I’m not sure where this fits in the proposed scoring system, but here’s my entry for category 3:

Lifter 2a

Payload Mass: 11.6t

Lifter Total Mass at Takeoff: 32.22t

Lifter Mass Empty: 11.82t

Liquid Fuel: 1500

Oxidizer: 660

Fuel Cost: 1318.8

Cost per Ton: 113.7

Powered by 2 RAPIERs and 1 NERV. Just enough Oxidizer to push through the 30-40km, where the NERV can take its time getting to orbit.

Great Entry

That's so economic! Looks great. I thought it'd be better to have as less engines as possible, due to their mass. Now this one teaches me a lesson!

Also, I couldn't expect Nerv for LKO Lifter. Thanks!

 

Besides, I'm going to start the new challenge, with the entries given here included. Please take a look on it.

Thought I'd test the limits of that ship...

 

7425LF plus 4552.57O equals a fuel bill of 6760. Lifting 62 tons for a score of 109.

In Category III, I noticed that @NightshineRecorralis had room for a third ore tank in his cargo bay, so I copied his plane from his pictures, and flew it with
  10.5 tonnes payload  /  ( 34460 cost  - 33341 recovery)  = 107 funds/tonne
Maybe I used a bit more wing incidence, and followed prograde all the way up, rolling inverted to slow the climb for the speed-run.  Somebody should break 100/t soon.

A try at a Mk2 RAPIER/Nuke hybrid; works well, but not cheap enough.

 

I reckon I can get that down to the required efficiency with a touch more tweaking (perhaps just extend the bay a bit; it can take a lot more weight, I'm running out of space).

But, for now, √157/ton.
