US developing compact AIM-9X Sidewinder variant for internal bays

The US Navy and Air Force are developing an AIM-9X “Compact Variant” that repackages SIP IV upgrades into a smaller airframe optimized for internal carriage on advanced/stealth aircraft. The novelty is combining reduced size (higher internal magazine depth) with claimed improved kinematic performance and greater standoff range, potentially enabled by advanced propulsion work like highly loaded grain motors.
