The Defense Systems Information Analysis Center (DSIAC) received a technical inquiry requesting information on the latest counter-unmanned aircraft system (C-UAS) solutions for the U.S. Army, Navy, Air Force, and Marine Corps. DSIAC reached out to C-UAS subject matter experts (SMEs) at the Joint Improvised-Threat Defeat Organization (JIDO) for relevant systems. The JIDO SMEs provided the Secret Internet Protocol Router Network (SIPRNet) URL address for the collected repository of UAS and C-UAS technologies. DSIAC also searched open sources and the Unmanned Airspace C-UAS database for systems deployed or funded by each of the U.S. Armed Services. The collected C-UAS solutions were compiled in a response report, and the SIPRNet URL can be requested.
The Defense Systems Information Analysis Center (DSIAC) searched open sources, the Defense Technical Information Center Research and Engineering Gateway, and the Unmanned Airspace C-UAS database to collect information on the latest technologies in use or development by the various U.S. Armed Forces for C-UAS defense. DSIAC contacted subject matter experts (SMEs) from the Joint Improvised-Threat Defeat Organization (JIDO) for data from their unclassified repository, the Propel database. There were 18 C-UAS technologies in this database, which can be accessed from the Secret Internet Protocol Router Network . Other C-UAS technologies were compiled and organized by each of the U.S. Armed Services branches.
2.0 U.S. Army Systems
2.1 Boeing/General Dynamics: Mobile Expeditionary High-Energy Laser (MEHEL) 2.0
The MEHEL 2.0 improves upon the original model by upgrading its C-UAS capabilities (e.g., it upgrades the original 2-kW laser to a 5-kW laser). The MEHEL is a laser testbed on a Stryker armored fighting vehicle chassis (shown in Figure 1) and serves as a platform for research and development. The MEHEL 2.0 engaged small, fixed-wing UAS’s and quad copters at the 2017 JIDO UAS Hard-Kill Challenge. The system, developed by the U.S. Army Space and Missile Defense Command, includes multiple U.S. Army Aviation and Missile Research, Development, and Engineering Center C-UAS components. The MEHEL 2.0 is the first use of an Army laser on a combat vehicle; this is a result of recognizing high-energy lasers (HEL) as potential low-cost complements to other kinetic kill C-UAS options [2, 3].
