The U.S. Air Force has launched a program to replace the aging LC-130H Polar Mission aircraft with a new LC-130J variant, focusing on structural upgrades and modifications for Arctic and Antarctic operations.

This initiative seeks to transition to a digital aircraft architecture and address long-term sustainment challenges. The Air Force plans to award contracts to Lockheed Martin and Sierra Nevada Corporation for the modernization effort, with a Request for Proposal expected around March 18, 2026.
