Which range is achieved with Excalibur rounds for the M777 155mm howitzer?

• A. 40 km
• B. 24 km
• C. 30 km
• D. 48 km

Answer: (A)

Excalibur is a GPS-guided 155mm round that uses in-flight corrections to control its trajectory and compensate for wind, air density, and other factors. From the M777, this guidance lets the projectile travel farther than standard unguided rounds while still hitting precisely where you need it. With typical propellant charges, the practical range of Excalibur from the M777 is about forty kilometers. Unguided rounds from the same gun don’t reach that far, usually in the mid-20s to around 30 km, and pushing toward 48 km would require different, higher-energy options. So the best fit for the range achieved with Excalibur rounds is about forty kilometers.
