The Philippine Air Force acquired 37 F-5A and F-5B from 1965 to 1998.
The F-5A/Bs were used by the 6th Tactical Fighter Squadron (Cobras) of the 5th Fighter Wing and the Blue Diamonds aerobatic team, replacing the F-86F Sabre previously used by 1965 and 1968 respectively.
The F-5s also underwent an upgrade which equipped it with surplus AN/APQ-153 radars with significant overhaul at the end of the 1970s to stretch their service lives another 15 years.

In 2005, the Philippines decommissioned its remaining F-5A/B fleet, including those received from Taiwan and South Korea.
