They are, in fact, the Kushan target drones fom the training missions in Homeworld 1.
The plan is to make a set of the basic flyable units and a set of beginner missions ( cos I am a beginner when it comes to missions... but I learnt a few things just placing the units for that shot ). These are not just HW units pulled out and converted, but new meshes with more detail and a few of the things they would have put on the models had they been able to add more polygons. New textures are also going to feature, based on the originals but optimised for what the FS2 Open engine needs.
The plan is to make some missions around the training levels, and then around being part of the forces defending the planet when the attack happens. As a survivor of this, you would be taken aboard the 'Banana' as part of it's core defensive fighter screen. Flyable scouts, light interceptors, heavy Interceptros, bombers and defenders will make up an initial release as a 'dogfight' pack. Then will come the Mothership and capships with some proper HW based missions and a story line.
All models will be released with a proper set of LOD's and textures and in fully workable condition. I hope to avoid the trap of making eye-candy ships without the substance ( turrest, subsystems, lods etc)
