Big Twist: Russia Urgently Wants S-400 Back from Turkey

In a surprising geopolitical twist, reports from Turkish and international media suggest that Russia has approached Turkey with a proposal to repurchase the S-400 air defense missile systems it originally sold to Ankara.

The story, first published by Turkish newspaper Nefes on September 13, 2025, has since been covered by outlets including Newsweek and Forbes.

According to the reports, Moscow’s interest is driven by a shortage of advanced systems amid high battlefield losses in Ukraine and increasing global demand. Russia currently lacks reserve S-400 units beyond those in active service, making it difficult to fulfill export commitments.

Deliveries to major clients such as India have already been delayed to 2026–27, with Algeria also likely to face postponements. Reacquiring the Turkish units could allow Russia to redeploy the systems directly or refurbish them for resale, preserving its position as a leading arms exporter.

Turkey initially purchased two S-400 batteries in a $2.5 billion deal signed in 2017, with deliveries completed in 2019. The decision was motivated by delays in acquiring U.S. Patriot systems and Ankara’s desire for greater air defense independence.

However, the move strained relations with NATO, as the Russian-made S-400s are incompatible with NATO infrastructure. In 2020, the U.S. imposed CAATSA sanctions and expelled Turkey from the F-35 program, where Ankara had planned to buy 100 aircraft.

Today, the S-400s remain largely unintegrated in Turkey due to interoperability issues, rising maintenance costs, political pressure, and a system shelf life already half-expired. Meanwhile, Turkey has accelerated development of its indigenous Steel Dome network, showcased at recent defense expos as part of Ankara’s bid to reduce reliance on foreign technology.

Reports suggest that Ankara could view Russia’s buyback offer as an opportunity. Offloading the S-400s might ease U.S. sanctions, facilitate long-sought F-16 upgrades, and even reopen doors to the F-35 program. For Turkey, the move could signal a reset in relations with Washington while reinforcing its domestic defense ambitions.

For Russia, reacquiring the S-400s would address immediate operational shortages but also highlight vulnerabilities in its defense industry—especially as Ukrainian strikes have destroyed S-400 batteries in Crimea.

Geopolitically, the buyback could fuel Western concerns that a NATO member is indirectly assisting Russia during the ongoing Ukraine conflict, sharpening scrutiny in Washington and other capitals.

This development also comes against the backdrop of Russia delaying S-400 deliveries to India and discussing possible deployments in Syria.

Analysts have called the potential arrangement an “insane geopolitical twist,” where a NATO ally might resell cutting-edge weapons back to Moscow. For Russia, it could be a tactical victory; for Turkey, it might pave the way for stronger ties with the U.S. and greater reliance on homegrown defense solutions.
