Phase 1 consisted of a study of the German A4b and A9 boost-glide missiles; Phase 2 consisted of study of replacing the rocket engines of the design with supersonic ramjets in order to extend the range; Phase 3 would determine the size and type of the booster needed to boost the reengined A9 to ramjet ignition speed. At this time North American has a staff of 43 working at its Technical Research Laboratory in Los Angeles, including 12 PhD's and 18 ME's.

Launched 11:16 local time. Reached 109.7 km. Carried pressure, ionosphere, sky brightness, biological, photo experiments for Air Research and Development Command. First of a series of V-2 firings known as Blossom Project, tested ejection of canister and its recovery by parachute, containing fruit flies and various types of seeds exposed to cosmic rays.

Studies for a copy of the Me-163B rocket fighter were already undertaken by OKB MiG in 1944. Post-war Soviet technical teams discovered the more advanced Ju-248 (Me-263) design and the decision was made that MiG would copy this design. The first airframe, Zh-1, began glider tests in December 1946. The Zh-2, rocket-powered with a dual thrust engine first flew in March 1947. The I-270 was abandoned after the Zh-2 was written off after a hard landing in spring 1947.

North American's Kinetic Double-Integrating Accelerometer (KDIA) design allowed an inertial platform to also measure distance traveled. This breakthrough would allow long-distance unpiloted high-accuracy navigation. North American also discovered that the A9 swept-wing design was unstable at transonic speeds. The company selected an aft-wing with forward canard layout for the MX-770.

Stalin is fascinated with Saenger's design for an intercontinental rocket bomber. He calls a meeting in the Kremlin, and orders Serov to locate Saenger and bring him to Russia. However Saenger is in Paris, and attempts to kidnap him are thwarted by the French secret police.

Douglas pilot Eugene F. May flew the number one Skystreak for the first time on April 14, 1947, at Muroc Army Airfield (later renamed Edwards Air Force Base) in Calif. The goals of the program were to investigate the operation of a straight-wing configuration in the lower third of the transonic speed range (which extended from roughly 0.7 to 1.3 times the speed of sound).

Launched 14:22 local time. Reached 142.7 km. Carried pressure, temperature (Signal Corps Engineering Lab, University of Michigan) experiments for General Electric. The warhead section was replaced with an instrumented full-scale replica of the cylindrical GE A-4 ramjet duct planned for the Hermes B ramjet missile.

The G-1 was Groettrup's first design after the German engineering team had been moved to Russia. The first group of 234 specialists was given the task of designing a 600 km range rocket (the G-1/R-10). Work had begun on this already in Germany but the initial challenge in Russia was that the technical documentation was somehow still 'in transit' from the Zentralwerke. The other obstacle was Russian manufacturing technology, which was equivalent to that of Germany at the beginning of the 1930's. The Germans worked at two locations, NII-88 (Korolev OKB) and Gorodmlya Island to complete the design of the G-1. Other groups of Germans worked at Factory 88 (R-1 production) and Factory 456 (Glushko OKB / engine production).

Hermes B-1 impacts a graveyard 18.5 km south of Juarez, Mexico on its first test flight. This and the out-of-range V-2 impact on 15 May resulted in new safety measures at WSPG. 'We were the first German unit to not only infiltrate the United States, but to attack Mexico from US soil'. This vehicle was deeply classified at the time. Hermes experiments were conducted with modified V-2 rockets to test the configuration of a ramjet propulsion system. Four Hermes B-1 rockets were flown from Complex 33, none of which were noted in the contemporary records.

The concentration on fhe 800-km range missile was to be abandoned. Prototype missiles were now to be produced in three phases. Phase I would produce a missile with a range of 280 to 800 km; Phase II, one of 800 to 2400 km; and Phase III one of 2400 to 8000 km.

Contract with Convair for the MX-774 "Upper Air Test Vehicle," predecessor of the Atlas ICBM, was cancelled by the AAF. However the service approves Convair use of unexpended MX-774 funds to launch the MX-774 test vehicles already built. The decision made to move Vultee operations to San Diego.

The selected design was 14.2 m x 1.62 m, 18,400 kg gross weight, empty weight 1,960 kg, 32,000 kgf thrust, LOX/alochol propellants, 20 atm pressure thrust chamber, integral tanks, turbine driven by exhaust gases, control section in back, radio beam guidance, 900 km range, accuracy - 25% in a 1.0 km box.

Operation Sandy - German V-2 rocket launched from U.S. aircraft carrrier Midway in Atlantic tests, exploding prematurely after a 10 km flight. This had been preceded by Operation Pushover - the deliberate explosion of a fully tanked V-2 on a dummy shipdeck at White Sands to determine its effect on shipboard launching. Launched from Atlantic Ocean Launch Site 10 "several hundred mi SE Bermuda" - Latitude: 27.00 N, Longitude:60.00 W.

The Air Force was now a separate service from the US Army. The agreement was made that the Air Force would only handle missiles with ranges over 1600 km. So the range requirement for the MX-770 (later the Navaho) was increased to 1600 km, while carrying a 1350-kg payload with an 800 m CEP, and it became an Air Force missile. The 800-km MX-771 (later Matador) became an Army missile. The MX-775 Snark already had an intercontinental range requirement, and became an Air Force missile.

North American began construction of a wind tunnel at its new rocket test facility in the Santa Susanna mountains, in the northwest San Fernando Valley, north of Los Angeles. The Technical Research Center was renamed the Astrophysics Laboratory. The aerodynamics and control systems work on the MX-770 had already been fed back into North American's swept-wing F-86 Sabre fighter design.

Launched 12:15 local time. Reached 156.5 km. Carried Solar radiation (Naval Research Lab); pressure, composition (SCEL) experiments for General Electric. General Electric engineers obtained the first carefully instrumented heat-transfer data from supersonic flight when this V-2 attained 1520 m/s.
