The Oaxaca class are offshore patrol vessels, constructed and designed by and for the Mexican Navy. The class is named after the Mexican state of Oaxaca. The Mexican Navy has requested seven of these ships with four already in service, three in construction, which were disclosed on June 1[year missing] on the Navy anniversary, with the name PO-163 Independencia, which is to celebrate the 200th anniversary of the Independence of Mexico. Also, another ship PO-164, named Revolucion, is in the process of raising the Mexican flag in a couple of months. Two more to be constructed in Navy's Naval Shipyards.


The vessels are 282 feet 2 inches (86.0 m) long and have a draft of 11 feet 8 inches (3.6 m), and a beam of 34 feet 4 inches (10.5 m). They displace 1,680 short tons (1,524.1 t).[1]

Primary armament is a single OTO Melara 76-millimetre (3 in) naval gun. They also mount a pair of OTO Melara remote controlled naval turret Mod. 517 with M2 12.7 mm (0.50 in) machine guns, one on each side. At the rear on helicopter hangar is a single OTO Melara 30 mm (1.2 in) cannon. The class has a helipad on the afterdeck with handling capabilities for a variety of helicopters, such as the Panther, Fennec, or the Bolkow B-105 Super-5. It has a top speed of over 20 knots (37 km/h; 23 mph) and a cruising speed of 14 knots (26 km/h; 16 mph). The ships carry a complement of 77, and have provisions to carry a group of 39 special forces and/or marines for a variety of missions.

The Oaxaca class also carries a Patrol Interceptor in its well deck.

For the 2008 fiscal year, the Mexican Congress approved $68 million in funds to build two more Oaxaca-class ships, and pledged an additional $40 million in 2009.


The objectives for the Oaxaca class are oceanic surveillance, search and rescue operations, support for the civilian population in case of disasters, maritime support and to act as a deterrence against hostile ships and aircraft in low-medium intensity conflicts.
