MAINTENANCE LIGHT
Built on TKO’s patented electric drivetrain and motor technology, enabling a truly maintenance-light regime, long shelf life and rapid deployability.
ATTRITABLE
Designed for low unit cost, so SD250s can be fielded in numbers.
Pricing on request.
LOW SIGNATURE
TKO’s electric motors and drivetrains incorporate passive cooling technology to minimise thermal emissions and acoustic signature, enabling a reduced operational signature.
