Is the MOSS a real thing?

This type of decoy wasn't in Dangerous Waters at all and we are talking about older tech in Cold Waters than dangerous waters. I'm having some great fun with this type of decoy.

Short answer is yes. Believe it was mainly meant to be used on boomers though and was retired in the late 90s (pretty sure the thinking was that it wouldn't be effective against the newer Russian torps).
