An Army task force was formed to develop a plan for establishing a manned lunar outpost by the quickest practical means. The effort was called Project Horizon. The first phase of the project was to make a limited feasibility study, with estimated time and costs. The task force worked under the direction of Maj. Gen. John B. Medaris of the Army Ordnance Missile Command and in full collaboration with the von Braun team. The report was completed on June 8. References: 16 .
Primary objectives of the drops were to study further the spacecraft suitability and flotation capability after water impact. Six drops were made, but later (April 24-28, 1961) the tests were extended for two additional drops to monitor hard-surface landing effects. In the water phase of the program, spacecraft components under particular scrutiny were the lower pressure bulkhead and its capability to withstanding heat shield recontact without impairing flotation capability. Helicopters were used to make the drops. References: 483 .
Aside from the baseline Soyuz-B circumlunar mission, the draft project also proposed the Soyuz-P space interceptor and the Soyuz-R command-reconnaissance spacecraft. The military projects Soyuz-P and Soyuz-R were ‘subcontracted’ to OKB-1 Filial Number 3, based in Samara. The Soyuz B circumlunar version did not receive the same level of financial support.
Weight growth of the MOL station forced the Air Force to consider upgrading of the Titan booster. Stretching of the booster core or use of 156 inch solid rocket motors was considered. The Air Force also dithered as to whether to compete the Titan booster contract. Eight months were spent making the decision, and at the end of it all the first manned MOL flight was delayed to 1970 and the projected total cost increased from $ 1.5 billion to $ 2.2 billion.

NASA announced it would use the Apollo-Saturn 204 launch vehicle to launch the first lunar module on its unmanned test flight. Since the 204 vehicle was prepared and was not damaged in the Apollo 204 fire in January, it would be used instead of the originally planned AS-206. References: 16 .
