Royal Thai Navy set to buy ESSMs for upgraded frigates

The Royal Thai Navy has signed a letter of offer and acceptance (LOA) with the US government to purchase nine Evolved SeaSparrow Missile (ESSM) systems for its two Naresuan frigates currently undergoing overhauls and upgrades.

The LOA increases the total ESSM user community to 13 nations.

The Royal Thai ESSMs will be fired from an MK 41 eight-cell vertical launch system using an MK 25 Quad Pack canister. This capability will allow for up to 32 ESSMs on each ship.
