The Griffin Rocket
The Griffin Rocket is a fully operational two-stage launch vehicle, showcasing Astrum Y's advanced engineering. The first stage, the Griffin Booster, delivers immense thrust for liftoff with its nine clustered engines working in perfect sync. Designed for reusability, the booster features landing legs and grid fins for precise, controlled descents, enabling cost-effective recovery and refurbishment. This innovative design ensures efficiency without compromising performance.
The second stage complements the booster by carrying payloads into various orbits, from LEO to GTO. It uses a single, high-efficiency engine for accurate orbital insertions. Lightweight and versatile, the second stage is built to accommodate a wide range of missions, such as satellite launches, research endeavors, and interplanetary objectives. Its modular structure allows customization to meet specific mission needs.
With its fully reusable, two-stage design, the Griffin Rocket represents a leap forward in space accessibility. Its Falcon 9-inspired approach blends innovation with affordability, supporting frequent launches with quick turnarounds. From deploying satellite constellations to fueling exploration dreams, the Griffin Rocket embodies Astrum Y's commitment to shaping the future of spaceflight.
Notes
This is not the finished craft, It's just meant to be a sort of preview although it can bring about 10 tons to orbit and be reused. I'm facing issues with the second stage engine and Grid fins. but just as spacex did this will go several iterations until its Perfect! Anyway please share any issues and upvote! Have a good one!

@Einstein100 Thanks a lot! appreciate it! oh and yes I am I just now posted a sort of thing that might actually work on this too but the Phoenix (craft I just posted) is not the mini starship

@AstrumY, BTW, it preforms really well, definitely a very cool rocket. It will make a good competitor for Eagle 5. And, are you still pursuing the “mini-starship” upper stage?

@Einstein100 Here are the instructions for operating the Griffin 9
Liftoff and Initial Climb
Ignite engines and launch. Climb straight up to an altitude of approximately 5 km.
Throttle Down and Begin Gravity Turn
Reduce throttle to 70% and gradually pitch east or west to a 70° angle. Hold this pattern and continue gradually increasing the pitch but never exceed 55°.
Stage Separation and Booster Maneuver
When your apoapsis exceeds 85 km, detach the second stage. Lock the booster retrograde and fire its engines until the trajectory in map mode shows the predicted landing point just behind the landing pad.
Second Stage Burn and Booster Descent
Switch to the second stage and perform a brief burn to raise its trajectory. Keep an eye on the booster as it approaches 75 km or below. Once it nears reentry, activate grid fins and guide it toward the landing pad.
Booster Landing and Orbit Completion
Carefully descend the booster using grid fins and engines for a soft landing on the pad. Immediately switch back to the second stage and complete its burn to achieve orbit!
