The RD-180 is a powerful rocket engine developed by Aerojet Rocketdyne in collaboration with NPO Energomash, a Russian company. It is designed to be used in the Atlas V launch vehicle, providing significant thrust and efficiency for space missions. The engine operates on a unique staged combustion cycle, which enhances its performance and reliability. This engine uses a combination of kerosene and liquid oxygen as propellants, allowing it to produce about 180,000 pounds of thrust. The RD-180 has been instrumental in launching various payloads into orbit, including satellites and interplanetary missions, making it a key component of modern space exploration.
