What did the 28 May 2025 document leak reveal?
Summary
A look back at a day when a large trove of Russian procurement records surfaced, days after Berlin's announcement on long-range weapons.
What did a public database for contractors give away on 28 May 2025? Quite a lot, according to reports at the time: more than two million documents related to Russian military procurement were published that day.
The material included information on the modernisation and build-up of the Russian Strategic Missile Forces, the military base at Yasny, and the Avangard hypersonic glide vehicle. The source was a database meant for contractors, not a classified archive.
The backdrop
Two days earlier, on 26 May 2025, German chancellor Friedrich Merz announced that Germany and several other NATO allies had lifted all restrictions on Ukraine using long-range weaponry inside Russia. Kremlin Press Secretary Dmitry Peskov responded that the decision ran contrary to efforts to reach a political settlement to end the war.
The two items were separate reports. They nonetheless sat side by side in the news cycle: one concerned what Ukraine would be allowed to strike, the other concerned the procurement paper trail behind some of Russia's most prominent strategic programmes.
For readers looking back, 28 May 2025 is a reminder that the war was followed not only on the battlefield and in capitals, but also in contracting records that were openly accessible.
