WRT the diameter presented in the French OFL 120 G1 Sub-Projectile Length

I'm seeing a diameter of 26mm only, without a projectile length in the Sub-Projectile Length nor a coefficient to get a length, and the Penetrator Dimensions again only has a diameter. Is this projectile length unknown, or am I misunderstanding the notation? 2600:8807:A985:D900:F160:39BB:B3D5:8275 (talk) 19:44, 23 March 2023 (UTC)[reply]

The length of the OFL 120 G1 subprojectile (541.5 mm) and the diameter of its penetrator (26 mm) are published figures. The penetrator length is based on measurement estimates (I got 375 mm, thus a 14.4:1 ratio of length-to-diameter). FORMATOSE (talk) 14:34, 14 January 2024 (UTC)[reply]

Chinese 120mm gun?

What gun is used on the Type 89 (tank destroyer) and is it compatible with the NATO ammunition. FSbiran (talk) 12:57, 12 June 2023 (UTC)[reply]

I has never been specified that the PTZ-89's 120 mm gun was NATO-compatible.

Furthermore, the Chinese 120 gun has a lower operating pressure (400 MPa) and a chamber volume of 16 L, more than NATO 10.2 L FORMATOSE (talk) 21:55, 16 June 2023 (UTC)[reply]
