The US Air Force is now seeking suppliers for a “counter ultra light aircraft/paratrooper system” (CULAPS, for short). According to the solicitation, here’s the basic idea:
The CULAPS system is envisaged as a lightweight net aimed and firedfrom the ground that envelopes the target and thereby removes thetarget’s lift bringing it to the ground. The system should belightweight (man/vehicle portable) and have an effective vertical rangeof greater than 500 feet. An attribute of the system should include thepotential for linking the firing system to a sensor system forautomated remote operation.
If you are an interested supplier — or if you are, say, Spiderman — you have until 20 February to submit your response.
