Air defense system will protect small cities

A compact air defense system, which can be deployed to any part of the world on virtually a moment´s notice, has been produced. Air defense systems have already been installed in 10 major cities, but the new system, called Birdie, will take care of defense co-ordination in the smaller metropolitan areas and around vital defense bases. It is built by the Martin Co., and gets its name from the term “battery integration and radar display equipment.”
