Evidence of open-source adoption
Open-source movement in the military — The military has explored open-source software for potential operational benefits. Open-source software allows modification by multiple contributors, potentially offering cost-effective development and rapid customization capabilities. Military interest stems from the possibility of increased development speed and operational flexibility. However, security considerations arise due to the open nature of code modification and access. The Military Open Source Software Working Group, established in 2009 with over 120 military members, was organized to facilitate collaboration between software developers and contractors from military organizations. The group aimed to explore opportunities for code reuse and collaborative development in military applications.
