This article provides an exhaustive breakdown of STANAG 4367, including its history, technical specifications, testing methodologies, and its critical role in modern armoured vehicle procurement.
Note: The exact charge mass can vary depending on the explosive type (e.g., TNT, C-4, Composition B). Conversion factors (TNT equivalency) are defined within the standard.
Unlike its cousin, STANAG 4569 (which covers ballistic and artillery fragmentation protection), STANAG 4367 focuses exclusively on the blast effects of landmines and IEDs that detonate directly beneath a vehicle’s hull. The agreement provides a standardized way to measure and classify the level of protection afforded to: stanag 4367
(first widely adopted in the mid-2000s, with revisions such as AEP-55) was developed by the NATO Army Armaments Group (NAAG) to harmonize these conflicting approaches. It effectively adopted and refined blast test methodologies from the UK, US, and Germany into a single, cohesive standard.
| Feature | STANAG 4367 | STANAG 4569 | | :--- | :--- | :--- | | | Landmines & IEDs under the belly | Bullets, shrapnel, artillery fragments | | Direction | From below (vertical impulse) | From sides, front, top (horizontal/lateral) | | Test Media | Explosive charges (kg of TNT) | Projectiles (7.62mm, 14.5mm) and shell fragments | | Failure Mode | Floor buckling, spine compression | Penetration of armour, spall | | Example Level | Level 2a (6 kg TNT under hull) | Level 4 (14.5mm API at 200m) | This article provides an exhaustive breakdown of STANAG
A common point of confusion is the difference between (mine blast under hull) and STANAG 4569 (ballistic and artillery fragmentation).
NATO forces increasingly relied on wheeled armoured personnel carriers (APCs) and mine-resistant ambush-protected (MRAP) vehicles. These vehicles were vulnerable to smaller, anti-personnel mines (like the Italian VS-50 or Russian OZM) and homemade IEDs containing artillery shells. Unlike its cousin, STANAG 4569 (which covers ballistic
For engineers, it is a rigorous design framework. For procurement officers, it is a non-negotiable requirement. And for NATO, it ensures that a Polish BWP-1, a German Boxer, and a US JLTV can operate together with a shared, quantifiable understanding of mine protection.
As of the mid-2020s, STANAG 4367 continues to evolve. The most current technical guidance is found in (Edition 4 or later). Future revisions are expected to address:
To combat this threat, standardization is not just a matter of logistics—it is a matter of life and death. Enter (Standardization Agreement 4367). Officially titled "Procedures for the Assessment of Protection Levels of Crew and Equipment of Armoured Vehicles Against Explosive Devices Detonating Underneath the Hull," STANAG 4367 is the cornerstone document that defines how NATO tests and rates a military vehicle’s ability to survive a mine blast.
