Notes
- The Be-2500 was a Beriev study for a 2,500-tonne amphibian that could cruise in ground effect or at altitude; it was never built.
- The file is a 123 × 156 × 29.12 m box from Wikipedia. GlobalSecurity publishes a smaller 115.5 × 125.51 m planform with the same height, so dimensions depend on the design iteration.
- Marked secondary.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
