A German market research firm, Capitol Momentum, has published an extensive report on the financial and technical health of Germany's three most prominent small launch companies—HyImpulse Technologies, Isar Aerospace, and Rocket Factory Augsburg.

The report ( which requires an email address to download) provides a trove of data about the companies, which are all attempting to bring orbital rockets online within the next 12 to 24 months.

One red flag for me is that both HyImpulse and Rocket Factory Augsburg have business cases built around 50 commercial launches a year, which seems completely unrealizable, both from a demand standpoint as well as the exceptional technical capability needed to reach such a cadence.

Exactly what this filing means for the company's future will probably not become clear until Virgin Orbit releases financial details about its fourth-quarter earnings for 2022, and this may not happen until late March.

But there are a few things in the filing that raise concerns about the financial solvency of the US-based small-launch company, Ars reports.
