The local training school comprises Skadron Pendidikan 101 with some 30 Grob G-120s two-seat turboprop trainers and Skadron Pendidikan 102 with the KT-1B

Another of the local Wong-Bees. Discretion is advised when photographing active military aircraft in this part of the world - I made sure I wasn't being watched!

The Indonesian AF Museum is close to the end of the runway at Adisutjipto airport so the busy resident flying school provides lots of aerial activity as the students pound the circuit. The TNI-AU's Skadron Pendidikan 102 have received 17 KT-1s in three batches, seven between 2002 and 2005, five in 2007/8 and seven assembled at Bandung between 2012 and 2014. Four have been lost in accidents. Note the badge and team number of the IAF 'Jupiter' aerobatic team on tail.

In September 1976, the first of sixteen OV-10F COIN aircraft were delivered to SkU.3. Initially serialled in the S-1.. range, they were frequently used in the former Portuguese East Timor from 1977 (together with the A-4E and F-5E) to deal with continued opposition to the occupation which resulted in Timor becoming an Indonesian province. The first F-16s were delivered in December 1989 and replaced the OV-10s in SkU.3, the Broncos then being used to reactivate SkU.1. After accidents in 2005 and 2007, the type was grounded.

The Nu-200 was an Indonesian design for a simple COIN/ground support aircraft first flown in August 1954. According to the plate with the aircraft, three were built, but most sources refer only to this prototype (which may have used the Australian Wackett Trainer as its basis) and a single example of the Nu-225 development which was grounded in 1967. The Nu-200 was placed on display in 2017.

In September 1980, the first Hawk T.53s were delivered to Wing Pendidikan 1 and were operated next to the venerable old L-29s, initially using the LL-53.. serial range, later changed to TT. In 1991, BAe and Indonesian Aerospace (IPTN) signed an agreement for collaborative production of the Hawk and more orders were anticipated, but exports were eventually blocked due to concerns over Indonesian human rights, particularly in East Timor. However in June 1993, the TNI-AU successfully ordered eight Hawk Mk.109s and 16 Mk.209s from BAe, supplemented by 16 additional Mk.209s in 1996

Along with F-5s arriving in April 1980 were 14 A-4Es and two TA-4Hs from surplus IDF/AF stock. They replaced the T-33A with SkU.11. From 1982, SkU.12 was reactivated with a second batch of 16 ex-Israeli A-4s, the best remaining ones being transferred out in 1996 to SkU.11. TT-0440 was 1964-build aircraft BuNo 151110, which served eight different USN units before being struck off charge at Pensacola in 1972 and transfer to Israel. On arrival in Indonesia, put into service with SkU.12 at Pekanbaru AB. Wfu and stored at Adisutjipto AB from 2002. Previously displayed in green/brown camouflage.

Between 1973 and 1975, following the improvement in relations with Australia, 23 second-hand CAC-27 Sabres were donated to replace the MiG-21s with SkU.14 (Iswahjudi AB) that had become unserviceable due to the embargo on spares from the USSR. Five of them were also ex Malaysian. They were initially serialled with an F- prefix.

In April 1980, the first of twelve F-5Es and four F-5Fs arrived for the TNI-AU as replacement for the CAC-27 Sabres with SkU.14. Two were written off but all the others have been preserved.

Delivered new as part of an order for eight from Fokker in November 1976 as T-2707 and reserialled A-2707 in service with SkU.2 at Halim in 1992, grounded June 2012

Repainted in its original colour scheme and serial, the AURI's first Hercules, delivered in 1960 ex 58-0748. Operated by SkU.32 as T-1301 until transferred to Pelita as PK-VHD in 1978, returned in 1982 as A-1301. W/o in a hard landing at Bandung, stored and put on display at the Museum in 2018

Carrying the badge of DUAM, as per the roof titles which translate as 'Military Air Transport Service', this C-47 was delivered to the USAAF as 42-92870 in 1944 and post-war served the RAAF (NEI) and then the ML-KNIL (Royal Netherlands East Indies Army AF) as NI-474. It was transferred to KNILM (Royal Dutch Indies Airways) in 1947 as PK-DPE and Garuda in 1949, reregistered PK-GDT in 1957 but at various stages served the military as T-474 in several of the regional conflicts in which Indonesia was involved. In 1982 it carried out a flight marking the anniversary of the armed forces.

A genuine Royal Netherlands AF Hunter, one of 12 ferried aboard the Dutch aircraft carrier Karel Doorman to New Guinea in 1960. They were operated by the Dutch against Indonesian attempts to take control of New Guinea through into 1962. N-112 was damaged beyond repair following a crash into the sea off Biak in August 1962

A special exhibit. One of 26 Badgers supplied during the period of co-operation with the USSR from 1961, serving SkU.41 and 42 at Iswahjudi AB, Madiun until the end of the 1960s when relations with Russia broke down and parts became embargoed. They were active during the Indonesian confrontation with Malaysia, flying sorties into Malaysian airspace near Singapore. Of the 26, 12 were the Tu-16KS-1B variant which was equipped to carry two Kennel air-to-surface missiles on underwing pylons as displayed here. Unfortunately it is impossible to photograph it satisfactorily under the protective roof.

Another aircraft displayed near the main base gate through which the Museum Pusat TNI-AU Dirgantara Mandala is accessed. There is some doubt as to this Cessna's true identity - if the c/n shown here is correct, it is ex R-382 but it seems at some stage it was marked as LM-4188 (which is recorded as preserved at Abdul Rahman Saleh AB). The way the serial is painted doesn't look quite right so the jury is out on this one.

Displayed near the main Air Force gate on the road that leads to the Museum. Swiss-built AS202 Bravos replaced the last T-34A Mentors with the main training school here at Adisutjipto AB from 1981, operating till 2015. The LM serial prefix derives from "Latih Mukla", translating as elementary trainer.

One of 18 L-29 basic jet trainers that operated with No 1 Training Wing here at Adisutjipto AB from 1965 to 1983, becoming the last Soviet Bloc type to be withdrawn.

First flying in 1995, the N250 was Indonesia's first indigenous effort to gain a foothold in the market for regional turboprops, but the project fell victim to the financial crisis affecting Asia in the late 1990s and only two were built. There had even been talk about production lines being established in the UK and USA. In the 2010s a cheaper and simplified development to be known as the R-80 was mooted, an MoU being signed with Leonardo, but it remains to be seen whether this proceeds. PK-XNG is the N250 prototype, placed on display here in 2020

A real star of the collection for me, one of 21 Czech-built Il-14s that were part of a large number of aircraft supplied by Czechoslovakia to support a re-equipment programme begun in 1958. They were stationed at Halim Perdanakusuma, Jakarta with transport units SkU.2 and SkU.17 and the last is thought to have operated till 1975

Built in some quantity in Indonesia by Lipnur, a predecessor of IPTN, the Wilga (known locally as Gelatik) was used by the Air Force's agricultural unit, the Satuan Udara Pertanian after formation in 1961. Their first base was Kemayoran Airport, Jakarta. The PZL-104s were supplemented by the PC-6 in 1977 and later by Cessnas. The military-backed Federasi Aerosport Indonesia also flew the type. This one has been on show since 1984
