Soviet Explosive Ordnance - 107mm Projectiles

 
 
107mm Artillery Projectiles
 
 
 
 
107mm Complete Round, Seperate (Cartridge Case) Loading, HE, VF-423
 
 
 
This high-explosive round is fired from the 107mm corps guns M1910/30 and M1940 (M-60).  These weapons are obsolete in the Soviet Army, but they may be found in service with Satellite armies.  This projectile has a relatively thin-walled casing and large bursting charge.  It gives a greater blast effect than the VOF-423, but less fragmentation.
  
The RGM (with supplementary booster), UGT, and UGT-2 fuzes are used with the F-422L projectile in this round.  The VF-423 complete round also may be found with an F-422M projectile using an RGM fuze.
 
The following complete rounds are variants of the VF-423 round: VF-423D, with the F-420U projectile using the UGT-2 fuze; and VF-423K, with the F-422L projectile and the 3GT fuze.  They are basically the same as the VF-423 and are fired from the same weapons.
 
Note.  The dimensions for the cartridge case in the above illustration have not been verified.

107mm Complete Round, Seperate (Cartridge Case) Loading, Frag-HE, VOF-423
 
   
This fragmentation high-explosive round is fired from the 107mm corps guns M1910/30 and M1940 (M-60).  These weapons are obsolete in the Soviet Army, but they may possibly be found in service with Satellite armies.  The illustrated round gives both fragmentation and blast effect.
 
The setting of the fuze determines whether the fragmentation or blast effect will be the greater in any given instance.  The projectile burst will produce from 300 to 400 lethal fragments.
 
The RGM and D-1 fuzes are used with the OF-420 projectile in this round.  The RGM fuze is used for impact fire or, with a delay setting, for ricochet fire.  The D-1 fuze is used exclusively for time fire.
 
The VOF-423U complete round, with an OF-420U projectile using a UGT-2 fuze, is a variant of the illustrated round.  It is basically the same as the VOF-423 and is fired from the same weapons.

107mm Complete Round, Seperate (Cartridge Case) Loading, Incendiary, VZ-423
 
   
This incendiary round is fired from the 107mm corps guns M1910/30 and M1940 (M-60). These weapons are obsolete in the Soviet Army, but they may possibly be found in service with Satellite armies.
 
Incendiary rounds are used to start fires in and behind enemy lines, in order to destroy wooden structures, fuel dumps, and ammunition supplies.  The Z-420 projectile shown above is loaded with 16 segments of either thermite or "electron", and a small explosive bursting charge.
 
The T-6 and T-7 fuzes are used with the Z-420 projectile of this round.  Both of these fuzes are provided with a brass cap (not shown in the above drawing).
 
 
 
Characteristics
Caliber: 106.7 (4.2 in)
Weight of complete round: 23.23kg (51.1 lbs)
Weight of projectile, as fired: 17.24kg (37.93 lbs)
Weight of propellant, w/o igniter: 2.79kg (6.14 lbs)
Type of projectile filler: Thermite (16 segments) and explosive
Weight of projectile filler: 1.604kg (3.53 lbs)
 
  
Packaging
 
   
This ammunition may be packed in a two-round wooden packing box, as illustrated, or in a four-round box.  Projectiles are also packed seperately, three to a wooden box.  Box measurements in the above illustration have not been verified.
 


 
 
107mm Complete Round, Seperate (Cartridge Case) Loading, Smoke, VD-423
 
   
This smoke round is fired from the 107mm corps guns M1910/30 and M1940 (M-60).  These weapons are obsolete in the Soviet Army, but may be found in service with Satellite armies.  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 use 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-422 projectile shown above contains a smoke composition and a black powder bursting charge.  The UGT-2 fze is used with the D-422 projectile in this round.  The D-422 projectile is a steel shell of an old model, and must be fired with a reduced charge.
 
The complete round VD-423U, with the D-422U projectile using the UGT-2 fuze, is a variant of the illustrated round.  It is basically the same as the VD-423 and is fired from the same weapons.

107 Complete Round, Seperate (Cartridge Case) Loading, Shrapnel, VSh-423
 
   
This ball shrapnel round is fired from the 107mm corps guns M1910/30 and M1940 (M-60). These weapons are obsolete in the Soviet Army, but may be found in service with Satellite armies.  Shrapnel rounds are used primarily against exposed personnel.  The Sh-422 projectile contains shrapnel balls of a lead and antimony composition, and a small bursting charge.
 
The 45-sec time fuze is used with the Sh-422 projectile in this round.  A light metal cap is crimped onto the 45-sec fuze for shipping and must be removed before firing.  The model designation may or may not be stamped on the fuze.
 
The complete round VSh-423T, using a Sh-422T projectile with the T-6 fuze, is a variant of the illustrated round.  It is basically the same as the VSh-423and is fired from the same weapon.
