HTMS Makut Rajakumarn (1973) since about 1998 has operated as a training ship. LOA 320′ / 97.5 m TDISP 1,900 tons built Yarrow shipbuilders, Glasgow UK.
Although we could not locate any photos of the HTMS Makut Rajakumarn, the Royal Malaysian Navy ship KD Rahmat, F-24 (1971-2004), now a museum ship, was also built at Yarrows, Glasgow, to a very similar design. Major differences would include the heavier gun armament, with Makut Rajakumarn having a second 4.5″ gun at the stern. Credit: Mjabb / CC BY-SA
