Written Reply by Minister for Defence Chan Chun Sing to Parliamentary Question on Security Threats Against National Security Sites on 24 Feb 2026

Mr Yip Hon Weng asked the Coordinating Minister for Public Services and Minister for Defence (a) how many security threats against national security sites occurred in the past year and how much resources were expended on investigations; (b) of these, how many were hoaxes and what are the primary motives for such false threats; and (c) what measures are being taken to minimise such occurrences while ensuring all unconfirmed threats continue to be treated with necessary seriousness. 

Minister for Defence, Mr Chan Chun Sing:  

The SAF treats the security of our camps and bases seriously and takes the necessary measures to ensure safety of our personnel and assets. The SAF has multi-layered security processes and systems in place to deter, detect, deny and respond against security threats to our camps and bases. To deter potential perpetrators, SAF camps and bases conduct frequent security patrols and operations. Perpetrators can expect stiff punishments including imprisonment. To detect and deny potential threats, SAF camps and bases are equipped with security infrastructure such as fencelines, surveillance and intrusion detection systems, and vehicular scanning capabilities. Security personnel are also on watch round-the-clock at the camps and bases.  

While our efforts should deter would-be perpetrators, potential security threats of varying levels of credibility and risks may still arise. The SAF assesses all potential threats robustly, and we adopt a zero-tolerance stance because the consequences are serious. When deemed credible, the SAF will take the required precautions and counter-measures to deal with the threat to keep our people, equipment and infrastructure safe. The SAF’s responses include evacuations, bomb sweeps, and personnel checks. It has ready responses to deal with perpetrators and other threats. The SAF would work with the SPF and other Government agencies to pursue perpetrators.  

During the recent bomb hoax at Paya Lebar Air Base and thereafter, the SAF responded as planned. The SAF worked with the Singapore Police Force to identify and apprehend the perpetrator promptly. The case is currently under investigation.
