A Hostile Operating Environment
Maritime body armor must contend with an operating environment that is actively destructive to the materials, mechanisms, and comfort systems used in land-based armor. Salt water corrodes metal hardware, degrades adhesive bonds, and accelerates the aging of aramid fibers. The constant presence of moisture, both from sea spray and from the humidity of maritime environments, challenges waterproofing systems and promotes microbial growth in fabric components. And beneath all these material challenges lies the most fundamental problem: body armor that provides excellent ballistic protection on land can drown the person wearing it in water.
The Buoyancy Problem
A standard Level IIIA soft armor vest with front and rear Level IV ceramic plates weighs approximately 25 to 30 pounds. In water, this weight becomes a lethal liability. A fully equipped operator who falls overboard or is forced to abandon a sinking vessel must shed their armor in seconds or face drowning. Standard plate carrier buckles and cummerbund closures, designed for security and retention, can be nearly impossible to release with cold, wet hands while panicked and disoriented in moving water.
Maritime-specific armor addresses buoyancy through two complementary approaches: reducing armor weight using UHMWPE-based materials (which float, having a density of 0.97 g/cm3, less than water), and incorporating rapid-doffing mechanisms that allow the entire armor system to be released in under three seconds with a single action. Quick-release cable systems, pioneered by manufacturers like Point Blank Enterprises, use a central pull handle that simultaneously releases all retention straps, allowing the vest to fall away from the body.
Corrosion Resistance
Every piece of metal hardware on maritime armor is a corrosion vulnerability. Buckles, D-rings, snaps, and adjustment sliders must be made from corrosion-resistant materials: marine-grade stainless steel (316L), anodized aluminum, or high-performance polymers like PA11. Standard carbon steel hardware, even with zinc or cadmium plating, will show visible corrosion within weeks of salt water exposure and can fail completely within months. All fasteners must be designed to function reliably when corroded, wet, and coated with salt deposits.
The ballistic panels themselves require enhanced waterproofing. Standard waterproof panel enclosures may degrade under constant salt spray exposure, allowing moisture to penetrate to the ballistic material. Aramid fibers absorb water, which can reduce V50 velocity by 5 to 15 percent. Maritime armor panels use multi-barrier waterproofing with heat-sealed seams, ultrasonic-welded closures, and salt-resistant materials for the enclosure fabric.
Anti-Spall for Vessel Operations
When a projectile strikes the steel hull of a vessel, it can generate secondary fragmentation (spall) that sprays inward even if the round does not penetrate the hull. This spall can be as lethal as the original projectile. Body armor for vessel crews must provide fragmentation protection across a wider coverage area than typical infantry armor, including side and back coverage against fragments generated by hits to surrounding structure. Spall liners, typically aramid fabric panels mounted on interior bulkhead surfaces, complement personal armor by catching fragments before they reach crew members.
Maritime-Specific Designs
Modern maritime armor systems make deliberate compromises between protection and survivability in water. Float-capable vests integrate closed-cell foam panels that provide limited buoyancy while maintaining ballistic coverage. The foam does not provide enough flotation to keep a fully equipped operator on the surface indefinitely, but it significantly extends survival time and reduces the effort required to stay afloat while shedding equipment. Some systems integrate with personal flotation devices (PFDs), allowing the PFD to be worn over or integrated into the armor carrier.
GoatArma™ Maritime Configuration
GoatArma™'s CAPRASKIN™ is available in a maritime configuration that replaces standard hardware with PA11 polymer buckles, adds multi-barrier panel waterproofing, and integrates a single-pull quick-release mechanism. The modular architecture allows operators to configure the maritime system with PE-only plates (which float) for riverine operations or ceramic plates for open-water vessel operations where the threat profile demands higher protection. The AI fit verification system includes a maritime mode that confirms the quick-release mechanism is properly engaged and functional before the operator moves to the operational area.
