Singapore will add three Gulfstream G550-based maritime surveillance aircraft (G550-MSA) to its military capability, the country’s Ministry of Defence (MINDEF) confirmed on Saturday. The ministry explained that these business jets will “complement the [upcoming] Boeing P-8A Maritime Patrol Aircraft as part of Singapore’s maritime security surveillance network.”

The G550-MSAs are “aircraft designed for maritime surveillance, to enhance maritime awareness and to provide early warning of maritime threats,” the statement continued. The ministry’s image appears to show an unarmed configuration similar to Israel Aerospace Industries’ (IAI’s) Conformal Airborne Early Warning (CAEW) system jointly developed with subsidiary Elta Systems.
