SpaceX’s Secret Plan for Starship Flight 12 Revealed! Beyond What We Expected…

April. This is the month when Starship completed its first full integrated flight in 2023. Now, three years later, we are getting very close to the next major milestone, Flight 12. The first flight of version 3. It could even happen on April 20th. To reach this goal, SpaceX is preparing an ambitious plan for the flight. One that could go beyond expectations. So how will this plan unfold? Let's find out in today's episode of Great SpaceX. We are calling Flight 12 the first version 3 flight. It sounds new, but in reality, it's not very different from recent flights. The reason is simple. SpaceX wants to test the upgrades in V3, so the overall flight profile will remain similar to version 2. The rocket will launch, separate, the booster will return and land in the ocean, while the ship will approach orbit, deploy its payload, re-enter, and land in the ocean. So what's different? There is more happening than it may seem. Let's start with the mission. After several tests using dummy payloads, SpaceX now appears ready to move to the next step. An FCC license update in February showed that SpaceX plans to carry out a suborbital payload deployment test. The license takes effect on April 7th, 2026, which aligns well with the expected timing of Flight 12. This time, the payloads are not just test masses. They are likely to be functional. The FCC stated, To further test the payload deployment mechanism of the Starship vehicle, SpaceX seeks special temporary authority to launch and operate space stations on mass simulators for upcoming Starship Super Heavy test flights. After launch, SpaceX will use these space stations to communicate with SpaceX's satellite constellation and Earth Station network for a short duration, about one hour before they re-enter and burn up. To support this mission, the payloads will include upgrades such as cameras and communication antennas. These systems will allow them to connect with other spacecraft in orbit, especially SpaceX's Starlink network. This could be an early test for a new type of satellite. It might be Starlink version 3, an upgrade to the current system. It could also be part of a much larger satellite network that SpaceX plans to build for space-based data services. Another possibility is that it includes new hardware, such as the recently introduced TerraFab chip. Right now, it's not fully confirmed if SpaceX will carry out this plan. We should know more soon once the payloads are installed. This will likely happen after S39 completes its static fire test and follow-up inspections. What do you think about this plan?

At the same time, new developments may emerge from ongoing upgrades to the vehicle itself. While the overall flight profile will remain similar to recent missions, Flight 12 is expected to operate differently due to the introduction of several new components. Let's start at the bottom with the 33 engines. These are the black engines of the third version of the Raptor family, known as Raptor 3. After a long wait, this version was tested during B19's static fire attempt, although it did not reach full expected performance. We'll need to wait for the next test when all 33 engines are installed to fully see its power. S39 is also being prepared with engines for testing at Massey. These upgrades focus on improving performances during flight. With a simpler design, the engines are expected to increase efficiency and help demonstrate higher payload capability in the future. Beyond power, control is also important. During flight, the Raptor engines must guide the vehicle, keep it stable, and support stage separation. After separation, the engines continue to control each stage. The booster engines guide it through descent and landing in the ocean. The ship engines push it toward orbit, support payload deployment, and then guide it through re-entry and landing. In the future, these engines will also support landing with the Mechazilla arms. Another key improvement in Raptor 3 is reliability. Its simpler design makes it different from earlier versions and many other rocket engines. This reflects SpaceX's goal to simplify production, operation, and reuse. A simpler system can also reduce risk and improve reliability. Now let's move up to the vehicle body. Externally, the changes are easy to see. SpaceX is aiming for a higher angle of attack during landing. This allows the vehicle to use air resistance to slow down, reducing the need for fuel and saving it for later use. However, this approach is more demanding and requires stronger materials. After learning from earlier failures, SpaceX is building B-19 and S-39 with improved strength. The goal is to increase durability and ensure safe landings under more difficult conditions. Inside the booster, there's also an upgrade called a transfer tube. It's larger and more durable and it helps improve fuel flow to the engines. It may also support better control during the flip maneuver. Moving further up, there's also another major set of upgrades. The grid fins have been redesigned. They are now three instead of four and they are larger with a new shape. These changes should improve control during descent and increase landing accuracy, especially for future catches using the Mechazilla arms. The position of the grid fins has also changed. They are now placed farther from the hot staging area to reduce the effects of separation. They also include a catching point showing their role in future landing methods. The hot staging system itself has also been improved. It's no longer a separate heavy ring but is now part of the booster structure. This design is improved by the Soviet N1 rocket. The goal is to reduce mass, simplify the system, remove the need to discard parts, and improve how heat and pressure are managed during separation. This upgrade will affect both stages and improve overall efficiency. Now, moving to the upper stage, we see some of the most important upgrades, especially to the heat shield. S-39 appears to have a fully covered heat shield with no visible gaps. SpaceX has installed tiles across the entire surface to better handle the extreme heat of re-entry. The tiles also appear to use improved materials based on their color and surface finish. These changes likely increase durability and heat resistance. The system may still use a protective layer underneath to block heat from reaching internal structures. Metal tiles seem to have been removed, possibly because they showed signs of wear and oxidation in recent flights. In addition, Ship V3 includes a new catching point system. It will not be used for landing in this flight, but it will be tested to see how it survives the mission. This will support future landing attempts at Starbase. And the upgrades don't stop at the vehicle. They extend all the way to the ground, into the infrastructure that will ultimately determine how often, how reliably, and how quickly Starship can fly. Because a system like this is only as strong as the platform that supports it. And with Pad 2, SpaceX is building for scale. Construction began in 2024, replacing the old suborbital launch site with something far more capable. From the outset, Pad 2 was conceived not as an iteration of Pad 1, but as a step change. A response to everything learned so far. One of the most visible upgrades is the Flame Trench System. After proving its effectiveness at Massey, the concept has been expanded into a dual trench configuration designed to better manage exhaust, reduce erosion, and protect critical infrastructure during high-energy launches. The orbital launch mount has also been reimagined. Dawn is the six-legged structure. In its place, a more streamlined stand, simpler in form, but engineered for greater strength and operational efficiency. It's a shift toward durability, toward repeatability, toward a system that can withstand not just launches, but frequent launches. And beneath it, the Booster QD System, or Quick Disconnect, has undergone significant refinement, targeting faster, more reliable propellant transfer, and cleaner separation at liftoff. The tower tells a similar story. The chopsticks have been shortened, reducing mass, tightening control, and improving responsiveness. At the same time, the SQD System, or Shift Quick Disconnect, has been upgraded to better support rapid integration and turnaround. But these aren't just design changes on paper. They've been tested relentlessly. Lifting, lowering, rotating, opening and closing the arms, running the water deluge system through full cycles, simulating the stresses of launch and recovery. And recently, with B19, something even more telling emerged. Faster fueling. A small detail, perhaps, but one that signals a larger objective. Because in a fully operational system, speed on the ground becomes just as important as performance in the air. Pad 2 represents that shift. It's not just a launch site, it's a proving ground. A platform where new ideas are not only implemented, but validated. A template for what future pads may become as Starship moves toward higher cadence and sustained operations. And it's built with the next generation in mind. Initially, it'll support testing for V3 of the vehicle. But beyond that, it's designed for full operational flow, which involves fueling, connection, disconnection, and the management of extreme thermal and pressure loads at liftoff. Landing operations are not yet part of its active role. Not directly. But even here, preparation is underway. Tests involving the lifting and positioning of both stages are already probing a critical question. How precisely can the chopstick arms interface with the vehicle's catch points? Because one day, that interaction won't be a test. It'll be routine. And that's the deeper purpose of Pad 2. Not a single launch. Not a single milestone. But a system capable of sustaining many. A system designed to answer a far more important question. Can Starship operate not just once, but continuously? As Flight 12 approaches and more systems come online, that answer will begin to take shape. Not in a single moment, but across every test, every cycle, every launch that follows. It's clear that SpaceX is approaching Flight 12 with intent, layering complexity, testing boundaries, and quietly assembling a mission shaped by both ambition and uncertainty. Some elements are already visible, others remain deliberately concealed. Because beneath this new iteration lies a series of major upgrades, changes that are rarely introduced without purpose. Every modification, every refinement is aimed at solving a specific constraint, advancing a specific capability. And this time, the scope is unmistakable. This is not just a single upgrade. It's a system-wide evolution. From the booster to the ship, from propulsion to ground infrastructure, and even the launch pad itself, every element is being refined in parallel. That level of coordination points to something more significant. This flight is not about testing a single feature, but about validating how the entire system performs as one integrated architecture. And Flight 12 may mark the milestone where integration moves from concept to demonstrated capability. And that brings us to the end of today's episode. Thank you so much for tuning in. As always, this has been Kevin from GreatSpaceX. Until next time, keep looking up!
