 == General info ==
-The 45mm/89 SM-21-ZIF is a postwar Soviet 45mm naval autocannon mounting. It uses the same cannon as the SM-20-ZIF mount, but in a single mount rather than a quadruple mount. The simplest comparison to make is with the Swedish 40 mm Bofors gun: a hard-hitting, high velocity autocannon with a mediocre rate of fire.
+<!-- ''Tell us about the tactical and technical characteristics of the cannon or machine gun.'' -->
 === Available ammunition ===
-The SM-21-ZIF has one ammunition belt choice: alternating 45mm {{Annotation|HEF|High-Explosive Fragmentation}} and {{Annotation|HEF-T|High-Explosive Fragmentation Tracer}}. The tracer round, besides helping you aim, contains slightly more explosive filler: 54 grams A-IX-2 for the non-tracer round versus 60 grams A-IX-2 for the tracer round. Both rounds have a considerable amount of explosive power and have an excellent muzzle velocity of 1,080 m/s.
+<!-- ''Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).'' -->
 === Comparison with analogues ===
-[[Bofors (40 mm) (Family)]]: The ubiquitous Bofors 40 mm L/60 loses out to the SM-21-ZIF in terms of muzzle velocity and high explosive power. However, the L/60 gun has a better rate of fire and access to {{Annotation|AP|Armor Piercing}}ammunition. This allows it to engage targets with armor that is too strong for the SM-21-ZIF to damage effectively, such as the [[SF40 Light]]. Overall, they have the same practical effectiveness against light targets, but the SM-21-ZIF can generally be considered superior for most use cases.
+<!-- ''Give a comparative description of cannons/machine guns that have firepower equal to this weapon.'' -->
-On the other hand, the Bofors 40 mm L/70 (as found on [[Hugin]], for example) can generally be considered to be in the same class as, or even superior to, the SM-21-ZIF. Advantages of the L/70 gun include access to {{Annotation|HE-VT|High Explosive Variable Time}}ammunition, higher rate of fire, and overall having more explosive mass in both of its ammunition choices. The ZIF has comparable explosive effect with slightly higher velocity and is less prone to overheating, as well as being found at a much lower Battle Rating.

 == History ==
-This weapon was first designed in 1946 and was used in a number of experimental mountings made during 1946-50. The first was the SM-21 single gun mount made in 1947-48 and tested in 1949. This was found to be deficient in many areas and was cancelled. The requirements were then rewritten and a new design was produced accordingly. A prototype was completed by the end of 1950 and tested in 1951. This proved more successful and the mount was accepted into service in 1954. Additional designs for the SM-16 stabilized twin mount, the SM-17 unstablized twin mount plus others using this gun did not go into production.<ref>http://www.navweaps.com/Weapons/WNRussian_45mm-78_SM-7.php</ref>
