USS AFDM-3, (former YFD-6), was the lead ship of the AFDM-3-class floating dry dock built in 1943 and operated by the United States Navy.

[3] In late December 1944, USS Arikara (AT-98) voyaged to Trinidad where she took YFD-6 in tow before continuing on to the Panama Canal.

YFD-6's center section fully turned 90 degrees, floating on its side with the support of a thousand Navy pontoons installed atop the wing wall.

This work, done by Navy SeaBees, was necessary to allow the drydock section to fit through the canal's locks.

[11] In 2010, the Bender Shipbuilding Company was declared bankrupt thus all systems were acquired by the Signal International.
