ESSM for Mexican Navy SIGMA 10514 POLA Surface Vessel.

The U.S. State Department has made a determination approving a possible Foreign Military Sale to Mexico of six Raytheon Evolved Seasparrow tactical missiles (ESSM) and two Evolved Seasparrow telemetry missiles for an estimated cost of $41 million. The missiles are intended for the Mexican Navy's first Sigma 10514 "POLA" surface vessel currently under construction.

The Government of Mexico has requested to buy six (6) Evolved Seasparrow tactical missiles (ESSM) and two (2) Evolved Seasparrow telemetry missiles. Also included are one (1) MK56 VLS launcher (8-cell), eight (8) MK30 canisters, eight (8) MK783 shipping containers, spare and repair parts, support and test equipment, publications and technical documentation, training, USG/Contractor technical and engineering support services, and technical assistance. The total estimated value is $41 million.

Mexico intends to use the weapons systems on its Sigma 10514 Class ship. The systems will provide enhanced capabilities in effective defense of critical sea lanes. The proposed sale of these systems and support services will increase the Mexican Navy's maritime partnership potential and align its capabilities with existing regional navies. Mexico has not purchased these systems previously. Mexico will have no difficulty integrating this equipment into its armed forces.

Mexico intends to use these defense articles and services to modernize its armed forces and expand its existing naval and maritime support of national security requirements.

The principal contractor will be Raytheon Missile Systems, Tucson, Arizona.

About ESSM
ESSM is a medium-range, all-weather, semi-active radar-guided missile used in surface-to-air and surface-to-surface roles. ESSM represents more than four decades of technology and design improvements by a 43-year international cooperative partnership composed of 12 nations, 10 of which employ ESSM (and FMS to 3 countries: Japan, UAE and Thailand).

As a tail-controlled missile, ESSM uses enhancements to its guidance system to take advantage of improved seeker sensitivity, increased propulsion and greater weapon accuracy. These features enable ESSM to arrive at the intercept point with more endgame speed and agility to counter the threat.

ESSM's capability bridges the gap between close-in air defense and local area defense systems. Its kinematics result in reduced time to target. It is a Multi-mission weapon system is effective against high-speed or low-velocity threats.

According to open sources, the RIM-162 Evolved SeaSparrow Missile (ESSM) has a range of about 27 nautical miles (50 Km) and a top speed of Mach 4+.

Damen Shipyards Group and the Mexican Navy, via the Directorate General of Shipbuilding, are currently working together to build the Long Range Ocean Patrol (POLA (from its initials in Spanish)).

POLA will be the Mexican version of the Damen SIGMA 10514, a proven design that has booked successful results internationally. POLA will be 107 metres in length, with a beam of 14 metres. It will be able to sail at speeds of up to 25+ knots and a capacity of more than 20 days at sea.

The flagging ceremony of the POLA is planned for November 2018. After this, a full integrated process of setting to work, commissioning, training, tests and trials will continue in 2019.

Characteristics of the POLA
• Length: 107 m
• Beam: 14 m
• Displacement: 2,570 tons
• Speed: 25+ knots
• Propulsion: CODOE
• Range: 20+ days
