The MK38 gun system max effective range is what distance?

• A. Engage target at 1,900 yards
• B. Engage target at 2,500 yards
• C. Engage target at 3,100 yards
• D. Engage target at 2,700 yards

Answer: (D)

Max effective range is the distance at which the weapon can reliably hit a target with its standard ammunition and fire-control under normal conditions. For the MK38 25mm gun system, the reliable hit capability with typical rounds and shipboard fire-control extends to about 2,700 yards. At shorter ranges you can still engage successfully, but 2,700 yards represents the farthest distance at which hits can be expected with the system as configured. A distance like 3,100 yards exceeds this reliable range, while 1,900 or 2,500 yards are within range but not the maximum. Therefore, 2,700 yards is the best match for the max effective range.
