Finally, an update! After renaming the model, I did some reworking of the main engine, RCS pods, and added in the RCS nozzles. Took me forever because TS kept complaining about my boolean operations. I also broke up the model's body a bit and added the body flap at the back and part of the nose cap to the wing. It'll make texturing a bit easier.
Once I get all done I'll use TS' polygon reduction/normal mapping tool.

Like it ! It's what I would expect that the first future spacecombat crafts would look like. :) |

Glad you like it! It actually is a fictional combat spacecraft that is based upon the X-20 DynaSoar. Here's a link to the real-world X-20:http://en.wikipedia.org/wiki/X-20_Dynasoar. In my game world, the YF-19, a counter to the Soviet MiG 105 Spiral, picks up where the X-20 left off. It is a bit larger than the X-20 but advanced composite materials and aluminium-lithium alloys make it about as light. It has an International Low-Impact Docking System (ILIDS, prounounced "eyelids") port to dock with various spacecraft including the KH-10B spy station (another 3D project I'm working on for my game) and spacecraft from other countries. My fictional ILIDS is based upon the real-world Low-Impact Docking System (http://en.wikipedia.org/wiki/Low_Impact_Docking_System).
The YF-19 isn't a dedicated fighter: its pressurized payload bay can also hold small satellites, experiment racks, and passengers. Most of the time though, it holds a combat fuel tank and 6 space-rated AIM-120D Slammer missiles.
The Saber launches into orbit on top of a Titan 4 rocket. Once it completes its mission, the fighter de-orbits and glides to a landing like the Space Shuttle does. |

I must admit I saw Saber and I thought of the F-86 with the shiny fuselage but that's a cool successor. We've got people in UK who are sending civilian passengers up in a rocket soon. I'd rather fly in yours it looks good and solid, advanced ceramics. Ablation, the modern metal fatigue if you're the worrying type like me :)

I just did the back armor panels on the fighter. While the skin of the YF-19 is comprised of an advanced, lightweight ceramic/metal composite that is heat and impact resistant, it helps to have extra armor in vital areas. It's a little thin in the engine compartment, so the engineers added additional plates.
You can also see the four postholes where the YF-19 rests on posts built into the booster rocket interstage adapter. Explosive bolts fasten the fighter to the posts. When they fire, pneumatic pushers in the posts ignite as well, pushing the YF-19 away from the booster rocket's upper stage.

I figured how how to do the windows at last! I had to do an intersection with the body, then extrude upwards, then delete the underlying parts and extrude downwards to create window-like pillars that cut into the body slightly. After that, I just selected the body and did an object subtraction of the pillars. Here is the end result:
