1.1.3. The proposal shall include an option to provide a separate Ammunition Conditioning Chamber

(ACC). The Government may exercise this option prior to delivery of the chamber, or after installation of WFC SMEE equipment.

1.2. Background

U.S. Army Yuma Proving Ground is located near the Arizona‐California border, adjacent to the Colorado River, approximately 24 miles north of the city of Yuma (pop 87,000), Arizona. YPG conducts tests on medium and long range artillery, aircraft target acquisition equipment and armament, armored and wheeled vehicles, a variety of munitions, and personnel and supply parachute systems; and is the Army's center for desert natural environment testing as well as the management of cold weather and tropic testing. At 1300, square miles, YPG is one of the largest military installations in the world, and provides facilities, instrumentation, and expertise to test equipment for the Department of Defense, other government agencies, foreign entities, and private industry customers.

Yuma has subtropical desert environment, Köppen climate classification: BWh. The SMEE installation site is at the existing WFC test site approximately 400 feet above sea level. The equipment will be installed outdoors and subjected to local weather conditions including rain, wind, solar effects, temperature, and dust storms. On average 118 days per year exceed 100°F. The record high temperature is 124°F, and the record low is 22°F.

YTC’s (Yuma Test Center) GP‐5 (Gun Position 5) Weapons Firing Chamber has the capability to perform environmental testing while maintaining the ability to directly and indirectly fire large caliber weapon systems.

The WFC was manufactured in 1992 and consists of a large, earth covered steel culvert. The chamber test volume is approximately 13,000ft3, includes an earthen floor for emplacing artillery, and is accessed via a large, insulated rolling door. Weapons are fired from an adjustable, insulated firing port (reference Appendix A – Existing

Equipment).
