HTMS Chakri Naruebet (Thai จักรีนฤเบศร, meaning "In honour of the Chakri Dynasty"[1]) is the flagship of the Royal Thai Navy (RTN), and Thailand's first and only aircraft carrier. Based on the Spanish Navy's Principe de Asturias-class design and constructed by Spanish shipbuilder Bazán, Chakri Naruebet was ordered in 1992, launched in 1996, and commissioned into the RTN in 1997.
The carrier is equipped with an air group of V/STOL aircraft and helicopters, and was intended for patrols and force projection in Thai waters, disaster relief, and amphibious warfare support. However, a lack of funding brought on by the 1997 Asian Financial Crisis means that the carrier has spent much of her career docked at the Sattahip naval base. The carrier has been deployed on several disaster relief operations, although her other departures from port consist primarily of a single training day per month, and transportation of the Royal Family of Thailand, leading to claims that the ship is merely an oversized royal yacht.[1][3] In recent years, the carrier was assigned flood relief and civilian evacuation roles, as in the recent 2010 and 2011 Thai floods.[4]
Design
When Typhoon Gay hit Thailand in 1989, the Royal Thai Navy, as the main unit responsible for search and rescue missions, found that its ships and aircraft were unable to withstand the rough weather at sea.[5] Moreover, the Royal Thai Navy needed a new, high-technology ship to modernize its fleet.[5]
The original plan was to acquire a 7,800 ton vessel from Bremer Vulcan, but the Thai government cancelled the contract on 22 July 1991.[2] A new contract for a larger warship to be constructed at Bazán's shipyard in Ferrol, Spain, and was signed by the Thai and Spanish governments on 27 March 1992.[2] The proposed vessel was based on the design of the Spanish Navy aircraft carrier Principe de Asturias, which in turn was based on the United States Navy's Sea Control Ship concept.[6][3]
Chakri Naruebet is the smallest aircraft carrier in operation in the world. She displaces 11,486 tons at full load.[1] The carrier is 164.1 metres (538 ft) long between perpendiculars, and 182.65 metres (599.2 ft) overall.[1] She is 22.5 metres (74 ft) wide at the waterline, with a maximum beam of 30.5 metres (100 ft), and a draught of 6.12 metres (20.1 ft).[1] The warship has a ship's company of 62 officers, 393 sailors, and 146 aircrew.[1] Up to 675 personnel can be transported; commonly soldiers of the Royal Thai Marine Corps.[1][7]
Chakri Naruebet is propelled by a combined diesel or gas (CODOG) system.[1] Each of the two, five-bladed propellers is connected to a Bazán-MTU 16V1163 TB83 diesel engine (providing 5,600 brake horsepower (4,200 kW), used for cruising speed), and a General Electric LM2500 gas turbine (providing 22,125 shaft horsepower (16,499 kW), used to reach top speed for short periods).[1] Chakri Naruebet has a maximum speed of 25.5 knots (47.2 km/h; 29.3 mph), although she can only reach 17.2 knots (31.9 km/h; 19.8 mph) with the diesels alone.[1] She has a maximum range of 10,000 nautical miles (19,000 km; 12,000 mi) with a constant speed of 12 knots (22 km/h; 14 mph), and 7,150 nautical miles (13,240 km; 8,230 mi) at 16.5 knots (30.6 km/h; 19.0 mph).[1]
Armament and aircraft
Chakri Naruebet is fitted with two 0.5-inch machine guns, and three Matra Sadral sextuple surface-to-air missile launchers firing Mistral missiles.[2][7] The missile launchers were installed in 2001.[2] The vessel is also fitted for but not with an 8-cell Mark 41 Vertical launch system for Sea Sparrow missiles, and four Phalanx close-in weapon systems.[3]
The carrier's standard air group consists of six to eight AV-8S Matador V/STOL aircraft (a first generation export version of the Harrier acquired secondhand from the Spanish Navy) and four to six S-70B Seahawk helicopters.[1][6][7] By 1999, only one Matador was operable.[8] Replacement aircraft have been considered including the BAE Sea Harrier formerly operated by the Royal Navy.[citation needed] Chakri Naruebet is also capable of carrying up to fourteen additional helicopters; a mix of Sikorsky Sea King, Sikorsky S-76, and CH-47 Chinook.[1] There is only enough hangar space for ten aircraft.[2][7]
The flight deck measures 174.6 by 27.5 metres (573 by 90 ft).[2] A 12° ski-jump is fitted to assist the Matadors in taking off.[2] There are two aircraft lifts, each capable of lifting 20 tons.[2]
Sensors and countermeasures
The sensor suite of Chakri Narebet consists of a Hughes SPS-52C air search radar operating on the E/F band, and two Kelvin-Hughes 1007 navigational radars.[2] There are provisions to install an SPS-64 surface search radar and a hull-mounted sonar, but neither has been fitted as of 2008.[2][7] Fire control facilities are also yet to be fitted.[2]
The carrier is equipped with four SBROC decoy launchers,[7] and an SLQ-25 towed decoy.[citation needed]
Construction
Work on the Thai carrier commenced in October 1993, although it was not until 12 July 1994 that the hull was laid down.[2][3] Chakri Naruebet was launched on 20 January 1996[3] by Queen Sirikit.
Sea trials were conducted from October 1996 to January 1997, the latter part of which was in coordination with the Spanish Navy.[2][3] This was followed by aviation trials at Rota, Spain.[2] The carrier was handed over on 27 March 1997, when she was commissioned into the RTN.[1][2] She arrived in Thai waters at the start of August 1997, and formally entered service on 10 August.[3]
Chakri Naruebet cost US$336 million to build.[8]
Role and operational history
Chakri Naruebet is the first aircraft carrier to be operated by a Southeast Asian nation.[3] She is assigned to the Third Naval Area Command, and her intended duties include operational support of the RTN's amphibious warfare forces, patrols and force projection around Thailand's coastline and economic exclusion zone, disaster relief and humanitarian missions, and search-and-rescue operations.[1][2][6][3][8] However, at the time the carrier entered service, the 1997 Asian Financial Crisis prevented the necessary funding to operate the ship from being available.[3][8] The limited defensive armament compounded the problem; consequently, Chakri Naruebet is usually only operational for a single day per month for training, with the rest of the time spent alongside as a "part-time tourist attraction".[1][3][8] The ship rarely leaves the proximity of the Sattahip naval base, and when she does, it is usually to transport and host the Royal Family of Thailand.[1][3] Naval commentators consider Chakri Naruebet to be less an aircraft carrier and more the world's most expensive royal yacht, while the Thai media have nicknamed the ship "Thai-tanic", and consider her to be a white elephant.[3][8]
Between 4 and 7 November 1997, Chakri Naruebet participated in disaster relief operations following the passage of Tropical Storm Linda across the Gulf of Thailand and the Kra Isthmus.[9] The carrier's main task was to search for and assist any fishing vessels affected by the storm.[9]
Flooding in the Songkhla Province resulted in the carrier's mobilisation in late November 2000.[9] Chakri Naruebet was anchored at an island marina off Songkhla, and used as a base for helicopters and small boats transporting food, supplies, and wounded.[9]
In January 2003, anti-Thai riots were sparked in Phnom Penh by incorrect news reports of a claim by a Thai actress that the Angkor Wat temple complex belonged to Thailand, not Cambodia. Chakri Naruebet was sent to help with any evacuation of Thai citizens from Cambodia.[clarification needed][9]
Following an undersea earthquake in the Indian Ocean, tsunamis struck multiple regions around the Indian Ocean, including the Andaman Sea coast of Thailand. The personnel of Chakri Naruebet were part of a 760-strong response by the Thai military to the disaster.[9] This task force was involved in search-and-rescue around Phuket and the Phi Phi Islands, treatment of wounded and handling of dead, and repair work to schools and government facilities.[9]
During the August 2005 filming of Rescue Dawn, a dramatised biographical film of US Navy pilot Dieter Dengler and his capture during the Vietnam War, the flight deck of Chakri Naruebet was used to represent the carrier USS Ranger.[citation needed]
In 2010, it was involved in flood relief[10] and again in spring of 2011.[11] [12]
