NF-5A on the Leviathan dev server

Yeah, the N variant of the ALE-40 also has a 10x3 flare variant according to some sources:

Interesting! Yeah, i guess the type of CM would play into how many are stored in the dispensers. E.g., a pair of AN/ALE-40 can hold 60 chaff, 60 small flares or 30 (36?) large flares.

This might be why its got 30 additional large flares, if there is no physical launcher on the model

This is blatant pay to win at 10.7. It has significantly more powerful engines that makes it approach the F-5E’s TWR. And a missile which is a significant upgrade over the 9J. It seems to have the gimbal limits and seeker FOV the 9L according to the HUD circles.

The AIM-9N is also known as the AIM-9J-1:

In 1973, Ford began production of an enhanced AIM-9J-1, later redesignated the AIM-9N. The November model employed a similar configuration to the Juliet, but the three main printed circuit boards were substantially redesigned to improve seeker performance. Close to 7,000 of this version were built. The Hercules-Aerojet Mk.17 rocket motor was retained. The Sidewinder Story / The Evolution of the AIM-9 Missile & https://www.designation-systems.net/dusrm/m-9.html

According to most sources it’s a minor improvement.

In-game they are identical

Both IR seeker heads, gimbal limits and FOV are visually and code-wise identical on the dev server

Please remember that everything you see on the dev server isn’t final and subject to change.

Go to a test flight and prep a missile. Observe the circles in the HUD. The outer ring is much bigger and the inner circle much smaller than on the 9J. You can also lock on to a target and launch at an extreme offset with the locked target on the outer edge of the big circle, which in the case of the 9J would be way out of the big circle. Of course it could be that the HUD circles are wrong on the 9J. In the case of the 9N they are identical or nearly identical to the 9G/H.

Please provide pictures, I have done the same test in my reply to you

According to my test on the dev server they are identical…

My bad then. The circles for the 9J seem to have been changed then. I haven’t noticed as I mainly play sim and can’t see the circles anyway.

Wait, a F-5E equivalent with similiar missiles at lower BR? Am i missing something?

It still has relatively significant worse engine performance compared to the F-5E and lacks a radar. (A radar, which I might remind you, that makes one of the best jet dogfighters in the game even more deadly, by having a ballistics computer for its guns.) It could come at 10.7 or 11.0 in ARB either way. Most BR’s on the dev server aren’t final, so we just don’t know at which BR it’ll come.

It also lacks Bullpups or mavericks.

The NF-5A sits between the US F-5A and the US F-5E in terms of weaponry and flight performance, but should be the most manouverable of all US F-5 models ever produced (by a slight margin when using flaps).

Its most comparable variant is the F-5C, but even that one doesn’t come that close.

I’m a student aircraft mechanic currently in training in the Netherlands. At our school, we have an NF-5B on display—the two-seat version of the NF-5A.

I’ve learned that the NF-5A has a flap system with three positions for the trailing edge flaps:

  • Up (retracted)
  • Down (fully extended — used during takeoff and landing)
  • Maneuver** (partially extended — used during combat or high-speed maneuvers)

The leading edge flaps have two positions:

  • Up (retracted)
  • Down** (extended — also used during takeoff and landing)

in game the NF-5 has four flap settings: Up, Takeoff, Landing, and Combat. However, this is not accurate. In reality, the “Takeoff” and “Landing” positions are the same (fully extended flaps), so the game’s flap options do not reflect the actual aircraft’s system.

the landing gear doors are not accurate compared to the real aircraft. The doors should be closed when the gear is down.

They only open when the gear handle is moved to the UP position — the doors open, the gear retracts, and then the doors close again.

The same happens in reverse when the gear is lowered: the doors open, the gear extends, and the doors close afterwards.

Should you have any proof of this and wish to tell Gaijin, consider making a bug report: Community Bug Reporting System

Gaijin devs most likely will never see this thread (which will also be closed down this week and will be unaccesible after that).

Well, I’m not too well versed in the NF-5, bar it being Canadair(and the mods Canada did to theirs), but iirc, one of the mods shared between the two should be a shorter takeoff compared to at least the F-5A.

I can’t get the dev server, so I’m here asking if that’s true(for both in-game and RL).

It does have more engine thrust and thus a shorter take-off length, if that’s what you’re asking. And that holds true in-game.

I see. It’s been a bit since I did anything with the CF-116s, so I don’t remember what gave it better take-off length, so I’ll have to assume that’s it.

Good to know.

done. thanks for the link. now hope they use the info I have given them

Your title mentions the NF-5B, which isn’t in the game, maybe consider specifying that these flap characteristics are also present on the NF-5A, which will come to the game.

Edit: for those interested to read the report:

https://community.gaijin.net/issues/p/warthunder/i/R8ixnibPmqzk

Closed with the following mention:

One report = one bug.
That is, you need to file one bug report on the flaps and another report on the landing gear doors. Then the report can be accepted.
Also, please attach the entire manual to the report.

I believe they also extended the frontal landing gear!

Yes, raised nose gear.

Changes on the dev server:

  • NF-5A: combat flap position polar blending increased from 0.2 to 0.3, which will mean combat flaps will now blend 30% into the full flaps polar rather than 20% previously
