Overview
Military equipment loss tracking through open-source intelligence has produced the most reliable publicly available data on material attrition in the Russia-Ukraine war. The Oryx project, founded by Dutch analysts Stijn Mitzer and Joost Oliemans, pioneered the methodology of visually confirmed loss tracking — requiring photographic or video evidence of each individual equipment casualty before inclusion in their database.
This methodology has set the gold standard for conflict data analysis and has been cited by governments, think tanks, and academic researchers worldwide.
Methodology
- Visual confirmation requirement: Every loss entry requires a photograph or video showing the damaged, destroyed, abandoned, or captured equipment. Claims without visual evidence are not counted, regardless of source
- Categorization: Losses are classified as destroyed (burned/detonated), damaged (visible combat damage but potentially repairable), abandoned (left behind intact), and captured (taken by the opposing force)
- Identification: Equipment types are identified to specific variant level (e.g., T-72B3 obr. 2016, not simply T-72), enabling nuanced analysis of which equipment types suffer highest attrition
- Conservative methodology: The inherent limitation is that many losses occur without documentation — destroyed vehicles in contested areas may never be photographed. Oryx figures are therefore understood as the minimum confirmed floor, not a complete count
Key Findings Through 2026
- Russia has suffered visually confirmed losses of 3,500+ tanks, 7,000+ armored vehicles, 1,000+ artillery systems, 400+ aircraft (fixed and rotary wing), and major naval vessels including the Moskva cruiser
- Ukraine's visually confirmed losses are lower but significant, reflecting both lower equipment quantities and different operational patterns
- Russian losses include large numbers of modern equipment (T-90M, Ka-52, Su-34, Pantsir-S1) that challenges Russia's replacement capacity
- Loss rate analysis reveals periods of intense attrition correlating with offensive operations — Bakhmut, Avdiivka, and Pokrovsk directions showing highest vehicle loss densities
- Community contributors expanded beyond Oryx to include WarSpotting, UALosses, and other projects using similar methodology
Strategic Implications
Equipment loss data provides irreplaceable insight into the war's material dimension. The confirmed destruction of thousands of tanks and armored vehicles demonstrates the attritional nature of the conflict and quantifies Russia's equipment exhaustion — increasingly relying on Soviet-era reserves (T-62, T-55) as modern production cannot match loss rates.
For Western defense planners, Ukrainian equipment loss data provides real-world validation of weapon system effectiveness and survivability that peacetime testing cannot replicate.
