SpaceX has just released a massive new list of changes in Starship V3, which is now scheduled to launch on May 19th:

Super Heavy V3 Changes
Grid Fin Redesign:
• Reduced from 4 fins to 3
• Each fin is now: 50% larger, stronger, repositioned for better catching/lifting
• Lowered on booster to reduce heat exposure during hot staging
• Fin hardware moved inside fuel tank for protection

Integrated Hot Stage:
• Removes the old disposable interstage shield
• Booster dome now directly exposed to upper-stage engine ignition
• Tank pressure + steel shielding protect structure
• Interstage actuators retract after separation for protection

New Fuel Transfer System:
• Massive redesign of fuel transfer tube
• Roughly the size of a Falcon 9 first stage
• Allows: simultaneous startup of all 33 Raptors, faster and more reliable flip maneuvers

Engine Bay / Thermal Protection Changes:
• Engine shrouds removed entirely
• New shielding added between engines
• Propulsion + avionics more tightly integrated
• CO₂ fire suppression system removed
• Simpler and lighter aft section

Propellant Loading Improvements:
• Moved from 1 quick disconnect to 2 separate systems
• Adds redundancy
• Reduces complexity of pad interfaces

Starship V3 Changes
Completely Redesigned Propulsion System:
• Clean-sheet redesign
• Supports: new Raptor startup method, larger propellant volume and improved reaction control system
• Reduces trapped/leaked propellant risk

Aft Section Simplification:
• Fluid + electrical systems rerouted
• Engine shrouds deleted
• Large aft cavity removed

Flap Actuation Upgrade:
• Changed from: 2 actuators per flap to 1 actuator with 3 motors
• Improves:, redundancy, mass efficiency, cost

Faster Starlink Deployment:
• Upgraded PEZ dispenser
• Faster satellite deployment speeds

Long-Duration Spaceflight Capability:
• New systems added for: long orbital coasts, orbital refueling, cryogenic fluid management, vacuum, insulated header systems and high-voltage cryogenic recirculation

Ship-to-Ship Docking + Refueling:
• Added 4 docking drogues
• Added propellant transfer connections
• Directly supports in-space refueling architecture

Avionics Upgrades
Massive Electrical System Upgrade:
• ~60 custom avionics units
• Batteries/inverters/high-voltage systems integrated together
• ~9 MW peak power capability

Better Navigation + Redundancy:
• New multi-sensor navigation system
• Designed for precision autonomous flight

Propellant Monitoring in Space:
• New RF sensors measure propellant levels in microgravity
• Important for orbital refueling missions

Camera + Connectivity Upgrades:
• ~50 onboard camera views
• 480 Mbps Starlink connectivity onboard
• Low-latency redundant communications

Raptor 3 Engine Changes
Higher Thrust:
• Sea-level Raptors:
• Increased from:
230 tf → 250 tf
507k lbf → 551k lbf

Vacuum Raptors:
Increased from:
258 tf → 275 tf
568k lbf → 606k lbf

Lower Mass:
• Sea-level engine mass reduced: 1630 kg → 1525 kg

Simpler Design:
• Sensors/controllers integrated into engine body
• Removes need for engine shrouds
• New ignition system for all variants
• Huge Vehicle-Level Weight Savings
• ~1 ton saved per engine across vehicle systems

Launch Pad 2 Upgrades (Starbase)
Faster Propellant Loading:
• Larger propellant farm
• More pumps
• Faster fueling operations

Chopstick Improvements:
• Shorter arms for faster movement
• Switched from hydraulic → electromechanical actuators
• Better reliability + redundancy

Stronger Quick Disconnect Arm:
• Reinforced and redesigned
• Swings farther away during launch

Launch Mount Redesign:
• Better load handling
• Improved launch protection
• Improved throwback reliability

New Flame Diverter System:
• Bidirectional flame diverter
• Designed to eliminate ablation/refurbishment after launch

Hardened Propellant Systems:
• Methane and oxygen systems separated
• Valves/filters moved into protected bunker
• Improves safety and reliability

SpaceX: "Together, these new elements are designed to enable a step-change in Starship capabilities and aim to unlock the vehicle’s core functions, including full and rapid reuse, in-space propellant transfer, deployment of Starlink satellites and orbital data centers, and the ability to send people and cargo to the Moon and Mars."

STARSHIP FLIGHT 12 NET MAY 19 🚨
Overnight, SpaceX teams destacked Ship 39 from Booster 19, with a rollback planned for this morning. Previous NOTAMs have been canceled, and new ones just popped up for May 19th onwards.

@SpaceX
Launch rehearsal complete. During a flight-like countdown, more than 5,000 metric tonnes of propellant were loaded on the fully stacked Starship and Super Heavy V3 vehicles for the first time

@WatchersTank
STARSHIP WDR COMPLETED! 🚨
SpaceX teams just wrapped up what appears to be a successful WDR. Road closures for tomorrow have been cancelled on the Starbase website, so it looks like testing is complete. A NOTAM just popped up for May 15th for Flight 12!

You'll Thank Me Later! The SpaceX Starhip transport barge has just been fitted with a brand new roof enclosure, and looks just about fully finished. This barge should soon transport some of the first Superheavy boosters and ships from Starbase to the Cape!

OMNIHASH: Jsi pozadu oproti soucasnemu state-of-the-art AI hype. To nebude cloud ve smyslu klasickeho AWS, ale "neocloud", coz by se amatersky (bez potrbneho hype) dalo nazvat "pronajimat servery na AI". ;-)

DZODZO: Klidne to ber jako genialni, predem pripravenou a promyslenou strategii. Ono je dokonce mozne, ze na tom celkove skurecne neco vydelaji, i kdyz to se ukaze az casem. Teda, ukazalo by, kdyby zase vsechna cisla nebyla utajena, zavadejici, nebo proste uplne vymyslena. Ale jako business na vydelavani penez to treba vyjde. Jenze pro xAI, jako "spickovy AI lab, ktery to vsem ukaze," nepusobi tak presvedcive, kdyz na uceni dokazou vyuzit jen zlomek dostupneho HW (a to maji k dispozici best-case monolit v jedne lokalite) a o inferenci je tak "velky" zajem, ze radeji prodaji vetsinu kapacity konkurenci.
