Introduction

On February 27, 2026, the Defense Industrial Base Consortium (DIBC) issued a new Request for Project Proposals (RPP) focused on Strategic and Critical Materials.  Phase 1 submissions are due March 20, 2026, at 5:00 p.m. (Eastern).  

This solicitation represents the second DIBC RPP targeting critical minerals since the issuance of Executive Order (EO) 14241, “Immediate Measures to Increase American Mineral Production.”  The EO directed federal agencies to expand domestic access to critical minerals and reduce reliance on foreign supply chains. Continue Reading Defense Industrial Base Consortium Issues New Critical Minerals Request for Project Proposals

On February 17, 2026, the Federal Acquisition Regulatory Council released a Notice of Proposed Rulemaking, proposing amendments to the FAR to implement Section 5949 of the FY23 National Defense Authorization Act (“NDAA”).  Section 5949 prohibits executive agencies from obtaining semiconductor parts, products, or services traceable to certain named Chinese companies – currently, Semiconductor Manufacturing International Corporation (“SMIC”), ChangXin Memory Technologies (“CXMT”), and Yangtze Memory Technologies Corp (“YMTC”) – subject to limited exceptions.  In accordance with the statute, the proposed amendments to the FAR would become effective on December 23, 2027.  The proposed rule is not yet final and is open for public comment until April 20, 2026. Continue Reading FAR Council Issues Notice of Proposed Rulemaking to Implement Prohibition on Acquisition of Certain Semiconductors

On January 23, 2026, the Office of Management and Budget (OMB) issued Memorandum M-26-05 “Adopting a Risk-based Approach to Software and Hardware Security,” which rescinds a previous Biden Administration’s requirement for all federal agencies to obtain a self-attestation from software producers in the “Common Form” developed by the Cybersecurity and Infrastructure Security Agency (CISA) before using certain third-party software.  As its rationale, OMB noted that the prior memoranda diverted agencies from developing tailored assurance requirements and failed to account for threats posed by insecure hardware.  Memorandum M-26-05 signals that the federal government is moving away from a “one-size fits-all” approach to software security and will instead allow each agency to develop tailored requirements.  In creating their own assurance requirements, agencies may still require a self-attestation and/or Software Bill of Materials (SBOM) from the software vendor if the agency determines that such assurances are necessary based on the risks involved and the agency’s needs.Continue Reading OMB Rescinds the “Common Form” Secure Software Attestation Requirement

As the federal government focuses on securing reliable supplies of critical minerals, stockpiling has emerged as a key policy tool, alongside direct investments in private enterprises and expanded funding programs for industry.  The National Defense Stockpile (“NDS”) currently serves as the federal strategic reserve of materials needed for national defense, including critical minerals, and the growing policy attention has prompted new proposals and initiatives for upgraded federal stockpiling capabilities.  This blog post reviews the NDS and its activities last year and offers an outlook for critical minerals stockpiling in the year ahead.  Continue Reading Federal Push for Critical Minerals Stockpiling: 2025 in Review and Outlook for 2026  

The past month has marked a series of announcements from the Department of War (the “Department”) emphasizing rapid deployment of artificial intelligence (“AI”) industry partnerships.  These announcements signal opportunities for not only the defense industrial base, but also nontraditional defense contractors focused on technology and data.

On January 9, 2026, the Department released two key memoranda: (1) Artificial Intelligence Strategy for the Department of War, setting out measurable pace-setting projects, barrier removal authorities, and mandated data access; and (2) Transforming the Defense Innovation Ecosystem to Accelerate Warfighting Advantage, which aims to unify the defense innovation ecosystem under the Under Secretary of War for Research & Engineering as Chief Technology Officer (“CTO”).  

Shortly after, on January 12, Secretary Hegseth delivered a speech, presenting an overhaul of the Department’s innovation and acquisition ecosystems.

The January 9 memoranda and Secretary Hegseth’s speech signal the Department’s intent to formalize a single, CTO-led innovation operating system designed to produce three outputs: next-generation technology, scalable products, and new ways of fighting—and to do it at “wartime speed,” with AI as the first major proving ground.Continue Reading Pentagon Releases Artificial Intelligence Strategy

Among the most challenging areas of regulatory compliance for federal contractors are cost accounting and cost and pricing data disclosure requirements.  Indeed, many companies place guardrails on the nature and scale of their business relationships with the U.S. government precisely to avoid the application of these requirements.  In a move that seems consistent with the federal government’s push towards expanding the defense industrial base and working with more commercial companies, Congress recently released the final negotiated language of the FY 2026 National Defense Authorization Act (“NDAA”).  The draft text, currently awaiting a full Senate vote, contains impactful changes to reduce the applicability of federal Cost Accounting Standards (“CAS”) and the Truthful Cost or Pricing Data Statute (formerly the Truth in Negotiations Act, commonly referred to as “TINA”). Continue Reading FY26 NDAA Aims to Raise the Dollar Thresholds for the Applicability of CAS and TINA

Recently, in Cosette Pharmaceuticals, Inc. v. United States, the Court of Federal Claims sustained a bid protest, finding that the agency misapplied the Trade Agreements Act (“TAA”) during proposal evaluation.  That decision is a helpful reminder that the Court can be a hospitable forum for challenging an agency’s application of domestic sourcing regulations.Continue Reading COFC Reaffirms Domestic Sourcing Regulations as a Viable Basis for Bid Protests
