The RK-7 "Kodiak" is a liquid fueled engine similar in performance to the LV-T30 "Reliant" Liquid Fuel Engine, but with a "Russian" theme. It allows for greater visual and thematic variety in Making History scenarios, and usually is used in conjunction with the RV-1 vernier.
Usage
The RK-7's thrust, mass, Isp, and lack of vectoring make it almost identical (if more expensive) than the LV-T30, meaning it can in principle be used in the same situations. The high cost and position on the tech tree, however, make it an inferior choice in most situations.
Product description
| “ | A bear of an engine. This quad-nozzled beast comes with multiple cowling options, and no gimbal. Don’t forget those verniers. — Reaction Systems Ltd |
” |
Variants
As of version 1.4.1 this engine has three models that can be switched in the editor: bare, 1.5 m, and and 1.875 m.
Trivia
While bears are often used as a symbol of Russia, [kodiaks] live exclusively in the United States.
Real-world comparison
The RK-7 was inspired by the Russian RD-107 engine.
