FET’s defense-class ROVs provide reliable underwater intervention, inspection, search, recovery, and reconnaissance capabilities. Built on decades of subsea engineering expertise, these systems are designed to operate in challenging environments while delivering the precision and flexibility required for military missions.

FET has produced hundreds of manned and unmanned subsea systems for applications ranging from diver support and seabed surveys to submarine rescue support and search-and-recovery operations. Modern platforms incorporate advanced vehicle control technology, high payload capacity, and remote operation capabilities that enable efficient mission execution while reducing risk to personnel.

Applications

• Search and recovery operations
• Underwater inspection and reconnaissance
• Submarine support missions
• Diver support operations
• Seabed survey and infrastructure assessment

Successful underwater operations rely on dependable deployment and recovery equipment. FET’s Dynacon® Launch and Recovery Systems (LARS) provide safe, efficient handling of ROVs, autonomous underwater vehicles (AUVs), sensors, towed systems, and other mission payloads.

Since 1986, Dynacon systems have supported launch and recovery missions around the world. Designed and manufactured in Bryan, Texas, Dynacon LARS solutions combine winches, A-frames, power systems, and handling equipment into fully integrated packages engineered for harsh marine environments. Each system can be tailored to meet specific vessel, mission, and payload requirements, helping defense operators maximize efficiency, safety, and operational readiness.

Capabilities

• Custom winch and handling systems
• A-frames and overboarding systems
• Integrated ROV launch and recovery solutions
• Heave compensation options
• Training, installation, and lifecycle support
• Certification to leading marine standards

VisualSoft Mission Software

Modern defense operations require more than reliable subsea hardware. They demand timely access to mission-critical video, data, and operational intelligence. FET’s VisualSoft software suite provides advanced video recording, data acquisition, processing, and operational visibility capabilities that support subsea missions around the world. VisualSoft is commonly integrated with ROV systems and enables operators to capture, manage, review, and distribute critical mission data with confidence.

Originally developed for subsea inspection and survey operations, VisualSoft has evolved into a robust platform used across the energy, ocean science, and defense sectors. The software supports synchronized video and data acquisition, allowing operators to efficiently review mission events, vehicle data, sensor information, and recorded footage from a single platform. Enhanced streaming and remote connectivity capabilities further enable shore-based personnel to maintain visibility into ongoing operations when required.

VisualSoft complements FET’s submarine rescue systems and ROV platforms by providing the software infrastructure needed to capture operational data, improve situational awareness, and support mission documentation and analysis. Combined with FET’s underwater vehicles and launch and recovery systems, VisualSoft helps deliver a complete subsea solution for defense organizations operating in complex maritime environments.

Capabilities

By combining submarine rescue expertise, advanced ROV technology, and industry-leading launch and recovery systems, FET delivers comprehensive subsea solutions that help defense organizations execute complex missions with confidence. From emergency response and rescue operations to inspection, intervention, and underwater vehicle deployment, FET provides the technology, experience, and support required to operate successfully in demanding maritime environments.
