EOS to Deliver Remote Weapon Systems for Australia’s Redback IFVs
Hanwha Defence Australia has contracted Electro Optic Systems (EOS) to supply Remote Weapon Systems for the Australian Defence Force’s LAND 400 Phase 3 infantry fighting vehicle (IFV) program.
The multi-year, 108-million Australian dollar ($71-million) contract includes delivery of spare parts, training, and documentation.
Under the agreement, EOS will provide upgraded R400 Remote Weapon Systems, designed to meet the Australian Army’s operational requirements and fully integrated with the AS21 Redback IFV.
Production will take place at EOS’ Canberra facility, supported by a national supply chain involving over 100 Australian companies.
“This contract is a win for Australian industry, and we are delighted to be working with Hanwha Defence Australia on this critical project for Army,” said EOS CEO Andreas Schwer.
“The work will be carried out here in Australia, supporting skilled jobs, strengthening our sovereign defence manufacturing base, and showcasing the capabilities of local suppliers on a national program of strategic importance.”
R400 Remote Weapon System
Offering accuracy and reliability, the 30mm lightweight R400 equips light vehicles with the firepower of heavier platforms.
The system is configurable for single- or dual-weapon layouts and supports mobile engagement at ranges of up to 2,000 meters (6,562 feet).
Alongside the 30mm cannon, the R400 accommodates machine guns, automatic grenade launchers, and anti-tank guided missiles, and is compatible with other EOS weapon systems through “plug-and-play” functionality.
The system is operational with militaries in Australia, North America, Europe, the Middle East, and Southeast Asia.
LAND 400 Phase 3 Program
In 2023, Australia procured 129 Redback IFVs from Hanwha Defence Australia (HDA), aimed at replacing the aging M113AS4 armored personnel carriers.
For the $4-billion Australian dollar ($2.63-billion) program, HDA’s Redback prevailed over Rheinmetall Defence Australia’s KF41 Lynx, with BAE Systems’ CV90 Mk 4 and General Dynamics Land Systems’ Ajax also initially in contention.
Production will occur in Australia, with deliveries scheduled to begin in 2027 and continue through 2028.
HDA will also provide comprehensive training, spares, and sustainment support, extending through final acceptance in 2029.
