Designed for Operational Reality

Modern maritime security missions demand flexibility.

Across homeland security, naval forces, joint commands, and allied maritime agencies, operational reality does not support an autonomy-only approach.
Many missions require human authority on scene, visible presence, and direct control alongside the advantages of autonomous systems.

Black Line Defense is built for that reality.

Near-Term Deployability

Aligned with current procurement demand and existing operational doctrine.

Mission Sets

Escort & Force Protection

Autonomous and crewed screening and escort of high-value maritime assets, logistics vessels, offshore infrastructure, and mobile task forces. Hull survivability, stability, and escort geometry are informed by decades of real-world operations, reducing common failure modes seen in lightly tested platforms.

Persistent sensing across wide operating areas using collaborative multi-vessel patrols, autonomous sensor cueing, and fleet-level data fusion. Intelligence is relayed efficiently to shore-based or afloat command elements, even in bandwidth-constrained environments.

Crewed and optionally autonomous vessels designed for coastal patrol, interdiction, boarding operations, and port security—missions that require human presence, authority, and rapid decision-making.

Autonomous and hybrid delivery of cargo, sensors, and mission payloads through high-risk waters using adaptive routing, low-signature profiles, and navigation continuity in GPS-degraded or denied environments.

Black Line Command

Hull behavior, power management, and payload performance.

Black Line Command (BLC) is the mission command and control environment for all Black Line Defense platforms—autonomous, crewed, and hybrid.

  • One-to-many operator control
  • Rules-based mission planning
  • Fleet coordination and tasking
  • Live monitoring of vessel health, propulsion, power, and payloads
  • Human-in-the-loop escalation and engagement authority
  • Secure, encrypted communications
  • Operations in GPS-degraded and communications-contested environments
