Seletar Airport, Singapore's secondary civilian gateway, has finished building a new control tower as part of its $116 million 'Aerospace Park' plans.

The new tower, which will allow for the airport to accommodate all-weather flight operations for the first time, comes four months after it finished a 250-metre extension of its runway to allow for bigger aircraft.

Since upgrading works started in 2008, more than $116 million has been invested into the gateway on upgrading and expansion works to "strengthen its capabilities" .

Singapore is investing heavily into Seletar Airport and its surrounding areas to transform it into the 'Seletar Aerospace Park', which it hopes will become a "premier aerospace hub in the region" .

Launched in 2007, the Seletar Aerospace Park (SAP) is a multi-agency project that is expected to contribute $3.3 billion to the Singapore economy and add more than 10,000 jobs.

According to Changi Airport Group (CAG), which manages the airport, Singapore has seen strong growth in the business aviation sector recently, with aircraft movements growing at a compounded annual growth rate of 17% from 2007 to 2010.

Lee Seow Hiang, chief executive of CAG, said: "Seletar Airport is the backbone of SAP, providing the connectivity to the region needed to spur the growth of the SAP community.

"The successful completion of key infrastructure developments at Seletar Airport will enhance its operational efficiency and strengthen its capabilities, thereby delivering better services to meet the needs of airport users."

The modernisation of the gateway, of which the new control tower is a key aspect, is intended to support the increase in business aviation activities in Singapore.
