- The Air Force awarded a contract to Brunswick Corporation for the develop-

m~nt of a basic rigid/expandable shelter requirements with little or no change in

that would fulfill various user shelter design. Furthertore, the

shelter was to be compatible with both air and surface transport criteria.

Extensive However,

testing verified that the spelter meets design details need revision to improve

these two basic criteria. watertightness and reduce

shelter gross weight. The Air Force should adopt the hardwaill expandable

shelter (HEs) as a standard for meting future tactical shelter requirements.

SECTION I

INTRODUCTION

The increased utilization of air-transportable shelters by the Air Force has resulted in a number of different shelter configurations to

-

house specific systems. The repeated research, development, and testing]

*~f

or each new shelter has been both costly and time consauming for the Air

Force. In addition, DOD instruction issued in 1971 stated that future

shelters "..

will conform to ANSI/ISO container specifications to the

extent practicable." These two conditions led to the recoimmendation of

the 1972 Mobility Shelter Workshop that a basic rigi~d/expandable shelter

i

be developed which will fulfill various user requirements with little or no change isn helter design. Furthermore, the shelter must be com-

N

patible with both air and surface transport criteria. Table 1 contains

a complete list of performance criteria.

In December 1973 the Air Force Civil Engineering Center awarded a contract to Brunswick Corporation for development of the hardwall. expandable shelter (lIES). This report identifies the shelter requirements, testing to evaluate its capabilities, and recommendations concerning its utilization.

TABLE 1. PERFORM NCE CRITERIA
