HTMS Chao Phraya (FFG-455) (Thai: เรือหลวงเจ้าพระยา) is the lead ship of her class of frigates for the Royal Thai Navy, a variant of the Chinese-built Type 053H2 frigate.
Chao Phraya has a length of 103.2 m (339 ft), a beam of 11.3 m (37 ft), a draught of 3.1 m (10 ft) and displacement of 1,676 long tons (1,703 t) standard and 1,924 long tons (1,955 t) at full load. The ship has two shafts and powered with four MTU 20V1163 TB83 diesel engines with 29,440 shp (21,950 kW). The ship has a range of 3,500 nautical miles (6,500 km) while cruising at 18 knots (33 km/h) and top speed of 30 knots (56 km/h). Chao Phraya has a complement of 168 personnel, including 22 officers.[1]
As a Type 053HT frigate, the ship are armed with two 100 mm/56 Type 79 twin-barreled guns and four 37 mm Type 76 twin-barreled guns. For anti-submarine warfare, the ship is equipped with two Type 86 anti-submarine rocket launchers and two BMB depth charge racks. For surface warfare, Chao Phraya is equipped with eight C-801 anti-ship missile launchers.[1]
In August 2020, The Royal Thai Navy planned to modernize the ships Chao Phraya and Bangpakong to have similar capabilities to a modern offshore patrol vessel. The planned upgrade includes replacing the 100 mm guns with 76/62 automatic guns and all four 37 mm guns with a rapid-fire 30 mm autocannon, along with new combat management systems and surveillance systems.[2]
