The Defense Department has issued a revised class deviation to DFARS Part 207 that repeals a long-standing statutory term limit on leasing vessels, aircraft, and vehicles, and eases the approval process contracting officers must follow when a program wants to buy a larger quantity of an end item than originally planned.
The deviation, tracked as DARS 2026-O0020 Revision 1, was signed and became effective on September 2, 2026, according to the memo issued by the Office of the Under Secretary of Defense for Acquisition and Sustainment. Government contracts firm PilieroMazza flagged the deviation in its September 10, 2026 weekly update for government contractors, noting it implements sections 811 and 812 of the fiscal year 2026 National Defense Authorization Act.
What Section 811 Changes for Lease Contracts
Section 811 of the FY2026 NDAA repeals the term limitation that previously governed how long the Defense Department could lease vessels, aircraft, or vehicles rather than buy them outright. Term-limited leasing rules have historically existed to prevent agencies from using leases as a way to sidestep the budgetary scoring and procurement processes tied to outright purchases — a long-term lease can function economically much like ownership while avoiding the full upfront cost recognition of a purchase. Repealing that term limit gives DoD program offices substantially more flexibility to structure longer leases for vessels, aircraft, and vehicles without running into a hard statutory ceiling on lease duration.
The deviation memo quotes the underlying statutory language directly, describing "Section 811 of the NDAA for FY 2026, which repeals the term limitation for lease of vessels, aircraft, or vehicles." That direct implementation into DFARS Part 207 means contracting officers can now apply the change immediately, even though the formal DFARS rulemaking process to permanently codify the language will take months or years to complete through notice-and-comment procedures.
Section 812 Loosens Quantity-Increase Approvals
The second half of the deviation addresses Section 812 of the same NDAA, which changes who has authority to approve a program's acquisition of an end item in a higher quantity than originally planned, and removes some existing approval requirements altogether for additional-quantity buys. In practice, this reduces a layer of internal review that previously could slow down decisions to increase order quantities on an already-established program — a change that should let program offices move faster when scaling up production of items already under contract.
The revised deviation also folds in an earlier class deviation, 2026-O0003, relocating bundling-notification requirements from DFARS Part 205 to a new home in DFARS 207.107. That consolidation moves procurement-bundling disclosure rules — which govern how agencies must notify small businesses when contract requirements are combined in ways that could exclude smaller competitors — into the same part of the DFARS that now houses the revised leasing and quantity-approval language.
Class Deviations Move Faster Than Formal Rulemaking
DoD uses class deviations specifically because they let the department implement statutory changes immediately upon a NDAA's enactment, rather than waiting for the full DFARS rulemaking process, which typically involves a proposed rule, a public comment period, and a final rule that can take a year or more from start to finish. The deviation route means contracting officers are bound to follow the new lease and quantity-approval rules right away, even though the formal regulatory text implementing sections 811 and 812 hasn't yet worked its way through the standard DFARS case process. Contractors and agencies should expect the underlying DFARS text to eventually catch up with a formal rule, but the practical effect on today's contracting actions is already in force.
Why the Bundling Relocation Matters Too
The decision to fold Class Deviation 2026-O0003 into this revised memo, which replaces the bundling-notification requirement previously spelled out in DFARS Part 205 with a reference pointing to DFARS 207.107, is more than a bookkeeping change. Bundling rules require agencies to notify affected small businesses and industry when the government combines what would otherwise be separate, smaller-dollar requirements into a single larger contract — a practice that can squeeze small businesses out of competitions they would otherwise be positioned to win. By relocating those notification requirements into the same DFARS part that now governs leasing and quantity-increase determinations, DoD is consolidating a related set of acquisition-strategy decisions — how much to buy, how long to lease, and whether to bundle requirements — into a single regulatory location that contracting officers and small-business specialists will need to reference together going forward.
For law firms and compliance teams tracking DFARS changes, that consolidation means anyone monitoring bundling notification obligations under the old Part 205 citation needs to update internal references and checklists to point to the new Part 207 location, or risk citing outdated regulatory text in proposals, protests, or compliance filings.
What It Means for Contractors
Companies that lease vessels, aircraft, or vehicles to the Defense Department — a niche but persistent segment of federal contracting that includes charter and support-vessel operators, aircraft lessors, and specialized vehicle providers — should revisit lease proposals and existing negotiating positions in light of the repealed term limit. Longer-duration leases are now a viable structuring option without running into the prior statutory ceiling, which could open new bidding strategies for companies competing on multi-year lease arrangements rather than outright sales.
Contractors on programs where the government might want to increase order quantities should also take note: the eased approval process under Section 812 means program offices may be able to move more quickly to exercise additional-quantity options or negotiate expanded buys, without the delay previously imposed by the removed approval layer. Contractors positioned to scale production quickly may find shorter turnaround times between a government decision to buy more and an actual modification or task order reflecting that decision.
