U.S. Representative Ed Case, Hawaii's First Congressional District, greets Sailors aboard the Virginia-class fast-attack submarine USS North Carolina (SSN 777) before touring the boat off the coast of Pearl Harbor, Hawaii, Jan. 15, 2023. USS North Carolina is the fourth submarine of the Virginia-class; the first class designated and built post-Cold War in order to meet the challenges of the 21st century, and has improved stealth; sophisticated surveillance capabilities, and special warfare enhancements that enable it to meet the Navy's multi-mission requirements.
