The RD-180 (Russian: Ракетный Двигатель-180 (РД-180), romanized: Raketnyy Dvigatel-180, lit. 'Rocket Engine-180') is a rocket engine that was designed and built in Russia. It features a dual combustion chamber , dual- nozzle design and is fueled by a RP-1 / LOX mixture.
The RD-180 uses only two combustion chambers instead of the four of the RD-170. The RD-180 used on the Atlas V replaced the three engines used on early Atlas rockets with a single engine and achieved significant payload and performance gains.
Under RD AMROSS, Pratt & Whitney is licensed to produce the RD-180 in the United States. Originally, production of the RD-180 in the US was scheduled to begin in 2008, but this did not happen. According to a 2005 GAO Assessment of Selected Major Weapon Programs, Pratt & Whitney planned to start building the engine in the United States with a ...

The oxygen-rich combustion technology developed for the NK-15 and refined in the NK-33 laid the groundwork for many of the most successful rocket engines in Soviet and Russian history. These include the RD-170, RD-180 and RD-191. While these engines share the oxygen-rich staged combustion cycle, they are not directly related to the NK-33.
The first bike manufactured by Yamaha was actually a copy of the German DKW RT 125; it had an air-cooled, two-stroke, single cylinder 125 cc engine [1] YC-1 (1956) was the second bike manufactured by Yamaha; it was a 175 cc single cylinder two-stroke. [1] YD-1 (1957) Yamaha began production of its first 250 cc, two-stroke twin, the YD1. [1]
