The Mexican Secretariat of Navy (SEMAR) said the OPV is ARM Chiapas (PO 165) and the logistics ship is ARM Isla Maria Madre (BAL 11). Constructed at the Naval Shipyard (ASTIMAR) N°20 in Salina Cruz, Oaxaca, Chiapas is the first of four OPVs that were ordered as part of the SEMAR 2013-2018 plan. The second, ARM Hidalgo (PO 166), has already been launched and is expected to be commissioned in 2017, while construction of the third ship has already started in Salina Cruz. < snipped > The logistics ship Isla Maria Madre is based on the Damen Fast Crew Supplier 5009 design and built by ASTIMAR N°6 in Guaymas, Sonora. It was constructed for the specific purpose of providing transport capabilities for the prison complex on the Islas Maria archipelago off Mexico's Pacific Coast.
