Study argues bigger launch vehicles may not always be better
Summary
A report released June 29 by The Aerospace Corp. suggests that super heavy lift (SHL) rockets, defined as those capable of placing at least 50 metric tons into low Earth orbit, may face diminishing returns beyond a certain size. While SHLs like SpaceX's Starship and Blue Origin's New Glenn 9x4 promise economies of scale, increased size could raise per-kilogram launch prices due to greater preparation and operational complexity. The study draws an analogy to the Airbus A380, a technical success but commercial disappointment due to high costs. Operational SHLs include SpaceX's Falcon Heavy, which has flown only 12 times since 2018, raising questions about market demand. The report identifies potential future markets like broadband constellations, orbital data centers, and space-based solar power, noting that only broadband constellations currently exist, suggesting market maturation will involve serving megaconstellations with regular launch cadences.
Key takeaway
For investors evaluating space launch ventures, recognize that super heavy lift rockets, despite their capacity, face significant market and operational risks. Your investment decisions should account for the potential for diminishing returns on scale, where increased size may not translate to lower per-kilogram costs or sufficient demand. Focus on ventures with clear market maturation paths, such as those serving megaconstellations, to mitigate the risk of underutilized assets like the Falcon Heavy.
Key insights
Super heavy lift rockets face diminishing returns, with excessive scale potentially increasing per-kilogram launch costs and complexity.
Principles

- Market factors often determine economic success.
- Low usage may presage low market demand.
In practice
- Consider market demand for SHL capacity.
- Evaluate operational complexity with scale.
- Target megaconstellations for initial SHL market.
