Decree 'On establishment of NII-4' was issued. References: 474 .

Ionosphere research. Launched at 1148 local time. Reached 146.5 km.

Decree 'On adoption of the R-5M into armaments' was issued. Deployment of the missile began in 1956 in brigades of six launchers. Initially it took 30 hours to prepare the rocket for launch, but this was reduced to 5 to 6 hours after several years of service. References: 474 .

Robert O. Piland, Head of the STG Advanced Vehicle Team, and Stanley C. White of STG attended a meeting in Washington, D. C., sponsored by the NASA Office of Life Sciences Programs, to discuss radiation and its effect on manned space flight. Their research showed that it would be impracticable to shield against the inner Van Allen belt radiation but possible to shield against the outer belt with a moderate amount of protection.

Military-Industrial Commission (VPK) Decree 'On approval of the Almaz draft project' was issued. Chelomei's draft project showed the 11F71 Almaz station to consist of an 11F75 orbital block and an 11F74 VA landing apparatus (derived from the Apollo-type capsule he had designed for his LK-1 circumlunar spacecraft). Launch of the re-entry capsule with the cosmonauts would eliminate the need for the Soyuz 7K-TK ferry under development by Kozlov. References: 474 .

The draft project OIS 11F730 was issued jointly by TsKBEM and Filial 3 on 21 June 1968.
