Vyrivniuvach

Ukraine's first domestically produced guided glide bomb — a clamp-on wing module plus a guidance tail that converts a standard 250-kg bomb into a satellite-guided stand-off weapon. It is Ukraine's answer to the Russian FAB-UMPK glide bombs that have flattened front-line towns. Declared "combat-ready" in May 2026, it has no confirmed combat strike on the record yet, and most of its figures are maker claims.

Overview

The Vyrivniuvach (Вирівнювач — "Equalizer" or "Leveler") is Ukraine's first home-built precision-guided glide bomb, developed by DG Industry through the state Brave1 defense accelerator. Crucially it is a conversion kit, not a standalone munition: a wing module that clamps onto an existing bomb plus a guidance tail that replaces the fins — the same architecture as Russia's FAB-UMPK and the US JDAM-ER, which is exactly the point. Defence Minister Mykhailo Fedorov declared it combat-ready on 18 May 2026 after roughly 17 months of development, and it had its detailed public/export debut at Eurosatory 2026 in Paris in mid-June. A hard caveat frames the figures below: despite a healthy outlet count, the facts are almost entirely single-origin (the 18 May Brave1/DG announcement plus Eurosatory placards), there is no government datasheet, no test telemetry, no CEP and no confirmed combat use.

Development

Russia's glide bombs have been one of the war's most punishing weapons — fired in the thousands per month from stand-off range against which Ukraine had no symmetric reply — and the Vyrivniuvach is the explicit attempt to "equalize" that. DG Industry developed it via Brave1 over a stated ~17 months (officially begun around December 2024), and Fedorov announced combat-readiness on 18 May 2026, with an experimental first batch ordered and delivered to the Air Force. The "built from scratch, not a copy" framing is a manufacturer claim; the kit follows the established JDAM-ER/KGK pattern, with its one cited differentiator being a distinct control-surface layout (stabilizers plus smaller fins rather than fully rotating tail fins).
