Superbird-B1, sometimes identified as Superbird-1B, was a geostationary communications satellite designed and manufactured by Ford Aerospace on the SSL 1300 satellite bus. It was originally ordered by Space Communications Corporation (SCC), which later merged into the SKY Perfect JSAT Group. It had a mixed Ku-band, Ka-band and X-band payload and was rushed into launch at the 162° East longitude due to the launch failure of Superbird-B.
