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
