Australia will assemble mtu engines and Allison transmissions and integrate them locally into complete powerpacks for the Hanwha Redback Infantry Fighting Vehicle should it be selected for service in the Australian Defence Force. Penske Australia will also embed a team of specialist technicians within Hanwha’s manufacturing facility to support the assembly and integration of the powerpack into the Redback vehicles during production. 

The proposed Redback engine.

The Redback is under consideration by the Commonwealth under an ongoing tender process for Project LAND 400 Phase 3, which is an $18 billion to $27 billion project tasked to acquire up to 450 Infantry Fighting Vehicles. The 1,000hp eight-cylinder mtu MT881Ka-500 diesel engines will be built and tested locally enabling the in-country sustainment by Penske Australia under a technology transfer agreement with STX Engine of South Korea. STX Engine, under licence from mtu, have localised and modified the engine over several decades and will be directly involved in knowledge and skills transfer. 

The mtu engine variant for the Redback is a high speed, water-cooled, twin-turbo, four-stroke, direct injection, intercooled diesel, the same as that used in Hanwha’s K9 self-propelled howitzer and comes with a proven reputation for performance and reliability. In a similar arrangement, Penske Australia will also conduct local assembly and testing of the Allison X1100 series cross drive transmission under licence using kits supplied by SNT Dynamics, a South Korean company and long-term supply partner of Allison.

The proposed Redback transmission.

The Allison variant selected for the Redback is a cross-drive transmission with proven technology, operational in Hanwha’s K9 self-propelled howitzers fleets around the globe as well as the X1100 series transmission fitted to the Abrams M1A1 main battle tank which has been in-service with the ADF since 2007. It is more than capable of handling the Redback’s 40-plus tonne combat weight and the staggering 3030 Nm of torque generated by the mtu engine. Penske Australia’s assembly of the Redback’s X1100 transmission will also expedite the establishment of a viable local deep-maintenance hub for other X1100 Allison cross-drive units users locally and internationally. The new maintenance hub will negate the need for these transmissions to be exported for overhaul and make a practical contribution to Australia’s sovereign defence support capability applicable across multiple programs.

Once the engine and transmission units are assembled and tested, they will be delivered to Hanwha’s armoured vehicle manufacturing facility in Greater Geelong where an on-site Penske Australia team will support assembly of the powerpack ahead of vehicle installation with HDA. Hanwha Defense Corporation, as the design authority for the powerpack, will enable the knowledge, skills and intellectual property transfer to the Australian companies. 

The strong Australia, South Korea connection in what is a fundamental part of the Redback program has been 18 months in the making. Bringing together companies from Australia and South Korea is one of the key objectives of Hanwha Defense Australia’s Industry Development Strategy.
