TOKYO -- The U.S. and Japan are looking to jointly develop next-generation radar technology that would use Japanese semiconductors to more than double the detection range of the Aegis missile defense system.

This would mark the first major military technology collaboration between the allies since 2014, when Japan relaxed rules that essentially banned exports of weapons and related technologies and set new ones on equipment transfers that make teaming up easier.
