- Squad (stock). Root part is fairingSize2. (DLC REQUIRED)
Replica of
Proton Rocket (Russia)
Description
With Kerbodyne S3 and S4 series components starting to become a serious competition in the heavy launchcategory, Rockomax and Jeb’s Junkyard & Spacecraft Parts co-developed an alternative launch system that only rely upon their own hardware. The end result is the Butalae launch system, which have the additional benefit of easily transport on rails.
Due to the out-of-the-way location of Woomerang Design Bureau, these become the ideal launch vehicle for the WDB designed space station modules, making it a popular workhorse during the early space program.
Maker’s Note
The Proton replica had been one of my earliest attempt to make a good
launcher. Part of the reason why it took so long is due to the choice of first stage thrusters – Most other clones ended up with Vector, which is definitely overkilled for a launcher which is rated for only 23t in real life… not to mention once you factor the cost, it becomes very expensive.
Then there’s the 1.6 rebalance, which makes the Skiff not as viable for such purpose due to weight increase. However, the RK-7+RV-1 also ended up rebalanced, and have better stats as a first stage launcher.
