As evey man and his dog has published today on the latest Australia-France submarine sign-off, squeezed in before the May 2019 Australian Election (remember that?) I'll comment on that tomorrow.
Meanwhile, above is a high standard submarine youtube, dated February 5, 2019, by Wendover Productions, on the following subjects:
0 – 4 minutes - mainly nuclear weapons implications of SSBNs
2:45 UK launch and other instructions to UK SSBN if Britain destroyed
3:05 UK SSBN may then do nothing or place itself under the command of US “or Australia”
4:28 subs have best food, why? “The chef has nowhere to hide if food is bad” :)
4:46 fresh food only lasts 2 weeks then goes downhill to canned
6:08 relatively huge (for a sub) US cafeteria seating. [The torpedo room is no longer the biggest crew hangout place]
6:13 gym equipment
6:23 bunks still cramped
6:40 personal comms from loved ones comes to personal email addesses on US subs. But messages still read first by a comms officer to 7:00 stop distressing family news [eg. Dear John letters]
7:20 VLF radio waves can be received underwater for instructions
7:45 VLF stations for US, UK and Australian subs include [lost at sea Australian Prime Minister] Harold E. Holt Naval (VLF) Communication Station in Western Australia
8:20 subs can actually transmit to satellite. [Though this is indiscrete, potentially interceptable by sophisticated Russian or Chinese opponents]
8:40 fully submerged navigation difficult. Active sonar indiscrete.
9:07 [Old fashioned] inertial navigation still used.
9:52 SSBNs are so stealthy that they may not sense each other - so collisions can occur – as happened in 2009 between a French and British SSBN
10:18 subs are dangerous , even in peacetime.
10:30 rescue subs
11:09 submarines are the best platform for anti-submarine warfare
