SPELCO, the Special Parachute and Logistics Consortium, produces a variety of parachute systems, helmets, oxygen supplies and other gear and services, but their most eye-catching project is the Gryphon Next Generation Parachute System, a wingsuit for airborne assault:
This is described as a modular upgrade for parachute systems for use in “high-altitude, high-opening” jump missions, typically carried out by Special Forces. This 6-foot wing gives a glide ratio of 5:1, which means that a drop from 30,000 feet will allow you to glide about 30 miles. The makers estimate that this would take around 15 minutes, giving an average speed of about 60 miles an hour.“All equipment is hidden in a lifting body optimized for stealth, the radar-signature is extremely low,” says the Gryphon data sheet (PDF). “Detection of incoming Gryphon soldiers by airborne or ground radar will be extremely difficult.”
Gryphon has a guidance system and heads-up display navigation. Best of all, the company are looking at an option for bolting on small engines similar to those used in Yves Rossy’s setup. These will increase the range to more than 60 miles, but will also make it possible to cover long distances from low altitude so that the entire mission can be more stealthy.
