Use this category to compare medium-calibre rounds by complete cartridge dimensions, not projectile diameter alone. The catalogue includes 20x102, 20x110, 20x110RB, 23x115, 23x152B, 30x165, 30x173, 40x311 and 40x365 mm families. Because 20 mm and 30 mm systems use different case lengths and rim configurations, every family keeps its full designation. High-explosive, armour-piercing, practice, blank, illuminating, smoke and other specialised line items remain separated rather than grouped under a generic calibre label.
The item page carries the available technical data, images and revisioned English datasheet. Platform compatibility is not inferred from calibre alone and must be confirmed against the stated weapon system, destination, quantity and end use. Standard labels are shown only when present in the source catalogue. Quotations are issued to government end-users and licensed entities subject to the applicable export licence, transaction review and verified End-User Certificate.
Forty-six line items carry a high-explosive nature. The designation families run 20 mm x 102, 20 mm x 110, 20 mm x 110RB, 23 mm x 115, 23 mm x 152B, 30 mm x 165, 30 mm x 173, 30 mm x 210B, 30 mm x 220, 37 mm x 252, 40 mm x 311, 40 mm x 365, 57 mm x 348 and 57 mm x 438, in plain HE, tracer HE-T, incendiary HEI, HEI-T and pre-fragmented PFHE suffixes. Every record states a projectile mass, a muzzle velocity and an operating temperature band; explosive mass and fuze figures appear where the source records them.

Nine line items cover the pyrotechnic natures held in this domain. The designation families are LP 57 for the 26.5 mm single-star signal cartridge and the MN-01, MN-01/P and MN-01-T marks for the 38 mm cartridges; the 25 mm flambeau, the 26.5 mm trip flare, the 38 mm signalling cartridge, the 38 mm muzzle blast cartridge and the 38 mm shock and flash cartridge are listed without a separate mark. Every record states a calibre and a cartridge mass, and the 38 mm marks add the mass of their pyrotechnic, signalling or active composition.
