Israel Fouga/ Tzukit

Thanks Andy! Do you have a source for that info?
I try to collect as many images as possible from the net to confirm my serial lists.

No, they did not routinely change serials for security reasons, that is a myth. Sometimes the first digit was changed, but the last two digits remained constant. This first digit usually changed when an aircraft was upgraded. For example, CH-53 c/n 65127 started as 414, then became 714, then 914 as various upgrades were performed.
I can think of hardly any cases when the actual serial was changed. Some examples:
AH-64As when they were converted to AH-64D got new serials
F-16C 236 became 140 (special serial for 140 Sqn)
F-16C 535 became 101 (special serial for 101 Sqn)
The three RF-4E(S) changed serials to 492, 498, 499 (special serials for recce aircraft)

It is true to say that the Fougas received new serials when they were converted to Tzukits, but this would have had nothing to do with security. They were simply numbered from 01 to 86! Here’s what I have.
The 5__ serials were from Israeli assembled kits (except for 560 ex France). 6__ serials are ex German.
Tzukit c/n is 0__ (last two digits of serial). C/n shown is Fouga c/n, or German c/n (first 62 German aircraft also have Fouga c/n)

yup!

Didn’t they change the serials form time to time for security reasons

I know. They had several examples borrowed from Israel. Most were returned as they couldn’t maintain them. I’ve been researching Fougas for 20 years and written a book about them (see my signature). Just never been able to put together a decent Israeli serial list. Very hard to find IAF info.

Uganda Air Force had some in 1966, maybe you can research them. Idi Amin would not fit in the cockpit 😉 Isreali’s trained the pilots. cya
