Bottom Line Up Front (BLUF): Secretary of War Hegseth ordered the Department of War (DoW) to overhaul the entire acquisition enterprise, redesignating the Defense Acquisition System (DAS) as the “Warfighting Acquisition System” (WAS). This marks the most sweeping decentralization of authority since the Packard reforms. Speed-to-field, modularity, and private-capital engagement will replace compliance and documentation as the organizing principles of defense procurement. Power is shifting from Service Secretariats to newly created Portfolio Acquisition Executives (PAEs), who will have expanded authority to waive requirements, approve reprogramming, and engage industry directly.
