The MIL-R-77123 specification, also associated with MIL-DTL-77123, covers technical rope made from high-performance synthetic fibres for military and aerospace logistics applications.
Technical characteristics
Material: Nylon or polyester according to the applicable product configuration. Braided or laid construction: Construction varies by type and is selected to provide controlled strength and handling. Environmental durability: Synthetic fibres provide useful resistance to moisture, abrasion and outdoor exposure. Operational flexibility: The rope is intended to remain practical to handle across demanding field conditions.
MIL-C-5040 is a small, lightweight nylon cord for personal equipment and parachute use. MIL-R-77123 addresses heavier technical rope applications with larger dimensions and higher load ranges.
