Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for 23mm Volkov-Yartsev, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

Size vs familiar rounds
Drawn at true 1:1 — every case is accurate relative to the others. Absolute size depends on your screen's pixel density, so measuring one against a real ruler may be off. 23mm Volkov-Yartsev is highlighted below.

History
Designed by Volkov and Yartsev to give Soviet ground-attack aircraft genuine anti-armor capability against German vehicles. The belted 23×152mmB case was powerful but the VYa-23 cannon was heavy; postwar Soviet designs moved to the lighter, faster-firing 23×115mm used in the NR-23 and GSh-23.
