1. Background. Current threat countries are attempting to deny access to geographic areas by expanding threat capabilities against high-value airborne assets (HVAA) including mobility air force (MAF) refueling aircraft. This strategy, combined with existing MAF limitations, require F-22s to extend their combat radius using externally mounted fuel tanks that are low drag. Current F-22 fuel tanks and pylons are only useful in a ferry configuration and greatly decrease the capability of the F-22 in a combat scenario. Purpose-build pylons and fuel tanks will allow the F-22s to achieve higher airspeeds and fuel efficiency. All 27 ANG F-22s require this upgrade.
