How Much of Your Services Pipeline Is Coded as Manufacturing?
Sixty-one percent of the sustainment dollars coming off contract between February 2027 and August 2028 sit under an aircraft, missile, or shipbuilding NAICS. That one code sets the size standard, the set-aside pool, and whether your saved search ever sees the notice.
In April 2019, Army Contracting Command at Redstone Arsenal signed W58RGZ19C0027 with General Atomics Aeronautical Systems. The government's own description of the work opens with the words "performance based logistics support services."
The contracting officer filed the contract under NAICS 336411, Aircraft Manufacturing.
Seven years and $1,896,157,069 later, that award runs out on April 23, 2027, which puts it on our expiration board this morning as a manufacturing buy governed by a manufacturing size standard.
It has company.
What the board says
We refreshed the pipeline this morning: 1,212 live DoD prime contracts over $50M with periods of performance ending between Feb. 25, 2027 and Aug. 17, 2028, $407.78B obligated.
Pull out only the awards whose product or service code sits in a service class, groups B through Z. That is 560 contracts carrying $99.20B.
Of those dollars, $17.78B are filed under a NAICS code in sectors 31 to 33, manufacturing.
The interesting part is where they sit (chart below).

In PSC group J, maintenance and repair and rebuild of equipment, 61% of the expiring dollars carry a manufacturing NAICS, and in group H, quality control and test and inspection, it is 90% of $1.64B across seven contracts.
In construction and natural resources management, both of them multi-billion groups on this board, it is exactly zero.
The pattern follows the weapon system. Sustainment on a fielded platform gets the platform's industry code.
Why it lands there
FAR 19.102(b) leaves the contracting officer one slot and one test: "contracting officers shall assign one NAICS code and corresponding size standard to all solicitations, contracts, and task and delivery orders," determined by "classifying the product or service being acquired in the one industry that best describes the principal purpose."
Plenty of offices read the principal purpose of Apache logistics as the Apache.
SBA writes the same instinct into its own table. Footnote 7 at 13 CFR 121.201 sends contracts for the rebuilding or overhaul of aircraft ground support equipment to NAICS 336413, a manufacturing code.
And the size standard travels with the code, never with the work:
- 336411 Aircraft Manufacturing: 1,500 employees
- 336413 Other Aircraft Parts: 1,250 employees
- 336611 Ship Building and Repairing: 1,300 employees
- 541330 Engineering Services: $25.5M in receipts
- 541512 Computer Systems Design: $34.0M in receipts
A 900-person logistics firm doing $200M a year is a small business on the first three and comfortably large on the last two. Move one code and the rule-of-two pool changes membership.
The alert that never fires
Boeing's Apache Performance Based Logistics V notice posted to SAM on June 12, 2025 under solicitation number W58RGZ24C0028. Its own classification code is R706, logistics support.
Its primary NAICS is 336411. Award $101,615,048 to Mesa, out of W6QK ACC-RSA, no set-aside.
So the notice says "logistics support" in the field that describes the work and "Aircraft Manufacturing" in the field your saved search filters on. If your SAM alerts run on 541330, 541512, 541611 and 561210, that one never reached you.
The follow-on contract sits on our board at $506,134,738.95 obligated, still filed under 336411.
Ten calendar days
The code is contestable, and the window is short.
Under 13 CFR 121.1103, any interested party adversely affected by a NAICS designation may appeal it to SBA's Office of Hearings and Appeals, and the appeal "must be served and filed within 10 calendar days after the issuance of the solicitation or amendment affecting the NAICS code or size standard." OHA summarily dismisses a late one.
Here is the part worth writing on the capture plan. On receipt of the service copy, the contracting officer shall stay the date for the closing of receipt of offers.
A NAICS appeal stops the proposal clock while OHA decides. That is a real lever on a recompete where the assigned code puts you outside the pool, and it expires ten days after the solicitation drops, which is usually before anyone has finished reading the SOW.
Final Thoughts
None of this says a single one of those assignments is wrong. Principal purpose is a judgment call, and an office that has bought Apache sustainment for a decade has reasons for the code it uses.
What it does say is that the NAICS field is doing three jobs at once on this board: describing the industry, setting who counts as small, and routing the notice to whoever asked to be told. On $17.78B of expiring service work those three jobs point in different directions, and the reader who filters a pipeline by services NAICS codes is looking at a smaller market than the one that exists.
Thanks for reading.
