The 122 mm M-62T2, indexed as 2A17, was the late Soviet rifled tank gun developed for the T-10M heavy tank. It replaced the D-25T/D-25TA line in the final Soviet heavy-tank modernization, adding higher-velocity ammunition, a multislotted muzzle brake, bore evacuation, manual separate loading, and integration with the T-10M's two-plane stabilizer and T2S-29-14 sight package.

Gun Features

Public reference data describes the M-62T2 as a manually loaded rifled 122 mm gun with separate-loading ammunition, a semiautomatic horizontal sliding-wedge breech, a multislotted muzzle brake, and hydraulic/hydropneumatic recoil equipment.

Ammunition format

Weaponsystems.net lists 122 mm separate-loading shells and gives representative velocities for BR-472, BM-11 APFSDS, and OF-472 ammunition.

Fire-control package

GlobalSecurity ties the T-10M installation to the T2S-29-14 sight and 2E12 Rain/Liven two-plane stabilizer.

Museum evidence

Commons media pages identify photographed 2A17 guns at the Motovilikha Plants museum in Perm, giving reusable image support for the standalone gun.

Variants

Open sources use M-62T2, M-62-T2, M62-T2S, and 2A17 for the same 122 mm gun family; the suffix and spacing vary by source rather than by a separately documented public production model.

VariantConfigurationDesignation notes
M-62T2 / 2A17T-10M production gun

Weaponsystems.net identifies 2A17 as the GRAU index for M-62T2 and describes it as the production T-10M armament.

Object 264 prototype installationExperimental T-10-series mount

GlobalSecurity describes a prototype installation of the new gun on experimental Object 264 in 1955 before the T-10M/Object 272 modernization.

Carrier Vehicle

The M-62T2 is linked to its documented production carrier without inheriting vehicle-level conflict history.

CarrierCarrier typeCarriage evidence
T-10M, Heavy tank, TanksT-10MSoviet heavy tank

The T-10M mounted the 122 mm M-62T2 / 2A17 as its main gun, with the installation described alongside the 2E12 two-plane stabilizer and T2S-29-14 sight package.

Conflict-use boundary

This gun page remains relationship-only because the reviewed sources did not provide a direct, in-scope post-1995 conflict-use record for the M-62T2 independent of its carrier.

Sources: Tankograd T-10

Carrier And Design Context

The M-62T2 is retained here as a sourced tank-gun component rather than as a separate battlefield vehicle. The reviewed sources identify the gun with the T-10M heavy tank, now linked as a carrier record, but do not provide direct in-scope post-1995 conflict-use evidence for the gun independent of that carrier.

Primary carrier

Weaponsystems.net, GlobalSecurity, and Tankograd identify the T-10M heavy tank as the production carrier for the 122 mm M-62T2 / 2A17 gun.

Modernization role

GlobalSecurity describes the M-62-T2 / 2A17 as the more serious T-10 modernization after the D-25T/D-25TS line, giving the T-10M improved ballistic characteristics and a new sight/stabilizer package.

Predecessor context

Weaponsystems.net treats the M-62T2 as the D-25T successor for heavy tanks, using the same 122 mm class while firing newer ammunition types at higher velocities and flatter trajectories.

Conflict-use scope

Some sources describe 1968 Operation Danube carrier context, but the catalog's normal new-conflict scope is post-1995. This relationship-only page therefore leaves conflicts and conflictUsage empty rather than inheriting older carrier-vehicle history.

Timeline

122 mm M-62T2 Key Events

  1. Development window opens

    Weaponsystems.net places M-62T2 development in the 1949-1955 period, tying the gun to No. 172 Motovilikha plant design work.

    Sources: Weaponsystems.net M-62T2

  2. Prototype gun and Object 264 context

    Weaponsystems.net lists three prototype guns in 1955, while GlobalSecurity notes a prototype installation on experimental Object 264.

    Sources: Weaponsystems.net M-62T2, GlobalSecurity T-10

  3. T-10M armament package

    GlobalSecurity describes the T-10M/Object 272 modernization as receiving the new M-62-T2 / 2A17 gun, T2S-29-14 sight, and 2E12 two-plane stabilizer.

    Sources: GlobalSecurity T-10

  4. Series-production period begins

    Weaponsystems.net gives 1957-1965 as the series-production period and lists No. 172 Motovilikha plant plus No. 221 Barrikady plant as producers.

    Sources: Weaponsystems.net M-62T2

  5. Production period closes

    Reference coverage places M-62T2 production ending around 1965 as the Soviet T-10 heavy-tank line gave way to main battle tank development.

D-25 122 mm tank gun, 122 mm tank and self-propelled gun family, ArtilleryArtilleryD-25 122 mm tank gun122 mm tank and self-propelled gun familyThe D-25 was a Soviet 122 mm gun family adapted from A-19-line ballistics for heavy tanks and self-propelled guns. D-25T armed the wartime IS-2 heavy tank and later IS-series vehicles, with directly sourced use on Soviet IS-2s in the Second World War, Egyptian IS-3M tanks in the 1967 Six-Day War, and captured Israeli IS-3 fixed bunkers in the 1969 War of Attrition. D-25S was the semi-automatic self-propelled-gun variant associated with ISU-122S, and the family used separate-loading A-19/D-25 ammunition including OF-471 high-explosive fragmentation and BR-471 armor-piercing projectiles.

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.

F. Petrov and adopted in 1937. It combined a 152.4 mm barrel, split-trail carriage, large muzzle brake, separate-loading ammunition, and a 17.2 km high-explosive range in a weapon built for corps and army artillery. Its modern catalog relevance comes from residual stock use: Ukrainian reporting in October 2025 documented Russian forces towing and losing an ML-20 in Donetsk region during the 2014 Russia-Ukraine War.
