SALINA CRUZ, Mex. -- Damen Shipyards has delivered the Combat Systems Module for the Patrulla Oceánica de Largo Alcance (POLA) frigate to Mexico. The Combat Systems Module contains the command bridge for the vessel. It is the final of two modules built by Damen in the Netherlands. The other four modules are being built by SEMAR at the ASTIMAR 20 shipyard in Salina Cruz, Oaxaca.
Damen began construction of the POLA, which is based on its Sigma 10514 vessel, in August 2017. As with the previous Sigma vessels Damen built for the Indonesian Navy, the vessel for Mexico is being constructed modularly, with shipbuilding activities taking place in both the Netherlands and Mexico. Two of the six modules were constructed at DSNS’ location in Vlissingen, whilst the remaining four will be built at a Mexican Shipyard. Upon conclusion, the six modules will be integrated in Mexico. This way Damen contributes to the development of the shipbuilding capabilities of the Mexican Naval Industry related to control, propulsion, and detection systems.
Although Mexico has discussed purchasing secondhand frigates from the U.S., no deal was every signed. Ultimately, Mexico decided to purchase a new vessel from Damen. A contract was signed in early 2017. The advantage is that it will enable government to support its internal industry and provide employment opportunities for Mexican workers.
The Sigma 10514 frigate is a little more than 105 meters long with a 14 meter beam and can accommodate 120 crew members. Powered by Combined Diesel or Electric (CODOE) 2x10,000 kW engines and 2x1,300 kW engines, the vessels can reach a maximum speed of 28 knots. Each vessel is equipped with a 76 mm gun, close in weapons system (CIWS), ship-to-ship missile launches, short range air defense weapons, torpedo launchers, chaff dispensers, and a full electronic complement including radar, electro-optical systems, a sonar, electronic countermeasures systems, and electronic support measures. Mexico got approval from the U.S. to acquire Evolved Sea Sparrow missiles for the vessel in August 2018.
