What this is
About Rocket DB
A free, fast reference for every orbital launch vehicle ever flown. No sign-up, no advertising, no tracking beyond a page count.
The idea
Launch vehicle specifications are public, but they are scattered across encyclopedia articles, PDF user guides and operator marketing pages that each measure something slightly different. Comparing two rockets honestly means normalising all of it first.
Rocket DB does that once, at build time, and publishes the result: 453 vehicles with the same fields measured the same way, 92 operators, and 463 same-class head-to-head pages. Success rate with its flight counts, launches per year, and cost per kilogram to low Earth orbit are computed here and shown with their inputs.
How it is built
Every page is a static HTML file, generated ahead of time and served from the edge. There is no database behind this site, no API, and no JavaScript that fetches anything. The only script on the page is the theme toggle.
Data is refreshed on a rebuild, not on a request. See sources and method for where each number comes from and how the derived ones are calculated.
Thin pages
148 of the 453 vehicle pages cover rockets with fewer than three recorded flights. They exist for completeness and are marked noindex, because a page with three facts on it does not belong in a search result.
Who makes it
Rocket DB is a Planetary Industries company, built alongside Space Index, a directory of the companies in the space economy, and Spaceport DB, the same treatment for launch sites. Each links to the others where it helps.
Specifications from Launch Library 2 by The Space Devs, launch records from Space Index. Derived figures are computed here; see sources and method.
