Northrop F-5 Freedom Fighter / Tiger II

Also known as
  • F-5
  • F-5A/B Freedom Fighter
  • F-5E/F Tiger II

The Northrop F-5 Freedom Fighter / Tiger II is a lightweight supersonic fighter family developed by Northrop for export customers, low operating cost, and easy support. The later F-5E/F Tiger II and F-5N/F adversary aircraft kept the design relevant through radar, structural, avionics, and training-role upgrades, while combat use spans Vietnam, Iran, Yemen, North Africa, and other source-limited air-war records.

Role in Conflicts

Side
United States and South Vietnam

USAF F-5C Skoshi Tiger aircraft were combat-tested in Vietnam from 1965 to 1967, then surviving aircraft were transferred to the South Vietnamese air force for continued F-5 operations.

Side
North Yemen

North Yemeni F-5E Tiger IIs saw combat during the 1994 civil war, including reported air-to-air engagements with South Yemeni aircraft and helicopters.

Side
Somali government and aligned forces
Role in conflict
Legacy fighter fleet

Somalia operated a small F-5 fleet that is tied to the country's air arm and broader civil-war-era combat aviation record.

F-5 Family Notes

The F-5 family is best read as a set of export fighter, combat-test, reconnaissance, and adversary-training branches rather than a single fixed configuration.
