About five-ten years ago wasn't Rolls-Royce working on a turbojet for a high supersonic/low hypersonic missile which I think was designated the YJ-102 (I don't know if I'm remembering correctly)?

Yes, for RATTLRS. It apparently had about the best thrust to weight ratio ever achieved and was similar in concept to the SR-71 J58. Program ended with successful test flights; unclear if anything was ever developed from the technology.

Yes, for RATTLRS.

That's the name I couldn't recall, thanks, I wonder if the test-flight results have been used since they were successful? If so I wouldn't be surprised if it was a black programme.
