Victory was permanently dry-docked in 1922, as her timbers had deteriorated so much due to long neglect that she could no longer remain afloat. A series of steel cradles was installed to support her hull, but they proved to be a mixed blessing. The ship began to "hog" above the cradles, and sag between them. A better solution was needed, and has now been installed. It's quite a story, particularly for those who enjoy military maritime history, and those interested in complex engineering problems. Here's a Royal Navy video describing the project.
Looks like a good job well done. I hope Victory endures for many more years. If you ever get the chance, a visit to her, and to the other ships and establishments making up the National Museum of the Royal Navy, is well worth your time.
