AASTP-05
Operational Commanders and Explosives Safety Officers running ammunition storage, maintenance and transport on deployed NATO missions
NATO guidelines for storing, maintaining and transporting ammunition on deployed missions, used when a permanent AASTP-01 depot is not available and licensed at national rather than NATO level.
AASTP-05, NATO Guidelines for the Storage, Maintenance and Transport of Ammunition on Deployed Missions or Operations, is the Allied Ammunition Storage and Transport Publication that covers temporary, threat-environment munitions facilities. Nations' agreement to use it is recorded in STANAG 4657, and the current text, Edition B Version 1, was promulgated in July 2024. It is written for use by the Operational Commander's Explosives Safety Officer (ESO), and it sets out how a deployed force stores, looks after and moves munitions once a purpose-built, permanent depot of the kind AASTP-01 governs cannot be provided in time.
AASTP-05 exists specifically because AASTP-01's permanent-facility standards do not fit a deployment. Where AASTP-01 sets standards for permanent, long-term facilities, AASTP-05 sets standards for more temporary facilities that have to operate in a threat environment, so it applies once AASTP-01-suitable infrastructure cannot be built or installed in time and a field depot has to be used instead. It draws directly on AASTP-01's hazard classification and quantity-distance groundwork rather than restating it, and it points to AASTP-03 for hazard classification and to AASTP-04 for the detailed methodology behind the risk analysis it summarises for field use. The transport chapter defers in the same way to the Allied Movement Publication that now carries NATO's dangerous goods transport rules, rather than duplicating them here.
The document's own reference point is the Operational Commander's Explosives Safety Officer, who manages the day-to-day explosives safety programme and advises the Commander on all explosives safety matters. The Operational Commander carries ultimate accountability for balancing safety against operational need, appoints the ESO, and decides deviations and risk acceptance. Where several nations share a base, the document requires them to stand up an Explosives Safety Board, chaired by a senior officer and attended by a representative from every co-located nation, to agree shared safety criteria and coordinate land use, construction and licensing decisions across the compound.
The trigger for applying AASTP-05 is the absence of a permanent facility, not a fixed date. It belongs at the planning and reconnaissance stage of a deployment, before munitions arrive, and a separate part of the document addresses the other end of a mission: when an operation concludes, the same guidelines apply again to the consolidation, storage, transport, maintenance, retrograde and disposal stages of a drawdown.
AASTP-05 reads as much as a governance framework as a technical manual. Before a site is used, it expects a Memorandum of Understanding with the host nation or partners, an approved site plan document, an explosives licence, and a record of any approved deviations, each reviewed by the appropriate authority. Before the Operational Commander deviates from the guidelines, relevant specialists must be consulted and that advice documented; where a requirement genuinely cannot be met, a risk assessment is required and any deviation needs formal approval. NATO itself runs no explosives safety or licensing organisation: those matters are carried out at national level, which is also why destruction of munitions, for example, has to follow both AASTP-01 and the national regulations that govern the operation.
The manual sets out two different storage regimes matched to how settled a position is. A Field Distance regime covers storage expected to last through most of a deployment. A Transition Distance regime is deliberately less protective and is meant only for the short period entering or leaving a theatre: the document is explicit that storage under this regime carries an inherent risk of total loss of munitions, and that a transitional site can no longer be treated as temporary after three months of use, at which point storage has to move to the Field Distance regime or to AASTP-01's permanent-facility criteria.
Where neither regime's requirements can be met at all, a five-step risk management process runs from hazard identification through analysis, a control plan, formal approval and ongoing tracking, producing what the document calls an Explosives Safety Case, presented to the authority accepting the residual risk, most often the Operational Commander. A nation that declines to take part in that process does not avoid the outcome: NATO's own risk-decision requirements still apply, made instead by a delegated general or flag officer, with the reasons for non-participation recorded.
AASTP-05 names no certification scheme, and nothing in it describes an outside body certifying a company, a site or a nation against it. What it describes instead is command oversight: scheduled explosives safety inspections by the responsible headquarters, ongoing review by the Explosives Safety Board in a multinational setting, and, where the storage regime cannot be met, the Explosives Safety Case and risk decision an approving authority signs off on. Munitions accidents are reported through a system the national authority or organisation responsible for the munitions has to put in place, and investigations are led by someone that authority appoints. Separately, every NATO base that issues munitions to personnel has to run a Munitions Amnesty Program, intended to recover munitions that have ended up outside the normal supply chain. None of this is third-party certification or a notified-body assessment; it is internal command and national administrative control.
AASTP-05 is an operational document, not a management system a company gets audited against, and the work it describes, siting a compound, running an Explosives Safety Board, keeping a site licence current, briefing an Explosives Safety Case, happens in the field, not in software. What a company supporting a deployed ammunition storage, maintenance or transport contract needs is somewhere to hold the paper trail the document assumes exists: the Memorandum of Understanding, the site plan document and its approvals, the explosives licence and any recorded deviations, the standard operating procedures a compound runs to, training records for people appointed as ESO or Fire Protection Officer, and the record of an accident report or an Explosives Safety Case once one is raised, kept together and auditable instead of scattered across a shared drive.
ComplyTrain does not decide whether a munitions area meets AASTP-05's storage regimes, does not calculate a required distance, does not sit on an Explosives Safety Board, and does not accept risk on anyone's behalf. Those decisions belong to the Operational Commander, the appointed ESO, the Explosives Safety Board where one exists, and the national authority that licenses the site. What tier of NATO ammunition safety guidance a specific contract requires, and how a customer's quality clause expects it evidenced, is set by that contract and the customer, not by a vendor. If you are supporting a deployed ammunition storage, maintenance or transport contract, the standards explorer shows what else sits in the AASTP family, and we are glad to talk through how you would evidence the work.

It binds through STANAG 4657, the agreement recording NATO nations' commitment to use it. NATO runs no licensing body of its own; explosives site plans, licences and deviations are handled at national level, so whether and how AASTP-05 applies to a specific compound or contract is a question for the national regulations and the contract governing that operation, not a general answer.
No. AASTP-01 sets standards for permanent, long-term munitions facilities, and AASTP-05 complements it by covering temporary facilities operating in a threat environment, used specifically when AASTP-01-suitable infrastructure cannot be built or installed in time. AASTP-05's own criteria are built on AASTP-01's hazard classification and quantity-distance groundwork rather than replacing it.
No. The document names no certification scheme and no accredited or notified body. What it describes is command oversight and national administrative control: scheduled explosives safety inspections, Explosives Safety Board review in multinational settings, and a documented risk decision where the storage regime cannot be met. None of that is a certificate.
Field Distances apply to storage expected to last through most of a deployment. Transition Distances are a deliberately less protective regime meant only for the short period entering or leaving a theatre, carrying, in the document's own words, an inherent risk of total loss of munitions, and a transitional site cannot be treated as temporary once it has been in use for more than three months.
