The Ukrainian company is not being named because of security reasons. The agreement was signed on Oct. 1 during the DFNC2 International Defense Industries Forum in Kyiv, where nearly 300 companies from over 30 countries attended. The Switchblade 600 is a loitering munition used to strike targets by crashing into them. They have a flight range of 40 kilometers or more, and can stay in the air for over 40 minutes. Brett Hush, a senior vice president at AeroVironments who signed the agreement in Kyiv, praised the Switchblade's performance and added, "with the support and feedback from Ukraine, it'll be even better." The Switchblade 600 has been included as part of U.S. assistance packages to Ukraine since 2022. The agreement was one of several signed at the forum to increase joint production between Ukrainian and foreign companies as Ukraine builds its defense capabilities two and a half years into Russia's full-scale invasion.The Prague-based Czechoslovak Group signed an agreement for production of several types of heavy artillery ammunition, including 155 shells.
