A World War I-era cannon first fired by Marines more than 90 years ago to commemorate the opening of the Naval Surface Warfare Center in Dahlgren, Va., was returned to the center in July, on loan for the next decade from the National Museum of the Marine Corps.
The detachment of Marines fired the seven-inch tractor-mounted behemoth Oct. 16, 1918, a Navy release said. It’s been returned to the Navy proving ground in anticipation of the facility’s 100th anniversary.
On the day the installation was founded, the Marines launched a 152-pound projectile about 24,000 yards down the Potomac River. Army observers later described the weapon as, “the heaviest and hardest hitting gun for which a mobile field mount of this kind had ever been requested by any nation or army.”
Its range — between 19,000 and 25,000 yards — was more than double that of its predecessors.
