The Department of Defense, specifically the Department of the Air Force, is seeking contractors to modernize and upgrade the LC-130H Polar Mission aircraft to the LC-130J variant. The objective is to find qualified firms capable of delivering a fully modified and integrated LC-130J that meets the requirements for polar missions, as the existing LC-130H fleet is being phased out. This modernization effort is crucial for maintaining operational capabilities in polar environments, and the government may consider a sole-source contract with Lockheed Martin Corp. Interested contractors must submit their responses, including a Contractor Capability Survey, by December 22, 2025, to Amber Mathe at amber.mathe@us.af.mil or Hannah Tuck at hannah.tuck.1@us.af.mil, as the information gathered will be used solely for market research purposes.
