The Deputy Secretary of War's 14 September 2026 memorandum, Fostering One Strong Industrial Base, directs the Department from Cost Accounting Standards to GAAP, sets a 60-day clock for proposals to the Cost Accounting Standards Board, and — effective on signature — bars any solicitation that would newly bring a business unit under full CAS coverage unless the Under Secretary for Acquisition and Sustainment approves the acquisition strategy in writing.

FAR Case 2026-011 would remove contractor team arrangements from the FAR entirely and, implementing section 812(a)(6) of the FY2026 NDAA, excuse the Department of War from paying for a small business to undergo qualification testing where fewer than two manufacturers could compete. Civilian agencies keep that obligation.

Class Deviation 2026-O0046, Revision 1, posted 9 September 2026, revises DFARS Part 245 so that nontraditional defense contractors are exempt from DFARS 252.245-7003, Contractor Property Management System Administration, unless a contracting activity head waives the exemption.

DFARS Parts 244 and 231 were revised on 29 July and 4 August 2026 to implement FY2026 NDAA section 1826. Cost principles and purchasing system approval no longer apply to nontraditional defense contractors on Department of War contracts.

Class Deviation 2026-O0006, Revision 1, issued 30 July 2026, implements FY2026 NDAA section 1806 and doubles both the full-versus-modified CAS coverage line and the disclosure statement trigger. The CAS Board has since made the change government-wide effective 1 October 2026, but the FAR Part 30 overhaul text still carries the old figures.

A Cost Accounting Standards Board final rule published 1 September 2026 raises the basic CAS applicability threshold from $2.5 million to $35 million, doubles the full-coverage and Disclosure Statement threshold to $100 million, and sets how CAS exemptions apply to indefinite delivery contracts.

A 24 July 2026 Department of War class deviation implements FY2026 NDAA sections 812(c), 1826, and 811(a)(5), converts the TINA Lite pilot into a permanent program, and changes should-cost review requirements.
