How the U.S. Army Is Using Old Artillery to Fire Hypervelocity 'Bullets'

Due to its ability to reach speeds of up to 5,600 miles per hour, the hypervelocity projectile is engineered as a kinetic energy warhead, meaning no explosives are necessary. The hyper velocity projectile can travel at speeds up to 2,000 meters per second, a speed which is about three times that of most existing weapons. The rate of fire is 10-rounds per minute, developers explained at last years' briefing.

The First Aircraft Carrier Air Strike: Camels vs. Zeppelins in the Tondern Raid

Nearly a century ago during World War I, the Royal Navy launched the first air strike from an aircraft carrier ever, targeting a zeppelin base in Tondern. After dropping a cumulative bomb load that barely exceeded the weight of a single five-hundred-pound bomb carried by a typical World War II fighter, the naval strike planes all proceeded to crash in the sea or were forced to land on neutral territory.

This attack actually constituted an enormous success—and remains a landmark in the history of naval aviation.
