The CF-16 proposal seems to have included the tangential Sparrow launch rails from the Vought Model 1600/1601/1602 naval proposal (presumably so that it could be better sold as an interceptor). Though, when in use they would block the now-standard setup of LANTIRN/Sniper pods and/or HARM Targeting System pod on the intake "cheek" stations. Of course these would not be needed in interception/air superiority role, but would be still interesting to know whether the Sparrow launchers were designed to be a fixed setup (thus limiting the CF-16's potential in the strike role) or if they could have been switched out as necessary.
