More on the tactical capabilities Adding a small 30 HP engine with propeller to the HAHO Pod adds additional strategic capabilities. The engine provides propulsion for extended and ascending flight. The system can take off again once landed, being airborne in 50-150 feet; a paved runway is not required.
It could be parachuted from an aircraft and travel around on the ground, becoming airborne when necessary by redeploying its canopy. It will travel at about 46.3 kilometres per hour and consume 7.5 litres of fuel per hour, the company says.
