 The SM-2-1 has access to three types of ammunition: OF-42 HE, PB-42 SAP and ZS-42R HE-VT. The OF-42 offers a very potent destructive effect against lightly armoured targets and a superior HE filler than the ZS-42R HE-VT. However, as most HE shells, it barely has the penetration to counter armour (just 37 mm of penetration at all ranges and angles). The PB-42 SAP offers a midpoint between APCBC and HE shells as it has a decent explosive filler with sufficient armour penetration (203 mm flat at 1,000 m). This round should be the main round utilized when fighting all type of ships due to the armour penetration. Lastly, the ZS-42R HE-VT round offers a superb explosive filler for AA purposes but is almost half of the explosive filler of the OF-42 HE. Since it has a proximity fuse, engaging aircraft is much easier.

-The SM-2-1 130 mm weapon system is the Soviet equivalent to the [[5 inch/38 Mk.12 (127 mm)|5 inch/38 Mk.12]] weapon system in terms of reliability, calibre, and use. This weapon system is completely new to the WW2 Soviet 130 mm cannons as it features an autoloader, enhanced targeting, and radar capabilities. As already seen in Soviet 130 mm cannons, they are multi-purpose weapon systems with devastating AA capabilities. However, compared to the Mk.12, it has a significantly reduced ROF (15 RPM vs 22 RPM) but it counters that with much faster targeting speeds and better cannon elevation angles.
