Following a flurry of reports in December predicting the Navy's $500 million electromagnetic railgun experiment was dead on arrival, the chief of Naval Operations told lawmakers this week that the death of the program was greatly exaggerated."[We are] fully invested in railgun; we continue to test it," Adm. John Richardson told the House Appropriations subcommittee on defense during a Wednesday hearing on Navy and Marine Corps budget issues. "We've demonstrated it at lower firing rates and ... shorter ranges. Now we have to do the engineering to, sort of, crank it up and get it at the designated firing rates, at the 80- to 100-mile range."Richardson was responding to a question from Rep. Tim Ryan, D-Ohio, who expressed concern about the proven capability of the Navy's railgun weapon, which has yet to leave its test site at Naval Surface Warfare Center Dahlgren Division, Virginia.
