Stalker XE is a long-endurance UAS with quiet propulsion, versatile payloads, and advanced imaging for surveillance, reconnaissance, and data missions.

Lockheed Martin Stalker XE – Long-Endurance UAS for Surveillance and Reconnaissance

The Stalker XE by Lockheed Martin is a sophisticated unmanned aerial system designed for extended duration missions where quiet operation and reliable imaging are critical. With flexible propulsion options including a propane-based fuel cell or battery power, the Stalker XE is ideal for applications in reconnaissance, environmental monitoring, border patrol, and search & rescue.

Key Features and Advantages

1. Extended Flight Endurance

Powered by a fuel cell system, the Stalker XE performs flights up to 8 hours, while battery-only configurations achieve approximately 4 hours of endurance.

2. Quiet, Low-Observable Propulsion

The system is designed to operate with minimal acoustic signature—ideal for stealth or surveillance missions—using a quiet motor and fuel cell or battery power.

3. Moderate Payload Capacity

It supports payloads up to approximately 5.5 lbs (≈2.5 kg), enabling EO/IR sensors or other mission-specific instrumentation.

4. Operational Altitude and Range

Stalker XE operates at ceilings up to 12,000 ft (≈ 3660 m), and offers substantial operational range with fuel cell power. Cruise speeds are around 36-58 km/h, with a maximum speed of about 93 km/h depending on configuration.

5. Versatile Launch and Configuration Options

The aircraft can be launched via hand-throw or rail launcher depending on variant; the XE version typically uses rail or assisted launch. The design allows payload flexibility, including imaging sensors suitable for day/night operations.
