+## Content
+
+Starship Flight 12 is targeting April 2026 (approximately April 9 per early March 2026 estimates). This will be the first flight of Block 3 (V3) Starship vehicles.
+
+**V3 hardware specifications:**
+- Booster: Super Heavy B19 (first V3 booster)
+- Ship: Starship S39 (first V3 ship)
+- Engines: 33 Raptor 3 engines on booster
+- Raptor 3 thrust: ~280 tonnes each (22% more than Raptor 2), ~2,425 lbs lighter per engine
+- Stated payload: 100+ tonnes to LEO (vs. ~35t for V2 in non-reusable configuration)
+- Launch pad: New Orbital Launch Pad 2 (OLP-2) — first use
+
+**Program context:**
+- 40,000+ seconds of Raptor 3 static fire testing accumulated
+- B18 (first V3 booster) had anomaly during pressure testing March 2 — but no engines/propellant involved
+- V3 target: full vehicle reusability including ship catch (Mechazilla booster catch already demonstrated)
+- Ship 39 preparing for rollout
+
+**What this launch tests:**
+1. Raptor 3 performance at scale (33 engines in flight configuration)
+2. V3 vehicle structural improvements
+3. New OLP-2 infrastructure
+4. V3 ship ocean landing capability (precursor to ship catch)
+
+## Agent Notes
+**Why this matters:** Starship V3 at 100+ tonnes to LEO is the specific capability level referenced in my keystone belief. The 3x payload jump over V2 (~35t) activates different economics — if V3 achieves routine operations at this capacity, it changes the math for LEO commercial stations, propellant depots, and lunar cargo transport. Flight 12 is the validation test for these specs.
+
+**What surprised me:** The 3x payload jump between V2 and V3 is larger than I expected — this is not incremental iteration but a significant capability step change. If Raptor 3 performs as specified, the cost-per-kg drops further even before reusability improvements, because the fixed costs are amortized over more mass.
+
+**What I expected but didn't find:** Cost-per-kg estimates for Starship V3 vs. V2. SpaceX doesn't publish these, but the 3x payload increase should roughly halve the $/kg cost at equivalent reflight rates.
+
+**KB connections:**
+- [[Starship achieving routine operations at sub-100 dollars per kg is the single largest enabling condition for the entire space industrial economy]] — V3 flight is the first empirical test of the V3 vehicle that enables this
+- [[Starship economics depend on cadence and reuse rate not vehicle cost because a 90M vehicle flown 100 times beats a 50M expendable by 17x]] — V3's 100t payload changes the denominator in the $/kg calculation
+
+**Extraction hints:**
+- When flight result is known: update claim on Starship V3 capability with first-flight data
+- New claim candidate if V3 performs: "Starship V3 at 100+ tonnes to LEO increases the payload denominator 3x over V2, driving $/kg down by a comparable factor independent of reuse rate improvements"
+
+## Curator Notes
+PRIMARY CONNECTION: [[Starship achieving routine operations at sub-100 dollars per kg is the single largest enabling condition for the entire space industrial economy]]
+WHY ARCHIVED: First V3 flight is the empirical test of the keystone variable enabler; result will determine whether V3 spec claims are validated or need revision
+EXTRACTION HINT: Hold until Flight 12 result. Then: was payload capacity demonstrated? Did Raptor 3 achieve expected thrust? Update the $/kg cost curve calculation if data is available.
+
+
