Notes If there's one thing you want your multi-million dollar electromagnetic railgun to be, it's reliable, and the US Navy announced today that it's reached a key milestone towards that goal. It's now successfully fired its prototype gun 1,000 times, which translates to as many as 15 shots per week. In recent years, those tests have generally been conducted at a 1.5 megajoule launch energy, which the Navy puts into perspective by noting that "a one-ton vehicle moving at 100 mph has approximately one megajoule of kinetic energy." Eventually, the Navy hopes to install even more advanced and far more powerful railgun weapons systems on ships, although the project's future remains a bit up in the air given some recent funding battles in the US Senate.

Notes"Hwacha or Hwach'a .[1] was an anti-personnel gunpowder weapon developed and used in Korea, inspired by Chinese fire arrows and the cylindrical and box shaped launch platforms that fired them. Hwacha were first developed in the 1400s by Korean scientists. It is a two-wheeled cart carrying a launch pad or board, filled with holes into which the ammunition is inserted. These small rockets are attached to "Gungdo bow-arrows", which shoot about 100 to 200 iron spikes at one time upon detonation.[citation needed] During combat, the projectiles are attached to the arrows, ignited and fired. This ammunition was transported on wheelbarrows [1]. Many East Asian historians believe this technological breakthrough alongside the turtle ship in the mid-16th century had a distinctive effect during the Japanese invasions of Korea (1592-1598) [2]."FeedUnfurl
