While the RD-170 had nozzles which swiveled on two axes, the RD-171's nozzles only swivel on one axis. [2] Models called the RD-172 and RD-173 were proposed, upgrades that would provide additional thrust, and the RD-173 proposal was finalized as the RD-171M upgrade in 2006.
On the next launch, also from pad 2, the first stage RD-171 engine failed five seconds after launch and the rocket fell back onto the launch pad from a height of about 70 metres (230 ft). The resulting explosion completely destroyed the launch pad, and was reported to have lifted a 1,000 tonne metal structure 20 metres into the air, and to have ...
The RD-180 engine, developed with Pratt & Whitney Rocketdyne through the RD AMROSS partnership, is a direct descendant of the RD-170 line and is used as the propulsion system for the first stage of Atlas V. [16] The most current engine listed on the NPO Energomash website is the single-chamber RD-191, developed for the Angara and Baikal launch ...
The Zenit-2 had its last flight in 2004; it has been superseded by the Zenit-2M, which incorporates enhancements made during the development of the Zenit-3SL. The Zenit-2 has a fairly low flight rate, as the Russian government usually avoids flying national-security payloads on Ukrainian rockets.
The combustion chambers of the RD-180 share a single turbopump unit, much like in its predecessor, the four-chambered RD-170. The RD-180 is fueled by an RP-1/LOX mixture and uses an extremely efficient, high-pressure staged combustion cycle. The engine runs with an oxidizer-to-fuel ratio of 2.72 and employs an oxygen-rich preburner, unlike ...
A diagram showing the layout of site 31. Note the big black box on the bottom left is МИК 40 (The hall where the rocket is assembled). Construction of Site 31/6 at Baikonur began in late 1958 as a second launch complex for the R-7 intercontinental ballistic missile (ICBM) at the cosmodrome.

Kh-25 being mounted on a Russian Su-24 at Khmeimim air base for use against Syrian insurgent targets. The Kh-25/Kh-25M (Russian: Х-25; NATO: AS-10 'Karen ') is a family of Soviet lightweight air-to-ground missiles with a modular range of guidance systems and a range of 10 km. [1] The anti-radiation variant (Kh-25MP) is known to NATO as the AS-12 'Kegler ' and has a range up to 40 km. [2 ...
