PT Dirgantara Indonesia (Persero)

PT Dirgantara Indonesia, which trades internationally as Indonesian Aerospace, is the largest aircraft manufacturer in Southeast Asia and the airborne platform member of Defend ID, the state defence holding built around PT Len Industri. It was set up in Bandung in 1976 under B.J. Habibie, drawing on assets from Pertamina and the air force's own Nurtanio institute, and has since delivered more than 470 aircraft to over 50 customers across Asia Pacific, the Middle East, Africa and Latin America. The company traded as IPTN until August 2000, when it was renamed and repositioned around engineering, subcontract manufacturing and after-sales work rather than whole-aircraft programmes alone. Four lines carry it: aircraft, aerostructure, aircraft and engine services, and engineering services and weapon system.

Fixed wing production centres on three types. The NC212i light transport traces back to a 1974 licence with CASA and is still being delivered to the Indonesian Air Force, the CN235-220 serves in civil, military transport and maritime patrol fits with Indonesian and export operators, and the N219 is a 19 seat twin turboprop certified in December 2020 for short multi-hop routes into rough strips. Rotary wing work runs through licence and partnership arrangements. PTDI assembles, customises, delivers and supports the H225M, H215, H125M, H135M and H145M and the AS565 MBe naval helicopter for Airbus Helicopters, and it produces and jointly markets the Bell 412EPI.

Aerostructure has pulled the company into the global airframe chain. It builds horizontal and vertical tail planes and rear fuselages for the Airbus C295 and hosts that aircraft's final assembly line, delivery centre and service centre, keeps the Super Puma AS332 in production, manufactures tail booms and fuselages for MkII Super Puma and Cougar helicopters, and supplies tail booms, door assemblies, door posts, pylons and ducts for the Bell 412 series and Huey II. Detail parts, component manufacture and assembly for Airbus, Boeing and Bell fill out the shop floor.

Aircraft and engine services covers maintenance, overhaul, spares and customer support, and reaches into propulsion through subsidiaries. Nusantara Turbin dan Propulsi handles engine and industrial turbine work at Bandung, GE Nusantara Turbine Services repairs combustion turbines and their components in a venture with GE Vernova, and IPTN North America supplies parts and services to operators from Seattle.

Engineering services and weapon system is the smallest line and the one that reaches furthest from airframes. PTDI works as a mission system integrator, builds simulators, designs airports, develops software and consults on information and communications technology. It also designs and manufactures aircraft derived products including rockets, missiles, unmanned aerial vehicles and torpedoes, and it is Indonesia's industrial participant in the KF-X and IF-X fighter programme run with Korea Aerospace Industries.
