HTMS Chakri Naruebet (911) is the flagship of the Royal Thai Navy (RTN), and Thailand's first and only aircraft carrier, although the RTN refers to her as an "Offshore Patrol Helicopter Carrier".

Based on the Spanish Navy's Príncipe de Asturias design and constructed by Spanish shipbuilder Bazán, Chakri Naruebet was ordered in 1992, laid down in 1994, launched in 1996, and commissioned into the RTN in 1997. The ship is the smallest functioning aircraft carrier in the world.

The aircraft carrier was designed to operate an air group of V/STOL fighter aircraft and helicopters, and is fitted with an aircraft ski-jump. Initial intentions were to operate a mixed air group of ex-Spanish AV-8S Matador Harrier V/STOL aircraft and Sikorsky SH-60 Seahawk helicopters.

Chakri Naruebet has been deployed on several disaster relief operations, including in the aftermath of the 2004 Indian Ocean earthquake and tsunami, and in response to separate flooding incidents in late-2010 and early-2011.

Chakri Naruebet while still operating with Harriers was the smallest aircraft carrier with a fixed wing air group in operation in the world. She displaces 11,486 tons at full load.

The carrier is 164.1 metres (538 ft) long between perpendiculars, and 182.65 metres (599.2 ft) overall. 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).

The warship has a ship's company of 62 officers, 393 sailors, and 146 aircrew. Up to 675 additional personnel can be transported, usually from the Royal Thai Marine Corps.

Chakri Naruebet is propelled by a combined diesel or gas (CODOG) system. 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).

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.

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).
