The FP-7 ballistic missile has been used in combat. Now it needs to be designed and put into use with a cluster warhead - Point of Fire co-founder and lead designer Dennis Stillerman According to Stillerman, the FP-7 is cheaper than ATACMS, but it is still an expensive missile. "There is no point in delivering 200 kg over 300 km for $600,000. The same warhead was carried by the FP-2 UAV," Stillerman said. He added that until the FP-7 with a cluster warhead is promoted and adopted into service, the use of a missile with a high-explosive warhead is not economically viable.
