A modified and upgraded sucessor to the Space Shuttle, the Pathfinder was designed in an alternate reality where the Soviet Union won the space race. In response to this defeat, the United States developed an advanced spacecraft to compete with the Soviet threat.

The Pathfinder features a powerful nuclear engine with an estimated ISP of 2600. This craft carried enough liquid hydrogen to get to the Moon and back. It’s jet engines allow this vessel to get to 12km or more. Its vacuum engines provide even more efficient thrust at the expense of TWR.

Missile launch sequence:
- open ag4 “cargo bay”
- activate ag5 “missiles”
- set slider 1 to 100%
- activate ag6 “launch missiles”

Flight profile:
- take C-5 to 10km
- detach Pathfinder at 10km and activate jets
- climb to 12km
- activate main nuclear engine
- pitch to 45 degrees
- at 30km, activate vacuum engines
- at 40km, gradually pitch down until you get to 60km
- at 3,200m/s, deactivate main engines

    @lordvader0219 ok, but I want you to make a engine with xml edit that makes it so that it’s actual in-game shown Isp is 2,600.

    @EffIcentRocketEngineering I used a regular nuclear hydrogen engine. The way I made the craft have an ISP of 2,600 was by adding massless tinkered hydrogen tanks next to the regular liquid hydrogen tanks to give the craft more delta v.

    Ok, now make the 2,600 isp engine and post it

    Wonderful. It has been really fun to play with. I cheated a little, and stuck a couple of rocket booster to the side of the C-5 to get a little higher before launching the Pathfinder.

    @ZenEvil there is a gyroscope in the cockpit under the seats. If you need more power, you could increase its size and reduce its mass with the tinker panel.

    This rocket is great but u need to add the gyroscope

    Just saying you need to fix the weight disruption because after landing it had too much weight at the back but other then that great build

    Finally. We have all crafts from "For All Mankind", not counting the expansion of Jamestown
