LOMPOC, California – United Launch Alliance ( ULA successfully completed its first flight in 2019. Today, the largest missile in the arsenal of the company in Colorado sent a classified cargo into space so the company finally managed to run through the delays saga
The ULA's Delta IV Heavy Rocket was chosen to send the rated payload NROL-71 in orbit (SLC-6) at 11:10 pm PST (14:10 EST), January 19, 2019. The flight was scheduled to begin earlier five minutes earlier, but was repulsed to allow the team to complete the final items before entering the terminal. This little correction marked the final slip of the often-delayed mission.
The NROL-71 was scheduled to begin on September 26, 7, 8, 18, 19, 20 and 30 (in 2018). On January 5, 2019, ULA said the start date was "under review."
"We understand this is a priority mission for the nation's military, and we take our commitment to security and mission security seriously," Gary said. Wenz, vice president of government and trade programs, said in a statement issued by ULA
The United Launch Alliance Delta Delta IV missile is located at Vandenberg's SLC-6 with payload NROL-71 for the National Intelligence Service. NROL-71 is the 28th ULA flight for the National Intelligence Service NRO ) and the 38th launch of the Delta IV rocket (the daily flight marks only the 11th use of the rocket in its "heavy" configuration). Delta IV first ascended on the sky on November 20, 2002.
The NRA is the US government agency responsible for designing, building, launching, and maintaining the US Navy of intelligence satellites. Established in 1961, the existence of NRAs has been a strictly guarded secret.
Until 1973, the very existence of NRAs was not public domain (and even then it was discovered by accident). It was declassified in September 1992. Now the NRA has its own Facebook page. NROL-71 is the 52nd known payload of the agency, which has been operating since 1996.
Mission logo for NROL-71. Because of the classified nature of the NROL-71, little is known about what was actually launched but is believed to be an electro-optical reconnaissance satellite operating from an elliptical polar orbit of about 160 Mission NROL -71 marked the first flight of the 233-meter Heavy version of the Vandenberg Delta IV rocket for more than five years. The vehicle consists of three common booster cores (CBCs), 16-foot (5-meter) payload diameter and Delta Cryogenic Second Stage. Each of the CBC is powered by RS-68A manufactured by Aerojet Rocketdyne . The second phase of the rocket is powered by a RL-10 engine
Each RS-68A engine provides approximately 702,000 pounds during the initial phase of the flight. After the play, the RL10B-2 released 24,750 kilograms of load to send the top stage of Delta IV Heavy to payload in orbit.
An old enemy seems to have been lifted shortly before the opening window was released today – a strong wind, as CEO and ULA President Tory Bruno noted in tweets before takeoff: "The wind rises upwards. Everyone thinks of calm thoughts. "When things got better, Bruno seemed more optimistic – something that paid off later in the day:" The board is green, the wind is tall but better. "90 seconds before the launch, the ULA commentator said something the startup team was waiting for a long time to hear: all the key elements were ready to support the fields. After the 90 seconds had elapsed, the flames flared from the base of the rocket to begin the flight.
After the rocket lifted off the pad, it began a short vertical climb before moving to the southern trajectory. Pacific ocean. He reached Mach 1 – the speed of the sound – about a minute and a half after takeoff.
About this point in the Delta IV Heavy mission, it burned about 2,000 kilograms of fuel per second. Four minutes, 10 seconds after it flew off, the two side mounted CBC exhausted their fuel and fell. Nearly two minutes later, the central core ended its mission and separated from the upper stage, which activated its lonely engine in about 5 minutes, 55 seconds after the burning, which had to take about 12 minutes and six seconds.
Since this is a classified mission, the ULA coverage of the start is completed by dividing the payload, which happens 6 minutes, 6 seconds after leaving the pad.
The next scheduled ULA flight is the launch of another Delta IV, mid-mid + (5.4). Its payload will be the 10th broadband satellite spacecraft SATCOM for the US Air Force. At the moment this mission will be launched on 13 March 2019 by the 37B Air Force Space of Cape Connaval in Florida.
