Kosmos 233 (Russian: Космос 233 meaning Cosmos 233), known before launch as DS-P1-Yu No.15, was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1968 as part of the Dnepropetrovsk Sputnik programme.[1] It had a mass of 325 kilograms (717 lb).[1]

Kosmos 233 was launched from Site 133/1 at the Plesetsk Cosmodrome,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 18 July 1968 at 19:59:50 UTC, and resulted in Kosmos 233's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1968-061A.

Kosmos 233 was operated in an orbit with a perigee of 198 kilometres (123 mi), an apogee of 1,406 kilometres (874 mi), 81.9 degrees of inclination, and an orbital period of 100.91 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 7 February 1969.[4] It was the fifteenth of seventy nine DS-P1-Yu satellites to be launched,[1] and the fourteenth of seventy two to successfully reach orbit.[5]
