I agree that it doesn’t look like the best way to launch.In the event of a missile emergency in port (or on the surface), all sub launched missiles had a procedure to eject the missile from the tube towards something less expensive to destroy. The idea was to list (angle) the boat and use the steam generator to pressurize the tube and eject the missile from the tube. The rocket motor wouldn't ignite, but the missile would go far enough away that the chemical explosion of the rocket (hopefully) wouldn't destroy the sub or damage the warheads enough for the release of radioactive materials.
This looks like they used that same procedure for a surface launch. As long as the missile is out of the tube when the rocket motors are ignited, the sub would be, relatively safe.
I can see from that pic why they chose not to use that form of launch ever since the deployment of sub-launched ICBMs.
However I have heard a Trident D5 can hit Russia even if in port. Obviously the facility the Trident sub was at would be a target and it would take a while for a sub to get underway.
That led to my comment about launching while in port.
