Building Angara

Despite the strategic importance of the Angara project, it remained on the drawing board for most of the 1990s. The active development of the rocket and of its launch pad in Plesetsk started picking up pace only by the mid-2000s. However, even with improved funding, numerous technical and organizational problems plagued the project.

Development

After expanding the Angara project into a whole family of boosters in 1997, it likely became even more difficult to fund. During the next two years, GKNPTs Khrunichev worked on a full-scale mockup of the Angara 1.1 vehicle, which was displayed at the Paris Air and Space Show in Le Bourget in June 1999. The Technical Project for the Angara was completed a year later, opening the door to the production of the engineering documentation and blueprints.

According to the design of the Angara family, its payload could vary from two tons all the way to 23 tons, depending on the number of booster "modules" attached to the identical core stage. The "heaviest" Angara would replace the Proton rocket, while the Angara-3 could replace Zenit.

Despite many proclamations about the strategic importance of the project, it was hardly moving during the first five years of 2000s. In an interview with the ITAR-TASS news agency in August 2014, the head of GKNPTs Khrunichev Vladimir Nesterov said that from 1994 to 2005, the project had received no more than four percent of the required funding. Around a half of this money came in 2004 and 2005. Part of the funding came from GKNPTs Khrunichev's profits earned in commercial missions of Proton rockets.

During a meeting in November 2001, officials from the Ministry of Defense, Space Forces, Rosaviakosmos and GKNPTs Khrunichev made a new commitment to development of the launch infrastructure of the Angara in Plesetsk beginning in 2002. At the time, the first launch of the Angara-1 rocket from a "bare-bone" launch pad in Plesetsk was planned for 2003.

However funding was not available even for the minimal infrastructure in Plesetsk. Moreover, by 2004, the Russian Ministry of Defense apparently informed developers that it will have no use for the light-weight Angara-1 rocket in the foreseeable future, endorsing the heavy Angara-5 instead.

However only on Nov. 17, 2004, the Russian government approved a new launch site development program aimed to make Russia independent from Kazakhstan in space launches. According to the new plan, the priority would be given to the deployment of the Angara-5 rocket in Plesetsk -- a much more expensive proposition. (597) The official history of GKNPTs Khrunichev published in 2006 had promised the first Angara launch in 2008. The book also said that the company had been in process of building Angara's rocket modules intended for ground testing. (355) In reality, at the internal meeting in March 2006, the project officials estimated that the first Angara could realistically fly no earlier than 2011. When President Vladimir Putin visited Plesetsk on Dec. 14, 2006, he told journalists that it would be possible "to accelerate" the development of the Angara, advancing its first flight from 2012 to 2011. (597)

Moving to Omsk

The manufacturing of the Angara's early hardware at Khrunichev in Moscow was centered at Building No. 128. The final assembly was conducted at Building No. 22. In the meantime, GKNPTs Khrunichev delegated a serial production of Angara's first stage, or URM-1, to PO Polyot in the city of Omsk, which had previously built now discontinued Kosmos-3M rockets.

First test vehicles

The manufacturing of Angara launchers for first two missions had been underway at GKNPTs Khrunichev, the company's press-release said in March 2011. Khrunichev also announced that all development documentation for the flight control system had been completed at NPTs AP. The autonomous tests of components for the flight control system had been completed, while integrated and software testing had been conducted at a test stand, Khrunichev announced.

In the meantime, the testing of the RD-191 engine was continuing, with a total burn time reaching 17,000 seconds. The 14D23 engine, which served as a prototype for the RD-0124 engine on the Angara's second stage, logged more than 50,000 seconds in live-firing tests. (By that time, an essentially same engine flew four times on the third stage of the Soyuz-2-1b rocket.)

According to Khrunichev, practically all autonomous tests of Angara's components had been completed, including propellant tanks, dry compartments, main engines, flight control and telemetry systems. The company estimated their readiness at 99 percent.

Companies located in Voronezh, Perm and Omsk were expected to manufacture various components for the RD-191 engine, with the final assembly taking place at NPO Energomash in Khimki near Moscow. In 2011, there were also reports that the serial production of the RD-191 engine was planned at the Proton-PM company in the city of Perm. At the time, Proton-PM planned to produce no less than 60 percent of these engines by 2015 with first deliveries scheduled in 2012. The company also planned to introduce a new factory at the town of Novye Lyady by 2017, which would eventually take over the entire production of RD-191. (471) On May 23, 2011, an interagency commission declared the RD-191 engine operational, clearing it for use on the Angara rocket.

Before 2012, NPO Energomash did supply six RD-191 engines for the first mission of the Angara-1 and Angara-5 rockets and planned to deliver five more units during that year. Around the same time, GKNPTs Khrunichev and NPO Energomash also signed a 5-billion-ruble contract for the production of additional 21 engines during 2013-2015. A total of seven engines would be produced annually during this period, enabling one launch of the Angara-5 rocket and two missions of Angara-1. (563)

According to industry sources, a total price tag for the Angara project reached around $5 billion in 2012.

First test launch

In 2008, the first launch of the Angara rocket was promised at the end of 2010 or at the beginning of 2011. During 2009, preparations for the first test mission cleared a major hurdle with three successful test firings of the first stage booster, which also performed well during the first ill-fated launch of the South-Korean KSLV rocket. However around the same time, various unofficial reports said that a delay of the first Angara launch to 2012 would be necessary. In the middle of 2010, the first launch was delayed from 2012 to 2013.

Serial production in Omsk

The second round of upgrades was conducted at Angara's production plant in Omsk during 2015 at a reported price tug of six billion rubles (in addition to seven billion spent on the first round from 2009 to 2014). By that time, the first launch of the Angara-5 had already taken place and the serial production of the rocket was becoming a reality. Imported state-of-the-art machines for manufacturing of tanks as large as four meters in diameter were installed at Building No. 12, where special foundations had to be built first.

At the end of June 2015, a big delegation of space officials led by Dmitry Rogozin visited Omsk on their way to Vostochny.

2009 Jan. 19: NPO Energomash announced that the last test version of the RD-191 rocket engine was going through final firings after a total of 97 tests with an accumulated firing time of 20,789. The maximum firing time accumulated by a single engine reached 3,635 seconds in 12 tests. At the time, the manufacturer had already supplied an engine for the firing tests of the entire rocket stage and promised to supply first six flight-ready engines in 2010 for actual test launches of the Angara rocket.

2009 April 29: During "cold tests" KhSI-1 at NIIKhimmash facility in Peresvet, around 100 tons of liquid oxygen were loaded onboard the URM-1 stage of the Angara rocket.

2009 June 18: During KhSI-2 test at NIIKhimmash fuel and oxidizer were loaded into the URM-1 stage. Pneumatic and hydraulic systems tested.

2009 July 30, 17:15 Moscow Time: Angara's URM-1 rocket booster (Article I1A1S) test fired for the first time at the IS-102 test stand in Peresvet near Moscow at NITs RKP test facility (former NIIKhimmash). During the test known as OSI-1, the engine was burning for 232 seconds, essentially imitating the entire process of the first stage operation during the orbital launch. According to preliminary information, no major problems arose during the firing. At the time, the second firing was expected at the beginning of September 2009. The total of three firings of the same booster were originally expected.

2009 Aug. 19: Roskosmos and GKNPTs Khrunichev signed an agreement for the development of the manufacturing base at the Proton-PM company in the city of Perm for the mass production of the RD-191 engine.

2009 Aug. 25: A South-Korean Naro-1 (KSLV-1) launch vehicle, fails to deliver the STSAT-2 satellite from the Naro space center, South Korea, due to an upper stage failure, despite initial reports about a successful launch. However Russian-built first stage, which was identical to the Angara's URM-1 booster, reportedly performs well. The mission was delayed from mid-August 2009.

2009 Oct. 1: Angara's URM-1 rocket booster test fired for the second time at NITs RKP test facility (former NIIKhimmash) in Peresvet near Moscow. During the test known as OSI-2, the engine was burning for 203.4 seconds under maximum throttle possible, imitating the flight profile of the Angara-5 vehicle.

2009 November: The URM-2 upper stage module of the Angara rocket is rolled out to the IS-102 test stand in Peresvet near Moscow at NITs RKP test facility (former NIIKhimmash) for fitting checks. The thermal conditioning and fire safety systems were also tested.

2009 Nov. 26: Angara's URM-1 rocket booster test fired at NITs RKP test facility (former NIIKhimmash) in Peresvet near Moscow. Designated OSI-3, it was the third and final test of Angara's first stage. The test cleared the way to preparations for live firings of the URM-2 upper stage of the Angara rocket.

2010 March 4: The Angara's second stage (known as URM-2 module) rolled out from the assembly building to the IS-102 test stand at NITs RKP in Peresvet in preparation for "cold" tests of the propulsion system.

2010 June 10: A South-Korean KSLV-1 launch vehicle fails some 136-137 seconds after the launch during the powered flight of the Khrunichev-built first stage. A simultaneous loss of telemetry and a bright flash of light are recorded at the time of a mishap. The failure could have major implications for a long-delayed maiden mission of the Angara rocket.

2010 June 17: "Cold" tests of the URM-2 module, checking fueling and pneumatic systems of the rocket stage, initiated at NITs RKP test facility. Live firing of the stage were scheduled for the fall of 2010.

2010 Aug. 3: Official Russian media quote a source at NPO Energomash as saying that the RD-191 engine "burned down" during one of multiple tests. The statement implied that the engine was destroyed in a some kind of planned endurance test, not as a result of a catastrophic failure.

2010 Nov. 18: The URM-2 upper stage module of the Angara rocket fired its RD-0124A-I propulsion system for the first time at the IS-102 static test stand in NITs RKP test facility in Peresvet near Moscow. The 399-second firing simulated the performance of the engine during expected launches of the Angara rocket. It was shut down after one of the propellant components was completely used up.

2011 March 30: A meeting of the Chief Designer Council on the Angara system is held at GKNPTs Khrunichev, Moscow.

2011 May 23: NPO Energomash published a press-release declaring the development of the RD-191 engine completed. By that time, the engine went through 120 firings with a total burn time of 26,747.4 seconds, including three ground tests on the full-scale URM-1 stage and two flights on the Korean KSLV rocket.

2012 Jan. 20: NPO Energomash conducted a certification test firing of the RD-191 No. D016 engine featuring a first combustion chamber manufactured at Voronezh Mechanical Plant, VMZ. A total of 18 firings were to be conducted using three copies of the engine for six tests each. NPO Energomash did not provide any details on the results of the tests, however, the announcement about the test was preceded by unofficial sources reported serious quality problems on combustion chambers produced at VMZ.

2012 April: Zvezdochka shipyard in Severodvinsk completes factory tests of the first of two mobile erectors, which was designed for transportation and the installation of the Angara-1 rocket from horizontal into vertical position on its launch pad in Plesetsk.
