Maritime Platforms Built Around the Mission

Speed, durability, payload flexibility, and mission-ready integration — from fast patrol boats to long-endurance unmanned surface vessels. Every platform is configured to serve the mission, not the other way around.

High-Speed Boats for Patrol, Response, and Security

Gulf Coast Tactical builds manned patrol vessels for defense, security, and government operators who need dependable performance in demanding coastal and nearshore environments. With proven designs originally developed by Sewart Seacraft and enhanced with modern mission systems, these platforms are built for speed, endurance, crew effectiveness, and mission-ready integration.

Configured around the operating profile, Gulf Coast Tactical patrol craft can support coastal patrol, maritime security, interdiction, force protection, ISR support, and rapid response missions.

Unmanned Surface Vessels Autonomous, Payload-Ready USVs for any-Mission

When the mission calls for endurance, autonomy, and reduced operator exposure, Gulf Coast Tactical fields rugged aluminum and composite USVs. The autonomy supports manual and fully autonomous control — with GNSS-based navigation, waypoint execution, obstacle avoidance, loitering, geo-fencing, convoy-follow, and multi-vessel group control.

The GC-15, GC-18, and GC-20 are fully vacuum-infused, wood-free composite monohulls built to ISO 12215-5 scantlings — engineered for strength, durability, and low-maintenance operation at speed. Each can run manned, optionally manned, or autonomous, and integrates navigation, radar, radios, cameras, autonomy, and mission payloads.
