Mission capabilities

Operate where others cannot.

Public-facing capability categories remain intentionally limited. Expanded technical information is available only through qualified government and partner channels.

ISR & Surveillance

Persistent sensing, observation, and maritime-domain awareness.

Target Tracking

Mission-specific identification, tracking, and authorized target support.

Secure Networking

Controlled communications, mission updates, and systems integration.

AI-Assisted Autonomy

Mission execution within authorized parameters and defined objectives.

Undersea Effects

Public-safe description of authorized offensive and defensive mission applications.

Biomimetic Platforms

Hydrodynamic forms inspired by efficient marine movement.

America First Manufacturing

American engineered.
American sourced. American built.

Every I2D platform is governed by a domestic-source mandate: U.S. design, U.S. engineering, U.S. manufacturing, and no foreign components or subsystems.
