Ghost Gliders: Spanish Narco-Submarines
This open source intelligence (OSINT) report documents the development of narco-submarines in Spanish waters. These vessels, known as LPVs (Low Profile Vessels) or alternatively SPSS (Self-Propelled Semi-Submersible) vessels, are proliferating globally. These 'narco-submarines' now include three types: Fully Submersible Vessels (FSVs), Low Profile Vessels (LPVs), and hybrid Low Profile Vessels/Go-Fast Vessels (LPV/GFVs).
