WASHINGTON, D.C. — U.S. Sen. Rob Portman announced today that the National Defense Authorization Act passed the Senate and is headed to President Barack Obama for his signature. Portman, R-Ohio, added a provision to the act to add $371 million to authorize research and development and procurement of 81 Stryker vehicles with an upgraded weapon system, most of which would be done at Lima’s Joint Systems Manufacturing Center. The vehicles would serve the only armored brigade in Europe, the 2nd Cavalry Regiment, according to a release from Portman’s office. “My provision to strengthen the Stryker Brigade will not only sent a strong message to our allies in Europe, but also provided our forward deployed soldiers a critically important capability,” Portman said in a statement.
