Holzinger-class patrol vessel

Holzinger-class patrol vessels are offshore patrol vessels in service with the Mexican Navy. They are a Mexican design, based on the Uribe class developed by the Spanish Naval Company Empresa Nacional Bazán in 1982. Holzinger-class patrol vessels have a smaller helicopter deck than the Uribe class and have main armaments (two twin US MK1 Bofors 40 mm AA mounts) at 'A' position. They are able to operate MBB Bo 105 helicopters on board.
