Ammunition Types
The S-60 fires ammunition in 57x348SR caliber, a cartridge noticeably weaker than the 57mm ammunition of either Bofors 57mm AA gun, or Soviet 57 anti-tank guns of World War II. Modern anti-aircraft rounds have not been developed for the gun - the main characteristics of the Soviet-era ammunition is listed in the table below. In addition to these People's Republic of China manufactures ammunition in 57x348SR caliber, designated Type 59 HE-T, Type 59 AP-T, and Type 76 HE-T.
Training rounds include a blank round MK-281 ("Manöver-Kartusche", East German designation), and training rounds with -IN suffix (UBR-281U-IN, UOR-281U-IN) identifying the rounds as fuzeless versions of the APCBC and HE rounds with dummy fuzes and inert filling replacing the explosive cavities.
| Designation | Type | Projectile Weight | Bursting charge | Muzzle Velocity | Description |
|---|---|---|---|---|---|
| UBR-281/281U | APCBC-T | 2820 | 13 | 1000 | Anti-tank round with sharp penetrator, blunt cap and an aerodynamic cover, with tracer and a delayed-action base fuze. Penetration 96 mm RHA at 1000 m range or 106mm at 500m. UBR-281 and -281U are loaded with the same projectile and differ only by details in case mouth and swage grooves. |
| UOR-281 | HE-T | 2850 | 154 | 1000 | Impact-fuzed fragmentation shell for anti-aircraft use. Nose fuze with self-destruct function and a tracer. |
| UOR-281U | HE-T | 2850 | 154 168 |
1000 | Similar to UOR-281; some sources state the shell is the same as in UOR-281 and the round differs from it only in details of the case mouth and swage grooves (as with the UBR round), while others claim a slightly larger HE filling. |
| Type 59 AP | AP-T | ? | ? | ? | Chinese anti-tank round presumably similar to UBR-281/281U. |
| Type 59 HE | HE-T | ? | ? | ? | Chinese fragmentation round for anti-aircraft use, presumably similar to UOR-281/281U. |
| Type 76 HE | HE-T | ? | ? | ? | Chinese fragmentation round. |

Famous quotes containing the word types:
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
