SA-1 “VANGUARD”
The SA-1 “Vanguard” is a low-observable tactical micro-UAV featuring a flush-ducted quad-rotor carbon chassis engineered for near-silent acoustic operation and minimal radar cross-section in contested urban airspace. Equipped with a forward-facing 4K optical gimbal encircled by an integrated multi-spectral LiDAR and sensor ring, the platform executes real-time target recognition and tracking directly at the edge via onboard autonomous vision software. Designed for both persistent reconnaissance and surgical kinetic interdiction, the airframe incorporates a modular ventral hardpoint for precision-guided micro-munitions with zero payload drag penalty.

Flush Acoustic Nacelles
Serrated Ducted Quad-Rotors
Four 45.0 mm internal-diameter toroidal ducts are molded directly into the blended carbon-composite lifting body. Each duct throat incorporates 9 circumferential boundary-layer trip grooves and 36 axial micro-serrations to break up blade-tip vortices, paired with 5-blade swept counter-rotating micro-rotors for near-silent urban operation.

Onboard Autonomous Compute / Thermal Dissipation
Protected beneath the 2.0 mm RAM-coated dorsal monocoque hull, the A.V.I.A.R.S. neural TPU compute module executes target recognition and multi-sensor fusion in under 5 ms. Passive-active thermal management channels cool air from twin ventral NACA submerged intakes across a 13-fin skived heatsink and out through six 30° rear dorsal exhaust micro-louvers.

Low-Drag Kinetic Interdiction Payload
Engineered for dual-role persistent ISR and surgical kinetic interdiction, the ventral chassis integrates an internal flush weapon bay with a 0.4 mm gasket-sealed quick-release hatch. The modular hardpoint deploys a precision-guided micro-munition featuring an optical/laser seeker dome and 4 cruciform pop-out tail fins with zero aerodynamic drag penalty while stowed.
