Project Background
• Contacted by one of our partners, Certex in Houston, TX.
• Lifting a new multi-million dollar drone developed by the Navy.
• New electromagnetic testing process for the Navy.
• The drone will be suspended for periods of time in a special testing facility.
• Due to the types of testing to be performed, an alternative to steel had to be identified.

• Drone usage is increasing worldwide using ISR
(Intelligence surveillance and Reconnaissance) System
Technology.
• The Triton Drone has improved capabilities such as
endurance, range, altitude, and stability to the Navy’s
already existing technology.
• The Triton Drone is a UAV (Unmanned Aircraft Vehicle).
Current UAV systems are the size of an insect to the size
of a 737 aircraft.
• The Triton Drone UAV is capable of collecting data and
loiter over a specific area for long periods of time to
collect this data.
