CAAS Taps Thales for AI-Powered Air Traffic System to Handle Singapore's Growing Skies

Singapore's airspace — already one of Asia's busiest — is about to get an AI brain. The Civil Aviation Authority of Singapore has awarded Thales a contract to build the NexGen Air Traffic Management System, powered by the French defence-and-aerospace giant's TopSky — ATC One platform. The system, which replaces the current LORADS III, will introduce AI-based aircraft sequencing to optimise arrival and departure flows at Changi, reducing delays, fuel burn, and carbon emissions in the process.

The AI engine at the heart of the new system is TopSky — Sequencer, a machine-learning-based solution that predicts and manages aircraft trajectories in real time. Rather than relying on fixed schedules and controller intuition alone, it dynamically sequences aircraft to minimise holding patterns and runway congestion. The system also incorporates cybersecurity technologies compliant with both International Civil Aviation Organization standards and Singapore's domestic requirements. Two new-generation air traffic control radars will provide 24/7 detection capability, including during adverse weather.

The Thales contract fits into a longer arc of aviation infrastructure investment in Singapore. CAAS has committed S$4 billion to air navigation upgrades ahead of Changi Terminal 5's opening in the mid-2030s. The NexGen ATMS, targeted for operational service by 2030, is a foundational piece of that puzzle — T5 cannot operate at full capacity without a modernised traffic management backbone. The project also includes knowledge-transfer initiatives, with CAAS officers embedded in Thales's project office in France and localisation programmes in Singapore to build domestic capability.

For Singapore, the payoff is both operational and strategic. An AI-enabled air traffic system can handle higher aircraft volumes with the same — or even reduced — controller workload, which matters as regional air travel demand grows and the workforce of experienced controllers remains constrained. Thales senior executive vice-president Pascale Sourisse framed the project as an extension of the company's decades-long partnership with CAAS, noting that the joint experience from the LORADS III programme enabled the co-innovation that produced the new system.

Why it matters for Singapore: The CAAS-Thales project is AI infrastructure at scale — not a chatbot or a recommendation engine, but a safety-critical system managing thousands of lives in real time. Its selection signals Singapore's willingness to bet on AI in the most regulated, least forgiving domain possible: air traffic control. If the system delivers as promised, it becomes a reference case for AI adoption in critical national infrastructure — exactly the kind of credibility-building deployment that Singapore's trusted-AI narrative needs.
