The munition would need a different, suitable message receiver and decryption."<br />The communication is the difficult part. You could sink containers to the bottom of the sea and link them with fibre optics to a command center. But I have no idea how to conduct a suitable underwater communication of fast moving small objects over long distances. Long wavelengths get absorbed after a short distance under water and suitable short wavelengths would be X-ray. The communication is best conducted over shortest distance under water, requiring air or space assets for coordination. Is this still a torpedo or a robotic kamikaze submarine?Anonymousnoreply@blogger.com
