About this IDV

The Boeing Company's Defense division was awarded a single-award indefinite delivery contract by the Naval Air Systems Command (NAVAIR) on April 24, 2020, with a ceiling value of $100.9 million and an ultimate completion date of September 30, 2028. This contract supports the F/A-18E/F Service Life Assessment Program (SLAP) and Service Life Extension Program (SLEP) Phase C Follow-On effort, with modifications incorporating changes to Contract Data Requirements Lists (CDRLs) and Statements of Work (SOW) for program management activities. The contract utilizes cost-plus-fixed-fee pricing and includes no small business set-aside designation, consistent with Boeing's status as a large, established defense contractor. Primary work is performed at Boeing facilities in St. Louis, Missouri and Berkeley, Missouri, with supporting locations in Patuxent River, Maryland and Arlington, Virginia. The contract provides NAVAIR with flexible procurement mechanisms to issue task orders for research, development, test, and evaluation (RDT&E) services across multiple fiscal years supporting the Navy's critical fighter aircraft sustainment and lifecycle extension initiatives.

The contract's task order portfolio demonstrates sustained demand for comprehensive engineering and technical services supporting the F/A-18 Super Hornet and EA-18G Growler programs. Delivered services encompass systems engineering analysis, finite element modeling, structural assessments, fatigue testing, low-observable enhancements, component design modifications, and service life extension evaluations. Task orders range from $179,000 to $8.86 million, addressing specific technical requirements such as balanced load condition development, damage tolerance allowables analysis, paint rebaselining for radar cross-section enhancement, and aircraft structural integrity assessments. Notable subcontractor Northrop Grumman Systems Corporation has provided major structural design and analysis support under several task orders. Through this IDIQ vehicle, NAVAIR efficiently manages workload fluctuations while maintaining continuity of engineering support essential for extending the operational lifespan and enhancing combat effectiveness of the Navy's tactical fighter aircraft fleet across multiple fleet modernization initiatives and engineering modification packages.
