Hi everyone, Despite the following being in the changelog: I am still experiencing issues with 5-inch/38 calibre guns, as fitted to the USS Samuel Chase and Essex-class. In the below tracks I have a single aircraft approaching the USS Samuel Chase from the starboard rear-quarter. Wind is calm, the ship is not in motion and I've set the weather to clear skies. In both cases the aircraft approaches from the same direction and remains in level flight, the only difference between the 2 tracks is the altitude the aircraft flies at. While the 3-inch/50 guns engage more-or-less as expected (when the aircraft briefly exits their engagement zone, they cease tracking and reset to their default positions instead of attempting to continue tracking the target - so far only the KS-19 appears to do this) in the 6kft track the 5-inch gun never engages, despite doing so in the 2kft track. 6000 ft should be more than within the capability of 5-inch gun (in-fact it outranges and has a higher ceiling than the 3-inch guns - compare this table (5"/38) with this table (3"/50)). With the Essex (which I've separately reported here) the guns track the target in both cases (the directors though do not), but only in the 2kft track do they actually engage. However, even so, they take a long time to commence firing (the Bofors 40 mm actually opening fire first) and they only get a single salvo off before resetting(-ish) and no 5-inch gun further attempts to engage the aircraft. In the 6kft track, they track the target, but never engage and simply reset, pretty much exactly mirroring this bug report for ground-based AAA - where so far only the KS-19 behaves as expected.

Hi everyone, The 5" mounts on the Essex appear to track aircraft but, in the majority of tests I've run, only actually engage below 2500 ft. In the tracks below I have a single Ju 88 A-4 at various altitudes that should be well within the engagement envelope of the guns. The only track where the guns engage reliably is the 2.4k ft track. The other thing is the range at which the guns start firing - according to the linked trajectory chart, the upper-limit of the range should be around 15000 yards (~13.7 km) for a target flying at 10,000 ft and around 16000-17000 yards (~14.5-15.5 km) maximum for a target at 2500 ft. In DCS however, the guns first start firing at around 1.5 nautical miles (or about 3000 yards or about 2.8 km) and only get a single salvo off (and even then, not all the mounts engage) before the carrier is overflown. Each gun should be able to fire at a rate of 15-22 rounds per minute (or 30-44 rounds per Mk 32 mount, as used on the Essex). Part of the range issue may be down to the directors (Mk 37 GFCS), whose radar ranges (for the Mark 12) are half of what they should be (they also are defined with the wrong frequency range). In Essex_Class_Carrier_1944.lua, the director's "distanceMax" is set to 25 km. The Mark 12 radar (the rectangular antenna on top of the director, mark 22 is the elliptical antenna beside it) should be able to track bomber-sized targets out to ~41 km [source] Suffice to say, these issues drastically limit the effectiveness of these guns.

Hi everyone, I've noticed that in some testing scenarios, large-calibre WWII AAA will only track targets without ever actually firing - instead at some point they stop tracking and reset (seen in the. Sometimes, guns will start engaging but will only fire a few rounds before ceasing. Adding the Kommandogerät 40 seems to resolve the issue for German Flak guns and the allied director resolves the issue for QF 3.7". However, the Kommandogerät 40 does not resolve the issue with either the 75 mm Type 88 AA gun, nor the 8 cm/40 3rd Year Type gun. However, the director shouldn't be required for guns to actually start firing (especially if they've detected and are tracking the target) - instead directors should make guns more accurate. The same issue also applies to ships (namely the Essex), which I've reported here, but have yet to make extensive tracks (I've seen it sometimes engage higher altitude targets, but my prevailing experience is that 5"-guns don't engage reliably, nor do the directors track targets reliably). The same issue does not occur with the KS-19, which is perfectly capable of engaging targets without its SON-9 director. 8.8cmFlak37_Engage-ish.trk 75mmType88_Engage-ish.trk 80mm3rdYearType_Engage-ish.trk KS-19_Engage.trk 8cm3rdYearType_NoEngage_3kft.trk 8cmFlak18_Engage_3kft_Kdo.trk 8cmFlak18_NoEngage_3kft.trk 75mmType88_NoEngage_3kft.trk KS-19_Engage_3kft.trk KS-19_Engage.trk
