The definitive version, the P-51D, was powered by the Packard V-1650-7, a license-built version of the Rolls-Royce Merlin 66 two-stage two-speed supercharged engine (it sound’s like this.. or try 14 P-51 Mustangs Simultaneous Engine Run and Takeoffs) and was armed with six .50 caliber (12.7 mm) M2/AN Browning machine guns. [1] The wing racks fitted to the P-51D/P-51K series were strengthened and were able to carry up to 1,000 lb (450 kg) of ordnance, although 500 lb (230 kg) bombs were the recommended maximum load.

The P-51D became the most widely produced variant of the Mustang. [2]

40 P51Ds were transported by ship to Australia and assembled at NEI PEP ('Personel and Equipment Pool' in Bundaberg Australia.[3] [4] They were operated by 121 (Tjililitan, Batavia) and 122 Squadrons (Polonia, Medan)[5] of the KNIL Army Air Corps (KNIL-ML).

When the war against Japan ended[6], the Dutch Mustangs were used in a futile attempt to suppress the Indonesian nationalists. When Indonesia became independent on December 27, 1949, its air arm (the Angkatan Udara Republic Indonesia, or AURI) was slated to receive two squadrons of F-51D Mustangs from the departing Dutch.

In June of 1950, the Netherlands East Indies Air Force was officially disbanded and the surviving Mustangs were transferred to the Indonesian Air Force. Indonesian Mustangs participated in several internal conflicts and remained in service with the IAF until replaced by Russian fighters in 1959. [7]

The photo of the group of men at the Lockheed Elektra was taken in Medan, at Polonia airport and probably around February '47.

There were 2 Lockheeds Electra active on 11VB Polonia.
An L-12 (Electra Junior, traffic execution, actually a 2-engine training aircraft) and an L-212, the military version of the L-12. The L-212 was mounted just above the wing just for the NL Air Force just above the plexiglass turret and it was armed. Furthermore, they were almost identical.

There was also an L-212 active on 11VB, with Serialno L-205. This military plane belonged to LuCoSu, Aviation Command Sumatra, the umbrella organization for all the squadrons based in Sumatra. It was used as a staff plane.

De L-12a, serial L2-39, registratie L2-102 (en later T-302) behoorde aan 122 sqn toe en werd als transporttoestel gebruikt. According to some sources, this plane was with the squadron until the end of January '47 and other sources say until the end of '47 and then moved to Andir / Kalidjati.

3. The Royal Netherlands East Indies Army Air Force received 40 P-51Ds and flew them during the Indonesian National Revolution, particularly the two 'politionele acties': Operatie Product in 1947 and Operatie Kraai in 1949. When the conflict was over, Indonesia received some of the ML-KNIL Mustangs. [North American P-51 Mustang; Gunston 1990 p. 39.
4. The delivery was in March, April and June 1945 (10x P-51K and 31x P-51D respectively). Of these 41 aircraft, 40 reached the ML-KNIL in Australia; they had the license plates N3-600 through N3-640. * In Australia, the Mustangs were prepared at RAAF depots. The first 19 aircraft (N3-600 / 618) received in May and June 1945 - before the Japanese surrender on August 15 - were delivered to the Dutch Personnel and Equipment Pool in Brisbane. After the Japanese surrender everything went slower. The rest only came into Dutch possession between October 1945 and March 1946; a sign of the lesser urgency of the RAAF and of a changed attitude towards Dutch colonial ambitions.
5. The 122 Squadron was officially established on November 1, 1946 and added to lucosu. In the same decision, Captain A.G. Deibel appointed commander of the squadron. On 12 November 1946 he personally led the flight of the first twelve P-51s, under the guidance of a B-25, from Tjililitan to Medan, a distance of 1390 km. In the B-25, a team from the technical service was under the command of adjutant non-commissioned officer C.W. Bastian. - Source: page 181; The Military Aviation of the KNIL 1945-1950 by Otto Ward
