaca class LOA 282′ TDISP 1,700 tons (8 active, 2 building, service since 2003)
Durango Class LOA 268′ TDISP 1,400 tons (4 active, service since 2000)
Sierra Class LOA 246′ TDISP 1,350 tons (3, 2 active, service since 1998) multiple overall length measurements suggest this class longer than the 231′ in Jane’s Fighting Ships editions from the early 2000s. The Sierra class seems to have been designed with more radar signature-minimizing elements than earlier and later classes, though, like other Patrol Boats, a major role is drug interdiction patrols.
