Soviet Explosive Ordnance - 122mm Projectiles (Part 2)

 

Soviet Explosive Ordnance



 

122mm Complete Round, Separate (Cartridge Case) Loading, CP, VG-471

 

 

This concrete-piercing round is fired from the 122mm corps guns M1931 and M1931/37 (A-19), and from the self-propelled guns M1944 (D-25S) and M1931/44 (A-19S).  The M1944 (D-25S) and M1931/44 (A-19S) are mounted in the JSU-122.
 

This round is used primarily against concrete and reinforced-concrete fortifications.  The projectiles are made of heat-treated steel and contain a bursting charge weighing from 7 to 18 percent of the total projectile weight.

 
The KTD-2 fuze is used in this round.  For purposes of illustration, the fuze nomenclature is shown on the side of the fuze; in reality, it is stamped on the base of the fuze.

122mm Complete Round, Separate (Cartridge Case) Loading, Smoke, VD-462

  

 

  

This smoke round is fired from the 122mm howitzers M1910 and M1909/37.  These weapons are obsolete in the Soviet Army but are still used in Finland.

  

Smoke rounds are used by the Soviets for denying observation to enemy firing points and observation posts, for laying wide smoke screens over entire sectors, for target spotting, and for other purposes. 

The common smoke compositions used in Soviet smoke rounds are phosphorus, sulfur trioxide, and chloride of tin.  Although the principal purpose of phosphorus is to produce smoke, it is an incendiary and casualty-producing agent as well.  It ignites spontaneously upon contact with the air and continues to burn even when embedded in the flesh.
 

The D-462 projectile in this round contains a 2.6kg (8 lb) phosphorus composition and a small TNT bursting charge.

  

The KT-2 and KTM-2 fuzes are used with the D-462 projectile in this round.  Information on color markings of smoke rounds is conflicting and outdated; however, it is believed smoke projectiles have a gray body and a black band below the bourrelet, as illustrated.

Caliber: 121.9mm (4.8 in)

Weight of complete round: 24.6kg (54.12 lbs)

Packaging

 

 

This ammunition is packed in a two-round wooden box.  Projectiles and cartriddge cases are also packed separately, 3 projectiles or 20 cartridge cases to a wooden box.
 

Note.  The first propellant data line "4/1 CB 10/44 K" shown on the cartridge case of this round normally would appear just above the second propellant data line on the packing box.  It has been omitted in the above drawing because of insufficient space.

 

 

 

 

 

 

122mm Complete Round, Separate (Cartridge Case) Loading, Illuminating, VS-463

 

This illuminating round is fired from the 122mm howitzer M1938 (M-30), which is standard in the Soviet and Satellite Armies.  The weapon is also used in Yugoslavia, Hungary, Rumania, Finland, and Bulgaria.

 

Illuminating rounds are used at night to facilitate observation of the enemy and of the results of firing.  They were employed comparatively seldom in World War II, since illuminating devices dropped from aircraft served the same purpose more effectively.  Mixtures of powdered magnesium, aluminium, and barium nitrate are used in the illuminating composition.
 

The S-462 projectile shown above contains an illuminant assembly attached to a parachute, a small expelling charge, and an ignition charge (to ignite the illuminant and the expelling charge).

 

The T-6 fuze, with adapter, is used with the S-462 projectile in this round.

Note.  Two propellant data lines normally appear on the cartridge case shown above, one line usually pertaining to powder in the base charge, and the other line pertaining to powder in the supplemental charges.

 

 

 

Characteristics

Caliber: 121.9mm (4.8 in)

Weight of complete round: 24kg (53 lbs)

Weight of projectile, as fired: 21.3kg (46.3 lbs)

Weight of propellant, w/o igniter: 2.07kg (4.58 lbs)

Type of projectile filler: Illuminating composition and explosive

Weight of projectile filler: 0.1kg (0.22 lbs)

 

 

 

Packaging

 

 

The illustrated 2-round wooden packing box weighs 68kg (150 lbs) when packed.  The gross weight may be stenciled on the box in the form БРУТТО 68 КГ.  Projectiles and cartridge cases are also packed separately, 3 projectiles or 20 cartridge cases to a wooden box.

 

 

 

 

 

 

122mm Complete Round, Separate (Cartridge Case) Loading, Shrapnel, VSh-462

   

 

This ball shrapnel round is fired from the 122mm howitzers M1910/30 and M1909/37.  These weapons are obsolete in the Soviet Army but are still used in Finland.

 

Shrapnel normally is used for close defense, against exposed personnel.  The Sh-360 projectile in this round contains an 8.75kg (19.25 lbs) shrapnel filler, consisting of 478 lead balls, and a small bursting charge of fine-grained black powder.
 

The 45-sec and T-6 (with adapter) fuzes are used with the Sh-460 projectile.  A light metal safety cap is crimped onto the 45-sec fuze for shipping purposes, and must be removed before firing.  The T-6 fuze has a threaded brass shipping cover which must be removed before firing.
 

The VSh-462T, with a Sh-460T projectile using a 45-sec or T-6 (with adapter fuze), is a variant of the illustrated round.  It is basically the same as the VSh-462 and is fired from the same weapons.

Note. The first propellant data line "7/7 CB 19/40 K" shown on the cartridge case of this round normally would appear just above the second propellant data line on the packing box. It has been omitted in the above drawing because of insufficient space.

 

  

  

 

 

 

122mm Complete Round, Separate (Cartridge Case) Loading, Propaganda, VA-463

 

   

This propaganda round is fired from the 122mm howitzer M1938 (M-30), which is standard in the Soviet and in Satellite Armies.

 

This type of ammunition is used to dsitribute propaganda leaflets behind enemy lins.  Very few such rounds were used in World War II, since aircraft proved to be a more effective means of distributing leaflets. m The A-462 projectile shown above contains a 0.76kg (1.67 lb) leaflet filler and a small bursting charge.

 

The T-6 fuze, with adapter, is used with the A-462 projectile in this round.
