The Zalinski dynamite gun referred to a series of dynamite guns which were designed and built by American military engineer and inventor Edmund Zalinski. Only approximately 15 of these guns were built, 11 of which were known as the 15-inch Pneumatic Dynamite Guns. They were 15 in (38 cm) in diameter and were installed on a series of experimental[4] coastal artillery batteries initiated by the Endicott Board from 1894 to 1901.[5]
The dynamite guns were commissioned by the United States Department of War for the defense of the US's Atlantic and Pacific coasts. They were designed to throw explosive projectiles from 2,000 to 6,000 yd (1,800 to 5,500 m) depending on their weight. The projectiles, colloquially known as "aerial torpedoes," could have contained anywhere from 50 to 200 lb (23 to 91 kg) of "desensitized blasting gelatin" composed of nitrocellulose and nitroglycerine.[3] The guns themselves weighed over 200 tons, requiring the existence of a steam generator, air compressor, and other equipment to operate the guns.
After the guns were declared obsolete in 1904 due to significant technological advances in conventional artillery, the four batteries on which they were installed were decommissioned and the guns were scrapped for metal. Only two of the guns' original locations remain to this day; one abandoned battery is located at Fort Winfield Scott, in San Francisco, California, while the remains of another are located on the premises of a private resort on Hilton Head Island, South Carolina.
