short range torpedo

Mostly uploaded to transfer between computers. As no-frills as it gets. Active sonar with direct tracking (no target leading). Very small, though, and the range isn't terrible.

Far more advanced APN torpedo based on the missile tech in the works. Trying to keep it small too, but it's an uphill battle. Definitely working out to be bigger than this one by some margin.
Edit: APN torpedo now available here:
