The Yellow Fleet was the name given to a group of fifteen ships trapped in the Suez Canal (in the Great Bitter Lake section) from 1967 to 1975 as a result of the Six-Day War. Both sides of the canal had been blocked by ships scuttled by the Egyptians. The name Yellow Fleet derived from their yellow appearance as they were increasingly covered in a desert sand swept on board. After eight years, the only ships that were able to leave under their own power were the German ships Münsterland and Nordwind.

In June 1967 the fifteen ships were sailing northwards through the Suez Canal as a war broke out between Israel and Egypt in what was to become known as the Six-Day War. Both ends of the canal were closed, and after three days it became apparent that the canal would remain blocked for some time as a result of the scuttling of ships to block its passage. Fourteen ships were forced to anchor in the widest part of the Suez Canal, the Great Bitter Lake. Some of the scuttled ships cut off the SS Observer from the other ships and it had to anchor in Lake Timsah.
