This dates back to when I was first tinkering with the idea of a "Superfighter".

I actually lost the original 3-view sketch of this design, so I resorted to creating this schematic without a backdrop sketch to trace over (!) --- the first time I have EVER done so.
Compared to the original (as best I can remember it), this version is one hell of a lot more geometrically complex (if you can imagine that!), and has different thrust nozzles. I think I might have also neglected to add spoilers to the original.

As for the airframe itself, many of it's features --- as well as it's underlying concept --- are VERY different from any existing warplane.
The Lurker sits high off the ground atop it's landing gear, it has dual nose wheels, it's stabilizers are steeply swept-back and it's profile EXTREMELY slim, it has two different guns of two different bores, and it's airscroops are set overhead and are covered with a tightly-knit grating (the only REAL aircraft I know of with this feature is the now-retired F-117 Nighthawk Striker).

The concept is pretty unique as well; the Lurker is intended to whittle-away at enemy airpower through Fabian tactics, accomplished primarily through surprise, via stealth technology.
That may sound like the F-22 Raptor's mission at first, until you consider that the Raptor is designed specifically for Offensive warfare --- the Lurker is more of an "Aerial Guerrilla Warfare" platform, since it's intended to steadily wear the enemy down, rather than smash into them in force all the time.
In short, the Lurker's Stealth is the basis of it's concept of operations, not just extraneous "Bells and Whistles" like the Stealth features of the Raptor.

Stealth aside, the Lurker is by no means the "ultimate" fighter; it has awkward and HIGHLY unstable aerodynamics, lukewarm performance, finicky handling, and sub-par maneuverability.
It's also possible to load the Lurker with more than 68000lbs of fuel, ammo, ordnance, etc. --- but due to it's poor lift, it's maximum takeoff weight is only about 50000lbs!
The Lurker is also completely devoid of ANY curved surfaces whatsoever --- all exterior sides are entirely flat, and this is what gives rise to it's lackluster performance.
Only a highly-trained pilot would be able to control such a chaotic machine.
The Lurker also lacks Plasma Ejectors, so it relies on a lot more on RAM and it's radio-disruptive shape to conceal itself; that's why it's so jagged.


That's just to show that I'm not all about designing "pie in the sky", but the Lurker has some special advantages as well.

First are the guns. Having two guns of two different bores allows one to selectively engage foes with the appropriate rounds.
For example, given that aircraft are rather delicate, the Machinegun (that's right, a MACHINE GUN in a modern aircraft --- it's NOT a cannon!) is better suited to destroying them. It's would also be highly efficient for engaging ships and light armor, and for strafing soft targets like troops.
Most tougher targets, however, like tanks, bunkers, armored warships, attack helicopters, and stategic bombers won't take much damage from a smaller-bore autocannon (e.g., 20mm), and won't even FEEL a machine gun --- for those, you need a large-bore autocannon, and the Lurker has one.
For maximum punch, both can be fired in unison!

Second, with the ability to carry internal stores (in two large forward bays, and two small read ones) the Lurker can maintain a low RCS. It's not quite fast enough for supersonic cruise, though --- the poor aerodynamics see to that.

Third, it's high landing gear and grated overhead airscoops allow give the Lurker an extremely low propensity for FOD. That allows it to operate from rough or cluttered runways that a "hoovering" F-15 Eagle, for example, would never use.

Fourth, the canopy is made of flat-panel, inch-thick polycast --- 20mm shells can't punch through it, and bullets and shrapnel won't even scratch it. It DOES make the canopy difficult to remove manually in an emergency, though...

Fifth, it can also mount a booster engine for short-term flight at extreme speeds and/or altitudes. Foes expecting the same-ol' Lurker may be in for a nasty surprise!


Other features of the Lurker are more... strange, than anything else.

First, it has dual nose wheels. The obvious advantage is that if only one fails, you can still land on the other. The disadvantage is that they sap the Lurker of both space and weight.
Why TWO nose wheels? I don't really know --- I just felt like it.

Second, the controls are highly unusual compared to contemporary warplanes.
While the elevators, ailerons, and canards are controlled by a yoke/stick on the right side (like on most aircraft), the rudders and thrust -vectoring nozzles are controlled by ANOTHER stick/yoke on the LEFT side.
Buttons on the left stick also control the airhook, drag chute, and autopilot.
There are also two pedals, one in each footwell, that have two unique (and all-important) functions as well --- the left pedal controls the thrust of the engines (pedal to the metal = AFTERBURNER!), while the pedal on the right controls the airbrake (all-the-way-down = rudders and spoilers completely open as well).
A pilot used to flying aircraft with the control scheme used on regular aircraft would go CRAZY trying to keep the Lurker in the air!

Third, the aft wheels contain two small thrust-powered motors (one each), selectively fed by thrust from the engines while they idle --- this allows the Lurker to taxi without creating more than 5% thrust, and that makes them less dangerous for personnel, equipment, etc. in close proximity.
The wheel motors also completely obviate the need for a tractor to tug the aircraft around an airfield, as just 5% thrust is not strong enough to create hazardous jetblast.
The engines also have thrust-reversers, though these require a lot more than 5% thrust to operate effectively.


Needless to say, this is DEFINITELY an aircraft design that goes off the beaten path.
