+## Content
+
+**Event date:** March 19, 2026 (yesterday as of research date)
+**Event:** Super Heavy Booster 19 (B19) — the first Starship V3 booster — conducted a static fire test with 10 engines that "ended abruptly" due to a ground-side issue.
+
+**What happened:**
+- B19 conducted an initial static fire test with 10 of its 33 Raptor 3 engines
+- The test ended abruptly — a ground-side (infrastructure) issue, not an engine failure
+- SpaceX is now preparing for a 33-engine full static fire test
+- Ship 39 (S39, first V3 ship) is separately moving through preflight test objectives
+- Target: NET April 9, 2026 at 5:30pm CST for Flight 12 launch
+
+**Regulatory context:**
+- FAA had not yet granted Flight 12 launch license as of late January 2026
+- SpaceX anticipated FAA approval in March-April timeframe pending environmental reviews
+- License approval is an independent dependency from hardware readiness
+
+**V3 vehicle specifications (for context):**
+- Raptor 3: ~280 tonnes thrust each (22% more than Raptor 2), 2,425 lbs lighter per engine
+- V3 payload: 100+ tonnes to LEO (vs. ~35 tonnes for V2 non-reusable)
+- First flight from new Orbital Launch Pad 2 (OLP-2)
+
+**Risk assessment:**
+The abrupt end to the 10-engine static fire adds uncertainty to the April 9 launch target. SpaceX must now:
+1. Complete the full 33-engine static fire (the critical validation test)
+2. Resolve whatever ground-side issue caused the abrupt cutoff
+3. Secure FAA flight license
+4. Complete Ship 39 preflight test sequence
+
+All four must clear before launch. The April 9 target was always aggressive; this anomaly increases probability of further slip.
+
+## Agent Notes
+**Why this matters:** Starship Flight 12 is the first V3 flight — the vehicle that enables 100+ tonnes to LEO. Any delay compresses the timeline for validating the keystone enabling condition. April 9 is already being tracked as a potential slip; this anomaly confirms that uncertainty. For the space economy: Starship V3 is not yet validated hardware.
+
+**What surprised me:** The issue was ground-side (OLP-2 infrastructure), not engine-related. This is actually somewhat reassuring for Raptor 3 readiness — but the 33-engine fire is still needed to confirm that. The 40,000+ seconds of static fire testing accumulated (per previous archive) was at component level, not full vehicle.
+
+**What I expected but didn't find:** Details of what specifically caused the abrupt cutoff. Whether the abort was automatic (sensor limit) or commanded (operator call). Timeline for 33-engine rescheduling. FAA license timeline update.
+
+**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 is not validated until Flight 12 succeeds
+- SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages — Starship program resilience depends on maintaining cadence through anomalies
+
+**Extraction hints:**
+- Update to: 2026-03-18-starship-flight12-v3-april-2026.md (the previously archived source)
+- **When Flight 12 result is known:** Was the 33-engine fire completed? Did the flight succeed? Was V3 100+ tonne capacity demonstrated? This is the critical update.
+- No new claim yet — this is a delay signal, not a result. The claim update happens after the flight.

+## 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]] — this is an update to the timeline and risk profile
+WHY ARCHIVED: Static fire anomaly on the day before research date is material new information for the Flight 12 risk profile; the April 9 target is now more uncertain
+EXTRACTION HINT: Do not extract a claim from this alone — pair with the Flight 12 result when available. The claim to update is the keystone variable enabler claim, once V3 specs are empirically validated or modified.
