Stephanie Barna draws on over three decades of U.S. military and government service to provide advisory and advocacy support and counseling to clients facing policy and political challenges in the aerospace and defense sectors.

Prior to joining the firm, Stephanie was a senior leader on Capitol Hill and in the U.S. Department of Defense (DoD). Most recently, she was General Counsel of the Senate Armed Services Committee, where she was responsible for the annual $740 billion National Defense Authorization Act (NDAA). Additionally, she managed the Senate confirmation of three- and four-star military officers and civilians nominated by the President for appointment to senior political positions in DoD and the Department of Energy’s national security nuclear enterprise, and was the Committee’s lead for investigations.

Previously, as a senior executive in the Office of the Army General Counsel, Stephanie served as a legal advisor to three Army Secretaries. In 2014, Secretary of Defense Chuck Hagel appointed her to be the Principal Deputy Assistant Secretary of Defense for Manpower and Reserve Affairs. In that role, she was a principal advisor to the Secretary of Defense on all matters relating to civilian and military personnel, reserve integration, military community and family policy, and Total Force manpower and resources. Stephanie was later appointed by Secretary of Defense Jim Mattis to perform the duties of the Under Secretary of Defense for Personnel and Readiness, responsible for programs and funding of more than $35 billion.

Stephanie was also previously the Deputy General Counsel for Operations and Personnel in the Office of the Army General Counsel. She led a team of senior lawyers in resolving the full spectrum of issues arising from Army wartime operations and the life cycle of Army military and civilian personnel. Stephanie was also a personal advisor to the Army Secretary on his institutional reorganization and business transformation initiatives and acted for the Secretary in investigating irregularities in fielding of the Multiple Launch Rocket System and classified contracts. She also played a key role in a number of high-profile personnel investigations, including the WikiLeaks breach. Prior to her appointment as Deputy, she was Associate Deputy General Counsel (Operations and Personnel) and Acting Deputy General Counsel.

Stephanie is a retired Colonel in the U.S. Army and served in the U.S. Army Judge Advocate General’s Corps as an Assistant to the General Counsel, Office of the Army General Counsel; Deputy Staff Judge Advocate, U.S. Army Special Forces Command (Airborne); Special Assistant to the Assistant Secretary of the Army (Manpower & Reserve Affairs); and General Law Attorney, Administrative Law Division.

Stephanie was selected by the National Academy of Public Administration for inclusion in its 2022 Class of Academy Fellows, in recognition of her years of public administration service and expertise.

Over one year ago, on May 2, 2025, the FAR Council took the first concrete step in the administration’s “Revolutionary FAR Overhaul” (“RFO”) initiative by issuing the initial round of rolling model deviation guidance—a deliberate move to translate reform of the Federal Acquisition Regulation (“FAR”) from an abstract policy goal into acquisition text.  That moment marked the beginning of a new implementation reality: rather than waiting for a single, comprehensive rulemaking, the government began operationalizing the overhaul in increments, part by part, through deviations.  Now, a year later, the question for contractors is no longer whether the overhaul is “coming,” but how it is being implemented across agencies and systems.  This is therefore a good time to take stock of where implementation stands, where friction is emerging, and what sophisticated contractors can do to stay ahead of the curve.  For additional information, our prior coverage of the RFO roll-out can be found here and here.

On April 29, 2026, Secretary of War Pete Hegseth told the House Armed Services Committee that the Pentagon will “shortly announce a sub-unified command of autonomous warfare.”  The announcement came as the Department of War (DoW) unveiled its fiscal year (FY) 2027 budget request, which proposes approximately $54 billion for the Defense Autonomous Warfare Group (DAWG)—a dramatic increase from the roughly $226 million the DAWG received previously.  When all DoW drone and counter-drone related budget lines in the FY 2027 budget request are aggregated, the total approaches $74 billion—an amount Pentagon officials have described as the largest investment in such technologies in U.S. history.  

Beyond the headline numbers, Secretary Hegseth’s reference to a “sub-unified command” is institutionally significant.  It raises fundamental questions about how the DoW intends to organize autonomous warfare inside the joint force and warrants a closer look at what a sub-unified command actually is.

On April 20, 2026, one week after President Trump signed the Small Business Innovation and Economic Security Act (Public Law 119-83) into law, the Department of War (“DoW”) issued a press release announcing that it was “immediately advancing” a “redesigned and more focused initiative to accelerate the delivery of advanced capabilities to the warfighter.”  As we covered last month, the Small Business Innovation and Economic Security Act reauthorizes the Small Business Innovation Research and Small Business Technology Transfer (“SBIR/STTR”) programs through September 30, 2031, ending a nearly six-month lapse that froze new SBIR/STTR solicitations and awards across federal agencies.

The DoW’s announcement signals that the Department intends to be the first mover in implementing the reauthorized SBIR/STTR programs.  The announcement also introduces a new initiative, the Accelerated Research for Transition (“ART”) Program, that warrants close attention from the defense small business community.

On March 13, 2026, President Trump issued an Executive Order (EO) titled “Adjusting Certain Delegations Under the Defense Production Act.”  As we have covered in prior blog posts, the Defense Production Act (DPA) has traditionally been considered the primary federal means to manage and support defense production.

On March 13, 2026, the Department of Energy issued a Notice of Funding Opportunity (NOFO) for projects supporting the development of domestic processing, manufacturing, and recycling capabilities for battery materials.  With $500 million in total available funding, the NOFO solicits proposals in three topic areas: (1) domestic critical minerals processing from raw feedstocks, (2) domestic critical minerals recycling, and (3) domestic battery materials and component manufacturing.  Letters of intent are due March 27, 2026, and full applications are due April 24, 2026.

On March 3, 2026, the Senate took a major step toward reauthorizing the Small Business Innovation Research/Small Business Technology Transfer (“SBIR/STTR”) programs, by passing the Small Business Innovation and Economic Security Act (S. 3971).  Known collectively as “America’s Seed Fund,” the SBIR and STTR programs provide small businesses with early-stage

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.

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.

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”).

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.
