190223-N-PW480-237 NORFOLK (Feb. 23, 2019) The Nimitz-class aircraft carrier USS Abraham Lincoln (CVN 72) pulls into Naval Station Norfolk. Abraham Lincoln returns to homeport after completing a composite training unit exercise (COMPTUEX) with Carrier Strike Group (CSG) 12. The components of CSG 12 embody a team-of-teams concept, combining advanced surface, air and systems assets to create and sustain operational capability. This enables them to prepare for and conduct global operations, have effective and lasting command and control, and demonstrate dedication and commitment to becoming the strongest warfighting force for the Navy and the nation.
