Engineering for defense and homeland security
Precision mechanical parts for defense, security and UAV
From high-pressure housings and waterproof enclosures to drone payload and recovery mechanisms — mechanical design, CNC machining, injection molding, surface finishing and volume production — we provide professional design and precision mechanism development for the defense and security industries.
All of our equipment, production and assembly are in Taiwan — nothing is outsourced to or handled by any country of security concern.

Concept · Underwater gliders
Underwater Reconnaissance Gliders and Acoustic Identification Module
Complete concept designs for three underwater reconnaissance gliders and a vessel acoustic identification module: 3D layout, buoyancy engine, attitude control and navigation architecture, with rotating views, exploded views and simulations. Figures are model-based estimates, not yet validated in a tank or at sea.
G1
G1 Shallow-Water Reconnaissance Glider
Long, quiet listening near shore and on the continental shelf: low cost, deployable in numbers
G2
G2 Deep-Water Endurance Glider
Months of passive acoustic monitoring in deep offshore water: low-drag fairing, no moving control surfaces outside
G3
G3 Hybrid-Propulsion Flying-Wing Glider
Seabed and near-bottom reconnaissance: glide to save energy in transit, then run thrusters at constant speed and altitude for imaging
Acoustic
