The Government Accountability Office has denied a challenge from The NORDAM Group, LLC to the Navy's decision to award a single indefinite-delivery, indefinite-quantity contract for repair and modification of SUU-79 pylons to Vertex Modernization and Sustainment LLC, rejecting the Tulsa-based aerospace firm's argument that a multiple-award structure would have saved taxpayers roughly $19.2 million. The full decision is available at GAO's B-424390 docket.
Background
The Naval Supply Systems Command (NAVSUP) issued RFP No. N00383-25-R-001D seeking a contractor to repair and modify SUU-79 pylons, hardware used to mount external stores on naval aircraft. The solicitation expressly reserved the government's right to make a single IDIQ award rather than splitting the work among multiple vendors. NORDAM, an established Tulsa aerospace repair and overhaul company, competed for the work but lost out to Vertex Modernization and Sustainment LLC, an Indianapolis-based contractor. After the award, NORDAM filed a protest with GAO challenging both the single-award decision and the way the Navy conducted discussions during the competition.
NORDAM's central argument was economic: it contended that awarding the work to a single contractor, rather than distributing it across two or more IDIQ holders who would then compete for individual task orders, would cost the government approximately $19.2 million more than a multiple-award approach would have. NORDAM also argued the Navy mishandled discussions related to small business participation requirements and improperly evaluated Vertex's small-business subcontracting credentials.
Key Details
GAO rejected the $19.2 million single-award argument on procedural grounds before ever reaching its merits. Under 4 C.F.R. § 21.2(a)(1), a protester challenging an alleged solicitation impropriety must raise that objection before the deadline for receipt of proposals, not after an award has already been made. Because the RFP had explicitly reserved the Navy's right to make a single award, GAO found that any objection to that structure needed to have been raised during the solicitation period. NORDAM's post-award protest on this ground was therefore untimely, and GAO dismissed it without evaluating whether the $19.2 million figure was accurate or whether a multi-award structure would in fact have been cheaper.
On the discussions issue, NORDAM argued the Navy's discussion letters left it confused about how to calculate its proposed small business participation percentage, which the solicitation set at 15% of total contract value. GAO reviewed the actual discussion correspondence and found the Navy's letters were clear and unambiguous about what NORDAM needed to address, stating the requirement was calculated as a percentage of the total contract value. The decision states that NORDAM's own miscalculation of its small business participation figure, not any ambiguity or error in the Navy's discussions, produced the deficiency in its final proposal revision. Compounding the problem, NORDAM's corrective submission attempting to fix the miscalculation arrived roughly two months after the deadline set for final proposal revisions. GAO found the Navy properly rejected that late submission under FAR 52.215-1, which governs the exchange of information during negotiated procurements and sets firm deadlines for proposal revisions.
NORDAM's remaining ground challenged the Navy's evaluation of Vertex's small-business status and subcontracting relationships, arguing the agency had not adequately verified Vertex's claims. GAO found the Navy's evaluators had reasonably confirmed Vertex's small-business subcontractor relationships, its prior experience performing Navy work, and its documented history of meeting small business participation goals. GAO concluded the verification the Navy performed was adequate and that NORDAM had not shown the agency's evaluation of Vertex was unreasonable.
With all three grounds addressed, GAO denied the protest in its entirety on July 7, 2026, allowing the Navy's award to Vertex Modernization and Sustainment LLC to stand.
What It Means for Contractors
The decision underscores a timing trap that catches protesters regularly: once a solicitation reserves the government's right to make a single award, any objection to that structure has to be raised before proposals are due. Waiting until after losing the competition to argue that a different contract structure would have been better, even with a specific cost estimate attached, will be dismissed as untimely regardless of the argument's underlying merit. Contractors who believe a solicitation's award structure disadvantages them, or the government, need to file that challenge during the solicitation period, not after an unfavorable award decision.
The case also illustrates the risk of miscalculating proposal figures during discussions, then blaming the agency for a lack of clarity. GAO's review of the actual correspondence found the Navy's discussion letters were unambiguous, which meant the burden of the resulting deficiency fell entirely on NORDAM. Contractors engaged in discussions should treat agency questions about specific evaluation figures, such as small business participation percentages, as precise, and should verify their own calculations independently rather than assuming any confusion originated with the agency's language.
Finally, the decision confirms that late corrective submissions carry real consequences even when a contractor is trying to fix a legitimate error. A revision arriving two months past the deadline for final proposal revisions gave the Navy clear grounds under FAR 52.215-1 to reject it outright, regardless of whether the correction would have improved NORDAM's competitive standing. Contractors managing multiple ongoing proposal actions should treat final proposal revision deadlines as firm cutoffs, since GAO has shown little tolerance for late submissions even when errors are self-identified and corrected in good faith.
For firms competing on future NAVSUP or other Navy repair and sustainment IDIQs, the decision also offers a preview of how GAO will treat challenges to a competitor's small-business subcontracting credentials. Because the Navy's evaluation weighed Vertex's documented relationships with subcontractors and its track record on prior small business commitments, rather than relying solely on the offeror's own representations, GAO found the agency's due diligence sufficient. Protesters hoping to overturn an award by attacking an awardee's small-business status should be prepared to identify specific errors or omissions in that kind of independent verification, rather than simply asserting that the awardee's credentials look questionable on their face.
GAO's bid protest decisions are not subject to direct appeal, though disappointed offerors retain the option of filing a follow-on action at the U.S. Court of Federal Claims. With the GAO protest denied, the Navy's IDIQ award to Vertex Modernization and Sustainment LLC for SUU-79 pylon repair and modification work remains in place.
