Separates ammunition is loaded in two parts: the projectile and the propellant charge are handled separately rather than as a single fixed round. This arrangement lets the crew adjust muzzle velocity and range by varying the amount of propellant used while keeping the same projectile. In 5-inch guns, this two-piece loading is common, which is why the description that the projectile is separated from the casing and that it’s used in 5" guns is true. The other ideas don’t fit: fixed ammunition combines projectile and propellant in one unit, the 3" caliber detail isn’t a defining feature of separated ammo, and propellant is still required to generate the firing pressure.
