# Lockheed Martin Indago 3T – Tethered VTOL for Persistent ISR Missions
The Indago 3T from Lockheed Martin is a tethered vertical take-off and landing (VTOL) quadcopter designed for continuous surveillance, situational awareness, and intelligence gathering. With its tethered power supply, it achieves extended on-station endurance, paired with advanced EO/IR payloads and secure data links—making it ideal for persistent monitoring over high-value locations, critical infrastructure, and tactical operations.
Using a 50-meter tether, the Indago 3T maintains constant power, enabling uninterrupted surveillance without battery limitations. This ensures reliable fixed-point monitoring over extended periods.
Supports electro-optical (EO), infrared (IR), and communications relay payloads. The Noctis IR sensor provides thermal imaging, while EO sensors deliver high-resolution visuals for detailed situational awareness.
Foldable into a compact footprint (≈12×9×7 in), weighing approximately 1.995 kg (≈4.4 lbs), the Indago 3T is easy to transport and deploy. Assembly is tool-free and optimized for rapid setup in rugged environments.
Supports encrypted data links and real-time video or data streaming via the tethered connection. Designed for operations requiring secure communications and data integrity.
With indefinite flight capability via tethered power, Indago 3T is ideal for border security, base protection, event monitoring, and infrastructure surveillance. Its persistent flight and multi-mode sensors deliver constant situational insight.
