Specs:

Max capacity: 5t to 300km orbit

Total thrust at launch: 3519.45 kN

Combined thrust of boosters: 2821.2 kN

  • Thrust of each booster: 1410.6 kN

Combined thrust of SSMEs: 698.25 kN (122% thrust)

  • Thrust of SSME: 232.75 kN (122% thrust)

Specific impulse of SSME: 374.1s

Orbiter mass: 21t fueled

Cost per launch: √111 305

Cost of shuttle: √46 592

Cost per kg to orbit (5t payload): √12.94

Shuttle can be flown unmanned.

How to fly:

Important tip: Tap F to lock heading.

1. SAS on, throttle at 20%

2. Hit Space to start SSMEs and then start throttling up 100%

3. Once the throttle is at 100%, you may hit Space again and the shuttle will lift off.

4. At T+ 10 seconds, roll 90 degrees (or to whatever the inclination of your target orbit is) so that the shuttle is pointing east.

5. After rolling, point nose at 85 degrees (from the horizon)

6. At 8km, pitchover to 70 degrees.

7. 60 degrees after 2nd SRB burnout

8. 50 d. after 350m/s (do not perform with heavy payloads, as the shuttle will pitchover by itself). If the shuttle is having trouble flying straight, you can fire the OMS (action group 9) for assistance. Just remember to deactivate it after the booster burnout.

9. Drop the boosters as soon as they burn out. At this point, the shuttle will start pitching up- try to correct it, but don't press the wrong buttons!

10. 30 degrees a few seconds after booster separation

11. 20 degrees past 40km

12. Throttle down a bit (try to stay above 2/3 throttle) and roll 180 degrees at 50km. Keep the nose at 15 degrees above the horizon.

13. Watch apoapsis and cut the throttle once at desired height (the shuttle may run out of fuel when lifting payloads before the apoapsis is high enough). Turn on fine controls for OMS flight.

14. Stage or press 9 to start the OMS.

15. Circularize the orbit.

Orbital Activities

- Press action group 1 to toggle the cargo bay doors.

- Press action group 2 to toggle docking port covers.

- Press 3 to release the payload

Returning to Kerbin

1. Using the OMS control point, burn retrograde to deorbit.

2. Press 1 and 2 to retract everything.

3. Try to keep the nose slightly above the horizon during re-entry, but try not to pitch up too much.

- The orbiter may flip if it has a lot of fuel in it, although flipping is usually caused by pitching up too fast and too much, which can be avoided.

4. After you drop below 12km, point the nose slightly below the horizon.

5. Deploy the landing gear when you get close to the ground.

6. Slowly lift the nose up and try not to lift it pass 20 degrees above the horizon.

7. Carefully land the shuttle (tailstrike hazard)

Tip: If the shuttle flips while flying, pitch up until it is aligned with prograde and then fire the OMS if there is still fuel. If you are too close to the ground or unable to recover from a spin, press 0 to deploy the emergency chute.

Combined thrust of boosters: 2821.2 kN

  • Thrust of each booster: 1410.6 kN

Combined thrust of SSMEs: 601.5 kN (105% thurst)

  • Thrust of SSME: 200.5 kN (105% thurst)

Specific impulse of SSME: 375s

Shuttle can be flown unmanned.

How to fly:

Important tip: Tap F to lock heading.

1. SAS on, Coarse control on, throttle at 20%

2. Hit Space to start SSMEs and then start throttling up 100%

3. Once the throttle is at 100%, you may hit Space again and the shuttle will lift off.

13. Watch apoapsis and cut the throttle once at desired height (the shuttle may run out of fuel when lifting payloads before the apoapsis is high enough). Turn on fine controls for OMS flight.

14. Hit space, press 4 to jettison the cargo bay cover, and select "control from here" on the small docking port under the shuttle. This will allow you to control from the the OMS' thrust vector (which is 10 degrees below the nose of the shuttle).

15. Stage to start the OMS.

16. Circularize the orbit.

Orbital Activities

- Press action group 3 to toggle the ladder and light inside the cargo bay

- Press 5 to release the payload

- When using the OMS, use the bottom docking port's control point

- When using the RCS, use the capsule's control point

Returning to Kerbin

1. Using the OMS control point, burn retrograde to deorbit

  • Deorbiting over the west part of the desert should get you close to KSC

2. Press 3 to retract everything

3. Try to keep the nose slightly above the horizon during re-entry, but try not to pitch up too much.

- The orbiter may flip if it has a lot of fuel in it, although flipping is usually caused by pitching up too fast and too much, which can be avoided.

Almost a perfect design. Not much that isn't accurate to the real thing and it looks amazing. :)

About the instructions, I flew it earlier and there is still room for error if you don't follow them perfectly.

Those were mainly for the heavier payloads, where fuel pretty tight. The funny thing is, as you can see, I didn't finish the "how to fly" for heavier payloads. :P

I sent 6 probes to orbit today.

3.5 tons in total and I still had more than 280 units of fuel and oxidizer left in the OMS tanks after circularizing the orbit.

What are your thoughts on using the "LV-T75" trick as the SSMEs? The larger nozzle of the T-30 looks closer to the real shuttle, but the lack of gimbal is a problem. With a T-45 clipped inside, you get the benefit of gimbaling and higher thrust (if you want it -- you might use the thrust limiter on the T-30s to make them mostly cosmetic).

I think that it would be too heavy. I don't get why the LV-T45 has a smaller nozzle than the LV-T30. They have the same specific impluse, and T30 probably has higher thrust because of its larger turbopump assembly.
