RAF and Single Engined Fighters
The Gripen thread got me thinking as to why in the last 30 years the RAF (or MoD for that matter) have not chosen any single engined interceptor/attack aircraft and have kept with the two engine design.
Bucanneer
Phantom
Lightning
Tornado
Typhoon
Sea Vixen
Etc
Alright we have a few examples such as Vampire, Venom, Hunter and Harrier (and the F-35) but the trend seems to be put towards the two engine layout.
Why is this? Has this been a decision maker in future programmes also as to why we haven't gone for Gripen or the F-16?
