The defense manufacturing supply chain is critical to both the U.S. economy and national security. Support is needed for emerging technologies such as directed-energy weapons, hypersonics and cybersecurity, all of which are vital to national defense. While challenges exist, there have been remarkable successes due to the MEP National Network’sTM dedication to assist small and medium-sized manufacturers across the U.S. and in Puerto Rico. Manufacturers assisted have included those that supply a material, component or subsytem used in a defense or national security system. The Network continues to provide support in building a robust defense supply chain.
