Safety concerns have, for now, grounded plans by the Republic of Singapore Air Force (RSAF) to fly a radar-equipped balloon that can spot hostile threats coming from as far as Malacca.
The 55m-long helium-filled military blimp, known as an aerostat, was supposed to be airborne early last year to watch over Singapore.
But its launch was delayed because the giant balloon's United States-based manufacturer TCOM has failed to meet the RSAF's safety and operational requirements, The Sunday Times has learnt.
