The 18 UFO-related files only came to light last year, when the British Ministry of Defence (MoD) admitted they existed and had been withheld from a previous declassification exercise.
In 2013 the MoD claimed it had made public all of its formerly top-secret alien files, but following Freedom of Information Act requests, the existence of the remaining documents was revealed.
UFO disclosure campaigners have been fighting ever since for their release.
Express.co.uk has previously revealed the MoD had passed the files to the National Archive, which would decide the date of their release.
Now German news-blog on edge-science and the paranormal site Genzwissenschaft-Aktuell.de (Grewi), have revealed they will go public in August.
In reply to an enquiry by GreWi-editor Andreas Muller, a spokesperson of the National Archives‘ Information Management Department said: "I have been advised by our transfer team that they are currently in the process of finalising the listing for the records, which include the UFO files, and they are hopeful that the records will be transferred from the MoD to The National Archives within the next month.
