the Dutch, again under pressure of the United Nations, left in 1963. Several missions of Taiwan-based Lockheed U-2s from 35th Squadron flew over Maluku (Moluccas) and reported to Dutch military that there was a strong possibility that the Dutch would lose their air superiority over Papua if they continued the war. During Operation Trikora, the air force was deployed as follows: 7 P-51Ds based at Laha airbase, Ambon. One aircraft piloted by Second Lieutenant (AF) Prasetyo lost due to engine failure during the ferry flight from Makassar to Ambon. Prasetyo died after bailing out from the aircraft, landing in high-tide seas and could not be rescued by the Air Force's PBY-5 Catalina due to the extreme weather after his accident. 40 MiG-17F/PF aircraft on three airfields: Morotai (in northern Maluku), Amahai (in Seram) and Letfuan (in Kai Islands, located in the southwest of Papua). The aircraft had been stationed at Morotai before Operation Trikora for actions against PRRI-Permesta and the Republic of South Maluku separatists. The primary role of these aircraft were to provide air cover for the airlift and logistics aircraft during the early infiltration to Papua. If the war broke out, these MiG-17F/PF would provide the air cover for Tu-16 anti-shipping missions and Il-28 bombing missions, also for intercepting Dutch Hawker Hunters based in Numfor, Biak. 4 B-25 Mitchells and two A-26 Invaders at Letfuan airbase. Their primary role was for transport and providing air cover for the airlift, until this role was assumed by the P-51Ds and MiG-17F/PFs. Dutch Lockheed P2V Neptunes were known as the strongest rival for these Letfuan-based units. 18 Il-28s stationed first at Laha airbase, but then moved to Amahai airbase, due to the shortness of runway at Laha for the landing of the aircraft. 26 Tu-16s stationed in Iswahyudi Air Force Base near Ngawi, East Java in 41st and 42nd Squadron. Six aircraft were scrambled to Morotai airbase for the operation. These units were to threaten the Dutch naval fleet in Papua including HNLMS Karel Doorman (R81), the only aircraft carrier of the Dutch naval fleet. 24 Douglas C-47 Dakotas stationed at three airfields; Laha, Amahai and Letfuan. During an operation at Papua, one aircraft piloted by Captain (AF) Djalaludin Tantu and co-pilot Second Lieutenant (AF) Sukandar, was downed by a Dutch P2V. All crews bailed out safely from the aircraft, but were then captured by the Dutch forces. 10 Lockheed C-130
