Anti-air definitly depends on what kind of air. Lightly-armoured annoyingly-manoeuvrable craft like the flying squirrel are a different kind of game than a metal airship. The rest also depends, but to a lesser degree


Anti-armour probably currently HESH, unless a spall-liner is present. HEAT may also penetrate, but doesn't do as much damage, and suffers against spaced armour (but works against shields). Plain AP/sabot shells will obviously also work. APHE can work, but you'll likely need loads of gunpowder and relatively long shells to pierce more than one metre of metal. Neither AP nor APHE will work against shields, until the shields get updated.

Anti-air prob airburst ammo at that calibre. Flak, HE, or high-spread frag. As said, that depends alot on what the "air" target is though.

Anti-shield: HEAT will hardly suffer against shields. HE/flak will work if the shields are close enough. Frag will spawn on the other side of the shield, if triggered by an inertial fuse, but the fragments will not pass layered shields.
It might be worth adding a dedicated anti-shield turret, fireing those anti-shield EMP rounds.
Shields are also planned to be changed - when changed, a high AP value compared to the shield strength will give shells a higher chance to pass shields. Might allow sabots and AP-shells to destroy shielded vehicles.

There isn't really a universal anymore. Before this last update, frag shells with a 1° cone was really the all-rounder, as they could penetrate shields, pierce armor, and we're quick enough to take down aircraft. But with this last patch, the narrower the cone, the less damage each fragment does, making these shells not worth it as compared to other shells.

For anti-shields, I would suggest a HEAT shell. These do absolute havoc on the target, and with an Inertial fuse are able to pass through shielding. If you want a high AP shot, set the penetration ratio high (this is found I'm the warhead module). For heavy internal damage, set the penetration factor low. I also set the special factor of the HE modules to full, just because it increases the effectiveness of the HEAT shell.

For anti-armor, either a HEAT or HESH shell are optimal. This is simply because that these shells almost completely ignore armor, instead doing major damage to internal structures. I mentioned BEAT prior, so I will discuss HESH shells. These are great for taking down large craft, even if they are several times larger than you. When a HESH shell hits a vehicle, it sends a shockwave through the armor, causing the inner layer of armor to fragment or "spall". On vehicles with nothing but heavy armor (full metal or full heavy armor) this is quite effective.

Finally, for anti-air, there are a few routes you can take. Going with the more conventional, you can use flak shells with timed fuses. This insures that the shell will detonate, although this is not very well suited for combating vehicles that fly at different altitudes. Flak is good against shielded aircraft that rely on components such as wings, ailerons, and rudders to stay airborne. It is also good against light to medium armored craft. Should you want to use modern AA rather than AAA, a simple AP shell with either a visible tracer or Base Bleeder will work well against, unshielded aircraft.

yeppers. My missile feish has taken care of aircraft. For tanks, a combo of HEAT (for sheilds) and HESH (for when the sheilds are down) are most effective. Pure HE also seems effective for some reason.

HE is just a damage dealer. It has no special gimmicks or needs some arbitrary AP value. It's just good, consistent damage. Most of my ships use HE, just cause it is reliable against all types of armor.
