The BBC are currently showing a six part documentary based aboard HMS
Queen Elizabeth during the CSG21 deployment - which included the embarkation of USMC jets as well as the RN/RAF ones. Like all naval documentaries it has included things such as people working in the galley, the watchkeepers on the bridge, firefighting and first aid training, close range gunnery, and sailors having to deal with gash.
Like many documentaries I have seen about US Navy carriers, it has included aircraft launches and recoveries, the aircraft being marshalled on deck, and replenishment at sea - the nuclear powered carriers still need supplying with aviation fuel, weapons, and provisions.
The second episode was shown on BBC2 on Sunday 29 January, and featured things such as F-35B Lightnings being launched on missions against terrorists in Syria and into the Black Sea, jets being launched in response to approaching Russian aircraft under the control of one of the destroyers, and Merlins being launched for surface search and for ASW - presumably cued by one of the frigates. The talk (by the Strike Group staff types) was of 'protecting the force', as opposed to the over simplified 'protecting the carrier'.
The fourth episode (Sunday 12 February) featured ASW.
The detection of a possible submarine by HMS
Richmond and the use of sonobuoys by the Merlin reminds me of comment by a former USN aviator that a surface warship going active on sonar (particularly LFAS) gives the game away to the submarine looking for the task group. Whilst going active with your towed array allows you to cue the ASW helicopter with dipping sonar, passive detection means a larger search area, so dipping sonar is less useful.
