Russia unveiled the Su-75 Checkmate in 2021 as a low-cost, export-friendly stealth rival to the F-35, promising modern sensors, stealth capabilities, and mass production. Four years later, it remains mostly a marketing prop—a fighter jet program that can’t seem to get off the ground, let alone land successfully.

The Flashy Rollout

Unveiled with Hollywood-like fanfare at MAKS 2021 with President Vladimir Putin in attendance, the Su-75 Checkmate was presented as Moscow’s answer to the F-35—a capability sweet spot of stealth, sensor fusion, and exportability that would give Russia a chance to break out of its growing isolation in the global arms market.

The single-engine, fifth-generation stealth fighter was marketed at an ambitious price point of $25-30 million per aircraft, designed to attract customers who wanted advanced capabilities without the cost or political complications of Western fighters.

Well over four years later, and now deep into 2025, Checkmate remains resolutely notional—more brochure than aircraft, despite recent announcements of a prototype scheduled to fly “next year.”

What Went Wrong

The problem is not lack of trying. Russia’s military-industrial base has been ground down by sanctions, cannibalized for the Ukraine war, and strained to its limits by competing demands of mobilization, equipping new formations, and keeping the war effort going.

The war in Ukraine has consumed Russian aerospace capacity. Resources once earmarked for advanced platforms are now being used to keep an aging Soviet-era fleet in the air. Factories that might once have been poised for next-generation work are busy churning out upgrades of Soviet-era designs and a trickle of Su-57s, not prototypes of an all-new stealth fighter.

A country forced to scrounge for routine microelectronics and machining equipment via complex sanctions-evasion networks is, in no meaningful sense, primed to introduce a next-generation fighter.

Repeated Delays

Test flights have been repeatedly delayed. The first flight was initially promised for 2023, then pushed to 2024, and now projected for 2025 or later. Two prototypes are reportedly scheduled for assembly in 2025 according to the director of Komsomolsk-on-Amur Aircraft Plant, but many analysts remain skeptical.

Even if some form of airframe does take to the sky, taking that prototype to serial production would require industrial scale that Russia currently lacks. The country is already struggling to produce advanced fighters, delivering only a few Su-57 units per year.

The T-14 Armata Problem

The Su-75 increasingly resembles another Russian military program: the T-14 Armata tank. Both featured flashy rollouts with significant media attention, bold claims about revolutionizing their respective domains, and promises of mass production. Both remain largely absent from actual combat operations despite years of development.

With no firm export orders, no proven flying prototype, and no realistic production capacity, the Su-75 has landed in the same twilight zone as the Armata—nominally real but operationally irrelevant, a strategic dead end.

Export Markets Won’t Save It

The notion persists that Russia could revive the Su-75 with help from export customers. The reality is that there are no firm export orders for a plane that is not flying.

Any nation that might have been tempted—India, Vietnam, the UAE—is now keenly aware of Russia’s manufacturing constraints and technology gaps. They have seen the performance of Russian aircraft over Ukraine and formed their own conclusions. Potential partners like India and the UAE have both turned down participation in the program.

Advanced fighter procurement is not just about upfront price. It is about long-term sustainment, software sovereignty, and industrial partnership. Why would any state want to tie itself to an airframe that Russia cannot support in wartime and cannot produce in peacetime?

Russia’s Real Priorities

If there is a genuine Russian innovation story to emerge from the war, it has little to do with next-generation fighters and everything to do with drones, electronic warfare, and mass production of cheaper munitions.

Moscow has doubled down on the logic of attrition: saturate, exhaust, and overwhelm. It is not a world in which a boutique stealth aircraft has much chance to succeed. It is a world in which swarming UAVs, loitering munitions, and ad-hoc battlefield networks define the air domain.

Viewed through that lens, the Su-75 is not just a stalled program—it is a relic of pre-war thinking, a vision of high-end airpower at exactly the moment that Russia is pivoting toward the low-cost, high-volume paradigm that the war in Ukraine has forced upon it.

A Program Trapped in Limbo

The Su-75 is trapped in a strategic dead end: too expensive and too ambitious to cancel outright, too unrealistic to actually manifest. What remains is an object lesson in political signaling—a plane meant to project modernity, competence, and intent.

Russia simply lacks the supply chains, technological depth, and industrial capacity to field a fifth-generation export fighter at scale in this decade. Anything approaching a robust global Su-75 fleet in the 2030s belongs more to the marketing brief than to reality.

The Perfect Allegory

The Su-75 is the perfect allegory for post-Ukraine Russia: bold on paper, brittle in practice, and trapped in a strategic landscape that penalizes illusion. The plane may still make appearances at airshows and exhibitions for years to come, but its real role has already been revealed—not as a fighter that will dominate the skies, but as a symbol of ambitions that exceed capabilities.

In the end, the Su-75 Checkmate is a fighter that can’t land because it never truly took off.
