Calibrating the Singapore-US Security Anchor for a New Era: An American View

In June, US Secretary of War Peter Hegseth declared at the Shangri-La Dialogue that Washington wants “partners, not protectorates”. The statement sent a tremor through the Indo-Pacific. This embrace of transactional realism — compounded by sweeping US tariff hikes that have rattled export-dependent Southeast Asian economies — signals a harder, more extractive era of US statecraft. Yet, far from threatening the Singapore-US relationship, this shift offers an opportunity. Washington’s insistence on hard power and burden-sharing plays to Singapore’s ethos of self-reliance.

Singapore has never asked for a free ride. As a Major Security Cooperation Partner by choice rather than a formal treaty ally, Singapore pays its own way. Its recent multi-billion-dollar acquisition approval for advanced US-made F-35 Joint Strike Fighters is the latest proof point of a robust and self-funded deterrence strategy. In exchange, the 1990 Memorandum of Understanding and its subsequent updates secure logistical anchors for the US military at Changi Naval Base and Paya Lebar Air Base. Singapore also hosts the second-largest permanent foreign military training contingent in the continental US. This is a symbiotic, functional relationship that Tim Huxley, an analyst who has written about the Singapore Armed Forces, has rightly labelled “friends with benefits.”

To withstand an increasingly volatile security environment, however, this cooperation should evolve from a basic agreement on military access into an integrated, self-sustaining defence ecosystem. Navigating this shift requires a strategy built across three pillars.

First, the two countries should secure their logistical, industrial, and technological underbelly. Regional defence cannot hinge on fragile, trans-Pacific supply lines vulnerable to disruption.

The priority should be to further operationalise the bilateral Security of Supply Arrangement, which allows the two partners to address unanticipated supply chain disruptions. The two countries should expand cooperative maintenance repair and overhaul capabilities within Singapore for premium US-procured platforms, including the F-35 fighter jet and the rotationally deployed P-8A Poseidon. Through the bilateral Critical and Emerging Technology Dialogue, the two countries should also pioneer manned-unmanned teaming, linking Singapore’s manned aircraft with US-developed uncrewed surface vessels and aerial drones. Deployed over critical choke points like the Malacca Strait, this automated web will deter grey-zone threats like dark-shipping data spoofing and seabed infrastructure sabotage.

This integration should expand to cyber defence. By connecting Singapore’s civil (Cyber Security Agency) and military (Digital Intelligence Service) bodies with their US counterparts, such as the Cybersecurity and Infrastructure Security Agency and US Cyber Command, the two countries can strengthen their cyber cooperation. Concurrently, the US government should share actionable cyber threat intelligence and defensive playbooks with Singapore to safeguard critical domestic infrastructure and guarantee that regional maritime data ports and energy grids remain operational under the stress of a sophisticated, state-sponsored cyber offensive.

Beyond cyber, the partnership should operationalise the 123 civil nuclear agreement, which provides a framework for peaceful nuclear cooperation. With US government support for exporting and licensing US reactor designs in the future, the collaboration will ensure Singapore’s long-term energy security and strategic resilience.

Second, the partnership should transition from exclusive bilateralism to a networked regional model. Security in Southeast Asia cannot exist in isolation, nor can it be sustained by forcing countries into polarising, zero-sum alliances.

Singapore’s longstanding focus with self-reliance positions it well to thrive in Washington’s transactional era.

Singapore should leverage its position to embed US capabilities into a broader, inclusive regional framework that reinforces the centrality of ASEAN. Doing so means expanding functional, multi-nation minilateralism rather than rigid blocs. Singapore and the US should champion joint maritime law enforcement, counter-piracy, and humanitarian disaster-relief initiatives that include other Southeast Asian countries.

By deepening the integration of Washington’s maritime assets into regional information fusion centres — such as the Republic of Singapore Navy’s Information Fusion Centre — the partnership can also further enhance regional maritime domain awareness. This collaborative approach effectively counters transnational threats like illegal fishing and smuggling while quietly dampening great-power rivalries.

Third, both capitals should cultivate a new generation of strategic thinkers and doers. A relationship built purely on military hardware will atrophy if the human tissue connecting Singapore and Washington erodes. A new cohort of tech innovators, military officers, and diplomats is rising to prominence in a fragmented world, often detached from the shared historical context that forged the post-Cold War alignment.

The Singapore-US Summer Exchange Scholarship should be transformed into a defence-technology fellowship programme. Rather than exchanging conventional infantry officers, this initiative should embed Singaporean defence engineers into US defence-innovation hubs, and vice versa. Such a move will institutionalise a cohort of leaders. These future leaders will not only understand the rapid deployment of frontier software but also possess the sophisticated diplomatic vocabulary required to manage ties with other major powers, ensuring that deterrence is balanced with the open communication channels needed to manage crises.

Singapore’s longstanding focus with self-reliance positions it well to thrive in Washington’s transactional era. Moving the partnership beyond a legacy model of military access is not just about upgrading bilateral logistics; it is a test case for whether decentralised, capable networks can stabilise an increasingly fragmented Indo-Pacific. By demonstrating that a small country can combine sovereign high-tech deterrence with a commitment to regional neutrality and inclusive diplomacy, Singapore can redefine what a modern partnership looks like. This baseline will also show that a self-sustaining, technologically advanced capability is Southeast Asia’s best insurance policy against miscalculation and conflict.
