Navy, Military Sealift Command, Unites States Coast Guard, and Defense Logistics Agency activities utilize HEDRS to research HM&E equipment. Access to HEDRS is limited to Government employees and specific Government contractors, for whom the Government Contracting Officer Representative (COR) validates the access request. HEDRS is considered unclassified and is For Official Use Only. The user must be aware that HEDRS data can be correlated in such a manner that it would be considered sensitive.
