Atlas Missile: "Project Atlas Report 3rd Quarter 1957" Convair; ICBM Flight Test 6A Blowup

Jeff Quitney
Published on Nov 23, 2017

SM-65 Atlas second flight on 25 September 1957 ends early in the flight because of an engine shutdown after a failure in the fuel system. The Atlas was destroyed by the range safety officer at 63.6 seconds after liftoff.

The SM-65 Atlas was the first intercontinental ballistic missile (ICBM) developed and deployed by the United States. It was built for the U.S. Air Force by Convair Division of General Dynamics at the Kearny Mesa assembly plant north of San Diego, California. Atlas became operational as an ICBM in October 1959 and was used as the first stage for satellite launch vehicles for half a century. The Atlas missile's warhead was over 100 times more powerful than the bomb dropped over Nagasaki in 1945.

An initial development contract was given to Consolidated Vultee Aircraft (Convair) on 16 January 1951 for what was then called MX-1593, but at a relatively low priority. The 1953 testing of the first dry fuel H-bomb in the Soviet Union led to the project being dramatically accelerated. The initial design completed by Convair in 1953 was larger than the missile that eventually entered service. Estimated warhead weight was lowered from 8,000 lb (3,630 kg) to 3,000 lb (1,360 kg) based on highly favorable U.S. nuclear warhead tests in early 1954, and on 14 May 1954, the Atlas program was formally given the highest national priority. A major development and test contract were awarded to Convair on 14 January 1955 for a 10-foot (3 m) diameter missile to weigh about 250,000 lb (113,400 kg). Atlas development was tightly controlled by the Air Force's Western Development Division, WDD, later part of the Air Force Ballistic Missile Division... The first successful flight of a highly instrumented Atlas missile to full range occurred 28 November 1958. Atlas ICBMs were deployed operationally from 31 October 1959 to 12 April 1965.

On 18 December 1958, the launch of Atlas 10B sent the missile into orbit around the Earth (without the use of an upper stage) carrying the "SCORE" (Signal Communications by Orbiting Relay Equipment) communications payload. Atlas 10B/SCORE, at 8,750 lb (3,970 kg) was the heaviest man-made object then in orbit, the first voice relay satellite, and the first man-made object in space easily visible to the naked eye due to the large, mirror-polished stainless steel tank... Many retired Atlas ICBMs would be used as launch vehicles, most with an added spin-stabilized solid rocket motor upper stage for polar orbit military payloads. Even before its military use ended in 1965, Atlas had placed four Project Mercury astronauts in orbit and was becoming the foundation for a family of successful space launch vehicles, most notably Atlas Agena and Atlas Centaur.

Mergers led to the acquisition of the Atlas-Centaur line by Lockheed Martin which in turn became part of the United Launch Alliance. Today Lockheed Martin and ULA support a new Atlas rocket family based on the larger "Atlas V" which still uses the unique and highly efficient Centaur upper stage. Atlas V stage one is powered by a Russian RD-180 oxygen/kerosene engine and uses conventional aluminum isogrid tankage rather than the thin-wall, pressure-stabilized stainless steel tanks of the original Convair Atlas. Payload weights have increased along with launch vehicle weights over the years so the current Atlas V family serves many of the same type commercial, DoD, and planetary missions as earlier Atlas Centaurs.

Atlas Missile: "Project Atlas Report 2nd Quarter 1958" Convair; 7th & 8th Atlas ICBM Launches

Jeff Quitney
Published on Dec 24, 2017


SM-65 Atlas 7th flight on 5 April 1958 (Atlas 15A) experienced a turbopump failure at T+105 seconds. The 8th flight,  on 3 June 1958 (Atlas 16A), was the third successful flight of the Atlas missile, and the final flight of the "A" series Atlas.

The SM-65 Atlas was the first intercontinental ballistic missile (ICBM) developed and deployed by the United States.

Atlas 15A was the third Atlas to have been lost to a turbopump failure. There was a slight drop in pump speed at T+96 seconds and about ten seconds later, the pump shut down. The engines lost thrust and the Atlas fell into the ocean, remaining structurally intact until impact.

The Air Force had known about the pump problems for a while but were reluctant to have them replaced and slow down the test program. There were issues both with the lubricant oil foaming at high altitude and the bearings being knocked loose by the rotation of the pump. The flight of 15A convinced them to change the gearbox pressure and use a different oil that was less prone to foaming, but the bearing problem remained and it brought down two more flights (Thor 127 and Atlas 6B) before the pumps were replaced with an improved model.

At 14:45 in the video when the narrator says that 15A was the last flight with the 270,000 pound booster engines. This is actually incorrect, only the first four Atlas As used those and 15A had the 300,000 pound engines.

There were quite a few repeat Atlas failures due to rushed launch schedules. The engineers usually had an idea of what went wrong the first time it happened, but the Air Force couldn't be bothered to apply the necessary fixes. I'd mentioned before that they lost three Atlases in six months to hydraulic rise-off failures before having the heat shields redesigned.

There is a broadband hum in the vocal frequencies of this film which I cannot completely remove.
