Singapore to acquire four P-8A Poseidon aircraft to strengthen maritime security

September 10, 2025, by Fatima Bahtić

Singapore will acquire four Boeing P-8A Poseidon maritime patrol aircraft from the United States as part of a major effort to modernize the Republic of Singapore Air Force’s (RSAF) maritime capabilities.

Minister of Defense Chan Chun Sing announced the acquisition during a meeting with US Secretary of War Pete Hegseth at the Pentagon on September 10, 2025 (Singapore time). The four Poseidon aircraft will replace the RSAF’s ageing Fokker 50 fleet, which has been in service since 1993.

The P-8A Poseidon, designed for long-range anti-submarine warfare, intelligence, surveillance, and reconnaissance missions, is expected to enhance Singapore’s ability to monitor regional waters and counter sub-surface threats.

Chan described the acquisition as the first phase of a wider refresh of Singapore’s maritime security capabilities, ensuring the SAF remains equipped to address evolving threats.

In addition, Singapore is progressing with its delivery of 20 F-35 fighter aircraft, scheduled from the end of 2026, reinforcing the RSAF’s next-generation air combat capabilities.

The purchase underscores Singapore’s strong defense ties with the US and its commitment to maintaining a technologically advanced, credible defense force, it was highlighted.

The P-8A is an aircraft designed for maritime patrol equipped with anti-submarine warfare (ASW) capabilities. It was developed based on the Boeing 737-800 commercial aircraft and is operated by nine other countries around the world, according to Boeing.

In terms of physical specifications, the P-8A has a length of 39.5 metres, a wingspan of 37.6 metres, and a height of 12.8 metres. It can reach speeds of Mach 0.73, operate at a service ceiling of more than 40,000 feet, and has a range exceeding 1,200 nautical miles.

The aircraft can carry up to 129 sonobuoys, deploy life rafts and maritime markers if fitted, and is equipped with self-protection systems and light-weight anti-submarine torpedoes. It is operated by a crew of nine.

For ASW missions, the P-8A features advanced radar systems, electro-optical/infrared cameras, and communication equipment, enabling it to detect and track surface targets while simultaneously scanning for other potential maritime threats.

The aircraft can also be deployed for search and locate operations, using its radar and sensor systems to detect surface vessels, communication systems to coordinate with other rescue assets, and deployable equipment such as life rafts and survival kits to aid survivors when fitted.
