## Content

**V3 compound economics (theoretical):**
- Payload to LEO: >100 MT reusable (V2: ~35 MT) — 3x increase
- Raptor 3: 4x cheaper to manufacture than Raptor 1 (SpaceX reported)
- Two launch pads at Starbase (Pad 1 + Pad 2): doubles theoretical annual launch capacity
- V3 flight unit (Booster 19 + Ship 39): both completed full-duration static fires April 15-16, 2026 without anomalies
- Flight 12 targeting first half of May 2026

**Updated $/kg projections (using V3's 3x payload multiplier applied to KB's V2 baselines):**
- V3 single-use: ~$900/kg (100 MT payload, ~$90M vehicle cost)
- V3 at 6 reuse cycles: ~$25-30/kg (vs V2's $78-94/kg — approximately 3x improvement)
- V3 at 70 reuse cycles: ~$4-5/kg (vs V2's $13-20/kg)
- **V3 crosses $100/kg threshold at approximately 2-3 reuse cycles** — dramatically lower than V2's 6+
- SpaceX long-term target: $10/kg marginal cost with airline-like operations (Musk statement)
- Analyst consensus: $100-500/kg "once operational at full cadence" (SpaceNexus 2026)

**The FAA cadence bottleneck (structural finding):**
- FAA approved 25 Starship launches/year at Boca Chica (up from prior 5-launch cap) — announced early 2026
- BUT: post-anomaly FAA investigations have historically run 2-5 months
- Flight 7 (grounded ~4 months), subsequent flights constrained by investigation pace
- 2026 prediction market signal: "<5 Starship launches reaching space in 2026" at near-coin-flip probability (Lines.com, as of April 2026)
- SpaceX has 44 Starship missions in their stated 2026 plan; market expects ~5 or fewer

**The structural constraint mechanism:**
The 25-launch FAA approval assumes no anomalies. Each anomaly resets the clock. With a new vehicle generation (V3 has never flown), anomaly probability is elevated precisely when cadence would otherwise accelerate. The mathematical problem: to achieve the reuse counts needed for low $/kg, you need many flights per year; but many flights per year requires no anomalies; but new vehicles have elevated anomaly rates; therefore the cost-reduction timeline extends beyond what vehicle economics alone would suggest.

The analog: V2 had Flight 7 anomaly (lost upper stage, ~4-month grounding), Flight 8 anomaly, etc. Each anomaly offset gains from increasing cadence. V3 is starting its learning curve from zero.

**Critical question for Belief 2 (launch cost keystone):**
If Flight 12 (V3 debut) has a nominal upper stage reentry AND maintains the "headline success/operational failure" pattern (booster caught, upper stage lost), does that trigger another multi-month FAA investigation at the very moment V3 cadence should be building? The previous two V2-era mishaps created ~4-8 month gaps in cadence. Applied to V3, this would push the "6 reuse cycles" milestone from 2027 to 2028-2029.

**Implication for KBclaims:**
- The KB's $78-94/kg claim (6 reuse cycles) was framed around V2 economics. V3's 3x payload improvement means the EQUIVALENT cost threshold (sub-$100/kg) is achievable at 2-3 reuse cycles.
- But the TIMELINE to those reuse cycles depends on cadence, which depends on investigation-free operations.
- Best case (no anomalies): V3 could reach sub-$100/kg in 2027 with 2-3 successful flights
- Realistic case (1-2 anomalies): sub-$100/kg in 2028-2029
- This matters for ODC Gate 1 clearance (Google feasibility study: $200/kg threshold for gigawatt-scale), ISRU economics, and the megastructure bootstrapping thesis

## Agent Notes

**Why this matters:** The KB has robust claims about Starship economics ($/kg thresholds) and an implicit timeline of "sub-$100/kg by late 2020s." V3's tripled payload fundamentally changes when that threshold is achievable IN VEHICLE TERMS, but the FAA investigation cycle is the operational bottleneck that the economics models don't capture. This is the most important nuance to add to the KB's launch economics claims.

**What surprised me:** The 25-launch FAA approval for Starship exists — I didn't know the FAA had already approved this cadence. What constrains SpaceX isn't regulatory approval but post-anomaly investigation requirements. The bottleneck is investigation timelines, not license approval. This is a different governance failure mode from the standard "FAA blocks launches" narrative.

**What I expected but didn't find:** Specific V3 $/kg projections from SpaceX or analyst reports. The analysis above is derived from applying V3's known performance improvements (3x payload, 4x cheaper engines) to the KB's existing V2-based projections. No analyst has published a comprehensive V3-specific cost model yet. Flight 12's results will be the first real data.

**KB connections:**
- Directly relevant to: [[launch cost reduction is the keystone variable that unlocks every downstream space industry at specific price thresholds]] — V3 changes WHEN the thresholds are crossed, not WHETHER
- Relevant to: [[Starship achieving routine operations at sub-100 dollars per kg is the single largest enabling condition for the entire space industrial economy]] — V3 lowers the reuse count needed to reach this, but extends the timeline via investigation cycles
- Relevant to: Pattern 2 (institutional timelines slipping) — SpaceX's own Starship cadence faces structural investigation-cycle constraints

**Extraction hints:**
1. CLAIM CANDIDATE: "Starship V3's tripled payload capacity (>100 MT vs V2's 35 MT) means the $100/kg launch cost threshold is achievable at 2-3 reuse cycles rather than V2's 6+ — a dramatic lowering of the threshold entry point that advances the cost timeline by 2-3 years relative to V2-based projections, subject to FAA investigation cycle constraints"
2. CLAIM CANDIDATE: "FAA mishap investigation cycles (2-5 months per anomaly) are the structural bottleneck limiting Starship cost reduction, not vehicle economics or regulatory approval — the 25-launch/year FAA approval is a ceiling constrained by the operational reality that new vehicle generations have elevated anomaly rates precisely when cadence should be building"

## 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: V3's payload tripling fundamentally changes the timeline for threshold crossing — this needs to update multiple KB claims based on V2 economics. The FAA investigation bottleneck is the new constraint that limits the improvement.
EXTRACTION HINT: Two claims needed: (1) V3 cost improvement (the positive finding), (2) FAA investigation bottleneck (the constraint). Both need to be extracted together for the full picture. Do not extract the improvement without the constraint.
