Are you talking about the use of Twitter? Yes I have my doubts too, but remember it does reach people, and the average person has a shorter attention span that the average Goldfish. A fuller explanation would be that the intercept was controlled by HMS Defender - in other words the destroyer is actively involved in carrier based air defence. Likewise HMS Kent could track a submarine but to localise and prosecute you need helicopters with dipping sonar.
As for 'silent service' - well that worked well in the past....... Apart from making the RN more vulnerable to cuts and political interference, that is. A poorly articulated case for new carriers in the sixties, based on an out of area role instead of NATO (it was the need for ASW and supporting air defence in the Atlantic that led to the Invincible class/Sea Harrier/ASW and AEW Sea Kings), then not being willing to flag up the role of the Sea Harrier throughout the nineties and beyond, and then being at risk of deeper cuts and suffering political interference due to the reasons for a number of things being the way they were not being adequately articulated, that is.
