Defense acquisition priorities are crystallizing around next-generation platforms, with Space Force terminating a troubled GPS modernization program while advancing cislunar capabilities and the Navy narrowing its sixth-generation fighter competition. Cybersecurity threats are intensifying across multiple attack surfaces—from actively exploited infrastructure vulnerabilities requiring emergency patches to sophisticated supply chain compromises targeting widely-used development tools. Meanwhile, regulatory frameworks are expanding to address emerging AI risks, as the FTC broadens enforcement into deepfakes and voice cloning scams while Russia escalates mobile security threats against encrypted communications.
