For sixty years, the answer to the question “what does Vietnam fly?” has been simple: whatever Moscow sold it. MiGs, then Sukhois — a proud, entirely Russian air force. In 2026, for the first time, that answer is genuinely in doubt, and the alternative wears a French accent.

Hanoi is hunting for a new fighter, and the contest has narrowed to two very different machines: the Dassault Rafale and the Sukhoi Su-57. On paper it looks like a procurement decision. In practice it is one of the most revealing strategic choices in Southeast Asia — because in choosing a jet, Vietnam is also choosing a side.

The pressure is not abstract. Across the South China Sea, China now flies J-16 strike fighters and J-20 stealth jets over waters Vietnam considers its own. Against that, Hanoi’s ageing Su-22s and Su-27s look every one of their years.

The Rafale: the fast, Western answer

The clearest sign that France is serious is a small but telling detail: a Vietnamese pilot has reportedly been allowed to fly the Rafale. That kind of access is normally reserved for customers deep in negotiation, not polite first dates. French reporting in early 2026 put the talks at an unusually advanced stage.

What Paris is offering is a genuine omni-role fighter — an AESA radar, the formidable SPECTRA self-defence suite, long legs for maritime patrol, and a weapons load north of nine tonnes. Open-source estimates put a deal at roughly two squadrons, perhaps 24 to 40 aircraft, for US$4–6 billion, with first jets conceivably arriving between 2028 and 2030.

There is precedent for the politics. Indonesia’s 42-Rafale order showed that a Southeast Asian state can buy French without burning its bridges to Moscow. For Vietnam, the Rafale is as much a diplomatic instrument as a fighter — a way to widen its circle of friends in an era when relying on a single, sanctioned supplier looks dangerous.

The Su-57: the comfortable, Russian answer

And yet Russia is not out of the running. Hanoi has eyed the Su-57 since at least 2017, and interest persisted into April 2026, with attention focused on the upgraded Su-57M1 expected to mature early in the next decade. Its appeal is continuity: the jet would plug straight into the ecosystem Vietnam already runs — the Su-30 fleet, the S-300 air defences, the doctrine, the muscle memory.

The catch is everything that now hangs over Russian arms exports: questions about production rates, delivery timelines, sanctions exposure and whether the Su-57 line can actually meet Vietnam’s deadlines. A stealth fighter that arrives late is no deterrent at all.

Why the answer may be “both”

The most likely outcome is the least dramatic one. Rather than crown a single winner, Hanoi may do what New Delhi did — build a mixed fleet. Rafales would replace the oldest Su-22s in the near term; the upgraded Su-30MK2s would stay as the numerical backbone; and a small batch of Su-57s could arrive later as a high-end stealth insurance policy.

It is a very Vietnamese solution: hedge, diversify, commit to no one entirely. The danger is that the South China Sea will not wait politely while Hanoi deliberates. In a contest measured in sensor range and stealth, indecision has its own price — and the clock over those contested waters is already running.
