AQAP 2110 vs AS 9100: Which Standard to Choose for Defense and Aerospace Manufacturers (2026)

AQAP 2110 vs AS 9100 is a question we hear every week from Ukrainian manufacturers of UAVs, rocket systems, and navigation equipment. The short answer: AQAP 2110 is a NATO standard for defense suppliers — it's narrower in scope (defense contracts with NATO-compatible customers only). AS 9100 is an IAQG standard for the aerospace industry — it's broader: it covers civil aviation, medium and heavy UAVs, rocket systems, satcom equipment, and includes defense aerospace within its scope.

For a small FPV manufacturer building drones for an assault unit and not going beyond ground-systems — AQAP 2110 alone is enough. For a civil aerospace components manufacturer supplying brackets to Airbus tier-1 — AS 9100 alone is enough. But a MALE/HALE-class UAV manufacturer who chases NATO contracts and also needs airworthiness certification almost always needs both standards, integrated via the IAQG 9137 guidance.

This matters for Ukraine's defense industry, because picking the wrong standard costs 4-8 months of quality system rework and tens of thousands of euros. Let's go through how to avoid the mistake.

Before comparing, you have to nail down what each standard actually is — these are different documents from different organizations, with different legal weight and different scope.

AQAP 2110 Edition D Version 1 — a publication of the NATO Standardization Office (NSO, Brussels), in force since 2016. AQAP stands for Allied Quality Assurance Publication. It's a defense overlay that incorporates all ISO 9001:2015 requirements and adds 8 blocks of defense-specific requirements for NATO contracts: configuration management, traceability, evidence base for GQAR, customer audits. Published under STANAG 4107 — the agreement on mutual recognition of government quality assurance among Alliance countries. A contractual requirement for serious defense tenders. More detail in our complete AQAP 2110 guide.

AS 9100 Rev D — an IAQG (International Aerospace Quality Group) standard, released in 2016. Built on ISO 9001:2015 and adds aerospace-specific requirements: product safety, FOD (Foreign Object Debris) prevention, counterfeit parts prevention, configuration management at the flight-component level, specific requirements for critical characteristics and risks. Published by SAE International as ANSI/SAE AS9100D and has a European equivalent EN 9100:2018 (the same document, different cover). Per SAE, over 19,000 organizations worldwide are certified to AS/EN 9100 — the most widespread quality standard in aerospace.

The key difference in nature: AQAP 2110 is issued by NATO and is a contractual defense-sector requirement. AS 9100 is issued by IAQG (a consortium of Boeing, Airbus, Lockheed, Embraer, Bombardier, and others) and is de facto mandatory for working in the aerospace supply chain — both civil and military. AQAP is the entry ticket to a NATO defense tender. AS 9100 is the entry ticket to the Boeing/Airbus/Lockheed supply chain and the whole aerospace vertical.

Let's look at seven blocks where the two standards diverge in substance. Many quality managers think AS 9100 "includes" AQAP 2110 because of its broader scope — that's a myth. The NATO defense overlay has its own requirements that AS 9100 doesn't replicate, and vice versa — AS 9100 aerospace requirements are absent from AQAP 2110 entirely.

1. Scope. AQAP 2110 is defense supply only: NSPA contracts, national MoDs of NATO countries, prime defense contractors (Lockheed, BAE, Rheinmetall, Thales, Leonardo). AS 9100 is aerospace + defense: civil aviation, UAVs (especially medium and heavy class), satcom satellites, rocket systems, aviation MRO, plus defense aerospace. AS 9100 is formally broader, but the defense piece inside it doesn't cover AQAP requirements.

2. Publisher and governance. AQAP 2110 is issued by the NATO Standardization Office, with updates flowing through the NATO Conference of National Armaments Directors. AS 9100 is issued by IAQG — a private consortium of aerospace OEMs, with updates flowing through Boeing/Airbus/Lockheed consensus. This affects the pace of changes and how requirements are interpreted: AQAP updates slowly (Edition D Version 1 has been current since 2016), AS 9100 moves faster (the next revision is expected within 1-2 years).

3. Technical product requirements. AS 9100 has blocks that simply don't exist in AQAP 2110: product safety requirements (section 8.1.3), management of critical items / key characteristics, specific design and verification requirements for flight hardware, risks tied to human life in flight. AQAP 2110 doesn't have these blocks because the standard isn't built for flight hardware — it's about defense supply in general.

4. Configuration management. Both require CM, but differently. AQAP 2110 references ACMP-2100 — the NATO Configuration Management Policy. AS 9100 requires CM at the flight-component level with full lifecycle traceability (including modifications in front-end operations). AS 9100 CM is more detailed and stricter, because it concerns flight hardware where a configuration change can cost an aircraft.

5. Supplier and supply chain control. AS 9100 is stricter: requires cascading aerospace requirements through the entire supply chain, special risk assessments for critical suppliers, mandatory process monitoring at sub-tier vendors. AQAP 2110 is simpler — detailed supplier evaluation with defense criteria, but no mandatory cascade of AQAP downstream.

6. FOD prevention. AS 9100 calls out Foreign Object Debris as a separate discipline — those are bits of debris, tools, metal shavings that can end up in flight hardware and take out an engine or control system. Procedures, training, inspections of assembly zones, FOD containers — all required. AQAP 2110 doesn't carve this out separately; it treats it as part of general process quality.

7. Counterfeit parts prevention. AS 9100 has hard requirements for procedures preventing counterfeit components from entering flight hardware — a dedicated section 8.1.4, supply chain audit, verification of critical part provenance. This became especially relevant after the counterfeit semiconductor scandals of the 2010s. AQAP 2110 doesn't emphasize this — the defense sector relies on its own provenance control systems.

Now the most important part for any Ukrainian manufacturer working at the defense-aerospace intersection. There are four categories where combining both standards isn't optional — it's a qualification requirement.

1. MALE/HALE-class UAV manufacturers. Medium-Altitude Long-Endurance (Bayraktar TB2, MQ-9 Reaper-class) and High-Altitude Long-Endurance (Global Hawk) systems are full-fledged flight hardware, and customers apply both requirement sets: defense (because the contract is military) and aerospace (because the airframe needs airworthiness certification). The cost of getting this wrong is catastrophic — loss of life in the impact zone and total contract write-off. Ukrainian manufacturers moving into this segment (UkrJet, Skyeton TRY3, individual Skyeton projects) are already running into AS 9100 demands from export customers and AQAP 2110 from the MoD.

2. Navigation and avionics equipment manufacturers. GPS receivers, IMUs, on-board computers, communication systems for UAVs and manned aircraft. If the equipment ends up on the airframe — AS 9100 is mandatory. If the customer is defense — AQAP 2110 gets added on top. Manufacturers of drone-swarm communication modules, EW equipment, digital sights with GPS correction often need both.

3. Satcom and space systems. Satellite terminals, antennas, ground stations for defense communications. AS 9100 covers the space industry (through ISO 9001 and IAQG), AQAP 2110 covers defense contracts on these systems. The combination is mandatory for MILSATCOM-segment suppliers.

4. Rocket systems and precision-guided systems. Missile bodies, guidance systems, specialized components. The flight piece (trajectory, aerodynamics, flight control) is AS 9100. The defense contract is AQAP 2110.

For integrating both standards there's an official guidance — IAQG 9137 (Guidance for the Application of AQAP 2110 within a 9100 QMS). It's a 60-page document showing how to incorporate AQAP requirements into an AS 9100 system without double work. The logic is the same as in AQAP 2110 vs ISO 9001 integration: shared base (Annex SL + 7 quality principles of ISO 9001), defense overlay on top. Time and budget savings — 25-35% compared to two separate systems, because AS 9100 already includes most defense-critical blocks (CM, traceability, supplier control), and AQAP just refines the defense specifics.

In practice this means one quality team, one set of top-level documents, defense modules as additional procedures referencing ACMP-2100 and the specific contract requirements.

Not every defense manufacturer needs both standards. There are clear scenarios where one standard covers the whole market reach, and adding the second is wasted money.

AQAP 2110 alone is enough for:

• Small and medium FPV manufacturers (Vyriy, Dovbush, Vampire-series, and others) supplying the MoD and not going beyond ground-launched / ground-recovered systems. An FPV is essentially a one-shot guided munition — airworthiness standards don't apply.
• Manufacturers of unmanned ground vehicles (UGVs) — Termit, Lyut, Wolly, and others. These are ground platforms, AS 9100 is irrelevant.
• Manufacturers of ammunition, munitions, small arms, artillery systems. Defense sector without a flight component.
• Manufacturers of light and medium armored vehicles, special transport vehicles.

AS 9100 alone is enough for:

• Civil aviation — suppliers of components to Airbus, Boeing, Embraer, Bombardier without a defense segment.
• Tier-1 and tier-2 aerospace suppliers who don't chase NATO defense contracts.
• Manufacturers of commercial drones (Mavic-class, agricultural drones) for the civilian market.
• Providers of MRO services for civil aviation.

No quality standard is needed yet for: volunteer deliveries without a formal contract, experimental prototypes, products for individual units without formalization through the DOT. But this is temporary — the market is formalizing fast, and within 12-18 months qualification requirements will spread to most serious suppliers. Better to start preparing now, not a week before the tender.

Let's break the choice into four sequential questions. This is the same decision tree the Ekontrol team uses on a first diagnostic session with a manufacturer.

Question 1: Do you plan defense contracts with NATO-compatible customers? If yes (Ukraine's MoD via DOT, NSPA, national MoDs of Alliance countries, prime defense contractors like Lockheed or Rheinmetall) — AQAP 2110 is mandatory. If no (civil aviation, civilian B2B, non-defense government contracts) — AQAP 2110 isn't needed.

Question 2: Do you make flight hardware or on-board components? Aircraft, medium-and-up class UAVs (from 25 kg MTOW), helicopters, guided-flight rockets, avionics, on-board systems, navigation equipment. If yes — AS 9100 is mandatory. If no (ground vehicles, ground-systems, ammunition, small arms) — AS 9100 isn't needed.

Question 3: Both? If you answered yes to both previous questions — you need both certificates, integrated via IAQG 9137. A combined audit with a certification body that issues both AQAP 2110 and AS 9100 (Bureau Veritas, TÜV NORD, DNV, BSI, or SGS). Savings of 25-35% compared to two separate projects.

Question 4: Starting from zero with no certificate at all? If you don't have a basic quality system, don't start straight with AQAP 2110 or AS 9100. First — ISO 9001 (6-8 months for implementation and certification), then a defense or aerospace overlay. The team needs experience working in a systematized system — without it, parallel implementation of the base and overlay standards fails at Stage 2. More in the complete AQAP 2110 guide.

It's easier to see this as a table by manufacturer type:

Whichever path you pick, before kicking off implementation we run a diagnostic assessment — 3-5 working days, a full gap analysis of system readiness, a realistic budget and timeline. Without this step, planning happens blind.

If you're a drone manufacturer and looking at the wider certification picture — there's a separate piece on drone manufacturer certification with a step-by-step sequence from ISO 9001 to AQAP 2110 and beyond. For a full picture of Ukrainian defense manufacturer certification — the pillar piece defense quality — 3 standards.

On budget — a detailed AQAP 2110 calculation with real numbers for the Ukrainian market is in our piece on AQAP 2110 certification cost. For AS 9100 the order of magnitude is similar, with adjustment for stricter CM and traceability requirements.

As a Bureau Veritas partner in Ukraine, Ekontrol supports management system implementation for both standards and combined audits — the most economical route when you already have a clear contract or tender on an 8-12 month horizon with defense-aerospace requirements at the same time.
