Informal go-ahead was given for Korolev to start design work on the R-7. In parallel, Myasishchev OKB-23 and Lavochkin OKB-301 began design of intercontinental ramjet cruise missiles. References: 70 .

Bell flight 5. Pilot noted low-frequency elevator buzz at mach 0.93, did not proceed above this speed, pending buzz investigation. References: 49 , 97 .

Rocket performance test. Launched at 0847 local time. Reached 122.3 km.

Massive problems were encountered in the difficult test series - with poor-quality kerosene fuel, handling and leakage of the propellants, and reliable start of the engine. But the Red Army saw much more promise in the design than in Korolev's cumbersome liquid oxygen rockets.

Ministry of Armed Forces Decree 'On formation of UZKA of GAU' was issued. References: 474 .

Of the 8 rockets of the first production lot fired, 6 reached the target area.

Temperature, winds research. Launched at 0319 local time. Reached 107.8 km.

Density research. Launched at 1230 local time. Reached 111.1 km.

Bell flight 6. Buzz again noted at mach 0.93. Turbopump overspeeding caused pilot to terminate power and jettison remaining fuel. References: 49 , 97 .

First launching of a cluster of three Deacon rockets as a booster at NACA's Wallops Island. References: 17 .

Range achieved 270 km. First test launch of R-5. References: 283 , 344 .

Sky brightness, day airglow research. Launched at 0704 local time. Reached 114.3 km.

Sky brightness, day airglow research. Launched at 0847 local time. Reached 114.3 km.

Completion of first series of 8 R-5 flight tests. 2 achieved 270 km range, 5, 1200 km range, and one, 550 km range. References: 283 , 344 .

Jet Propulsion Laboratory completed development of the Corporal I, the first U.S. surface-to-surface ballistic missile, and continued with Corporal II development. Army Ordnance also asked JPL to study application of large-scale solid propellant rockets for use as surface-to-surface guided missiles. References: 17 .

The first production rocket was rolled out at Dnepropetrovsk (only six months after the first all-Dnepropetrovsk R-1). Following receipt of production missiles, divisions were deployed to Zhitomir; Kolomoaya; Medved, Novgorod oblast; Kamyshin, Volgograd oblast; Shyalya, Lithuania; Dzhambul, Kazakhstan; and Ordzhonikidze, in the Far East.

Ionosphere research. Launched at 1210 local time. Reached 135.2 km.
