| ARMY PROJECTILES |
| Type 2 - 7-cm (75-mm) Hollow-Charge Projectile |
| Weight of projectile, filled (without fuze): 3.56 kg. (7.81 pounds). |
| Weight of filling: 0.50 kg. (1.11 pounds). |
|
Filling: A cast mixture of 60 percent TNT and 40 percent cyclonite (RDX) wrapped in varnished paper. |
| Diameter at bourrelet: 75.0 mm (minus tol.). |
| Length over all (without fuze): 240.0 mm (9 1/2 inches). |
| Length protruding from case: 210 mm (8 1/4 inches). |
| Length of projectile body (without nose cap): 183.0 mm (7 3/16 inches). |
| Width of rotating band: 10.0 mm. |
| Fuzing: Type 88 instantaneous (gun type). |
|
Operation and Employment: This round is used principally as an antitank weapon. In firing tests it penetrated 3 inches of Navy hull plate (Headquarters USAFISPA, Office of the A.C. of S., G-2 Ordnance Intelligence Unit Report No. 41, entitled "Firing Tests of Japa-nese Antitank Weapons"). |
| Weapons in which used: |
|
Type 94 mountain gun: Case, 11 9/16 inches. |
|
Type 41 mountain gun: Case, 7 1/4 inches. |
|
Remarks: 1. There is a marked similarity between this projectile and German hollow-charge rounds, both in projectile design and in explosive filling. |
|
2. The symbol TA stenciled on this projectile is employed in other Japanese munitions to indicate hollow-charge design. |
|
3. In the earliest rounds found, the projectiles were marked by a yellow band around the middle of the body, indicating "High-Explosive" according to the new color system. Later recoveries indicate the adoption of the combination of white band, used to indicate "Armor-Piercing," together with the yellow band. Both bands appear near the middle of the body. This arrangement is not to be confused with the use, in the old color system, of a yellow band above a white band for marking "High-Explosive" projectiles. |
