The screenshot is from War in Heaven, Act 3 (Tenebra), Eyes in The Storm mission. Tenebra is in War in Heaven 2 campaign. The person playing there is flying an Uriel heavy fighter. You get to use it a few times in WiH. Plus, the screen is from an old version of Blue Planet. The current one is named Blue Planet Complete.
Blue Planet is a continuation of Freespace 2 story. If you are just getting started, I suggest getting FSPort and playing campaigns: Freespace: The Great War, Silent Threat Reborn, Freespace 2 Blue (a bit enhanced FS2 main campaign), then Age of Aquarius and War in Heaven - in that order. Blue Planet also refers to events from Freespace 1 and Silent Threat, so you may find it interesting.
The last campaign in BP is called The Blade Itself and it's a single mission "experiment" - the player gets to pilot a Karuna. I think that's interesting enough.
As for the cockpits, I believe that Lightning Marshal and Operation Savior make extensive use of them, they aren't as pretty looking as this one on the screen from BP. I don't really know much about cockpits in BP though.
