The Pentagon’s Fiscal Year 2021 Unfunded Priorities List has put in a request to equip low-rate initial production (LRIP) Lot 15 F-35C fighters with the Sidekick internal weapons rack.
The Sidekick is a modification from Lockheed Martin to allow the A and C variants to carry up to six AIM-120 air-to-air missiles in its internal weapons bay.
