Reminds me of the first firing by HMS Splendid in '98. I was in the crewroom at work and everyone gave a little cheer when the news footage showed it blowing up a building.
Until the reporter said it had hit a replicated communications center, then everyone went stoney-silent - comms was our bread and butter.
Good luck Astute, pack up your troubles in your old kit bag and smile, smile, smile.
