Forecast International lists OE 90 F1 under Nexter Munitions and the related Luchaire line, while ordnance references identify the full French cartridge label and explosive weight. The record remains relationship-only because the consulted sources support ammunition identity and firing-gun compatibility, not exact-round use in a named conflict.

Specialist references trace the gun to the earlier M621 mechanism but a larger 20x139 mm NATO cartridge, dual-belt feed, and about 900 rounds per minute. The catalog keeps it as a relationship-only component page because public sources most clearly document the M693 through host platforms and derivatives: AMX-10P vehicles, naval 20F2 mounts, Narwhal 20B turrets, and the South African GI2 production variant.
