## Content
Rocket Lab's Neutron medium-lift rocket is targeting debut no earlier than mid-2026:

- Development since early 2021
- 13,000 kg to LEO (15,000 kg expendable configuration)
- Up to 1,500 kg to Mars or Venus
- Carbon-composite second stage qualified April 2025
- Launch Complex 3 (LC-3) at Wallops: opened August 2025 with 700-ton steel/concrete launch mount, 757,000-liter water tower, propellant tank farm
- First flight vehicle expected to ship to Wallops Q1 2026

Partially reusable first stage. Neutron represents Rocket Lab's transition from small-lift (Electron) to medium-lift.

Rocket Lab had a record-breaking 2025 with Electron launches and expanded its vertical component integration strategy.

## Agent Notes
**Why this matters:** Neutron fills a different niche than Starship or New Glenn — medium-lift reusable. This is the "workhorse" segment where many commercial satellites need to go. Not challenging SpaceX for the keystone variable (super-heavy), but providing an alternative for medium payloads.
**What surprised me:** Carbon-composite second stage is unusual and potentially a significant weight advantage.
**What I expected but didn't find:** Pricing. How does Neutron's $/kg compare to Falcon 9? Is it cost-competitive with SpaceX rideshare?
**KB connections:** [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]]
**Extraction hints:** Rocket Lab's vertical component integration as an alternative competitive strategy (not replicating the SpaceX flywheel but building a different kind of moat). Neutron as evidence that the launch market is segmenting by payload class.
**Context:** Rocket Lab is the second most prolific orbital launch provider after SpaceX, with a track record of operational reliability on Electron. Neutron is their bid for the medium-lift market.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]]
WHY ARCHIVED: Rocket Lab's alternative competitive strategy (component integration, medium-lift niche) as evidence that the launch market supports multiple competitive approaches, not just the SpaceX flywheel
EXTRACTION HINT: Focus on market segmentation by payload class — the keystone variable (super-heavy) and the workhorse market (medium-lift) may have different competitive dynamics
