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:
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
