Help me design a missile for screening approaching bombers.

Bombers and Strike fighters obviously have a problem: if you send them to attack a ship with good AA, they're going to be shot down. However, what if the AA was busy with something else?

My idea for solving this problem is a missile that can go immediately ahead of strike groups and force target ships to shoot them down or receive high damage.

To my mind, the necessary characteristics are:

• high damage so the missile cannot be easily ignored
• enough resilience to Soft-Kill defenses that the target ship cannot use them against this missiles without meaningfully decreasign its ability to deal with the following strike group
• either enough survivability or sufficient numbers for a salvo to give the strike group a meaningful window of relative safety.
• small enough cost that it is justifiable using the missiles to scrren for the craft rather than the opposite.

As a complete layman, my first design for this is a torpedo with a drive that prioritizes a range of 14.000 and tries to balance speed and manouverability so it goes about as fast as the craft it is meant to screen; for the same reason it has Cruise Guidance. Payload is HE to reduce cost, and the tracking system uses Radar (not extended or steerable in order to grant better contorl over which target it goes for) for targeting and Anti-Rad for validation, programmed with ACCEPT so the missile can go for any signature but will prefer those that emit a jamming signal.
