## Content

Both Starship V3 vehicles have completed full-duration static fire tests ahead of the first V3 flight:
- **Ship 39** (upper stage) — full static fire complete
- **Booster 19** (Super Heavy) — full static fire complete, all 33 Raptor 3 engines

SpaceX article confirms Pad 2 refinements at Starbase (Boca Chica) are complete. Flight 12 will be the first launch from Pad 2 (second orbital launch complex). V3 design features: Raptor 3 engines (no external plumbing), increased propellant capacity, targeting 100+ tonnes to LEO.

Launch timeline: targeting early May 2026 (slipped from March 9 → April 4 → current early May target).

From the spaceflightnow.com launch schedule (April 22, 2026): No Starship listed in the next 10 days of upcoming launches, consistent with early May target.

Prior V2 history: Flight 11 (October 13, 2025) — final V2, both vehicles splashed down in ocean. V3 is a clean-sheet next-generation design with Raptor 3 engines.

## Agent Notes
**Why this matters:** Static fire completion is the final technical gate before Flight 12 launch. The two-pad setup means SpaceX can increase Starship launch cadence significantly once operational — Pad 2 doubles their launch capacity at Starbase. Flight 12's results (especially upper stage reentry survival and tower catch attempt) will be the most important Starship data point for the cost-threshold analysis.

**What surprised me:** Both Ship and Booster completed full-duration static fires without anomalies (based on the article framing). Previous V2 development had multiple static fire anomalies. The clean completion of full-duration tests for both vehicles suggests V3 development has been more mature — consistent with Raptor 3's simplified design (no external plumbing = fewer failure points).

**What I expected but didn't find:** The specific payload target or mission profile for Flight 12. Is it carrying any commercial payload, or is it purely a test flight? The payload type would inform whether this flight accumulates commercial experience or remains developmental.

**KB connections:**
- Directly relevant to: Belief 2 (launch cost keystone, Starship $500/kg threshold)
- Relevant to: ODC Gate 1 clearance thesis (Starcloud-3 activation at ~$500/kg)
- Relevant to: Pattern 2 (institutional timelines slipping — even SpaceX's own schedule slips)

**Extraction hints:** Claim candidate: "Starship V3 (Ship 39/Booster 19) completed full static fires ahead of Flight 12, representing the final technical gate before V3's first launch from Pad 2 — the performance of which will provide the first real data on V3's 100+ tonne payload capacity and reuse economics."

**Context:** SpaceX has 44 Starship missions planned for 2026. Flight 12 would be the first from Pad 2 and the first V3. The Raptor 3 engine simplification (no external plumbing) is expected to improve reliability and reduce manufacturing cost — critical for the reuse economics model that drives the $500/kg cost trajectory.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Belief 2 (launch cost keystone) and Starship reuse economics
WHY ARCHIVED: V3 static fire completion marks final gate before Flight 12 — the first V3 data point for the $500/kg cost trajectory
EXTRACTION HINT: The Pad 2 capability is as important as V3 itself — two launch pads doubles annual Starship cadence potential, which is the learning curve driver
