Design and construction

In 1969, Thailand ordered from the United States a single small PF 103-class frigate, of which four examples, the Bayandor class, had been built for Iran in the 1960s, with a second example being ordered in 1971. For procurement purposes, they were allocated the US Navy hull numbers PF 107 and PF 108.[2]

As built, single 3 inch/50 calibre Mk 34 automatic anti-aircraft guns were mounted fore and aft,[2] each capable of firing 6.8 kg (15 lb) shells to a range of 13,400 m (14,600 yd) at a rate of 45 rounds per minute,[3] backed up by a twin Bofors 40mm/L60 mount. Two triple Mark 32 torpedo tubes for anti-submarine torpedoes and a Hedgehog anti-submarine mortar comprised the ships' anti-submarine armament.[2] AN/SPS-6 air-search radar and SQS-17 sonar comprised the ships' sensor suite.[2]

Operational history

The first ship, Tapi, was commissioned on 19 November 1971, with the second ship, Khirirat, following on 10 August 1974.[1] Both ships were modernised during the 1980s, with the US 3-inch guns being replaced by a rapid fire OTO Melara 76 mm gun forward, and a Bofors 40mm/70 gun aft, with two single 20 mm cannon replaced the existing twin Bofors mount. The obsolete Hedgehog was removed, and the ships were fitted with new radar and sonar systems.[2][1]

As of 2002, they were used for patrolling Thailand's Exclusive economic zone.[1]
