The second stage buoy needs sensors (be sure to check no engine) for which I use active because that guarantees detection range reliably above a given hull size e.g. R10 = 500t typically >1m km depending on sensor tech.
The separation range for the buoy determines the distance to target at which the payload missile launches, the expected AS detection range needs to be at least equal, or more to counter ECM.
Bear in mind the target could flee so the missile flight range needs to be more than the separation range by approx missile max flight time times target speed.
I use minelayers which "launch as ready ordnance" static buoys, with active sensors and second stage payload. The payload is targeted by the buoy sensor so the missile does not need sensors unless there is a risk of the target being destroyed before the missile reaches it and you want it to redirect itself. Typically a minefield launches in one go and so the missiles all hit simultaneously and there is no intervening turn in which the missile can redirect.
