Auto Credit Based on AvSpace's Atlas V 521

Atlas V is an expendable launch system and the fifth major version in the Atlas rocket family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing.
This is the 531 variant

Payload to LDO (Low Droo Orbit): 15.5 tons
Payload to Droo Polar Orbit: 12.8 tons
Payload to Droo Geosynchronous Orbit: 3 tons
Payload to Droo Escape: 4.9 tons

Yep, I will make those Atlas V variants


Applied Seamless Edge on the fairing base
Tweaked the RD-180 (Atlas V first stage) nozzle color
Tweaked the first stage height (it was 1 meter too tall)
Once again, tweaked the SRB's position

Also, the replica may not be 100% accurate, and I use tinker panel only for Part Collisions and Mass Scale for the ULA logo, Atlas logo, and flag

    @AvSpace Its a very good Rocket, all il saying is Its very hard to achieve Orbit, with an craft That is super heavy!

    the upper stage (Centaur) has a very small thrust-to-weight ratio, so it will be hard to get into orbit, especially with the heavy payload. the engine (RL10) has the exact same amount of thrust as the real ones, but efficiency and other stuffs are inaccurate. i can make it accurate but that requires XML i think, and i dont want to use it because i want this craft to be vanilla, after all i dont know how to use XML

    well just keep the throttle at 100% and gradually change your pitch until you get into orbit. or you can use Kelly’s Auto-Launch program

    but if you’re saying that the fuel capacity is too low, i cant do anything about that. and i dont want to clip fuel tanks, because thats like, cheating. i can XML it to have more fuel capacity inside, but as i said before, i dont know how to use XML, also im playing SR2 on mobile so XML-ing will be kinda hard

    there will be an Atlas V version with 2 engines on the upper stage, so it will be easier for you to achieve orbit, hopefully

    It's good but one thing Doesn't have enough thrust to get into orbit
