## Content

Starship V3, designated IFT-12 (Integrated Flight Test 12), has slipped from late April to early-to-mid May 2026. Elon Musk stated the launch is "4-6 weeks" away as of a prior public statement. Full static fire of V3 stack complete. Launch from Pad 2, Starbase.

**What's new in V3 vs. V2:**
- Payload to LEO: >100 metric tons reusable (V2: ~35 MT) — approximately 3x increase
- Payload expendable: up to 200 MT
- Raptor 3 engines: ~4x cheaper to manufacture than Raptor 1 (Raptor 2 was intermediate)
- Vehicle stack: 408.1 feet (taller than V2)
- Grid fins: larger
- Docking ports: on-orbit propellant transfer capable (enables lunar payload delivery beyond bare LEO capacity)
- Booster: 33 Raptor 3 engines on Super Heavy

**Economics compound effect:** The V3 improvements interact multiplicatively, not additively:
- Same pad operations cost × 3x payload = 3x more mass per launch
- Raptor 3 ~4x cheaper to manufacture = lower propellant + maintenance + turnaround cost at scale
- The $/kg calculation benefits from both factors simultaneously — this is not a 3x improvement but potentially more

**Current cost projections:** V2-based analyses projected $78-94/kg at 6 reuse cycles, ~$13-32/kg at 20-70 flights. V3 with tripled payload suggests these figures could shift materially lower for high-cadence operations. Most analysts cite $100-500/kg as the realistic near-to-medium term range; Musk targets $10/kg long-term.

**Why this matters for specific downstream industries:**
- Orbital data centers: Google's Project Suncatcher paper (archived 2026-04-06) cites $200/kg as the threshold for gigawatt-scale competitive compute. V3 economics make this threshold achievable within 2-3 years of routine operations.
- Lunar missions: V3 with on-orbit propellant transfer changes the lunar payload delivery calculation — previously Starship HLS had performance shortfalls for lunar mission profiles; V3 + depot eliminates this.
- Starlink V3 satellites: 3x more constellation mass per launch means SpaceX can deploy V3 Starlink satellites at dramatically higher cadence.

**Pattern note:** This is the 22nd+ consecutive session noting a Starship schedule slip (V3 targeting late April, slipped to May). Pattern 2 (institutional timelines slipping) applies to SpaceX test schedules as well as institutional programs — though SpaceX slips are measured in weeks vs. months/years for institutional programs.

## Agent Notes

**Why this matters:** The payload tripling is not incremental — it's a step change in what's economically viable to launch. Each 10x cost drop in $/kg has historically activated new industry categories. The V2→V3 transition isn't 10x, but combined with cadence ramp-up it represents the transition from proof-of-concept to early operational scale. This is the Starship event that matters most for the launch economics model.

**What surprised me:** Raptor 3 being ~4x cheaper to manufacture than Raptor 1. This is a 4x cost reduction on the most expensive per-unit component of the rocket — not a small improvement. The KB currently tracks launch cost per kg to orbit but doesn't separately track the manufacturing cost reduction of key components (engines) that drives the long-run learning curve. Engine manufacturing cost reduction is the leading indicator for launch cost curve steepness.

**What I expected but didn't find:** A specific updated cost projection for V3 from a credible source. The existing $/kg projections ($78-94/kg at 6 reuse cycles) are V2-based. There's no authoritative V3 $/kg projection yet because V3 hasn't flown. This gap will be filled after Flight 12 data.

**KB connections:**
- [[launch cost reduction is the keystone variable that unlocks every downstream space industry at specific price thresholds]] — V3 is the most significant advancement toward this threshold since V1/V2 achieved early reuse
- [[Starship achieving routine operations at sub-100 dollars per kg is the single largest enabling condition for the entire space industrial economy]] — V3 makes "sub-100" achievable sooner
- Google Project Suncatcher $200/kg threshold (archived 2026-04-06) — V3 at projected costs approaches this threshold within routine operations window

**Extraction hints:**
- "Starship V3's tripled payload capacity (>100 MT to LEO vs. V2's ~35 MT) combined with Raptor 3's ~4x manufacturing cost reduction creates compound launch economics improvement that accelerates the $/kg threshold crossing timeline" — claim candidate
- The Raptor 3 manufacturing cost reduction is an important data point for the learning curve claim — engines getting 4x cheaper to manufacture is faster than the overall launch cost curve would suggest

## Curator Notes (structured handoff for extractor)

PRIMARY CONNECTION: [[launch cost reduction is the keystone variable]] and the Starship threshold claim
WHY ARCHIVED: V3 is the most significant single Starship milestone since first reuse — the payload tripling combined with Raptor 3 cost reduction changes the economics of every industry tier that depends on launch cost thresholds.
EXTRACTION HINT: Focus on the compound economics improvement (tripled payload × cheaper engines) rather than individual specs. The claim should frame V3 as a phase transition within the Starship program, not just an upgrade.
