USS YF-448 was an American YF-257-class covered lighter built in 1943 for service in World War II.

White Pine was unique in her class for having "spuds," that enabled her to service navigational aids in areas other tenders would find difficult or hazardous.

YF-448 was delivered to the supply officer at the Brooklyn Navy Yard, New York, on 20 June 1944, and commissioned on 11 July 1944, with a single mast and boom hoist.

Before commissioning, White Pine was outfitted with a barge pusher on the bow to adapt her for working aids to navigation on the western rivers.

In addition to servicing aids to navigation, she patrolled the Mississippi River for the Marathon Race in 1960.

In 1965, White Pine assisted with firefighting on the Columbian M/V Ciudad de Nieva near Baltimore, Maryland.
