Project of Aerocosmic system 'Spiral' started in 1965 under supervision of leading designer G.E.Lozino-Lozinsky in Design Bureau of A.I.Mikoyan. Project included two wide-fuselage aircraft, linked into aerodynamically clean horizontal takeoff/landing
system for multiple use. Orbital airplane supposed to take of from "mother ship" at altitude 28-30km.

Two scaled (1:3 and 1:2) unmanned prototypes were designated 'Bor' and were flown during rocked launches to test heat screen.

There were also three "Analog 105" aircraft, built to evaluate subsonic handling during landing ("105.11", see picture), supersonic ("105.12") and hypersonic ("105.13") behavior.

Unlike "Space Shuttle"/"Buran", EPOS employed flexible "scale plate armor" made of many steel plates, hanged on special ceramic bearings. This solution allowed to keep all plates in place in wide temperature range, and is much cheaper "Space
Shuttle"/"Buran" quartz based skin.
