This is something I've been working on in the background for a while. It's an attempt to see how a large hangar bay might work and at the same time produce mainhalls using modular components.
It's nowhere near as advanced as mjn.mixael's Galatea mainhall project.
One of the ideas I came up with was a universal fighter tray capable of reconfiguring to accept most of the FS fighters and the Athena light bomber.

Another one was about storage, using a rack method developed for cars. This rack can hold twenty two fighters. Another possibility is to have the trays move instead.

My starting assumption on the racks is that the Bastion mainhall is for fighter launch and recovery with sixteen trays equal to four wings. The rest of the hangar is devoted to other tasks. Placement is subject to change though. Further to the rear we have elevators for the heavies like the Ursa etc. Other areas are assigned to support ships, bombers and weapons. Excuse the mess.

The aim hopefully, is to develop a few mainhalls with this messy Bastion wip being another one.

At a later stage it should be possible to walk around the hangar bay, either in a mini game or in a browser using Unity.
