The purpose of this legislation, known as the Airpower Acceleration Act of 2026, is to enable the U.S. Department of Defense to enter into long-term contracts for the purchase of F-35 and F-15EX aircraft. This aims to streamline the procurement process and ensure a steady supply of advanced military aircraft for the U.S. Air Force. Key provisions of the Act include the authorization for the Secretary of Defense to sign multiyear contracts for the procurement of various models of F-35 aircraft (F-35A, F-35B, and F-35C) as well as the F-15EX.
