The introduction of missiles leaves room for capable medium guns. The 3-inch/70 example can depress to minus 15 degrees and elevate to 90 degrees, allowing engagement from low approaches to almost overhead. Its quoted reach is 19,500 yards, close to eighteen kilometres, with a stated ceiling of 38,000 feet. That reach and elevation allow the gun to remain part of a defence increasingly equipped with guided missiles.
