Pattimura International Airport (IATA: AMQ, ICAO: WAPP), formerly known as Laha Airport, is an international airport serving Ambon, the capital and largest city of Maluku Province, Indonesia. The airport is the largest and busiest in the Maluku Islands. Located 38 kilometers (23.6 miles) west of Ambon’s city center, the airport is named after Thomas Matulessy (1783–1817), an Indonesian national hero from Maluku who is more widely known as Pattimura. He led the resistance against Dutch colonial forces in the 19th century. Pattimura Airport serves as the primary gateway to Ambon and the Maluku Islands, offering regular flights to major Indonesian cities such as Jakarta, Surabaya, and Makassar, as well as regional destinations within Maluku. The airport previously operated international flights to Darwin, Australia, but these services were later discontinued. Its international status was briefly revoked in 2024, before being reinstated the following year.

In addition to its role as a commercial airport, Pattimura Airport also hosts Pattimura Air Force Base, a Type B installation of the Indonesian Air Force. The airbase is situated southeast of the passenger terminal, across the runway.

The airport was originally established by the Dutch colonial government in 1939 and was then known as Laha Airfield. It served as a military airbase for the Royal Netherlands East Indies Army Air Force (ML-KNIL). Although located in a remote region, the Dutch recognized the strategic importance of the airfield as a key defensive position in anticipation of a potential Japanese invasion of the Dutch East Indies during the Pacific Theatre in World War II. In 1941, they reinforced the airfield by deploying additional Royal Netherlands East Indies Army troops from Java. The Australian government also acknowledged the airfield’s strategic significance, as its capture would allow the Japanese to launch air raids on the Australian mainland. As a result, Australia dispatched forces to assist in the airbase’s defense. Prior to the Japanese landing at Ambon in 1942, Laha Airfield was defended by two companies of the Australian 2/21st Battalion alongside approximately 300 Dutch troops. The defensive force was supported by Dutch artillery, which included four 75 mm field guns, four 37 mm anti-tank guns, four 75 mm anti-aircraft guns, four 40 mm anti-aircraft guns, as well as an anti-aircraft machine gun platoon and battery. The Allies had limited air resources to allocate. The ML-KNIL deployed No. 2 Flight, Group IV (2-Vl. G.IV) from Java to Laha, but of the four Brewster F2A Buffalo aircraft originally assigned, two were lost in crashes en route to Ambon. The Royal Australian Air Force (RAAF) contributed two flights comprising a total of 12 Lockheed Hudson Mk II light bombers from No. 13 and No. 2 Squadrons. One flight was stationed at Laha, while the other was deployed to Namlea on the neighboring island of Buru.

Japanese troops landed on Ambon on 30 January 1942, and the first ground assault on Laha Airfield took place the next day. An Australian platoon positioned northeast of the airfield came under attack from a larger Japanese force but successfully repelled the assault. Meanwhile, Japanese reinforcements arrived, and a sustained offensive against the Allied defenders began, involving naval artillery, dive bombers, fighter aircraft, and infantry probing attacks. A Japanese night assault through tall grass near the beach—between two Allied positions—was also driven back by an Australian platoon. However, at dawn on 2 February, the Japanese launched a major offensive. By 10:00 a.m., only around 150 Australian troops and several KNIL personnel remained combat-effective at Laha. They surrendered shortly thereafter.

After the capture of Laha Airfield, Japanese forces executed more than 300 Australian and Dutch prisoners of war who had surrendered there. Personnel from the Imperial Japanese Navy selected the prisoners at random and carried out summary executions in four separate massacres around the airfield. The victims were bayoneted, clubbed to death, or beheaded—none survived. Following the war, 93 Japanese personnel were tried by an Australian military tribunal in Ambon for war crimes related to the Laha massacres. Several were convicted and executed.

The base was extensively used by Japanese forces throughout the occupation to support their military operations. Aircraft stationed at Ambon participated in the major air raids on Darwin, Australia, on 19 February 1942.

After Indonesia declared independence, the airport was taken over by the Indonesian Air Force and continued to function as a military airbase. During the Permesta rebellion in the 1950s, the airbase was targeted and bombed multiple times by the Permesta Air Force (AUREV), which received covert support from the United States. Several Indonesian Air Force aircraft were damaged during the bombing raids. Among those involved in the attacks was Allen Lawrence Pope, an American CIA pilot who flew missions for AUREV. On 18 May 1958, Pope’s Douglas A-26 Invader was shot down over Ambon by an Indonesian Air Force P-51 Mustang after he bombed the airfield. His capture and the discovery of American involvement in the rebellion marked a turning point in the conflict.

In 1 August 1962, when the Indonesian government created a unit responsible for overseeing the civil aviation maintenance and operations of airports for civilian air transport. Despite this, the airport remained under the control of the Indonesian Air Force. In 1975, following a Joint Decree by the Minister of Defense, the Armed Forces Commander, the Minister of Transportation, and the Minister of Finance, the airport was officially designated as a civilian airfield and came under the full jurisdiction of the Department of Transportation. On 11 October 1995, the management of Pattimura Airport was transferred to Angkasa Pura I, a state-owned enterprise responsible for managing airports in central and eastern Indonesia, which is now known as InJourney Airports.
