Military MRO

The Aerospace sector of ST Engineering’s military heritage dates to 1975, when we were established as a maintenance, repair and overhaul (MRO) service provider to provide airframe maintenance for the Republic of Singapore Air Force (RSAF).  Today, we have supported over 1,500 military aircraft globally as a global MRO leader.

At ST Engineering's Aerospace sector, our military MRO capabilities range from depot-level maintenance, aircraft structural modification and upgrades, installation and rewiring of avionics and electrical systems to flight line operation for both fixed wing and rotary wing aircraft.

We are equipped to provide extensive maintenance capabilities for a wide range of fighters, transport and trainer aircraft as well as helicopters, including the F5 Tiger, F16 Falcon, A4 Skyhawk fighters, C130 Hercules, Fokker 50, KC135 Stratotanker transport aircraft as well as the H120, Super Puma and Chinook helicopters.

Reflecting our advanced capabilities, we are also an authorised service centre for C130 Hercules transport aircraft. 

In addition to all this, we can provide our customers with a wide range of military component and engine MRO.

For military components, we service key avionics and mechanical components such as radar and communication equipment, electromechanical and electronics instruments, and gyroscopic instruments; as well as landing gears, wheels and brakes, propellers, piston engines and environment control systems.

We have also established a stellar experience in servicing the following engines: General Electric F110, Pratt & Whitney F100, Honeywell T55 and Rolls Royce T56/501.

Modernising a Fleet

  • C130 Hercules Modernisation Programme

    As an approved Lockheed Martin Hercules service centre, we are the premier one-stop centre for the C130 Hercules aircraft. We provide airframe, engine and component MRO, landing gear and parts support, as well as modifications that include obsolescence upgrades, aircraft systems/avionics modernisation and structure life extensions. 

    To date, we have redelivered more than 600 C130 aircraft, providing nose-to-tail solutions to C130 operators globally. For the C130 modernisation programmes, system upgrades may include avionics upgrading from analog to digital systems, replacement of older gas turbine compressors/air turbine motors (GTC/ATM) with newer auxiliary power units (APU) and upgrading of environmental control systems (ECS) to higher-cooling capacity versions. 

    In 2007, the Republic of Singapore Airforce became ST Engineering’s first customer for the C130 glass cockpit upgrades for the modernisation of its fleet of 10 C130 aircraft. In 2012, we were awarded a contract from the Royal Air Force of Oman for a full-scale maintenance and modernisation solution for three of its C130 aircraft.

  • Helicopter Avionics Modernisation & Operational Capability Upgrades

    We can provide avionics modernisation as well as operational capability upgrade and obsolescence management solutions for helicopters. Our proven solutions include integrated digital glass cockpit upgrades, a complete digital automatic flight control system and a dual independent rescue hoist system.

    In addition, we can carry out a customised design and equipment installation for the Aircraft-Ship-Integrated-Secure-&-Transverse (ASIST) system to allow for sea-borne applications. With this, helicopter operators are able to fly more often thus enhancing mission effectiveness.
