About BAE Systems and the U.S. Navy's Strategic Systems Programs (SSP)
Our organization has supported the U.S. Navy's Strategic Systems Programs (SSP) continually since the program's inception in the 1950s. SSP developed the first sea-based, underwater-launched Strategic Weapon System (SWS), a defense system that is truly critical to our national security. For more than six decades, SSP has maintained and upgraded this weapon system and we have been there every step of the way. The sea-based SWS is the ultimate stealthy weapon system and is the first leg of the U.S. nuclear triad. With over 70% of our nation's nuclear arsenal its importance to maintaining world peace cannot be overstated. The development of Columbia, the most advanced nuclear-powered, nuclear-armed submarine ever designed, as well the next D5LE2 weapon system is under way and will begin to be rolled out over the next decade. The Navy projects this system to be operational through 2084, meaning the program will have a total life span of more than 120 years. This is a unique program and BAE Systems employees on this program understand they are part of an important legacy.
As a decades long sole source partner on multiple contracts on behalf of our customer, our program has remarkable stability and is concurrently experiencing significant growth. Combined, these factors provide ample opportunity for professional growth and development for capable and talented individuals on our team.
