The National Archives [USA] are asking for volunteers to transcribe thousands of pages of declassified CIA documents. To assist, you have to log in to the National Archives Catalog. The endeavour is part of Sunshine Week which is an open-government initiative, started by a group of newspaper editors, to educate people about the importance of government transparency and the dangers of excessive state secrecy.
You can browse some of the raw documents here.

It is likely to be exactly or less than 18 letters long, they can black out more than is necessary to throw people off trying to do what we're doing. ('context analysis'?)
It's also a possibility that the word is longer than the blacked text and it's been whited out or photo shopped.
The GIMP has a grid tool that is excellent for trying to determine the length of the blacked out text.
