USCGC Smilax (WAGL/WLIC-315) is a 100-foot (30 m) United States Coast Guard Cosmos-class inland construction tender.

[1][2] After commissioning, Smilax was assigned to the Seventh District and was stationed at Fort Pierce, Florida where she engaged in the aids to navigation mission.

On 9 November 1965, she moved to Brunswick, Georgia as her new homeport, carrying out the aids to navigation mission for that area.

[4] In July 1999, Smilax moved to her current homeport of Atlantic Beach, North Carolina, relieving her sister ship USCGC Primrose (WLIC-316) of her aids to navigation duties.

From her current homeport she is responsible for maintaining 1,226 fixed aids to navigation such as lights and range markers.
