INTRODUCTION

Various types of shelters are frequently used to contain equipment for modern armies. They are used in a wide variety of applications:

communications weapons control command posts mobile laboratories

in order to contain and protect equipment used to complete these missions.

Shelter design considers the functions and conditions in which they are to be used. Some of these are:

single and multi-purpose use vehicle, pad or ground mounted open or closed to personnel time/mobility configurations

The EMP criteria defined in this document are for general or typical system functions and conditions. The program director using these guidelines needs to ensure that the hardening decisions are compatible with specific system details and possible eventualities of design, production and test. The system manufacturer needs to consider the EMP stress and the system design strengths as he selects hardening

protection and specifies acceptance tests.

This document takes account of EMP hardening at system conception, its

evolution to a hardened prototype system, and identifies production acceptance procedures. The purpose is:

to define EMP hardening in system design, to obtain a hardened prototype system,

to standardize the protection and test.

This document is intended for:

program managers responsible for installing systems into shelters.

contractors and manufacturers of these systems.

persons in charge of the testing of these systems.

This document discusses high altitude EMP as described in AEP-4.

Shelters are described in detail in AEP-19. However, as a part of the balanced hardening concept, other threats are taken into account. This can modify the protection methods and technologies used for EMP hardening. The effects of a low altitude nuclear explosion are not considered, except for their influence on the choices of hardening methods to enable other electromagnetic effects to be taken into account (see chapter 10 for IEMP and SGEMP considerations).
