Difference between G-2 Galeb and NJ-21 Jastreb?

Does anyone know the difference between these two? Look the same to me, but there are different kits around.

Maybe you can see it like the Gnat... there is the two seat trainer version the RAF used, and the single seat fighter version India and Finland used in addition. 

Did not have Yugoslavia also some??

Yugoslavia bought two single-seat Gnats for evaluation (IIRC, they wanted to license produce them).

 

Special Hobby does a kit with the appropriate markings in 1/72.

 

As for the G-2/NJ-21, I am honestly not sure. The books I have say only 18 NJ-21's were ever built, and they went to a single regiment. I'm guessing (stress on guessing) it's the J-21 airframe, with some fuel removed and second seat thrown back in. IIRC, the J-21 airframe did have some differences to the G-2 as it was primarily a light strike aircraft (More hardpoints etc...). Again, this is of my somewhat lacking memory.

Short version; what Graham said. Long version:

 

Galeb:

Jastreb:

Thanks, but I am referring to the NJ-21 Jastreb two-seat trainer, not the J-21. It appears to be almost the same as the Galeb. However, the Jastreb is based on the Galeb. Then on the single-seat Jastreb there is in turn based the NJ-21 trainer (god knows why they would take this route?). 
 

The problem is that Lift Here Serbia does a kit of both, and I have no idea which one to pick, as even such excellent references as by HelionUK fail to mention the NJ-21 at all. On another forum someone mentioned the NJ-21 as distinguished by guns and pylons, but if so, that would mean that almost all Galebs online are aftually NJ-21s, as they do tend to feature guns...

After some more digging I found this info here. I didn't go through all pages: https://www.mycity-military.com/Avioni/G-2-Galeb-J-21-Jastreb_167.html

I assume the same applies to the NJ-21

 

Basic differences are
- three machine guns, Galeb has two
- six pylons for HVAR 5 ”rockets, Galeb has four
- larger tip tanks
- stronger construction
- stronger landig gear
- breaking parachute
- Viper 532 is more powerful than Viper 22-6
Jastreb is light attac aircraft, Galeb is a jet trainer.

Thanks, that is a good list, albeit I am not sure if it actually compares the two-seat Jastrebs with the Galeb, not just the regular J-21? Have you actually seen a picture with the three guns on a two-seater? Apparently calibre on NJ-21 should also be higher at 12.7mm. However, roles seem to have been somewhat interchangeable, if below really is a Galeb as I believe, because this one was used for ground attack:

It appears you are right, here one can clearly see the third gun on the NJ-21. Above link shows a G-2 Galeb in contrast. Seems like NJ-21 was indeed only in service in very limited numbers.

I found out only 18 Jastreb's were used by the Yugoslav AF, serials 23501-23518. Preserved/stored in the Belgrade museum are/were: 23502, 23505, 23506, 23507, 23512 and 23513. Type is listed as "TJ-1 (NJ-21 Jastreb)"

Nebbor,

there were few Jastreb two-seaters (NJ - nastavni jurisnik, TJ - trenazni jurisnik; both terms mean training attack aircraft) and plenty more single-seaters. Two-seater Jastrebs had 235XX serials and IJ-21 Jastrebs (IJ - izvidacki jurisnik - reconnaissannce attack aircraft) usualy had 234XX serials. Cheers

Jure
