In the past couple of days, several sources have reported on the fact that in 1986, the US President, Ronald Reagan, offered Britain the opportunity to co-operate on stealth technology and purchase the Lockheed F-117 Nighthawk. Details of the project, codenamed MOONFLOWER, have become known through the recent release of files by the British National Archives. This release is part of the material coming out of the Prime Minister’s files for the 1980s and the specific reference for MOONFLOWER is PREM 19/1844. An important issue to note with these files is that they have not been digitised and were opened just before the New Year. This is an important consideration when reading many of the reports on the internet as it is probable that the one in The Guardian – from which most derive – has only cited certain parts of the file. Indeed, I have not read the file yet.
The F-117 remains one of the most iconic aircraft of the latter part of the Cold War. Announced in 1988, the F-117 emerged from Lockheed’s Have Blue project and was developed by the company’s Skunk Works division. The F-117 was first operationally used in the US invasion of Panama in 1989, but it was during Operation DESERT STORM that it rose to prominence. During the 1990s and 2000s, the F-117 was used in other conflicts, and one was shot down in 1999 during Operation ALLIED FORCE, and it was eventually retired in 2008.
What appears to have got people talking is the fact that Britain was offered the F-117 at a time when it was still officially a ‘black’ project i.e. before it existence was officially acknowledged. Moreover, according to the various reports, the key reason that Britain did not pursue purchasing the F-117 was for this very reason. However, while this may be one reason for rejecting the F-117, it should be noted that while the release of British files is interesting, this is not strictly a new story, though it is potentially a new dimension. Several histories of the F-117 cite the fact that in 1986, several Royal Air Force (RAF) test pilots were sent to fly the aircraft. For example, Paul Crickmore reflected that the RAF ‘had its chance to evaluate the F-117’ as a thank you for British support of Operation EL DORADO CANYON. However, what these secondary sources lack is the archival evidence to understand why the evaluation took place. It is probably – though I would not like to say for certain until I see the file – that this assessment formed part of this project.
As already noted, the reason cited in the reports for the RAF not purchasing the F-117 was the ‘black’ character of the project; however, I have to wonder how well this aircraft would have fitted into the Service’s force structure and concept of operations in the 1980s. Moreover, it will be interesting to see if anything more is mentioned in the file as to why the F-117 was not purchased. Nevertheless, a few issues come to mind that may have been challenges. First, the RAF operated at low-level in small packages, and I am unclear how the F-117 would have fitted into this concept of operations. Second, by 1986, the RAF was in the middle of purchasing the Panavia Tornado that had been designed for the low-level role, as such; again, what additional capability the purchase of the F-117 would have added to the RAF at this point remains unclear. Finally, there is the issue of numbers. The F-117 was never built in significant numbers, and it seems unlikely that the RAF would have bought more than the United States Air Force, as such, again, what additional capability would the addition of a highly complex piece of equipment have added to the RAF? Yes, it would have added a stealth capability but this needs to match a concept of operations, and in my mind, this remains a murky area. As such, this is more an interesting example of the so-called ‘special relationship’ rather than a significant ‘What-If’ for the RAF.
This is not, however, where the story ends as in 1995, Lockheed once again tried to sell the RAF an improved F-117 that included locally produced content, such as GEC-Marconi supplied avionics. This approach was in response to the RAF’s Staff Target (Air) 425 that began the process of looking at replacing the GR4 variant of the Tornado, which became known as the Future Offensive Air System (FOAS). FOAS closed down in 2005 and was rolled into Future Joint Combat Aircraft project that has seen the purchase of the Lockheed Martin F-35 Lightning II – an aircraft with a stealth capability.
