AI Overview
The Navy seeks novel anti-fouling coatings for submarine topsides that prevent marine growth without being slippery or toxic to crew. The solution must remain effective for 6-8 years, survive alternating wet/dry conditions, and withstand foot traffic while maintaining propulsion efficiency.
This summary is AI-generated from the official solicitation.
Key Details
Official Description
Anti-fouling paints and coatings are applied to submarines, ship hulls, and acoustic sensors to inhibit the growth and accumulation of unwanted marine life (“biofouling”; e.g., barnacles, tube worms, algae biofilms, etc.). Biofouling increases surface drag and creates noisy flow conditions. Some anti-fouling materials contain poisons (biocides) to discourage the unwanted marine growth while others (foul release type coatings) form extremely slippery surfaces that prevent marine organisms from at...

Submarine Top-side Anti-Slip Anti-Foulant
Q1 received a comprehensive new answer addressing: (1) coating application over existing systems allowed if performance maintained; (2) existing specs expected unless radically different; (3) 50/50 submerged/surfaced target; (4) application by manufacturers and shipyards with quick-cure preference; (5) top-coat for above-waterline surfaces; (6) human traffic durability expected, damage touch-ups as-needed.
Submarine Top-side Anti-Slip Anti-Foulant
Added comprehensive Q1 addressing application method, performance standards (MIL-PRF-24667 traction vs. new envelope), hydrodynamic drag limits, service life duty cycles, shipyard application constraints, acoustic zone overlap, and mechanical traffic loading specifications. Q2 and Q3 renumbered without content changes.
Submarine Top-side Anti-Slip Anti-Foulant
Added 3 new Q&As from NUWC Technical Points of Contact specifying existing paint/coating standards: MIL-PRF-24647 (underwater hulls), MIL-DTL-24441/MIL-PRF-23236 (topside surfaces), and MIL-PRF-24667 (non-skid walking areas).

# Summary This clarification modifies the biofouling prevention requirement for submarine surfaces: the protective solution must remain bonded for 6-8 years and prevent biofouling during the system's service life, but interim cleaning is permitted and expected.
