Small world. Just signed a contract with a bubblehead. First I've met. SSBM Wyoming (ret)
I was on the Wyoming! I wonder if it's someone I know...
By the way, it's SSBN
SS - submersible ship
SSN - submersible ship nuclear powered - fast attack submarines
SSBN - submersible ship ballistic missile nuclear powered - trident submarines
SS's are gone now... those were the old diesel boats. The modern navy is SSNs and SSBNs and a couple of SSGNs
And there's your crash course in submarine designations.
