Singapore’s Boeing F-15SG fighter aircraft have achieved full operational capability (FOC) three and a half years after the first deliveries.

"The RSAF's F-15SGs have been rigorously tested and proven superior in air defence and strike capabilities, and integrated with other air platforms within the RSAF, which together are able to respond to a spectrum of threats to defend and dominate our skies,” defence minister Ng Eng Hen said during a ceremony to mark the occasion.

“A strong [air force] provides confidence that Singapore is well capable of defending its sovereignty and protecting our precious homeland."

An evolution of the US Air Force's F-15E Strike Eagle, the F-15SG is the most capable type in Singapore’s air force. It includes the Raytheon APG-63(V)3 active electronically scanned array radar, the Lockheed Martin Sniper targeting pod, infrared search and track sensor and an Israeli-supplied electronic warfare system.

Singapore has 24 F-15SGs. Several units are based at the US Air Force’s Mountain Home air base in Idaho, where Singaporean pilots and technicians have received training on the new type.
