ST Engineering Showcases Advanced Terrex s5 Armored Vehicle at Singapore Airshow 2026

Overview of Recent Developments

At the Singapore Airshow 2026, held from February 3-8, ST Engineering prominently displayed its latest iteration of the Terrex s5 8×8 armored vehicle. This event followed a significant procurement agreement with the Singapore Army, wherein the Titan infantry fighting vehicle (IFV)—a derivative of the Terrex s5—was confirmed for adoption.

Procurement Contract and Specifications

The contract, announced on January 26, includes provisions for a revamped Titan IFV based on the Terrex s5 platform, which weighs approximately 35 tons. The Singapore Army, in collaboration with the Ministry of Defence (MINDEF) and the Defence Science and Technology Agency, is working closely with ST Engineering to enhance the vehicle with specified advanced capabilities. Deliveries of the Titan IFV are scheduled to begin in 2028.

Key Features of the Titan IFV

• Armament: The Titan IFV is reported to possess enhanced firepower, featuring a remote-controlled weapon station equipped with a 30mm cannon. However, ST Engineering has clarified that this specific armament may not be the final choice for the production model.
• Mobility and Engineering Innovations: Lim Kok Ann, the president of Land Systems at ST Engineering, emphasized the vehicle’s mobility, advanced technological integration, and adaptability—qualities intended to enhance Singapore’s future operational capabilities.

Technological Enhancements

The prototype showcased at the airshow includes notable advancements such as:

• Hybrid Electric Drive: This propulsion system offers substantial power for onboard systems and sensors, creating advantages in both energy efficiency and spatial configuration. Nevertheless, it remains uncertain whether this hybrid model will be the variant deployed by Singapore, as a conventional diesel engine option is also available.
• Network-Centric Operations: MINDEF has highlighted that the Titan is designed with integrated digital systems, sophisticated vehicle electronics, and a robust command-and-control architecture. This facilitates a networked approach to motorized operations, enhancing battlefield coordination.
• Autonomous and Unmanned Systems Integration: The Terrex s5 prototype features rear-mounted launcher boxes capable of deploying reconnaissance drones. It can also control unmanned ground vehicles, such as ST Engineering’s Taurus 4×4, from within the vehicle.

Autonomous Capabilities and Command Interface

During the airshow, ST Engineering introduced a proof-of-concept titled the Vehicle AI Cockpit. This cutting-edge solution utilizes artificial intelligence across several domains:

• Vehicle Control: AI algorithms automate essential maneuvers, optimizing operational efficiency.
• Surveillance: A top-mounted camera offers a 360-degree view of the vehicle’s surroundings, with real-time automated identification of objects via color-coded alerts.
• Manned-Unmanned Teaming: The cockpit design includes two adjacent control stations enabling operators to seamlessly pivot between vehicle operation, weapon deployment, and unmanned system management.

Operators can utilize a voice-activated interface, named Nova, for streamlined operations—including selecting optimal driving modes.

Physical Specifications and Export Potential

The Terrex s5 boasts a length of 27 feet, accommodating up to 12 personnel and a payload capacity of 13 tons. Given the robust specifications and advanced features, ST Engineering is actively promoting this variant for export opportunities, aiming to enhance its footprint in international defense markets. As Singapore continues to modernize its military capabilities, the Terrex s5 stands poised to serve as a versatile platform in the evolving landscape of defense technology.
