Northrop F-5 Tiger "Freedom Fighter"
Northrop T-38 Talon
Northrop F-20 Tigershark

In 1954, engineers at Northrop's started studies on a cheap supersonic fighter susceptible of being used by an important number of allied countries. The N-156F was born and three prototypes were ordered by the Department of Defence in May 1958. The first machine made her maiden flight on July 30, 1959 while the third exemplar would never be finished.

With its "coke bottle shape" fuselage designed in accordance with the transonic area rule, its light weight and sophisticated lift devices, the F-5 quickly demonstrated exceptional manoeuvrability in all flight phases.

It's the T-38 Talon training version that was first developed to replace the ageing Lockheed T-33. The Talon was used by NASA as an assistance and training aircraft.

In July 1963, the first F-5A finally flies for the first time. Named "Freedom Fighter", the plane is primarily designed as a ground attack fighter. The US Military Assistance Program (MAP) will permit exportation of the F-5 to several countries like Iran, Turkey, Greece, Philippines and South Korea. A "Skoshi Tiger" ("Small Tiger") version will even be evaluated in Vietnam, but this project will not have any follow up, except for the nickname "Tiger" that will be adopted from this time.

In November 1970, Northrop wins the IIFA (Improved International Fighter Aircraft) contract for development of an air superiority fighter with the F-5E Tiger II. The new J85-GE-21 engine is after burner equipped and the Tiger II flies for the first time in March 1969. It will be operational from April 1973 and will be used by the NAS Miramar "Top Gun" school as aggressor aircraft, due to its many resemblances with the MiG-21.

Always willing to offer allied forces an inexpensive fighter well adapted to their needs, Northrop developed the F-5G, much less sophisticated, compared to fighters like the General Dynamics F-16. But when the Reagan administration decided on exportation of the F-16, chances of the F-5G were doomed on foreign markets. It was a true catastrophe for 2000 personnel that lost their jobs at Northrop factories. Renamed F-20 Tigershark, the first of three prototypes had flown for the first time on August 30, 1982. Unfortunately, two of those prototypes crashed in flight demonstrations. Able of flying at Mach 2, thanks to a very reliable single G-E F404 jet engine, the F-20 was equipped with sophisticated avionics, like a General Electric multi-mode radar and a Teledyne mission computer.

It's on the airframe of an F-5 (fuselage and nose wheel) that the Grumman X-29 inverted swept wing prototype was built.

Used by more than 50 air forces throughout the world, 2622 F-5 were built in different configurations:

  • F-5A Tiger : Ground attack version.
  • RF-5A : Recon version of the F-5A .
  • F-5B Tiger : Two seat version of the F-5A.
  • F-5C Tiger : U.S.A.F. version of the F-5A.
  • F-5D Tiger : U.S.A.F. version of the F-5B.
  • F-5E Tiger II : Air superiority version.
  • RF-5E Tigereye : Recon version of the F-5E.
  • F-5F Tiger II : Two seat version of the F-5E.
  • F-20 TigerShark (Initially F-5G) : Single engine (F404-GE-100) version. It will never be produced.
  • SR-5A/SR-5B/SRF-5A : Casa (Spain) licence built versions.
  • CF-5A/CF-5D/NF-5A/NF-5B : Canadair (Canada) licence built versions.
  • T-38 Talon : Trainer version.

    FAQ

    I don't see my comments any more!

    Please note that each page has it's own comment entry. So, if you enter a comment i.e. on the B-747, you will only see it on that related page.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    But they remain accessible, for example by scrolling the mouse wheel, or with your finger (on the menu) on a smartphone or tablet.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    General

    Fluid website

    Browser compatibility

    The site is not optimized, or even designed to run on older browsers or those deliberately deviating from standards. You will most probably encounter display issues with Internet Explorer. In this case, it is strongly recommended installing a modern (and free!) browser that's respecting the standards, like Firefox, Opera, Chrome or Safari.

    Cookies and Javascript

    This site uses cookies and JavaScript to function properly. Please ensure that your browser is configured accordingly. Neither of these technologies, or other means shall in no case be used on the Site for the retention or disclosure of personal information about its Visitors. See the "Legal" page for more on this subject.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
