APS STANAG takes shape

29 November 2017

NATO’s Standardisation Agency has released initial details of the Standardisation Agreement (STANAG) covering active protection systems (APS).

While still a working draft, STANAG 4686, in addition to the accompanying Allied Engineering Publication – AEP-62 – has already defined methodologies for testing soft- and hard-kill APS.

The first volume of STANAG 4686 AEP-62 covers the classification of known incoming projectile threats that an APS might encounter. These include anti-tank guided weapons (ATGWs), rocket-propelled grenades (RPGs), chemical and kinetic energy (CE/KE) tank rounds, and improvised explosive devices (IEDs). Comparisons of data collected on such projectiles include the type of projectile, physical dimensions, arming range, speed profile, and stand-off curve, and codify how such threats are stored in an APS threat library.
