Caution: This market survey is being conducted to identify potential sources that may possess the specialized expertise, capabilities, and experience to meet the requirements to provide obsolescence resolution support for B-2 avionics systems. This effort requires a minimum of a SECRET/SAP level of security clearance. Contractors/Institutions responding to this market research are placed on notice that participation in this survey may not ensure participation in future solicitations or contract awards. The Government will not reimburse participants for any expenses associated with their participation in this survey. The Air Force is in search of prospective vendors for an engineering services effort regarding the B-2 Engine Start Control Unit (ESCU). The ESCU Line Replaceable Unit (LRU) contains five Circuit Card Assemblies (CCAs), Chassis Assembly, Interconnect CCA, and a Rear Cover Assembly. Its primary function is to simultaneously start four jet engines using either cross-bleed air, an Auxiliary Power Unit (APU), or an external air source to start the jet engines. Its secondary function includes operation and coupling/decoupling of the Airframe Mounted Accessory Drive (AMADs), limited control of the Air Turbine Starter Control Valves (ATSCVs), and limited control of the APU. The primary interface to external systems is a MIL-STD-1553B notice 2 communications bus. The unit is designed for a military avionics and nuclear environment. The ESCU is no longer in production and due to obsolescence issues, the capability to repair the LRU is declining. Subcomponents are obsolete and declining in spares, preventing purchase and replacement of throwaway parts. The purpose of this effort will be to resolve obsolescence and develop a sustainable solution for procurement. Potential vendors must be capable of performing the following tasks and meet the following requirements: Evaluation of BOM, all production/test equipment, and documentation per the Baseline Configuration Report for obsolescence and availability. Identify parts and materials that are presently obsolete and/or that are projected to be obsolete within six years. Based on the list of current and projected piece part obsolescence, the contractor shall identify and evaluate proposed alternatives for long term sustainment. LRU form, fit, and function shall be maintained. Meet all current B-2 ESCU P-Spec requirements. Address testing requirements for implementation of the proposed solution(s) into the LRU and the B-2 aircraft. Testing requirements may include, but are not limited to, bench test, component test, LRU-level test, subsystem-level test, system-level test, and environmental tests. The obsolescence solutions shall include, but are not limited to, obsolete support for test/support equipment, obsolete manufacturing methodologies, obsolete raw materials, obsolete manufacturers or vendors, obsolete government and industry standards and specifications, insufficient or missing technical data, and new laws and regulations. Determine what parts require further testing to assure feasibility of the proposed solutions. Develop and deliver an updated TDP. At this time, Northrop Grumman is the only known source with qualifications to execute this effort. Prior to release of technical data to prospective vendors, these vendors must first submit their capabilities and past performance to demonstrate the following: Define, plan, and perform nuclear effects testing of aircraft avionics components: Dose rate Total dose Neutron fluence Electromagnetic pulse Perform B-2 software integration testing Perform RDGT and other B-2 environmental testing (vibration, shock, and thermal) Support Electromagnetic Integration Compatibility (EMIC) Safety of Flight (SOF) testing Maintain an AS9110 (or equivalent) quality system Employ only individuals who can pass a Defense Investigative Service background check required for a SECRET clearance and maintain such clearance. Maintains a corporate cost accounting system that meets the requirements of DCMA and/or DCAA. Must not be owned (directly or indirectly) by a foreign company(ies) or individual(s) for the duration of any potential Government contract. As a small or large business, do you believe conditions exist for a small business set-aside in accordance with FAR 19.502-3(a) for any portion of the requirement described above? If yes, please indicate which portion of the requirement and the most appropriate NAICS code for each portion. Of the portion of work you identified as having the potential to be small business set-aside, are you most interested in performing as a prime contractor or subcontractor for the requirement described above? Please indicate whether you would qualify as a small or large business under the NAICS code you believe is most appropriate. If you are a small business, of the portion of work you identified as having the potential to be partially set-aside, are you capable of performing at least 50% of the work, in order to comply with FAR Clause 52.219-14, specifically 52.219-14(c)(1), “At least 50 percent of the cost of contract performance incurred for personnel shall be expended for employees of the concern.” If you are a small business interested in performing a portion of the requirement as a set- aside, provide a brief summary of your company’s experience and past performance within the past three years as a prime contractor as it relates to the magnitude of this anticipated requirement and/or the portion of the work you identified as having the potential to be partially set-aside. If a large business, relative to NAICS Code 541330, submit the reasonable expectation of subcontracting opportunities for small business concern(s) to provide materials, parts and/or services in support of your capabilities to meet the requirements of this effort.
