Beriev VVA-14
This is the experimental Beriev VVA-14. And when we say experimental, we mean experimental…It was designed to be a vertical take-off, amphibious aircraft that could also operate over long-distances in anti-submarine defense roles. But there was only 2 ever built. Although it did accomplish flights – 107 flights with 103 flight hours – it never was used realistically as it was intended. Constant changes and retesting over the course of 1971-1975 culminated in the two VVA-14s retiring not long after.
