MARITIME BLAST MITIGATION SERIES
Your Hull Is Steel. Against a Blast, That's Not Enough.
33kg of TNT. One full-scale ship test. Here's what the research proved.
Limpet Mines
Three Threats. One Unprotected Hull
1.5–5kg explosive. State-actor weapon of choice. Gulf since 2019.
Small Boat IEDs
200–400kg. USS Cole. The attack that rewrote naval doctrine
Anti-Ship Missiles & Drones
80+ vessels targeted. Red Sea. 2023–2025.
15–25mm Standard Tanker Hull Thickness
Against a shaped charge — it's not enough.
Two Waves. One Hull. Spall Kills.
Exterior
Compressive wave strikes here first
Wave 01 Compressive Pressure
Strike
Initial blast wave hits exterior hull face with massive force
Result: Spallation
Interior
Tension wave reflects here pulls apart
Wave 02 Tension
Reflected Rupture
Milliseconds later — wave reflects inward and tries to pull steel apart
⚠️ Steel fragments eject inward at lethal velocity — into crew spaces, pump rooms, engine rooms.
The hull survived. The crew didn't.
TEST SETUP
33kg of TNT. One Real Ship.
Here's What Happened.
Full-scale vessel approximately 50m × 9m. Half the hull bottom coated with polyurea (8mm steel + 24mm polyurea). Half bare steel. Same explosion.

Polyurea Moves. That's the Difference.
Mechanism 01 SHOCK WAVE SPLITTING
01 Phase-separated microstructure breaks blast energy into a two-wave system, dissipating force during transition.
Mechanism 02 IRREVERSIBLE DENSIFICATION
02 Hard domains absorb energy through hydrogen bond reorganization under shock loading.
Mechanism 03 ELASTIC CONTAINMENT
03 400–800%+ elongation. The membrane stretches and contains fragmentation through pressure and rebound phases.
