Machine guns and torpedo tubes, the more things change…
Here we see a warrant officer in dress whites aboard USS Walke (Destroyer # 34) leaning jauntily on a stanchion-mounted machine gun, circa 1914. This weapon is a .30 caliber U.S. Model 1909 Machine Rifle (Benét-Mercié), a modification of the French Hotchkiss Portative. The gun appears to be on an AAA mount, which is novel for the time.
Walke, an early Paulding-class destroyer, carried as her main battery a half-dozen 18-inch deck-mounted torpedo tubes, intended to poke holes in enemy ships. Her gun armament consisted of five 3-inch guns and a few European-designed machine guns, as shown. Commissioned in 1911, she remained in the fleet until 1934.
Fast forward 105 years…and you still have destroyers with a few .30-caliber European-designed machine guns as well as a half-dozen deck-mounted torpedo tubes, intended to poke holes in enemy ships, albeit of the submarine nature.
