BACKGROUND: The Air Force’s (AF) fleet of RMS must support the MMIII LGM-30G ICBM until the end of its operational life. However, the existing challenge of parts obsolescence poses a significant obstacle to providing seamless support. Additionally, a scarcity of spare parts, some entirely unobtainable, coupled with substantial engineering updates required by the Technical Data Package (TDP), further complicates the situation. Given these considerations, the AF aims to develop a new design, create a new TDP, and ultimately increase the RMS fleet. Procurement of 16 RMS4, including one to two RMS4 during the Engineering, Manufacturing, and Development (EMD) phase, will be required. During Production, the AF expects to procure the remaining 14 or 15 RMS4 for a total of 16. RMS DESCRIPTION: The RMS provides transportation of MMIII Stage 1, Stage 2, and Stage 3 solid boosters or select combinations of individual stages, herein referred to as the Boosters, loaded into the Stage 1, Stage 2, and Stage 3 Operational Rocket Motor Carriages. The RMS provides a transportation platform that limits excessive shock and vibration to the Boosters. It also provides a temperature-controlled environment designed to keep the Boosters within their required temperature range during transportation. The Environmental Control Unit provides the required temperature control by use of an on-board diesel fueled generator and a closed loop Heating Ventilation and Air Conditioning unit. /////////////////////////// RFI # 3 BELOW //////////////////// INFORMATION SOUGHT: Provide a detailed overview of your company's sub-contractor management plan.
