On November 7, 2025, Secretary of War Pete Hegseth used a speech at the National War College to unveil a Department of War (“DoW”) memorandum titled “Transforming the Defense Acquisition System into the Warfighting Acquisition System to Accelerate Fielding of Urgently Needed Capabilities to Our Warriors.”  This memorandum, referred to throughout as the “WAS Memo”—formally redesignates the Defense Acquisition System (“DAS”) as the Warfighting Acquisition System (“WAS”), places the acquisition enterprise on a “wartime footing,” and sets forth the governance, structural, and process reforms that will shape how DoW capabilities are acquired and fielded. 

This post is the second in a three-part series analyzing these reforms.  In our first post, we examined the WAS Memo’s new emphasis on commercial products and offerings as the preferred acquisition approach.  This post turns to the broader restructuring initiatives contained in the WAS Memo and its accompanying Acquisition Transformation Strategy.Continue Reading From DAS to WAS:  Secretary Hegseth’s Acquisition Overhaul and What It Means for Industry

On August 20, 2025, the Department of Defense (“DoD”) issued a sweeping memo that tears up and rebuilds the way the military decides what new weapons and systems it needs.  The Military Services appear to be wasting no time translating the memo into action.  Acquisition leaders at last week’s Association of the United States Army conference emphasized that “Transforming in Contact” will serve as the framework for redefining requirements and reprioritizing programs—demonstrating that reform is already underway.  For its part, the Air Force has begun reorganizing its A5/7 directorate to assume greater responsibility for requirements generation, while the Chief of Space Operations has publicly outlined the Space Force path to driving requirements and resourcing.  

This “requirements process” is the first step in acquisition—it defines the problem and tells the rest of the system what to buy, build, or develop.  Change the requirements process and you change the entire defense marketplace.  For decades, DoD has used a system called the Joint Capabilities Integration and Development System (“JCIDS”).  JCIDS was paperwork-heavy and checklist-driven:  the Military Services (Army, Navy, Air Force, Marine Corps, Space Force) would write lengthy justifications for new programs, and those proposals would wind their way through layers of approval at the Joint Staff in the Pentagon.  Critics said JCIDS was too slow and too rigid for modern threats, especially as China and other adversaries innovate quickly.

The August 20 memo blows up that model.  In its place, DoD is putting forward a problem-focused approach that aims to:

  • Define the biggest operational challenges first(not just collect Military Service wish lists)
  • Tie priorities to moneyso “important” projects actually get funded
  • Bring industry into the process earlierthrough experiments, not just proposals
  • Cut out layers of low value review

Below we unpack the memo and offer five practical takeaways for industry.Continue Reading JCIDS, Rewired:  What DoD’s New Requirements Memo Means

Two cornerstone authorities for federal contracting quietly expired on September 30, 2025, creating ripple effects that contractors—small and large—cannot afford to overlook.  The Small Business Innovation Research/Small Business Technology Transfer (“SBIR/STTR”) programs, commonly known as “America’s Seed Fund” for their role in fueling early-stage innovation, and the Defense Production Act…

On August 13, 2025, the White House issued Executive Order 14335, “Enabling Competition in the Commercial Space Industry” (“EO 14335” or the “EO”).  Framed as a push to “enhance American greatness by enabling a competitive launch marketplace and substantially increasing commercial space launch cadence and novel space activities by 2030,” EO 14335 directs federal agencies to reform regulatory barriers in four key areas:  (1) commercial launch and reentry, (2) spaceport infrastructure, (3) novel space activity authorization, and (4) leadership and accountability.  Sec. 2.  Each of these initiatives aims to streamline bureaucracy, reduce delays, and accelerate U.S. commercial space growth.  Below, we break down the EO’s provisions in each area and examine their significance for industry stakeholders.Continue Reading To Efficiency and Beyond?:  President Trump Issues Executive Order to Enable a Competitive Space Launch Market

The Defense Production Act (DPA) has long been viewed as the primary federal mechanism for managing and supporting defense production.  Since it was enacted in September 1950—just months after the Korean War began—the DPA has armed the President with wartime-style powers to prioritize contracts, allocate scarce materials, and finance surge defense production capacity.  These DPA industrial authorities are subject to periodic reauthorization, with the current sunset set for September 30, 2025.  While the reauthorization of the DPA remains pending, the Senate Armed Services Committee (SASC) has advanced a new NDAA provision that would convert the extant Industrial Base Fund (IBF) (10 U.S.C. section 4817) into a Pentagon-controlled toolkit that closely mirrors—but is not identical to—DPA’s Title III authorities.  The introduction of section 849A of the FY 2026 NDAA suggests that the SASC is no longer willing to entrust the re-armament of the Pentagon and revitalization of the Defense Industrial Base (DIB) solely to reauthorization of the DPA—a process that lives or dies in other committees’ jurisdictions. Continue Reading Forging a Modern Strategic Production Base:  Senate Proposes Stand-Alone Defense-Production Powers for the Pentagon

The Office of Management and Budget (OMB) has taken the next major step toward implementing the General Services Administration’s (“GSA”) Revolutionary FAR Overhaul (RFO), submitting to Congress 16 legislative proposals aimed at modernizing federal acquisition law and easing statutory burdens on both agencies and contractors on July 16, 2025. The…

As part of the One Big Beautiful Bill Act (“OBBBA”) signed into law by the President on July 4th, Congress made approximately $150 billion in appropriations to support defense and national security priorities.  As detailed further below, OBBBA touches on many different defense industries and sectors—including the maritime industry, missile systems, space and satellite technologies, nuclear technologies, and artificial intelligence and other advanced technologies.  Further, the OBBBA appropriates significant funding to support strategic investments in the defense industrial base and provides the Department of Defense (“DoD”) with an extended timeline (until 2029) to execute these investments.  Existing government contractors, and advanced technology providers interested in becoming contractors, should closely monitor the implementation of these OBBBA provisions, which will shape DoD opportunities for years to come.Continue Reading One Big Beautiful Bill Act makes $150B investment in Defense

The Trump Administration continues to focus on procurement reform aimed at increasing acquisition efficiency, including through the “Revolutionary FAR Overhaul” and reinforced preference for commercial products. Now, with the House Armed Services Committee (HASC) introducing a defense procurement reform bill, it is clear that HASC leadership is also targeting increased efficiency as a key goal of the Fiscal Year 2026 National Defense Authorization Act (FY26 NDAA). We cover the bill’s key proposals and their potential impact on defense contractors below.Continue Reading SPEEDing up Procurement?: House Armed Services Bill Seeks to Reform Defense Acquisition

On April 20th, a bipartisan, bicameral group of lawmakers, including Senator Mark Kelly (D-Ariz.) and Senator Todd Young (R-Ind.) in the Senate and Representative John Garamendi (D-Calif.) and Representative Trent Kelly (R-Miss.) in the House, reintroduced the Shipbuilding and Harbor Infrastructure for Prosperity and Security for America Act of 2025 (the “SHIPS Act” or the “Act”). The SHIPS Act’s sponsors describe the bill as a “comprehensive approach to revitalizing the U.S. Merchant Marine.” It aims to: (1) establish national oversight and consistent funding for U.S. maritime policy; (2) make U.S.-flagged vessels more commercially competitive through de-regulation; (3) rebuild the U.S. shipyard industrial base; and (4) expand and strengthen the maritime labor force. It also sets a goal for establishing a fleet of 250 U.S.-flagged vessels in international commerce.Continue Reading Reintroduced SHIPS Act Signals Continued Momentum for Domestic Maritime Investment

On April 9, 2025, President Trump issued an Executive Order (“EO”), “Modernizing Defense Acquisitions and Spurring Innovation In the Defense Industrial Base,” that may have significant implications for federal government contractors doing business with the Department of Defense (“DoD”), and particularly those with touchpoints to Major Defense Acquisition Programs (“MDAPs”).Continue Reading Trump Administration Issues Executive Order Aimed At Modernizing Defense Acquisitions And Spurring Innovation
