The Tomahawk (UK /'t?m?h??k/ or US /'t??m?h??k/) is a long-range, all-weather, subsonic cruise missile. The missile was named after the Native American axe. Introduced by McDonnell Douglas in the 1970s, it was initially designed as a medium to long-range, low-altitude missile that could be launched from a surface platform. It has been improved several times, and due to corporate divestitures and acquisitions, is now made by Raytheon. Some Tomahawks were also manufactured by General Dynamics (now Boeing Defense, Space & Security).
