Looks awesome! When first I saw it I assumed its based on the Homeworld Universe? .. ah just noticed all the other Homeworld comments below Anyway - AWESOME! Will we ever be blessed with Homeworld 3 I wonder.
"Well armoured"... except for that window on the front! Even supposing it's made of deposited-film diamond allotrope sandwiched between transparent aluminum mylar layers with nano-scale reactive gold spiral structures suspended in aero-gel inserts... it's still gotta be a "softer" target than the actual armour. And it's high albedo with arrows pointing right at it! It's like you're trying to get the pilot killed! A better name would be the "Uriah"
But seriously, I love it. It just annoys me to see windows on armoured vehicles... it's such a weakpoint... that's why real armoured vehicles don't have windows, but rely on sensors and tiny well-armored slits for use with the Mk1 eyeball (which is already useless on the modern armored battlefield, even more useless in aerial combat, and would be absolutely useless in any kind of space combat).
What kind of engines and armament does it carry? And how does it develop lift? The design is clearly streamlined, and there are wings all over it... and that says 'atmospheric'... but the wings are all stabilizers and control surfaces (which once again, only serve a purpose in atmosphere)... and it's not a lifting body design. It almost looks like it could have exo-atmospheric capabilities... except it isn't large enough to carry the reaction mass necessary to break orbit and then do any kind of useful maneuvering and then do a powered de-orbit (even assuming fusion engines and dual atmospheric gas/internal stores reaction systems). Also, there are no obvious RCS thrusters... not that RCS have to be obvious or anything. All of which makes me think it's a pure air-breathing atmospheric fighter. But if it is a spacecraft... where's all the reaction mass go??? Even if it's 'just' leaving a carrier or base, maneuvering, and returning home it'd require a lot of mass to 'delta' its considerable 'v'.
Of course, if it's got a He3 fusion reactor, and is using the waste heat to crack H atoms into protons and electrons, then accelerating those particles via extremely efficient dual ion drives... it could carry enough reactant to get up to a respectable speed, do some combat maneuvers, and RTB without "refueling" (really re-reactant massing). But I'd expect that the base or carrier would need to have some system to 'catch' craft that had used too much reactant and could not maneuver into a "landing' configuration (whatever that might be).
But it's wildly possible I'm over thinking this! So: Cool design, it's cute!
Dude... I do 3d scifi models and if I had more images and the specs for this I'd totally make a model of it (Ever feel like doing a set of orthographic projections?). Know what you mean by sketching though. I've come up with some nice design's just by screwing around and taking a bit of this and a bit of that, and throwing them together. Very nice and I have to admire the sheer artistry shown here.
