# Rocket Lab pivot to space systems reveals that vertical component integration may be more defensible than launch in the emerging space economy

SpaceX proved that vertical integration wins in launch — owning engines, structures, avionics, and recovery lets you iterate faster and price below anyone buying from suppliers. Rocket Lab is making the inverse bet: that vertical integration wins in everything around launch. Through six acquisitions between 2020 and 2025 — Sinclair Interplanetary (reaction wheels, star trackers), Planetary Systems Corporation (separation systems), SolAero Holdings (space-grade solar panels), Advanced Solutions Inc (flight software), Mynaric (laser optical communications), and Geost (electro-optical/infrared payloads) — Rocket Lab assembled the only component supply chain outside SpaceX spanning from raw subsystems to complete spacecraft buses. The Space Systems division now generates over 70% of quarterly revenue, with $436M in 2024 revenue tracking toward $725M in 2025.

The strategic logic crystallizes in Flatellite, a stackable mass-manufactured satellite platform incorporating all of Rocket Lab's acquired components. A customer using Rocket Lab components, on a Rocket Lab bus, launched on a Rocket Lab rocket, operated with Rocket Lab ground software (InterMission), faces switching costs that compound at every layer. The $1.3B in Space Development Agency contracts (18 satellites for Tranche 2 at $515M, 18 missile-tracking satellites for Tranche 3 at $816M) validates this as a prime contractor play, not just a parts business.

The deeper insight is about market structure. The launch market has strong winner-take-most dynamics because launch is operationally indivisible and SpaceX's Starlink-funded flywheel creates structural cost advantages. But satellite manufacturing, component supply, and constellation operations layers are more contestable because they decompose into specialized capabilities where focused investment achieves defensible positions. The question the space economy hasn't answered: does value accrue primarily to whoever moves mass cheapest, or to whoever controls the most layers above launch?

## Challenges

Rocket Lab's $38.6B market cap at ~48x forward revenue prices in the thesis. The January 2026 Neutron tank rupture added schedule risk, though the stock reaction was muted because the market increasingly values the systems business over launch. If launch fully commoditizes (Starship at sub-$100/kg), the value-above-launch thesis strengthens. But if Neutron fails entirely, Rocket Lab loses captive launch demand that pulls through component sales.

Relevant Notes:
- [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]] — SpaceX built integration from launch down; Rocket Lab builds from components up
- [[launch cost reduction is the keystone variable that unlocks every downstream space industry at specific price thresholds]] — if launch commoditizes completely, value shifts to what rides on rockets — exactly where Rocket Lab is positioning
- [[value in industry transitions accrues to bottleneck positions in the emerging architecture not to pioneers or to the largest incumbents]] — Rocket Lab's component monopoly positions are the bet
