10 things you didn’t know about the F‑5

Every fact links to the page on this site where it is sourced.

01

It flew before the Beatles had a hit.

The first F-5 took to the air in July 1959, according to the National Museum of the U.S. Air Force. That design was still flying as a front-line training opponent more than 60 years later.

02

The Tiger II was more than a new name.

The F-5E got J85-21 engines with about 20 percent more thrust, roughly 9 percent more wing area, maneuvering flaps and more internal fuel. NASA's history lists all of them.

03

It got radar late.

The early Freedom Fighter had no fire-control radar. The F-5E added an Emerson AN/APQ-153 radar as part of an integrated fire-control system.

04

Switzerland bought 110 of them.

The Swiss Air Force bought 110 F-5Es from the U.S. Air Force in the 1970s and flew them lightly, which later made them valuable to the U.S. Navy.

05

Then the U.S. bought them back, twice.

In a reverse Foreign Military Sales program, the Navy bought 44 former Swiss jets over six years for $50 million. Later it went back for 22 more.

06

They came home in cargo planes.

Each of the first Swiss F-5Es was flown from Emmen, Switzerland, to St. Augustine, Florida, inside a Navy C-130T.

Two jets went in, one came out.

NAVAIR described each F-5N as an old Navy F-5E combined with a newer Swiss airframe. One jet arrived at the plant each month for a five-month rebuild.

08

The Navy built three FrankenTigers.

These two-seat F-5Fs used the cockpit and tail sections of old Navy F-5Fs bolted to former Swiss center sections. The first one flew on November 25, 2008.

09

An F-5E helped make sonic booms quieter.

NASA flew an F-5E with a reshaped nose to test whether shaping could soften a sonic boom. That is why its nose should never be used as a standard F-5E clue.

10

You can tell most variants apart by counting seats.

One cockpit points to an F-5A, F-5E or F-5N, and two to an F-5B or F-5F. It is the first thing to check when you identify an F-5, but not the last.
