Mexican Navy Ship Arrives in Puerto Vallarta to Reinforce Security Operations

As part of federal support efforts in the wake of the February 22 unrest, the Mexican Navy vessel ARM Usumacinta (A-412) arrived at the port of Puerto Vallarta on the afternoon of February 23.

The presence of the ship strengthens the federal security deployment in the region, where surveillance operations and interagency coordination continue following road blockades, vehicle fires, and attacks reported across the city and its metropolitan area.

The Usumacinta is one of the largest and most versatile ships in the fleet of the Armada de México. Classified as an amphibious assault and logistical support vessel — a Landing Ship Tank (LST) — it is designed to transport personnel, vehicles, and equipment, and to conduct landing and ground-support operations.

Originally built in the United States as the USS Frederick (LST-1184), the vessel served in the U.S. Navy from 1970 to 2002. Mexico later acquired it through the Security Assistance Program and incorporated it into its naval fleet in 2002.

Measuring more than 160 meters (approximately 525 feet) in length, the ship is capable of extended autonomous operations at sea. Beyond its military role, the Usumacinta has participated in humanitarian missions and disaster relief efforts, transporting aid and supplies during natural emergencies.

The vessel has also taken part in multinational exercises such as the RIMPAC and has served in training cruises for cadets of the Heroic Naval Military School.

Its arrival in Puerto Vallarta represents a strategic reinforcement of security measures as authorities from federal, state, and municipal levels continue coordinated efforts to fully restore stability and normalcy in the region.
