Usage
The Mammoth has the highest specific impulse at sea level of any liquid fuel engine, tied with that of its counterpart, the S3 KS-25 "Vector" Liquid Fuel Engine. This makes it an effective engine for first stages and SSTO vehicles. As noted in the product description, it is the highest-thrust single engine in the game.
There are no attachment nodes for placing additional stages beneath the engine cluster. This means that the Mammoth will almost always be found at the bottom of a vessel's first stage.
According to the part description. the engine is assembled from four S3 KS-25 "Vector" Liquid Fuel Engines. The Mammoth's Isp and thrust match this description. However, the Mammoth is one ton lighter and 46% cheaper, but has a much lower gimbal range, than four Vector engines.
After the CR-7 R.A.P.I.E.R. Engine, this is the second liquid fueled engine to use multiple nozzles. (Although the multi-nozzle RE-L10 "Poodle" Liquid Fuel Engine was introduced earlier, its two-nozzle model was not introduced until version 1.6.)
Trivia
KS-25 is a reference to RS-25, the official designation of the Space Shuttle Main Engines. The part, which uses four KS-25 engines, is inspired by the main engine component of the Space Launch System, which similarly uses four RS-25 engines. The part was introduced along with several other SLS-inspired parts.
Changes
- Cost increased from 5900 to 32400 (and made meaningful)
- Initial release
