## Content

SpaceX completed the first-ever firing of a V3 Starship Booster on March 19, 2026. Key details:

**The test:**
- 10-engine partial static fire on Booster 19 (B19) at Boca Chica Pad 2
- Engine type: Raptor 3 (first generation of V3 Raptor engines)
- Duration: Shorter than expected; ended early due to ground support equipment (GSE) issue
- This is the **first time any V3 Raptor 3 engine has been fired on a complete vehicle**

**Current status (as of March 19):**
- 23 additional Raptor 3 engines still need installation for the full 33-engine complement
- Full 33-engine static fire is the next required test
- Ship 39 (the matching upper stage) still completing its own testing campaign
- Flight 12 target: Mid-to-late April 2026 (April 9 target previously eliminated)

**V3 significance:**
- Booster 19 is the first V3 Starship booster (upgraded from V2)
- Raptor 3 engines represent significant thrust and efficiency improvements
- 100+ tonne payload target to LEO (vs. ~20-100t for V2 versions)
- Flight 12 will be the "first ever V3 test flight" — both vehicle and engine generation are new

**Pattern 2 continuity:**
- Original April 9 launch target eliminated
- Current target: mid-to-late April
- The 10-engine static fire was "shorter than expected" due to GSE issue
- Full 33-engine static fire is still pending with 23 engines still to install

## Agent Notes
**Why this matters:** The first V3 Raptor 3 engine firing is a genuine milestone — the V3 paradigm exists physically, not just on paper. But the partial test (10 of 33 engines, short duration, early stop) and the remaining 23-engine installation requirement means the critical qualification test (full 33-engine) hasn't happened. The V3 → Flight 12 → April launch sequence has multiple remaining steps.

**What surprised me:** The 23-engine gap. B19 rolled to the pad with only 10 of 33 Raptor 3s installed. This suggests SpaceX chose to do a partial test before completing the engine installation — a "test early, find problems early" approach consistent with SpaceX's iterative methodology. But it also means the full qualification test is weeks away minimum.

**What I expected but didn't find:** Any V3 performance data. The test was too short to generate meaningful thrust/efficiency numbers. Raptor 3's claimed improvements (higher thrust, fewer parts, better mass fraction) are unconfirmed by this test.

**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 successful development is the prerequisite for the cost reduction this claim depends on; the April launch target is the next gate
- [[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 with Raptor 3 is the vehicle that makes the cadence economics achievable; the April target is the demonstration milestone

**Extraction hints:**
No new extractable claims from this source — it's an update on a known trajectory. Primary value: milestone marker (first V3 static fire) and Pattern 2 continuity (April slip from original April 9 target).

**Context:** This is the same day as Blue Origin's Project Sunrise FCC filing (March 19). SpaceX executing its first V3 milestone while Blue Origin files for a 51,600-satellite constellation while NG-3 hasn't relaunched — the contrast in operational vs. strategic posture between the two companies is at its sharpest.

## 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: V3 milestone marker. First Raptor 3 static fire establishes the V3 paradigm is physically real. Important for tracking the Starship development trajectory and flight 12 April target.
EXTRACTION HINT: No new claims to extract. Update the existing Starship Flight 12 trajectory tracking — note the April slip and the remaining test sequence (33-engine static fire → ship testing → stack → launch).
