Offshore Patrol Vessels (OPVs) have gained in stature in the Indo-Pacific region as maritime security has come sharply into focus for governments. OPVs are operated by a mix of naval and coastguard forces although this depends on each country’s maritime security structure. Dr Collin Koh Swee Lean, research fellow at RSIS said, “The biggest issue has always been funding and this is related to the second biggest: inter-service problems. This is often a barrier to establishing a maritime security architecture, which has an impact downstream about how they allocate resources more optimally.”
