Singapore’s Terrex May Replace Poland’s Rosomak APCs on Domestic Assembly Lines

Poland is considering the Singaporean Terrex armored personnel carrier as a potential replacement for its locally produced Rosomak APCs, Defence24 reported.

During an official visit to Singapore, Polish President Andrzej Duda announced preliminary agreements on Warsaw’s involvement in developing a new wheeled armored personnel carrier for the Polish Armed Forces.

At the center of the discussions is the Terrex S5 — the latest iteration of the Terrex APC developed by Singapore’s ST Engineering and introduced in 2024.

According to Duda, Poland is seeking a technological partnership, under which Polska Grupa Zbrojeniowa and WB Electronics could launch domestic production of the new vehicle, gradually phasing out the Rosomak, which is currently manufactured under license from Finnish firm Patria.

ST Engineering executives confirmed that Poland had expressed interest in co-producing the new combat vehicle, potentially replacing the Rosomak fleet. The company has over a decade of experience designing, manufacturing, and upgrading various armored platforms, including APCs.

The Terrex S5 is an eight-wheeled armored personnel carrier with a combat weight of 35–37 tonnes. It is designed for a two-person crew (driver and commander/gunner) and can transport up to 10–12 troops.

Powered by a 711-horsepower Caterpillar diesel engine, the vehicle features a 7-speed automatic transmission with two reverse gears. It can reach speeds of up to 120 km/h and has an operational range of up to 1,000 km. A hybrid powertrain allows for silent movement over distances of up to 50 km.

Armor protection is rated STANAG 4569 Level 4, defending against 14.5 mm armor-piercing rounds. The platform also accommodates an active protection system (APS).

Militarnyi previously reported that Poland has ordered over 100 domestically produced Borsuk infantry fighting vehicles and is currently preparing production facilities to meet demand.
