The 100 mm D-10 is a Soviet rifled gun family developed for armored-vehicle use at the end of the Second World War. Its D-10S form armed the SU-100 tank destroyer, while D-10T, D-10TG, and D-10T2S tank-gun variants became the main armament of T-54/T-55-family tanks and related foreign designs. This record is relationship-only because the available sources support platform installation and service history, not independent conflict-use rows for the gun separate from its carrier vehicles.
The D-10 was a vehicle-mounted 100 mm gun family rather than a single standalone weapon configuration. Sources describe a manually loaded, single-piece ammunition system with a horizontal sliding breech and hydraulic recoil equipment, then separate the early casemate D-10S from tank-gun D-10T-family versions.
100 x 695 mmR fixed ammunition with anti-armor and high-explosive options reported across D-10-family service.
Weaponsystems.net and the D-10 baseline reference both identify fixed 100 mm ammunition rather than separate-loading artillery rounds.
D-10S was tied to the SU-100 casemate mount, while D-10T-family variants were adapted for turreted tanks and stabilizer packages.
This is why the catalog links the gun to platform pages instead of inheriting platform conflict rows.
The D-10 designation covers related Soviet vehicle guns rather than one installation: D-10S denotes the SU-100 casemate gun, while D-10T-family marks identify tank-gun versions for T-54/T-55-family turrets.
| Variant | Configuration | Designation notes |
|---|---|---|
| D-10S | SU-100 casemate gun | Vehicle-mounted self-propelled anti-tank gun variant without a muzzle brake or bore evacuator, identified with GRAU index 52-PS-412. Sources: 100mm D-10 |
| D-10T | Early T-54 tank gun | Production tank-gun form introduced for early T-54 models, reported with GRAU index 52-PT-412 and no bore evacuator on the earliest production variant. Sources: 100mm D-10 |
| D-10TG | Stabilized T-54A gun | Variant for the STP-1 Gorizont single-plane stabilizer on the T-54A, with a bore evacuator near the muzzle. Sources: 100mm D-10 |
| D-10T2S | Two-plane-stabilized T-54B/T-55 gun | Variant for the STP-2 Tsyklon two-plane stabilizer used on T-54B, T-55, and later upgraded T-55-family tanks; 1980s upgrade programs added thermal sleeves on some installations. Sources: 100mm D-10 |
The D-10 page is treated as a gun-family component record; vehicle conflict pages should carry the conflict-use rows unless a source directly documents the gun as the conflict-use subject.
