The 'Cold War' was not just something that affected the US. All of the NATO countries were involved in it in some way. And being on any ops during that period was stressfull for all involved.

The USN and RN ran regular probes into Russian water using their submarines. The Norwegians did a lot of obs on Russai too.

Most of the NATO airforces where either chasing Russian aircraft out of NATO countries airspace or doing their own covert overlooks on Russian ports and military instalations.

In 1979 Admiral Sir John Fieldhouse, who was skipper on HMSm Dreadnought (the first nuclear powere boat in the RN) visited a submarine I was serving on and said that he thought that the next big conflict would not be started by Soviet Russia but would start in the Middle East. How true he was.
