STANAG 4375
National drop-testing authorities in NATO nations, and defence suppliers working to a contract that invokes AOP-4375
STANAG 4375 is NATO's agreement committing member nations to implement AOP-4375, the Allied Ordnance Publication setting safety drop test procedures for munitions.
STANAG 4375 is a NATO Standardization Agreement, currently Edition 4, dated 17 July 2024. It is not a technical specification. It is the agreement by which NATO nations commit to accept and implement Allied Ordnance Publication AOP-4375, Edition A, the document that actually sets out safety drop test procedures for munitions. Read on its own, STANAG 4375 names no drop height, no drop orientation and no pass or fail threshold - that detail lives inside AOP-4375, not inside this letter of promulgation. Its own text frames the point plainly: participating nations agree "that AOP-4375 provides a suitable basis for assessing the reaction, if any, of munitions systems to accidental drops."
STANAG 4375 binds nations, not organisations directly. Its implementation clause says the STANAG "is considered implemented when a nation has updated its national policy regarding safety drop testing of munitions to incorporate the tests of AOP-4375." Ratification and implementation are separate steps, and the document invites nations that have not yet reported their position to "advise the NSO of their intention regarding its ratification and implementation." So "is STANAG 4375 mandatory" has no single answer: it depends on whether a given nation has ratified and implemented it, and, for a supplier, on whether a specific contract or tender names AOP-4375 as a result.
Under "Agreement," participating nations agree to implement AOP-4375, Edition A. Under "Implementation of the agreement," ratifying nations are required to update their national munition drop-testing policy to be in accordance with AOP-4375, update their national drop-testing procedures and guidance to reflect what AOP-4375 gives, and update their national drop-testing documentation to incorporate AOP-4375's own definitions. Allies and NATO bodies must then report implementation details through NATO's electronic reporting tool, and partner nations are invited to do the same. None of this is written as a duty on a supplier; every duty in the text runs to "nations" or "ratifying nations."
The distinction matters because a reader who only has STANAG 4375 in hand does not yet have a test procedure to work to. The stated aim is "to accept the Allied Ordnance Publication AOP-4375 which enables nations to collaborate in effectively implementing and conducting safety drop testing of munitions" - everything a test engineer needs sits inside that acceptance, not in the promulgation letter itself. STANAG 4375 supersedes Edition 3, dated 15 June 2010.
STANAG 4375 names no assessment or certification scheme of its own. Its only stated check is that the STANAG itself "is to be reviewed in accordance with AAP-03," a periodic review of whether the agreement is still current, recorded in the NSDD, not an audit of any organisation or product. The cover also names two related documents that sit alongside the agreement rather than inside it: STANAG 4297, covering the assessment of safety and suitability for service of non-nuclear munitions (AOP-15), and STANAG 4370, covering environmental testing (AECTP-100 to AECTP-600). Neither is a requirement of STANAG 4375; both are pointers to standards a munitions programme is likely to meet alongside it.
STANAG 4375 itself gives a supplier nothing to implement in software: it is an agreement between nations, and the drop-test procedures sit in AOP-4375. Where ComplyTrain fits is the paperwork trail behind whatever AOP-4375 requirements a contract actually invokes: a documented drop-test and qualification plan tied to the contract's requirements, controlled procedures for how the testing is run, training records showing the people executing the programme are competent, and a record of every test outcome that a customer's quality assurance representative can check against the requirement it was meant to satisfy.
ComplyTrain does not drop a munition, build a drop rig, or judge which AOP-4375 conditions apply to a given item. That engineering and test-house judgement is carried out by people qualified to do it, not by a compliance platform on a customer's behalf. What applies to a specific programme is set by the contract and the customer's quality clause, not by this page. Our standards explorer shows what else sits alongside STANAG 4375 - if you are weighing up what a tender actually requires, we're glad to talk it through.

Not on its own. A STANAG binds a nation once that nation has ratified and implemented it, and it reaches a supplier only when a contract or tender names AOP-4375. Whether it applies to a given programme is a question for the contract, not for this page.
STANAG 4375 is the cover agreement: it commits nations to implement AOP-4375 but contains no drop test procedures itself. AOP-4375 is the Allied Ordnance Publication that actually sets out the safety drop test procedures for munitions.
No. STANAG 4375 describes no certification or accreditation scheme. Its only stated check is a periodic review of the agreement's own currency under AAP-03. NATO does not certify organisations or products against a STANAG.
Edition 4, dated 17 July 2024, which supersedes Edition 3 of 15 June 2010.
No. This cover agreement names no drop height, orientation or pass/fail threshold. Those details belong to AOP-4375, the publication STANAG 4375 brings into force.
