## Content

**Starship IFT-12 Pre-flight Status (as of May 3, 2026):**

**Timeline:**
- NET: May 12, 2026, 22:30 UTC (daily windows through May 18, each ~2 hours)
- Regulatory: FCC license already granted through October 2026 — not a bottleneck
- Hardware: All gates cleared after challenging static fire campaign

**Vehicle Configuration — V3:**
- Booster 19 + Ship 39 = first V3 stack
- Both powered by Raptor 3 engines (SpaceX's most advanced)
- V3 stands 408 feet tall when stacked (4 feet taller than V2)
- First launch from Orbital Launch Pad 2 (OLP-2) — maiden flight of SpaceX's second Starbase launch complex

**Payload capacity improvement:**
- V2 (reusable): ~35 metric tons to LEO
- V3 (reusable): 100+ metric tons to LEO
- Improvement factor: ~3x
- This is not incremental — it changes the economics of Starship payload deployment at scale

**Raptor 3 specifics:**
- Higher thrust than Raptor 2
- Improved reliability
- Specific Isp improvement (exact figure not yet disclosed pre-flight)
- First flight demonstration will provide baseline performance data

**Hardware bottlenecks (significant):**

1. **10-engine static fire abort at 2.135 seconds** — Apex Combustor issues (gas generators for pad water deluge system). Roughly half the 10 test engines sustained mechanical damage and required replacement.

2. **33-engine attempt abort** — Sensor issue in ramp manifold.

3. **Full engine swap**: SpaceX replaced ALL 33 engines on Booster 19 with a fresh set drawn from Booster 20's allocation. This cascade means:
   - Booster 20 (targeted for IFT-13) is now working with a depleted engine inventory
   - IFT-13's timeline is implicitly affected (Booster 20 engine supply disrupted)
   - The two-flights-before-June-28 (FCC window) target may be at risk if engine production can't replenish Booster 20's allocation in time

4. **Successful 33-engine static fire**: April 15, 2026. Cleared the primary technical gate.

**Mission profile:**
- Both booster and ship targeting SPLASHDOWN (not tower catch)
- This is deliberate step-back from IFT-11's tower catch — validating V3 architecture before adding catch complexity
- Revised trajectory: southern Caribbean corridor (between Jamaica/Cuba, then St. Vincent/Grenada) — confirmed in May 2 archive

**Significance for Belief 2 (launch cost keystone):**
- If IFT-12 succeeds: 3x payload improvement at similar or better cost is the largest single Belief 2 update of 2026
- If V3 achieves stated performance: sub-$100/kg trajectory becomes substantially more concrete (100+ tons to LEO vs. 35 tons means cost per kg drops even if per-flight cost is similar)
- If V3 demonstrates routine operations: the 30-year attractor state timeline compresses

## Agent Notes
**Why this matters:** V3's 3x payload improvement is not a marginal upgrade — it changes what's economically feasible with Starship. A 100-ton payload capacity at sub-$100/kg means propellant depots, commercial stations, and large telescope missions all become viable in single launches rather than requiring multiple flights. The OLP-2 debut also matters for cadence: two launch pads enable faster launch rates, directly affecting the flywheel.

**What surprised me:** The engine swap cascade to Booster 20 is more significant than I expected. Replacing all 33 engines on Booster 19 from Booster 20's allocation directly threatens the two-flights-before-June-28 target. This is a hidden timeline risk that the NET May 12 date doesn't reveal.

**What I expected but didn't find:** Specific Raptor 3 Isp values pre-flight. The IFT-12 flight itself will provide the first public baseline for Raptor 3 performance.

**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's 3x payload improvement moves this closer
- [[Starship economics depend on cadence and reuse rate not vehicle cost because a 90M vehicle flown 100 times beats a 50M expendable by 17x]] — OLP-2 second pad increases cadence potential
- SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages — engine production rate is the new constraint visible in this data

**Extraction hints:**
1. "Starship V3's 3x payload improvement (V2: ~35 tons reusable to LEO; V3: 100+ tons reusable) — if validated by IFT-12 — is the single largest per-vehicle capability jump in Starship's development history, potentially reducing per-kg cost at scale even if per-flight cost is similar"
2. "SpaceX's Booster 19 static fire campaign required replacing all 33 Raptor 3 engines (drawn from Booster 20's allocation), revealing that engine production rate is a binding constraint on Starship's two-flights-before-June-28 target — cascading timeline risk not visible in launch date announcements"
3. Confidence on V3 performance: experimental (NET May 12; data pending)

**Context:** IFT-11 (V2, March 2026) achieved booster catch. IFT-12 (V3) is a deliberate step back — no catch, splashdown for both — to validate the new architecture. If IFT-12 succeeds, IFT-13 (Booster 20) would be the first V3 booster catch attempt. But Booster 20's engine supply is now depleted from Booster 19's rebuild.

## Curator Notes (structured handoff for extractor)
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: The 3x V3 payload improvement is a potential Belief 2 update event; the engine swap cascade is a hidden production constraint not visible in headline launch date coverage. Both matter for KB claims about Starship economics and cadence.
EXTRACTION HINT: Focus on two extractable claims: (1) V3 3x payload jump and economic implications; (2) engine production rate as the new Starship scaling bottleneck. The IFT-12 outcome will determine whether (1) becomes a confirmed or experimental claim.
