A Hanger here removes the main functionality of why this vessel was built and is in service!
Not really. Most landing of equipment is done through the dock. The main impact of the TAS on amphibious ops is to reduce deck space for containers, vehicles and the usual random deck cargo. The cranes actually have a 360° arc rather than the 180° that you mention.
Bear in mind that the TAS was fitted to Largs in order to allow her to embark a Lynx whilst engaged on APT(N) where amphibious capabilities are a secondary consideration to counter-narcotics.
Secondly (and this is really clear in this pic- bless the person who took it), see the external access stairs.
The key abandon ship points on a Bay are 1) the boat deck, where the lifeboats and davit-launched liferafts (the two primary means of evacuation at the lower end of the embarked personnel scale) are located and 2) the MES, which is behind the double doors just ahead of where the accommodation ladder is, on the deck below the flight deck.
I’m not sure where you’ve got the idea that the superstructure is small. There are two full height internal stairs, port and starboard, at the forward end of the superstructure.
Neither of which really matters since the TAS doesn’t affect use of the external stairs.
