During this period, the Weapons Station was the Atlantic Fleet's loadout base for all nuclear ballistic missile submarines. Two SSBN "Boomer" squadrons and a submarine tender were homeported at the Weapons Station, while one SSN attack squadron, Submarine Squadron 4, and a submarine tender were homeported at the Naval Base. At the 1996 closure of the station's Polaris Missile Facility Atlantic (POMFLANT), over 2,500 nuclear warheads and their UGM-27 Polaris, UGM-73 Poseidon, and UGM-96 Trident I delivery missiles (SLBM) were stored and maintained, guarded by a U.S. Marine Corps security force company.

In 1997, the charity introduced a U.S. Libraries initiative with a goal of "ensuring that if you can get to a public library, you can reach the internet". Only 35% of the world's population has access to the Internet. The foundation has given grants, installed computers and software, and provided training and technical support in partnership with public libraries nationwide in an effort to increase access and knowledge. Helping provide access and training for these resources, this foundation helps move public libraries into the digital age.
