W19 Artillery Shell: Small but Powerful

The W19 was a nuclear artillery shell that the United States developed for use from an 11-inch howitzer in the 1950s. With a yield of up to 15 kilotons, the W19 ranked among the smallest nuclear weapons ever developed by the US, yet it possessed sufficient power to inflict significant damage. However, the W19 was never produced in large quantities and was eventually phased out in the 1960s.
