The navy will build its second offshore patrol vessel, this one to be armed with guided missiles, at an estimated cost of 5.5 billion baht.
Vice Adm Jumpol Lumpiganon, deputy chief-of-staff and spokesman for the Royal Thai Navy, said on Monday the first OPV the navy built was HTMS Krabi.
The second offshore patrol vessel would be developed from the design of the first OPV, which was based on a design by BAE Systems Ships Co of England, he said.
The navy had signed a contract to buy the vessel’s design and materials from Bangkok Dock Co, a state enterprise under the Defence Ministry. The Mahidol Naval Dockyard of the Naval Dockyard Department would build the vessel and the Naval Ordnance Department will be responsible for its weapons systems.
The navy had developed its vessel building capability from building its own coastal patrol craft to building the first OPV, Vice Adm Jumpol said. HTMS Krabi was officially delivered in 2013.
Of the 5.5-billion-baht budgeted cost of the second OPV, 2.8 billion baht was for the vessel design, materials, tests, training, technology transfer, insurance and transport, and 2.7 billion baht for operating systems, weapons and project management.
The second OPV would cost more than the first, which came in at 2.93 billion baht, because in addition to main and secondary guns, it would also be equipped with a Harpoon anti-ship missile system, Vice Adm Jumpol said.

According to TAF
RTN spokesperson give some more detail about the second OPV project.
Aside from the BAE Systems’ enhanced design, the ship has helipad capable to accommodate the 11.5-ton helicopter or S-70B in RTN. RGM-84 Harpoon will be installed on board the ship and most of electronic systems are from Thales.
The project value is 5,482,930,000 Baht in which 2,832,930,000 Baht is the construction cost and another 2,650,000,000 Baht is for the weapon systems procurement. The timeframe will be from 2016-2018.
Thales reveals configuration of the RTN’s new OPV and proposed Pattani-class upgraded plan.
Royal Thai Navy is on the preparation process of building its new OPV, the second of the Krabi class, and they still choosing Thales Nederland as lead system and combat system integrator. The second ship will have a higher capability. Thales also proposed the upgrade plan for the Pattani-class that, if implemented, will bring the capability to the standard of what it is on Krabi class.
TACTICOS still a combat suite for the yet-to-be name OPV. 4 MOC Mk.3 console station will be installed along with two large collaboration wall displaying the situation picture. The air-surface surveillance radar will be the rotating 2D dual C/X-band TWT Variant radar along with rotating 2D X-band FMCW LPI solid-state Scout surface-helicopter control radar. Mk X(A) TSB2525 and STIR 1.2 EO Mk 2 is the main fire control. R-ESM capability rely on Vigile Mk 2. L3 Wescam MX-10MS optronic surveillance system and Terma SKWS C-Guard, X-Band and S-Band Sperry Marine Vision Master radar, Furuno ARPA radar will also be installed.
The ADS-B and AIS are also believed to be install on board.
Main gun will be Oto Melara 76/62 compact stealth shield and two MSI-DSL/ATK 30 mm DS30MR Mk.44. There are also an preparation for the anti-ship missile to be installed. RTN is looking at the RGM-84D Harpoon, but if there is any export ban RTN will shift to C-802A instead. But ThaiArmedForce.com believe that the Harpoon deal, if it is exist, will go through consider United States just approve the additional sale of RIM-162B ESSM to the RTN. The two Terma DL-12T will make this ship the first RTN ship that capable of avoiding the anti-ship attack.
Thales also providing the FICS integrated communication system and FOCON IP phone. Network centric mission will go through Thales Link Y Mk.2 that enable the ship to share information with allied force. Thales also integrating the Link RTN developed by Avia Satcom/Rohde & Schwarz. SATCOM will be using Cobham Sailor and underwater communication will be using Ocean Technology Systems Aquacom to communicate with diver. The LRAD also be installed for law enforcement mission.
Imtech Marine UniMACS 3000 series integrated bridge system will handle all bridge work. TACAN will be also installed. ThaiArmedForce.com’s opinion is this the indication that the new OPV will have an on-board 7 tons helicopter.
Another plan that Thales proposed to RTN is the Pattani-class OPV upgrade plan. Over specification will be On 17 September, Royal Thai Navy signed the contract with Bangkok Dock and Italthai Marine for drawing, materials, and associated equipment and services to be used in the construction of its new offshore patrol vessel (OPV)
2D dual C/X-band TWT Variant radar
2D dual C/X-band TWT Variant radar
The 3-in-one Variant radar, offers surveillance and target indication. Its principal role is as an automatic, fast reaction time radar sensor, supplying targeting data to weapon systems. Automatic target detection and tracking in 2D plus radial speed is supplied for both air and surface targets simultaneously. For surface targets, it offers 3 gunfire channels.
Variant includes a dual-band radar, utilising both the I- and G-bands (X&C-band). Fully coherent, Variant provides pulse-doppler operation for optimal clutter suppression and air target detection without disturbance by multi-path (or lobbing) effects thanks to the dual-frequency. Outstanding ECM facilities are provided by the ability to operate over two frequency bands, an octave apart, and the third part of Variant, an integral Low Probability of Intercept (LPI) radar. This LPI radar (see also entry: Scout) can be used alone, thus providing Variant the unusual ability to operate in a mode that is almost undetectable to external ESM.
Variant’s low power consumption, lightweight construction and compact design, make the system well suited for use on fast patrol boats and OPVs. For larger ships that need helicopter/UAV guidance, it’s the radar of choice, due to it’s extreme short minimum range. Source thales7seas.com

SCOUT Mk2 Thales Naval Nederland
2D X-band FMCW LPI solid-state Scout surface-helicopter control radar
SCOUT Mk2 Thales Naval Nederland, a Low Probability of Intercept (LPI) short-to-medium range surface surveillance and tactical navigation radar. Scout can be operated as a stand-alone mobile system for flexible responsiveness. Additionally, the system can be operated remotely (radio or line connection). It is an all-weather fully solid-state system of high reliability operating in X-band radar featuring Frequency Modulation Continuous Wave (FMCW) and therefore has an extremely low output power which makes the system ideal for cover operations in hostile environments where radar silence is required and thus its transmissions cannot be detected by ESM systems or radar warning receivers. SCOUT Mk2 outstandingly detects targets in adverse sea clutter conditions, thanks to its very small range cell size. The system is also very suitable for coastal surveillance. The range of the radar exceeds the 44km. Source navalanalyses.blogspot.com
STING-EO Mk2 weapon control system
STIR 1.2 EO Mk 2 is the main fire control. R-ESM capability rely on Vigile Mk 2. L3 Wescam MX-10MS optronic surveillance system and Terma SKWS C-Guard (Example May not be exact model)
STING-EO Mk2, Thales’s lightweight dual band (I and K) weapon control system, supports gun fire control, performs kill assessment and makes a valuable contribution to classification and identification of threats. In addition, the system can be used as a surveillance sensor, even under radar silence conditions.
The three data sources (I, K, EO) provide high redundancy, performance and ECCM resistance. STING EO Mk2 incorporates the latest solid-state I-band and K-band radars transmitters (low life cycle cost and high operational availability) and a new generation of electro-optical components (especially a third generation focal plane array infrared camera).
For operation in the littoral environment, STING EO Mk2 offers a list of benefits, such as: superior stealth target detection in strong (land) clutter, higher resistance against more stressing jamming scenarios and an extended EO capability for target identification and observation. Source THALES
