The answer is probably yes. From The Saker at unz.com:
To begin, let’s recap what just happened in the Crimean waters. First, the HMS Defender deliberately entered the Russian waters under the pretext that the Brits don’t recognize what they call the “annexation” of Crimea. The Brits deny it, but after seeing 4 bombs explode ahead of the HMS Defender, they altered their course as the Russians demanded.
Next, before looking into this deeper, let’s also keep in mind the following fact: the entire Black Sea is a de facto “Russian lake” meaning that Russia has the full military control of the Black Sea. For those alternatively gifted, let me explain what this means:
- The Bal and Bastion coastal defense missiles can sink any ship in the Black Sea in minutes.
- The Black Sea Fleet has seven advanced diesel-electric attack submarines, arguably the most advanced on the planet.
- The HMS Defender was operating without any air cover but detected over 20 Russian military aircraft overflying it.
For a more detailed discussion of this reality, please see these four (here, here, here and here) articles by Andrei Martyanov. For a more detailed discussion of the laws of the sea, please see this discussion by Nat South.
In other words, the HMS Defender was a sitting duck with no chance of survival had the Russians decided to fire in anger. General Konashenkov, who is in charge of contacts with the media, had this to say about the outcome of the British provocation: (emphasis added)
“The epic fiasco of the provocation of the British destroyer Defender in the Black Sea, which abruptly changed course from Russian territorial waters after the warning shots of the patrol ship, will remain a fragrant stain on the reputation of the Royal Navy for a long time”
(-: Thereby suggesting that the Brits soiled their pants and ran for their lives
Speaking of anger: I have been parsing the Russian media over the past couple of days and I will only say that there are A LOT of commentators who are mad at the Kremlin for NOT opening fire in earnest and sinking the Defender.
