Briefly: Spanish police find 'drugs' sub:
A submarine which police say may have been used for cocaine smuggling has been found floating off Spain's north-western coast...
While submarines are not known to have been used for drug trafficking in Spain, they have been used for this purpose in Colombia.
Reminds me of the online demo (and game) of the Swedish stealth ship where a useful scenario for stealth is littoral defense (vs penetration).
We are VERY likely to see more of these headlines in the near future.
