The Republic of Singapore Air Force is set to acquire maritime surveillance aircraft as part of its mission to further secure the trade-dependent city-state’s sea lines of communication.
Singaporean Defense Minister Chan Chun Sing announced the plan to purchase three Gulfstream G550-Maritime Surveillance Aircraft (G550-MSA) during a recent Committee of Supply Debate, which is Singapore’s parliamentary process where ministries justify planned spending before approval.
The G550-MSAs are positioned to complement the four Boeing P-8A maritime patrol aircraft — designed for anti-submarine warfare — that Singapore ordered in September 2025 as a replacement for its aging Fokker 50 maritime patrol/light transport fleet.
G550 Specifications
Singapore’s defense ministry released a fact sheet regarding the G550-MSA, built for maritime surveillance and early warning functions.
The aircraft measures 29.8 meters (97.7 feet) long and stands at 8.3 meters (27 feet) high, with a 28.5-meter (93.5-foot) wingspan, and can accommodate two pilots and up to six crew members.
It is fitted with mission systems, including a radar, electro-optical/infrared cameras, a self-protection suite, integrated communications systems, and a maritime automatic identification system.
The G550-MSA operates at a top speed of 0.82 Mach (1,012 kilometers/629 miles per hour) with a service ceiling of 40,000 feet (12,192 meters). It can remain airborne for up to nine hours.
Strengthening Singaporean Defense
Apart from the G550-MSA acquisition, the minister outlined plans to scale the use of uncrewed platforms, pair them with manned systems, and mix “high-end conventional systems with cheap, dual-use systems” to efficiently address fast-evolving threats.
He also gave an update on the Republic of Singapore Navy’s Victory-class Multi-Role Combat Vessel (MRCV), intended to function as a mothership for deploying manned and unmanned systems while possessing the combat capability of a modern frigate.
Singapore contracted ST Engineering Marine to build a fleet of six MRCVs in 2023.
The Singaporean shipbuilder launched the lead ship in October 2025 and conducted the keel-laying for the second Victory-class MRCV in January 2026, which is on track to be launched in the third quarter of this year.
The navy is expecting to receive the combat vessels starting in 2028.
