STANAG 4145

STANAG 4145 nuclear hardening criteria for land materiel

Makers and testers of land military materiel required to demonstrate nuclear survivability, and the national acceptance authorities that oversee that testing.

STANAG 4145 sets NATO's nuclear hardening criteria for armed forces material (land), AEP-04 edition B. NATO has not released it publicly; this page describes it from public NATO publications that cite it.

NATO has not released this STANAG publicly. It is NATO UNCLASSIFIED, and organisations that need it obtain it through their national standardization authority.

What it is

STANAG 4145 is the NATO Standardization Agreement on nuclear hardening criteria for armed forces material (land). The current edition, edition 3, was promulgated in August 2026 under CNAD, AC/225 NAAG, JCBRND CDG, and covers AEP-04 edition B.

NATO has not released STANAG 4145 publicly, so this page describes it from public NATO publications that cite it.

Where it is cited

The public NATO publications below cite it under the title Nuclear Survivability Criteria for Armed Forces Materiel and Installations. AMedP-7.5 lists AEP-4 (STANAG 4145) of September 1996 and marks it NATO CONFIDENTIAL.

AECTP-250 separates electromagnetic pulse into high-altitude EMP (HEMP), source-region EMP (SREMP) and system-generated EMP (SGEMP), and states that the classified definitions for HEMP and SREMP are in STANAG 4145.

In AECTP-500, for ships, STANAG 4145 "describes in detail the waveform of the test impulse" used in the nuclear EMP test. For land systems, the test uses the unclassified EMP waveform of AECTP 256 and AECTP 501 and, if the National Acceptance Authority specifies it, also the classified HEMP and SREMP waveform requirements in STANAG 4145.

AMedP-7.5 names AEP-4 as a source of blast shielding protection-factor values and does not reproduce them, citing classification and distribution limitations.

AOP-15 refers to STANAG 4145 and AEP-04 for the threat level where a munition must withstand air blast, thermal or ionizing radiation, or initial nuclear radiation. STANAG 4599 lists the effects of a nuclear explosion, EMP, initial nuclear radiation, air blast and thermal radiation, as defined in STANAG 4145 (AEP-4) and AEP-22.

Put STANAG 4145 on a system that keeps the evidence

Documents, training, risks and evidence in one place, with the trail an auditor asks for.

How we help

A supplier bound by STANAG 4145 through a contract holds the obtained text through its national authority. In ComplyTrain you record the requirements that apply to you as your own requirements, give each an owner, and keep the evidence that shows you meet them against each one.
