AJP-3.1
NATO joint force commanders, maritime component commanders and their staffs conducting maritime operations
AJP-3.1 is NATO doctrine giving commanders and staffs a common framework to plan, command and conduct maritime operations, agreed to by nations under STANAG 1459.
AJP-3.1 is NATO's Allied Joint Publication on maritime operations: what maritime forces contribute to NATO's core tasks, and how a maritime component commander (MCC) plans, commands and conducts operations at sea, in the air above it, and ashore. Nations record their agreement to use it in STANAG 1459, and AJP-3.1 in turn "derives its authority from and complements" AJP-3, Allied Joint Doctrine for the Conduct of Operations. It is "written for the joint force commander, the maritime component commander, subordinate commanders, adjacent component commanders, and their staffs when conducting maritime operations", and separately offers a weaker "useful framework" to coalitions of partners and non-NATO nations, and "a reference for civilians operating with the maritime component." The document deliberately stays at the operational level: it "does not cover tactical considerations", leaving the detail of maritime tactics to the subordinate Allied Tactical Publications for which AJP-3.1 itself "provides overarching guidance". The current edition is Edition B, Version 1, promulgated 3 April 2025, which "supersedes AJP-3.1, Edition A, Version 1".
The doctrine separates the maritime environment's enduring characteristics - physical, diplomatic, information, military and economic factors - from characteristics that are evolving, such as environmental change, political pressure over maritime claims, coastal urbanisation, and a growing dependency on cyberspace and space. It distinguishes blue-water, green-water and brown-water areas of operation, each with different demands on endurance and logistics.
Maritime forces are described through nine attributes - mobile, versatile and available, resilient, lift capable, a means of posture, sustained reach, a means of leverage, lethal, and expeditionary - which together underpin five roles: providing forward presence, freedom of manoeuvre, projecting power at sea and ashore, contributing to a safe and secure maritime environment, and seizing and holding the initiative. Maritime superiority rests on sea control and sea denial, and a substantial part of the doctrine covers how the maritime component supports, and draws support from, the air, land, special operations and space components.
AJP-3.1 sets out NATO's maritime command structure: Supreme Headquarters Allied Powers Europe, the three standing joint force commands, and Allied Maritime Command (MARCOM) as the theatre maritime component commander, with dedicated commands for submarines, maritime air and surface forces. It covers how nations can attach caveats to forces they allocate to NATO, the officer in tactical command (OTC) and the three defined ways one maritime force supports another, the range of staff roles (including legal, medical, political, cultural, gender and human security advisors), and three methods of control - detailed control, decentralized control, and command by veto - that a commander selects between depending on the operation.
A full chapter works through underwater warfare (antisubmarine warfare, naval mine warfare and mine countermeasures, seabed warfare), above-water warfare (anti-air warfare, integrated air and missile defence, ballistic missile defence, antisurface warfare), maritime information warfare and cyberspace operations, strike warfare, amphibious operations, special operations, and riverine operations. Amphibious operations are grouped into five named types: assault, raid, demonstration, withdrawal, and support to crisis response and other operations.
A separate chapter covers operational art and the sequence of planning activities from initiation and mission analysis through to the concept of operations and the operation plan (OPLAN), then the stages of a joint operation from force generation and deployment through conduct, termination and transition, and identifying lessons. Maritime targeting is treated on its own, including the maritime target nomination list, the maritime prioritized target list and the maritime dynamic target list.
The doctrine's joint-functions chapter covers manoeuvre, fires, command and control (including operating in a denied or degraded communications environment), intelligence, information, sustainment, force protection, and civil-military cooperation. Sustainment is defined as "the comprehensive provision of personnel, logistics, medical, military engineering support, and finance and contract support necessary for Alliance operations and missions", covering afloat support, ashore support, national support, host-nation support, and medical support. Ashore support is coordinated by a shore logistic coordinator "in close cooperation with the joint logistics organization, host nations, nations, and contractors." Civil-military cooperation names the shipping industry as "one of the most significant actors" in the maritime environment, and describes Naval Cooperation and Guidance for Shipping (NCAGS): "The NCAGS institution is the NATO Shipping Centre (NSC) which is the link between military and civilian shipping", offering merchant shipping cooperation, advice and guidance.
The doctrine is specific on a small number of legal points that a reader planning or supporting an operation would need to get right. On detention, it states that "prisoners of war must be interned on premises located on land", meaning "internment on ships is prohibited", with only narrow, temporary exceptions. On casualties at sea, it records that under the Second Geneva Convention "belligerent parties must take all possible measures to search for and collect the wounded, sick, shipwrecked, and dead at sea after engagements." It also addresses gender perspective, human security, personnel recovery, and protection of civilians as considerations that run through planning and conduct rather than standing alone.
AJP-3.1 explicitly excludes tactical considerations, and names no certification, accreditation or notified-body scheme against itself: it describes no mechanism for assessing a company, a product, or a nation against the doctrine. The nearest thing to an evaluation is internal to an operation, not the document. AJP-3.1 states: "The purpose of an operations assessment is to monitor and validate the plan during execution and is a significant part of the decision-making process", run by the maritime component command's own assessment cell.
AJP-3.1 binds NATO commands and, through STANAG 1459, the nations that ratify it - not companies, and nothing here suggests otherwise. Where a company's work actually touches it is narrow: a charter, sustainment or shore-support contract sitting underneath a NATO maritime activity, of the kind the doctrine itself describes when it refers to commercial charters supporting joint sea basing, commercial shipping organisations cooperating with the NATO Shipping Centre, and ashore logistic support coordinated with contractors. For that kind of work, ComplyTrain gives you a place to hold the procedures a contract like that actually asks for: delivery and invoicing records, the training and competency records for the people working under it, and the evidence trail a NATO logistics reviewer or a customer would ask to see - versioned, and easy to produce when asked.
ComplyTrain does not plan or conduct a maritime operation, negotiate a command relationship, or stand in for the NATO planning and coordination process AJP-3.1 describes. That happens between commanders, staffs and nations, not in software.
Which standards and arrangements actually apply to a given contract or activity is set by that contract and the customer's quality clause, not by this page. See the standards explorer for what sits alongside AJP-3.1, and talk to us about the evidence trail behind a support contract.

Thank you. Your list is on its way to your inbox, and we will come back to you on what working with these standards in ComplyTrain involves, usually within one business day.
No. AJP-3.1 binds NATO commands and, through STANAG 1459, the nations that ratify it - not companies. A supplier or contractor meets it only indirectly, where a charter, logistics or support contract built underneath a NATO maritime activity requires something of it.
STANAG 1459 is the agreement by which nations commit to use AJP-3.1; the STANAG records the commitment, and AJP-3.1 is the doctrine itself. A nation ratifies the STANAG, and can do so with reservations, which is a separate step from actually applying the doctrine on an operation.
No. AJP-3.1 is explicit: "This publication does not cover tactical considerations." It focuses on the operational level, and points to a long list of subordinate Allied Tactical Publications, for which it "provides overarching guidance", for tactical detail.
Edition B, Version 1, promulgated 3 April 2025. It is "effective upon receipt and supersedes AJP-3.1, Edition A, Version 1", which was to be destroyed under local document-destruction procedure once the new edition took effect.
No such certification exists. AJP-3.1 names no certification body, notified body or accredited scheme; it is operational doctrine for NATO commanders and staffs, not a standard a company is assessed against.
