SS Denebola (T-AKR 289) is an Algol-class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force (RRF).

She was built as a high speed container ship by Rotterdamsche D.D.Mij N.V. in Rotterdam, Netherlands, hull no.

[1][2] Due to her high operating cost, she was sold to the United States Navy in October 1981 as USNS Denebola (T-AK-289).

[6] In 1994, Denebola, along with USNS Capella (T-AKR-293), worked with NATO forces on convoy exercises in the Mediterranean.

If activated, Denebola will report to the Military Sealift Command Atlantic Fleet and change her prefix designation from SS to USNS.
