Are there any SAMs small enough to fit into a Torpedo casing?

Something like an electric torpedo with a fake extendable periscope
and a SAM, and the sensors to direct it, could swim a few miles
from the launching sub, then expose the fake periscope
periodically.

Then when an enemy aircraft comes into range... *whoosh!*

Maybe the torp/decoy could be equipped to replicate the
acoustic and magnetic signatures of a sub too.
