What tech development is needed to make this things work against jets again?
Make it shoot faster and aim autonomously
>>65610785Increase muzzle velocity to >5km/s
>>65610785AI
>>65610785>Asking why a manually aimed HMG doesn't shoot down jets in a world of CIWS and missilesPerhaps because it never worked nor was it ever intended to, it shot down origami paper biplanes real good though.
>>65611099The first monoplanes were not much better than biplanes. The Swordfish and Devastator have similar flight performance.
>>65610785HMGs in .50 are still capable in AA roles against many modern aircrafts... as long as is in a 1 or 2 thousand yards range.A rusty mig-24 or a basic configuration F15 can cover much more distance than a M2, even using autocannons instead of guided missiles.In theory, you can manufacture spicier ammo (sabot, Raufoss...) combined with heavier barrels and aiming platforms/optics. But at the end of the day, a manpad is better in terms of cost/efectiveness.Or you can go the Navy way and research scifi stuff like lasers and gauss cannons.
>>65611355>>65611099In what world does that look like an HMG rather than clearly being a 20mm oerlikon
>>65610785you can literally see the step-by-step development of AA with each refit >.50cals and 1.1in guns at the start of the war>neither dont have enough range and power, so they swapped for 20mm cannons (OPs pic) for short range and 40mm cannons for medium range>planes get too fast to track with the mk1 eyeball, so they add gun-directors to mechanically calculate lead and drop to the 40mm, 20mm is pretty useless at this point but it takes up little space and can be manned by non-vital crew>planes get too fast to reliably hit directly, even with radar-directors, so they add proximity fuzes> 3in guns, which can take VT fuzes and have even more range, become the new standard, 40mm and 20mm guns are now only marginal but are usually kept in places as last-ditch guns for targets that get too close for the 3in gun>proximity fuzes eventually miniaturized for 40mm cannons, doesnt make them good enough to shoot down jets but its still an upgrade for older ships that still have them>20mm cannon is given multiple barrels to spew enough bullets to compensate for lack of payload, given radar direction to improve accuracy over humans, and given automatic traverse to slew fast enough to hit supersonic targets at close range
>>65612278>>planes get too fast to track with the mk1 eyeballyou can just say eyeball or eye, you don't need to add mk1 like a faggot redditor trying to be clever
>>65612285>reddit boogeymanrent free
>>65612285That's not from Reddit li'l bro.
Tech that stops guided munitions forcing aircraft into dumb bomb range.
>>65612415the 20mm was already at the absolute edge of its capabilities against mid-war prop planes with dumb bombsa modern jet with iron bombs would still easily get an accurate drop from outside the combat envelope of a 20mm cannon, especially one that still relies on a web-sight as its only targetting aid
>>65612418It's fucked then.
>>65612422well, its already been mentioned that the 20mm stopped being used for precisely this reason the solution was to just remove the man entirely and make it shoot 1000x faster
>>65612278>you can literally see the step-by-step development of AA with each refitYes.To add to this overview,>so they swapped for 20mm cannons (OPs pic) for short range and 40mm cannons for medium rangeThis was 2 steps, 20mm first, then 40mm>but it takes up little space and can be manned by non-vital crewRequires few crew, and does not require electricity to operate>3in guns, which can take VT fuzes and have even more range, become the new standard3in guns were already in use interwar and were actually the main long-range AA armament for large ships>40mm and 20mm guns are now only marginal but are usually kept in places asMutually-assured deterrent; a bomber pilot could be frightened off by their presence because they virtually guaranteed death at close range unless he was suicidalAnd, well, it turned out there was in fact a breed of suicidal pilot in the Pacific...>>65612285Oh, son...
>>65612705>3in guns were already in use interwar and were actually the main long-range AA armament for large shipsthe gun itself dates back to WW1, but its use as the main long-range AA gun wouldnt occur until after proximity fuzes were available the north carolina was built exclusively with 1.1in and .50cal guns, before being refitted with the 40mm and 20mm cannons while the iowa-class had those guns equipped from the startit was the colorado-class that had the 3in gun as an AA gun, but they didnt have any proximity fuzes and were only equipped as a substitute for the 1.1in because they didnt have anythe reason why battleships didnt need to replace their 40mm guns with 3in guns is because they already had a significant battery of 5in guns that could take proximity fuzes
>>65612715>its use as the main long-range AA gun wouldnt occur until after proximity fuzes were availableThe 1910 Town class cruisers carried a 3" AA gun and this set the standard worldwide, though of course some navies adopted other calibres and the RN introduced other calibres too, but they hovered around the 3" mark:The Germans settled on the 88mmThe Italians carried 4"ersThe French carried 75mms ie roughly 3" before moving up to 100mmsThe Japanese carried 80mms (one is tempted to say they wanted a π-calibre gun...)In the US Navy, the Omaha CLs carried 3" AA guns and were even upgunned with more in the early 30s, and the Standard Battleships carried 3" AA guns.
>>65612715>but they didnt have any proximity fuzesDoesn't matter>and were only equipped as a substitute for the 1.1inNo, the 1.1" and similar weapons were close-in weapons and widely regarded as having insufficient range to be the mainstay AA battery for large warships(Destroyers generally had no room to fit purpose-built AA long-range guns, but of course they would eventually get the DP battery)>the iowa-class had those guns equipped from the startThe later American warships dropped the 3" AAs because with the introduction in service of the 5" DP gun>the reason why battleships didnt need to replace their 40mm guns with 3in guns is because they already had a significant battery of 5in guns thatwere capable of DP operation, a design factor even before prox fuzes were inventedAfter the war radar-guided prox-fuzed 3" guns were actually considered for major warship AA armament, they were seen as the ideal balance between performance and weight. (The 5" was too heavy for practical automatic power-loading.) US carriers, destroyers and I think cruisers carried them. But their time was relatively brief as jet bombers and antiship missiles quickly grew faster and more accurate.
>>65612742>But their time was relatively briefnot so fast
>>65612809Smartarse =DI knew that was coming. I should have added a disclaimer, "in the context of>its use as the main long-range AAarmament for major warships"
>>65612370Drachinifel is reddit culture
Programmable fragmented airburst munition, EO/RADAR guidance, stabilization25mm and 20mm revolver guns will have a comeback for some "reasons"
>>656127423" vt-shelled guns replaced 40mm bofors on cruisers after the war.
>>65613770>he thinks some redditor came up with the termThis is an adults only website
>>65613823That segment at 25 seconds should not have been included for a sales pitch.
>>65610785Nothing actually, some things just die out
>>6561662920mm cannons are still used for close-in defensethey are just radar guided, fire far faster, and can operate both autonomously or slaved to the main FCS so they can function even when the ship is damaged
