Singapore Eyes 6th-Gen Fighters After F-35: Where Does Indonesia Stand?

Singapore has initiated informal, exploratory talks to potentially join the Global Combat Air Programme (GCAP), a tripartite sixth-generation fighter jet development project led by the United Kingdom, Italy, and Japan, according to a report by defense publisher Janes. If the Southeast Asian nation formally enters the initiative, it would mark a significant expansion of its defense procurement strategy following its landmark acquisition of United States-built F-35 stealth fighters.

Exploring the Global Combat Air Programme (GCAP)

According to Janes, Singaporean authorities are currently gathering information through preliminary discussions rather than negotiating active membership. The government has not yet committed to participating in the multinational defense pact. This cautious approach aligns with the operational timeline of the Republic of Singapore Air Force (RSAF), which is currently awaiting the initial delivery of its American-made stealth jets.

GCAP represents the primary Western sixth-generation combat aircraft development effort outside the United States, targeting a deployment window around 2035 to replace legacy platforms. Beyond the manned aircraft, the program encompasses advanced sensors, artificial intelligence integration, networked data systems, specialized weaponry, and autonomous loyal wingman drones.

Current RSAF Fleet and Upcoming F-35 Deployments

The RSAF maintains one of the most technologically advanced air arms in Southeast Asia, driven by sustained military investment. Current operational assets include 40 F-15SG strike aircraft alongside 49 legacy F-16C/D fighters spanning the Block 52 and Block 52+ variants, according to defense data.

The transition to fifth-generation capabilities involves a total order of 20 advanced aircraft. Singapore has purchased 8 conventional takeoff and landing (CTOL) F-35A jets and 12 short takeoff and vertical landing (STOVL) F-35B variants. The F-35B units are slated to arrive first, with initial deliveries commencing before the end of the year. Initial training operations will take place at Ebbing Air National Guard Base in Arkansas, United States, before the first F-35B airframes physically relocate to Singapore by 2029.
