Since 2004 Shield Technologies Corporation of Eagan, Minnesota has provided more than 60,000 Envelop Protective Covers to all branches of the U.S. military. Corrosion prevention cover technology Envelop Protective Covers are used to protect a variety of high value U.S. military equipment to include topside naval weapons, Army ground combat vehicles and both fixed and rotary wing aviation assets. The FY2014 National Defense Authorization Act includes language encouraging the enhanced use of anticorrosion cover systems so more components within DOD can realize the cost savings and readiness benefits of this technology. “Corrosion remains the largest preventable cost to the U.S. Military, a cost which exceeds $23 billion per year,” stated the FY14 NDAA Report.
