The bill authorizes multiyear procurement contracts for specific aircraft and modifies inventory requirements for Air Force fighter aircraft.

  • 10 U.S.C. § 3501

    Subject to section 3501 of title 10, United States Code, except as provided in this section, the Secretary of Defense may enter into one or more multiyear contracts for the procurement of F-35A, F-35B, F-35C, and F-15EX aircraft.

    This allows the Secretary of Defense to enter into multiyear contracts specifically for the F-35 and F-15EX aircraft.

  • 10 U.S.C. § 3501

    Section 3501(i)(2) of such title shall not apply for purposes of this Act.

    This provision exempts the bill from a specific requirement in the existing law.

  • 10 U.S.C. § 9062

    (1) During the period beginning on October 1, 2017, and ending on October 1, 2026, the Secretary of the Air Force shall maintain a total aircraft inventory of fighter aircraft of not less than 1,800 aircraft, and a total primary mission aircraft inventory (combat-coded) of not less than 1,145 fighter aircraft. → (1) The Secretary of the Air Force shall-- (A) during the period beginning on October 1, 2026, and ending on October 1, 2035, maintain a total aircraft inventory of fighter aircraft of not less than 1,800 aircraft; and (B) maintain a total aircraft inventory of combat-coded fighter aircraft of-- (i) not less than 1,369 aircraft by December 31, 2030; and (ii) not less than 1,558 aircraft by December 31, 2035.

    This increases the specific inventory requirements for combat-coded fighter aircraft and extends the time frame for compliance.

  • 10 U.S.C. § 9062

    During the period beginning on October 1, 2017, and ending on October 1, 2026, the Secretary of the Air Force shall maintain a total aircraft inventory of fighter aircraft of not less than 1,800 aircraft. → (2) In this subsection: (A) The term `fighter aircraft' means an aircraft that-- (i) is designated by a mission design series prefix of F- or A-; (ii) is manned by one or two crewmembers; and (iii) executes single-role or multi-role missions, including air-to-air combat, air-to-ground attack, air interdiction, suppression or destruction of enemy air defenses, close air support, strike control and reconnaissance, combat search and rescue support, or airborne forward air control; and (ii) does not include collaborative combat aircraft.

    This clarifies the definition of fighter aircraft within the inventory requirements.

  • 10 U.S.C. § 9062

    The Secretary of the Air Force may increase the size of the F-15EX aircraft fleet from 129 to 329 F-15EX aircraft.

    This provides the Secretary of the Air Force with the authority to expand the F-15EX aircraft fleet significantly.
