Got the bug to build a supersonic transport airliner.

I've looked around the forums, but haven't found anyone else who has put one together with GURPS Vehicles - or maybe someone has, but has not bothered posting the specs here. I'm thinking the following:

-STOL wings
-Superior or Excellent streamlining with a lifting body
-4 turbo-ramjet engines

Thoughts?

On the GURPSnet mailing list, Onoo Mayer has been doing VE2 'Vehicle of the Week' for ages, and apparently did a military SST at some point, but I couldn't find it. However, he kindly did up one that's basically the Concorde.

The Supersonic Transport (SST) was an optimistic design from an
optimistic time. Many orders were cancelled before it entered service,
reflecting high costs and operational challenges like the sonic boom.
The aircraft has a cockpit with seats for two pilots, one engineer,
and two extras. Next come the entry/galley area, the first part of the
passenger cabin, another galley area, the second part of the passenger
cabin, and finally another crew area with the aft luggage hold. There
are 108 passenger seats in a typical configuration.
The engines burn 11,160 gallons of jet fuel per hour at 1,210 mph. A
full load of fuel is $94,500.

Subassemblies: Body +7, ten Retractable Wheels +2, two Wings +5, two
Pods +3.
Powertrain: Four 31,000-lbs. afterburning turbojets; 3,000-kWs lead-acid
batteries.
Fuel: 31,500 gallons jet fuel (fire on 13).
Occ: 4 RCS, 6 folding NS, 108 NS (all with superior access).
Cargo: 600 cf.

Armor F RL B T U
All: 3/8 3/8 3/8 3/8 3/8

Equipment:
Body: Two very-long-range radios; 20-mile air search radar, no
targeting; two flight recorders; two sets of precision navigation
instruments; two transponders; three inertial navigation systems; two
autopilots; two full fire suppression systems; six small galleys; three
roomy toilets with superior access; 154x6 man-hour limited life system.

Statistics
Size: 202'x84'x40' Payload: 231,350 lbs. Lwt.: 409,120 lbs.
Volume: 19,159.4 cf Maint.: 32 man-hours Price: $45,481,175

HT: 11. HPs: 12,000 Body, 300 each Wheel, 5,400 each Wing, 750 each
Pod.

gSpeed: 265 gAccel: 15 gDecel: 10 gMR: 0.25 gSR: 5
Ground Pressure Extremely High. No Off-Road Speed.

aSpeed: 1,855 aAccel: 9 aDecel: 22 aMR: 5.5 aSR: 6
Stall Speed 170. Ceiling 19,100 yards (aerodynamic limit).

Design Notes
The nominal performance assumes sustained use of the afterburner. It
was intended for periods of climb and acceleration only, reducing top
speed to 1,515 mph. The statistics are calculated with 3,000 lbs. of
cargo in addition to cabin luggage.
Body is 13,932 cf, with excellent streamlining. Wheels are 696.6 cf,
retract into Body. Wings are 2,400 cf each. Pods are 213.7 cf each.
Structure is heavy, standard. Armor is standard metal. Sealed.
Electronic controls with duplicate maneuver controls. 594.1 cf of empty
space in the Body and 263 cf in each Wing. Empty weight is 177,770 lbs.
The vehicle uses the design rules from Vehicles [second edition, third
printing, July 2010 errata], VXi, and VXii (including the armor volume,
stall speed, and ceiling rules) with the text format from Vehicles Lite.

THANK YOU! This seems to be a good starting point to plug in the numbers from.
