President Trump has signed into law H.R. 5515, the John S. McCain National Defense Authorization Act for Fiscal Year 2019, authorizing the U.S. Department of Defense (DoD) to spend $9.6 billion for unmanned vehicle systems. The bill increases military spending for unmanned technologies by 28 percent over last year, according to an analysis by the Association for Unmanned Vehicle Systems International (AUVSI).

In its analysis, AUVSI notes that the total requested funding for unmanned technologies across all defense agencies comprises about 1.4 percent of the DoD’s FY2019 budget. Each military service—U.S. Navy, U.S. Air Force, and U.S. Army—had requested a funding increase for unmanned systems.

Among the services, the Navy received the largest funding increase for unmanned systems, with more than $1 billion authorized over last year’s defense budget. Unmanned aircraft systems (UAS) had the highest funding support at more than $7 billion, according to AUVSI’s review.
