Stryker-III

A dark shape against the sky, the Stryker-III is a formidable three-stage rocket, a bold statement in black with striking red accents. Designed for ambitious interplanetary travel, its mission is to bridge the vast distance between its home planet of Droo and the distant gas giant, Tydos.

The journey begins with the roar of Stage 1. Propelling the rocket skyward are four powerful LoxRipper engines. These full-flow staged combustion engines use kerolox fuel, generating an impressive specific impulse (ISP) of 308 at sea level and 318 in the vacuum of space. Their combined thrust effortlessly lifts the massive vehicle, pushing it through Droo's atmosphere with incredible force.

After the first stage separates, the single T8i engine of Stage 2 takes over. This engine, fueled by highly efficient hydrolox, is optimized for performance in the upper atmosphere and beyond. It boasts a specific impulse of 399 at sea level and an even more remarkable 449 in a vacuum, providing the crucial velocity needed to escape Droo's gravitational pull and set a course for the distant Tydos.

The final and most advanced phase of the mission is powered by Stage 3. This stage features a nuclear propulsion system, centered around the cutting-edge GX engine. Using liquid hydrogen as its propellant, this engine is designed for maximum efficiency in the deep void of space. While its sea-level ISP is 669 (a testament to its power, but it’s not meant for atmospheric use), its true potential shines in a vacuum, where it reaches an astonishing ISP of 953. This incredible efficiency allows the Stryker-III to execute its long-duration cruise to Tydos. Upon arrival, it will perform the necessary maneuvers to enter orbit around the gas giant, ready to begin its mission of exploration and study of Tydos and its many moons. The Stryker-III is a testament to advanced engineering, built to conquer the final frontier.
