RDRD--180 Background180 Background
• RD-180 Originally Pursued by General Dynamics in early 90’s for Atlas upgrade
• After General Dynamics merged with Martin Marietta which later became Lockheed Martin, engine studies solidified.
• In 1995, Lockheed Martin selected the joint venture team of NPO Energomash and Pratt & Whitney, (RD AMROSS) to provide the RD-180 for the Atlas IIAR (now Atlas III) and for their EELV LV designs.
• A three-phased development and certification program has now been completed which certifies the RD-180 for use on the Atlas III, Atlas V MLV, Atlas V HLV Strap-on LRBs and the Atlas V HLV Core (Common Core Booster) launch vehicle models.
• The Russian-American cooperation in this endeavor is unprecedented.
