Alexeiev KM-1 CASP-A “Kaspian Monster” (experimental)

The project of this ground effect vehicle, or ekranoplane, began in 1963, giving rise to a prototype that made its maiden flight in 1966 and that was baptized as “Alexeyev KM”, although it is also known as “KM-1 Casp A” ekranoplane. The letters “K.M.” means “Korabl Maket”, (or experimental craft), but they have been popularly interpreted as “Kaspian Moster”, due to its appearance and size. The model did not pass the testing phase and was destroyed in an accident in 1980.
