This pictorial journey will take the reader from the very beginning of the Skunk Works’ very first project (XP-80 Shooting Star) and follow the programme through prototype build-up, first flight and, if they reached the frontline, operational service. This treatment will be repeated for each of the 30 unclassified programmes designed and built by the Skunk Works. Each programme will form a chapter of at least two pages in length, with a maximum of 14 pages being allocated for programmes that went into production and merit more detailed coverage, such as the P-80/F-94/T-33 family, C-130 family and, of course, the A-12 and SR-71.
