Joint Interagency Task Force Supports Army Counter-UAS Assessment in Lithuania
JIATF 401 enabled standardized testing of emerging counter-unmanned aerial system capabilities during Project Flytrap 5.0, a U.S.-allied training exercise in Lithuania. The assessment establishes uniform evaluation criteria that participating forces will apply to new systems before field deployment.
Substrate placeholder — needs reviewVILNIUS, Lithuania — The Joint Interagency Task Force 401 supported the Army's assessment of emerging counter-unmanned aerial system capabilities during Project Flytrap 5.0, a training exercise that brought together U.S. and allied forces, according to a U.S. Department of Defense release dated May 12, 2026.
The exercise involved U.S. Army units and multiple allied contingents conducting standardized tests on counter-UAS platforms. JIATF 401 provided the assessment framework used to evaluate system performance against representative threats. Project Flytrap 5.0 marks the fifth iteration of the exercise series focused on counter-drone technologies.
The new standardized assessment replaces service-specific evaluation methods with a single joint protocol. Forces now apply uniform metrics for detection range, tracking accuracy, engagement success rates and electronic warfare compatibility. The protocol took effect immediately upon completion of the Lithuania phase of Project Flytrap 5.0.
Downstream effects include faster procurement decisions for counter-UAS systems across participating allies because test data can be shared without requalification. U.S. European Command units gain a common reference baseline for integration into existing air defense networks.
NATO partners must now align their own counter-UAS acquisition timelines to the JIATF 401 framework when purchasing systems tested under the new standard. Congress receives the assessment results as part of the annual counter-UAS roadmap required under current defense authorization language.
This marks the latest in a series of JIATF 401-enabled exercises that began after the task force stood up in 2023 to coordinate counter-UAS efforts across military services, the Department of Homeland Security and allied partners. The original Project Flytrap series launched in 2022 to address the rapid proliferation of small unmanned aircraft systems observed in Ukraine.
