Im grateful for the criticism, but i would like to specify and/or correct few things:
Thats the only thing it can do really. Would have great maneuverability and top speed, but armament completely useless against planes and only partly usefull against ground targets. I wouldnt see it being used much in air RB, just ground only, as it can do some damage there atleast.
L-39 can both take off and land on 480m and 600m, respectively, so War Thunders mid-tier airfield runways should be good enough (atleast the main ones). Even strategic bombers can land on them after all.
Also small fun fact: L-39 can even operate from grass runways:

Its able to carry 2x 100kg bombs, 2x 16x S-5K rocket pods and 2x R-3S missiles (which it probably wouldnt get on such low br ofcourse). Some sources even talk about ability to carry two PK-3 gunpods (with 3 PKM machinegun each), but i aint really sure about that because of lack of info
Honestly, i get your point. I myself also can see that this plane would be basically useless (which is why i put it so low in the first place), but at the same time i think removing it completely from the tree would also be a mistake, as it would create a preety significant BR gap and remove one of the most legendary training (and civilian) jet aircraft ever build from the tree (yes, there are also other variants of the L-39 in the tree, but those just arent anywhere as numerous and popular as the L-39C)
L-39ZO has 4 pylons instead of 2 on C, and can carry not only FAB-250, but also FAB-500 on pylons closer to the centre. That greatly improves its usefullness in both air and ground battles, but decreases its maneuverability by alot. It will again be completely unarmed, unless we give it the lackluster PK-3 gunpods or R-3S missiles. The BR of 6.3 seems kinda justified to me, or it should be at about 6.7/7.0 max, as Arado 234 B-2 with preety much the same armament (no guns, 1500kg of bombs) and comparable/slightly worse flight characteristics when fully loaded is also at 6.3.
Problem is, those IR missiles are R-3S - literally the worst IR missiles in-game, which can be very easily outmaneuvered by any pilot slightly aware of his surroundings. It also has a harder time locking onto non-jet airplanes with propellers, as they usually have way colder engines located on the front, decreasing the range of the missile drastically. L-39CM would thus bu nothing else than a classic L-39ZO with capability to ocasionally do boom-and-zoom attacks against unaware enemies or bombers.
Launch platform is also very important part of using FOX-3s effectively. Just look at the F-4 ICE. It can carry 4 AIM-120s (while ALCA would probably carry just 2), It has a better anti-air radar with better range (ALCAs radar is mainly anti-ground), its way faster, yet, the plane is overall shit compard to other FOX-3 aircraft. ALCA wouldnt be overpowered just because of having FOX-3s, either. I will ofcourse raise its BR in my tree accordingly with the new BR changes in the future, probably to 12.7 or 13.0.
That would create a terrible BR gap of 3.3 BRs, which isnt the greatest idea. I could see the L-39C and CA removed, with ZO staying exactly where it is and CM replacing CA in the premium line. Also, historical progression? Is that what i think it is? Because if yes, then we havent really had that in-game for a very long time (lets just look at majorit of Swedish tree)
That seems unnecessary. As ive already said, L-159 wont be anywhere close to being overpowered. Gaijin also doesnt even need to give it the AIM-120s, as it was never truly outfitted with them, but it can carry and use them after few small modifications (fitted for but not with is the official term)
That one is already in there, at rank IV, in the strike aircraft (middle) line. Same with scout L-29RS variant, which is in premium line. They are preety much like P-59A, just with way worse armament but better maneuverability. with just 8x 80mm (i think S-8) rockets and at best 2x 100kg bombs, it again is only useable as a low-flying ambush attacker, usefull for skilled pilots only.
Actually, your wrong. I mean about the guns obviously. The 7.92mm gunpods that the L-29 can use carry a whopping 90 rounds each, meaning 180 rounds in total. You will deplete all of your ammo in only 4.5 seconds, and with it being 7.92mm, it wont do much damage, either.
