NATO 6S Vertical Launch Missile? Cancelled before mid 1982. BAe Prime Contractor?

[TinWing]

There's an interesting referendence in the May 1982 International Defense Review, p626: "British Aerospace, which was the prime contractor for the now cancelled NATO 6S vertically launched missile ..." The context is the first public showing of vertical launch Seawolf and the suggestion that VL Seawolf "could form the basis of an international project to replace NATO 6S?"
