Singapore Partners With Thales to Build Next-Generation Air Traffic Management System and Advanced Radar Network for Future Aviation Growth 2026

Singapore is overhauling its entire air traffic control infrastructure by replacing the long-standing LORADS III platform with Thales' AI-powered TopSky – ATC One system. The Civil Aviation Authority of Singapore (CAAS) has formalised a major technology partnership with Thales to deploy a next-generation Air Traffic Management System (ATMS) alongside two advanced surveillance radars, positioning the city-state to handle surging aircraft movements across one of Asia's most congested air corridors.

The agreement marks a structural shift in how Singapore will monitor, sequence, and manage flights. The existing LORADS III platform will be retired in favour of Thales' TopSky – ATC One — a system built around real-time data processing, an intuitive human-machine interface, and artificial intelligence-driven sequencing tools. CAAS officers will participate directly in the project office in France, with parallel development activities running in Singapore to build domestic technical expertise.

Secure European Cloud Approval Already Secured

A foundational cybersecurity milestone has already been achieved before full deployment begins. The European Commission and France's National Cybersecurity Agency (ANSSI) have granted the Restreint Union European approval (R-UE/EU-R), enabling secure interconnection between Thales' R-Cloud environment and the European Commission's R-UE/EU-R network.

This approval establishes a protected communication channel for cross-border aviation data exchange — a prerequisite for any modern ATMS that must interface with international airspace networks. The certification also signals that Singapore's new system will operate under cybersecurity frameworks recognised by both ICAO and European authorities, rather than relying on proprietary or isolated security standards.

AI-Powered Sequencing to Cut Fuel Burn and Holding Times

The operational centrepiece of the NexGen ATMS is the integration of TopSky – Sequencer, an artificial intelligence-powered aircraft sequencing solution. Rather than relying on manual controller coordination for arrival and departure spacing, the system computes optimised traffic flow patterns automatically.

The practical impact centres on three outcomes:

Reduced unnecessary holding times for arriving aircraft
Improved coordination between departure, en-route, and approach phases
Lower fuel consumption and reduced carbon emissions from more efficient flight paths

This aligns with Singapore's broader sustainability objectives for its aviation sector, where even marginal reductions in holding patterns across a high-density hub can translate into measurable emissions savings over time.

Open Architecture Designed for Decades of Upgrades

The TopSky – ATC One platform has been built with an open architecture, allowing future integration of third-party solutions and technology upgrades without requiring complete system overhauls. This design choice matters because air traffic management is evolving rapidly — with automation tools, advanced surveillance feeds, and new operational concepts entering the market on shorter cycles than traditional ATMS replacement timelines.

The scalable framework means Singapore can adopt emerging technologies as they mature, rather than being locked into a single vendor's ecosystem for the platform's entire lifecycle. Cybersecurity protections embedded in the system meet requirements set by both ICAO and Singapore's national aviation security standards.

Two New Radars to Deliver 24-Hour Surveillance

Alongside the ATMS replacement, Thales will deliver two advanced air traffic control radars to strengthen Singapore's aircraft surveillance infrastructure. These systems are designed for continuous 24-hour monitoring, including during adverse weather conditions that can degrade older radar performance.

The radars will feed directly into the NexGen ATMS, giving controllers more accurate and reliable flight data with enhanced visibility across Singapore's airspace. The combination of upgraded surveillance hardware and AI-assisted automation is expected to improve situational awareness and decision-making precision for controllers managing complex traffic flows.

Why This Matters for Asian Aviation Capacity

Singapore sits at the centre of one of the world's busiest aviation corridors. Passenger demand across Asia continues to climb, placing increasing pressure on airspace efficiency and air traffic control capacity. Legacy systems like LORADS III, while reliable, were not designed for the traffic volumes and operational complexity that current growth trajectories demand.

The NexGen ATMS project addresses this gap by providing a platform that can scale with traffic growth while simultaneously improving safety margins and sustainability metrics. The partnership also builds local expertise — CAAS officers working alongside Thales engineers in France will bring operational knowledge back to Singapore, strengthening the domestic talent base for future system management.

Pascale Sourisse, Senior Executive Vice-President, International Development at Thales, framed the project as a continuation of an established working relationship rather than a greenfield deployment. Thales' prior experience delivering LORADS III with CAAS provided the testing and co-innovation foundation needed to develop solutions tailored to Singapore's specific airspace requirements.

Frequently Asked Questions

What system is Singapore replacing with the new Thales ATMS? Singapore is retiring its existing LORADS III air traffic management platform and replacing it with Thales' TopSky – ATC One next-generation system.

How will the new system reduce carbon emissions? The integrated TopSky – Sequencer AI tool optimises arrival and departure sequencing, reducing unnecessary holding times and improving traffic flow — which directly lowers fuel consumption and emissions.

Where is the NexGen ATMS being developed? Development is split between a project office in France, where CAAS officers are participating, and additional development activities in Singapore.

What cybersecurity certification has the project received? The system has received Restreint Union European approval (R-UE/EU-R) from the European Commission and France's National Cybersecurity Agency (ANSSI), enabling secure cloud interconnection.

How many new radars will Thales deploy in Singapore? Thales will deliver two advanced air traffic control radars designed for continuous 24-hour monitoring, including during challenging weather conditions.

Singapore's bet on AI-driven sequencing and open-architecture ATMS design signals that the next decade of Asian aviation growth will be managed by software, not just airspace expansion.
