Motto:

RFA Diligence (A132) is a fleet repair ship of the Royal Fleet Auxiliary. Diligence first served the RFA during the Falklands War as a civilian owned ship taken up from the trade. As MV Stena Inspector, the ship repaired many British vessels. Stena Inspector was purchased by the Government in 1983 and renamed Diligence.

Diligence has provided damage repair work many times during its lifetime. At the end of the Iran-Iraq War, the Straits of Hormuz were mined, and Diligence supported the multinational minesweeping operation to clear that vital chokepoint. Diligence also helped to repair HMS Southampton after collision damage. The ship returned to the Gulf in 1991 to support operations during the Gulf War by repairing American ships damaged by mines.

During Operation Ocean Wave 97, Diligence deployed to the Far East as a submarine support ship. The following year, the ship supported 3rd Minecounter Measures Squadron in the Persian Gulf. Following just two weeks in the UK, Diligence departed for the south Atlantic, returning to Faslane in December 1998. Early 1999 saw the ship again deployed to the Falklands region.

2001 saw a large exercise in Oman, and Diligence supported the four MCMVs involved. The ship's next wartime assignment came with the large taskforce deployed against Iraq in 2003. Returning to familiar territory, Diligence supported the largest British fleet deployed since the Falklands War.
