SINGAPORE, July 23 — Singapore is committing S$4 billion (RM12.7 billion) over the next 15 years to overhaul its air navigation services, a massive investment designed to cement the city-state’s status as a premier global aviation hub.

The upgrade includes a comprehensive refurbishment of Changi Airport’s iconic control tower and the integration of next-generation systems at the Singapore Air Traffic Control Centre (SATCC), The Straits Times reported

Civil Aviation Authority of Singapore (CAAS) Director-General Han Kok Juan stated that the move is essential to meet a projected tripling of global air passenger traffic over the next 25 years, with the Asia-Pacific region expected to drive half of that growth.

“As Singapore builds capacity on the ground to handle rising passenger traffic, it is important that we also build capacity in the skies,” Han said. “This ensures we provide smoother, safer, and more sustainable air services to travellers.”

The most visible part of the project is the renovation of the 80m-tall Changi Control Tower. Beyond a new facade and the construction of an annex connecting the tower to Jewel Changi Airport, the refurbishment addresses critical safety concerns regarding the building’s exterior. Work begins in November and is expected to conclude by the end of 2028.

Parallel to the tower’s facelift, CAAS is constructing a new SATCC complex. This facility will house an info-centric air traffic management tool that uses predictive analytics to identify and resolve traffic bottlenecks before they occur. The new system will be a quantum leap in capacity, capable of tracking up to 4,000 aircraft simultaneously in real time, doubling the current limit.

These upgrades are critical for Changi’s transition to three-runway operations by the end of the decade. Furthermore, the opening of Terminal 5 in the mid-2030s is expected to nearly double the airport’s size, boosting annual passenger throughput from 90 million to 140 million.

To manage this surge, CAAS is aggressively expanding its human capital. The authority plans to increase its workforce of air traffic controllers by 40 per cent, adding 200 new specialists by the mid-2030s. To attract local talent, CAAS is introducing a management associate programme for fresh graduates and a dedicated air traffic control specialisation in partnership with a local university.

The S$4 billion investment is strategically divided. The bulk, S$3.2 billion, is earmarked for new systems and infrastructure maintenance. Another S$500 million will fund the recruitment and training of the new controller cohort, while the remaining S$300 million will be dedicated to developing emerging technologies with industry partners.

By incorporating artificial intelligence and high-resolution digital views of the airfield, CAAS aims to move beyond the physical constraints of traditional towers, allowing controllers to make faster, data-driven decisions in an increasingly crowded sky.
