The Aviary class has 12 hangars each equipped to contain several shuttles or a large Raven/Vulture/Eagle class starship.
The lower part has docking sections for a Bat class Escort vessel, and the aft part has docking for a Mjolnir class Starship.
The mid-size warp engine and coils of the Aviary class take it up to a sedate warp 3, and are only there because at 750m long and 750m wide, this ship is too big for impulse. This doesn’t really affect the performance in practice because the Aviary class is usually primarily driven around by a Mjolnir Class.
