About this launch
In November 1995, Hughes was awarded the contract for Thor 2, a high-powered version of Hughes' spin-stabilized HS-376 model. Thor 2 was successfully launched in May 1997. That same month, Telenor announced the award of a follow-on contract to Hughes for a second high-powered HS-376HP satellite, Thor 3, which was successfully launched in June 1998.
