My friends and I did some math on #ForAllMankind's Pathfinder shuttle and came to the conclusion that, to be able to reach orbit from an airlaunch, have the propellant fit inside its hull, and be light enough for a C-5 Galaxy to lift it, it needs to have a Liquid Core NTR.
From an airplane launch, let us assume you need around 8.8 km/s of ΔV.
A NERVA engine has an Exhaust Velocity of about 8.25 km/s.

Using Tsiolkovsky's rearranged to find the mass ratio, we get that:
e^(8.8/8.25) ≈ 2.9

1/?
Let us assume Pathfinder weights more-or-less the same as the Shuttle Orbiter, and has a payload capacity of ~80 Tons. It thus has 80 + 20 tons = 100 Tons at launch, sans propellant.

A mass ratio of 2.9 makes it so it has a wet mass of 290 tons.
