Navantia announced on 22 August 2025 that it has signed a new contract with the Royal Thai Navy (RTN) to modernise two Pattani-class offshore patrol vessels (OPVs).
Navantia will carry out the engineering, supply and integration of a new combat system, the core of which is the CATIZ combat management system developed by Navantia Sistemas, as well as other advanced systems from other manufacturers. Additionally, Navantia will provide lifecycle support documentation and ensure training in the operation and maintenance of the system.
This is the second contract Navantia has signed with the RTN in 2025, having been awarded a contract to modernise the RTN landing platform dock (LPD) HTMS Chang in April. Navantia’s predecessor company, Empresa Nacional Bazán, also built the RTN’s flagship: the light aircraft carrier HTMS Chakri Naruebet.
