Trat-class torpedo boat

The Trad class was a class of nine torpedo boats built for the Royal Thai Navy in the 1930s by the Italian shipbuilder Cantieri Riuniti dell'Adriatico. They entered service between 1935 and 1938. Two of the ships were sunk (and a third badly damaged) by French warships at the Battle of Ko Chang in 1941, but the remaining seven ships had long careers, remaining in service until the 1970s.
