I remember either Jaap Terweij or Maarten Houtman did an article on Albatross in our Dutch magazine Spaceview. Might even have been before 83 but I am at sea at the moment so cant access my archieve and the actual Spaceview magazine but I guess Jaap will know.

Rostislav Alexeyev built the latter part of his engineering career on ground effect, which is the demonstrable fact that a wing generates more lift and experiences less drag when it's in close proximity to the ground than it does while high in the air. In general aircraft don't take advantage of it when cruising because of the increased risk—the ground is right there—in the event of something going wrong, but Alexeyev was an expert on hydrofoil design and felt that the problem was sufficiently mitigated by flying over water to be worth attacking. Between the Khrushchev era and his death in 1980 he built his largest ekranoplan ("screen plane"), the so-called "Kaspian Monster" (KM: korabl maket, "test vehicle") which met a watery fate in an accident not long after Alexeyev's demise.

If you're the sort of person who's interested in Soviet crewed spaceflight you're probably the sort of person who finds Russian ekranoplans and hydrofoils interesting too, but you may be wondering where the connection is between the two that would cause the latter to show up on a  blog devoted to the former. The intersection of this particular Venn diagram is the Albatros, outlined in a remarkable letter to the British Interplanetary Society's Spaceflight magazine, published in 1983.

Long-time readers will recall that the Soviet space program was in disarray for much of the early 1970s, with 1974 being the year of crisis. Vasili Mishin was replaced by Valentin Glushko<https://falsesteps.wordpress.com/2012/09/26/chief-designers-1-valentin-glushko/> as the man in charge, and officials higher than him forced a change in focus from Moon missions to a space shuttle and space stations. For a period of time everything was in the air, and as was endemic to the Soviet space effort various other empire builders tried to get themselves a piece of the pie.

The design bureau of OKB-51 lurked on the edges of the Russian space program right from the very beginning, but never managed to convert its expertise in high-performance aircraft into any concrete projects. In 1974 they teamed with Alexeyev's Central Hydrofoil Design Bureau to make a claim on the shuttle project, as at the time it was not yet settled that the Soviets would emulate the American Space Shuttle closely to produce Energia<https://falsesteps.wordpress.com/2012/09/12/energiavulkan-the-last-big-rocket/>/Buran (consider, for example, Glushko's MTKVP<https://falsesteps.wordpress.com/2012/10/06/mtkvp-glushkos-opening-gambit/>, which also dates to the same time). Their proposal was named Albatros, and it's, so long as the source, space historian and writer Neville Kidger, got his Cold War information right, the only triphibious spaceplane ever proposed, requiring both water and air to get into orbit and land for its return
