Vectoring "unique at the time"
"The engines were unique at that time in that they could be vectored by seven degrees in flight for guidance." Unlikely, as the S3D from which it was derived featured gimbaling and flew almost ten years earlier. Single-axis gimbaled engines flew in 1948 and two axis gimbals in 1949 per https://space.stackexchange.com/questions/5689/what-was-the-first-rocket-to-use-gimbaled-thrust/10426#10426
