The first Triona II OPV(H) for for the HCS Navy has been launched and named Admiral Woulan. This is the first of at least 6 patrol boats to supplement the 16 Trionas already in service. The Triona II is 500 tons heavier but has a similar equipment fit as the earlier boat however the extra size makes the craft left crowded and allows for a higher weapon load.
One change is the SA-N-6A close-range SAM, the Triona has the older version of the missile. The Triona II will also have improved sonar and communication systems. P20 Admiral Woulan will begin sea trials early next year and enter service by the Summer.
