The Navy ship anchor chain is a heavy-duty, high-strength steel chain used to secure vessels to the seabed. It consists of interconnected links designed to withstand immense tension and corrosion. The chain's length and thickness vary based on the ship's size and anchoring requirements.

Size: Typically ranges from 1.5 inches to 5 inches in diameter, depending on vessel size.

Grade: Common grades include Grade 2, Grade 3, and High-Test (HT) for higher strength.

Viscosity: Not applicable; anchor chains are solid metal links.

Buoyancy: Negligible; chains are heavy and designed to sink.

Material: Made from high-strength carbon steel or alloy steel, often galvanized for corrosion resistance.

Length: Standard shots are 15 fathoms (90 feet) per link, with total length varying by ship size.

Breaking Load: Varies by grade and size, e.g., Grade 3 chains have higher tensile strength than Grade 2.

Weight: Approximately 40-200 lbs per fathom, depending on diameter and material.

Finish: Hot-dip galvanized or painted for durability in marine environments.

Certification: Meets standards like ABS, DNV, or Lloyd's Register for maritime use.
