I don't have info if Rockwell is involved in this variant, but I do know it's different from the old AHRLAC.

The old one had these stats:

- 20mm cannon

- 6x pylons, 800kg total

- 2200km range

- 10 hours loiter

Pic 1 is new Bronco II version artists impression, pic 2 is old AHRLAC version.

In the OA it's going to go up against AT-6 and Tucano. Compared to them the Bronco II has less payload, but a better internal gun compared to their 12.7mm peashooters, plus 2-3x the range and endurance.

The one they mounted on the original Ahrlac is a naval cannon, because it's all the company had. As such it's very heavy for what it shoots because the peoeple who engineered it didn't care about weight. It weighs 332kg (gun+feed system) and fires 750rpm.

Compare it with proper aircraft cannons, which are built for lightness. M197 and M39 both fire around 1500rpm and are under 150kg, so it might be feasible to put two of each on the Ahrlac to get 3000rpm. The Vulcan the bong mentioned is 252kg gun+feed, and fires 6000rpm.

>people who dont understand what cannons on attack aircraft are for

Oh for fucks sake… Canons on aircraft aren't for penetrating even light armor. They exist to kill everything that isn't armor, which is 99% of targets on the ground. The pylons are for the armor, the cannon is for everything else, capische? If the cannon was for armor, attack aircraft wouldn't even have pylons.

Also if we just had missiles, it could take out eight AFVs the enemy had…. but what the fuck would it do for the fifty trucks or 250 troops? When CAS is called in, its usually to save a team of guys on the ground who are surrounded by enemies. Usually the team of guys on the ground aren't surrounded by main battle tanks.

The cannons are:

1. Dirt cheap

2. Unjammable

3. Directed

4. Cluster munitions dispenser

As such even a low velocity M230 chain gun can do the job, because its job isn't to stupidly penetrate a surface, it's to carry a payload to the target.

Also why 20mm on Bronco II is oodles superior to 12.7mm on Tucano and AT-6… the 20mm can actually pack an explosive load.

>effective against infantry

The 20x139mm HEI round has a ~10g filler with no frag liner. It's no more deadly to soft targets than regular old API, and with such a small volume of fire that simply isn't happening. A single seven-tube Hydra pod or Mk.82 would be several times more effective than the Ahrlac's entire magazine of 20mm.

>muh missiles

Most APCs could be mission-killed if not destroyed outright with half a dozen 20mm rounds. Assuming 30% accuracy, that's around fifteen APCs you just disabled without even touching your very limited external payload, and for a tiny fraction of the cost of a single Hellfire.

1500rpm, 10g, that means it dumps 750g of explosives in one three second burst. And this is more evenly spread than a single 750g bomb, so it's more effective pound for pound, which is why you're wrong on the bomb. You're right on the rockets though, they're also a type of directed cluster munitions dispenser, if a bit more innacurate and a bit less "directed"…

In fact depending on some design choices - the perfect attack aircraft weapon would be something like Balkan AGS caseless mini-rocket grenades stacked in the same way as Metalstorm in long tubes axially to the attack aircrafts body. No one is doing this because it's still very much an untested system with a lot of drawbacks…

>APCs

My bad, I'm mentally classifying APCs under light armor, since some of them can be penetrated by black tip 7.62 NEATO at <150m. And depending on how you classify it, even some four wheelers fall under the "APC" brand.

It wasn't the fact that the MiGs had guns, but it was the fact that the US didn't learn how to use their missiles effectively, while the Russians kept gunfighting as part of theirs.

It was a combination of gunfighters, halfway capable air defense fire from the ground, zerg rushing tactics on the American side, and the plain fact that Vietnam had less aircraft to shoot down. I think the final score is Vietnam lost 150 jets in combat of all types, whereas America lost 1500 jets in combat. Not 100% sure on the numbers, but I know it was a 10:1 difference.

The issue with cannon in air to air combat isn't that its somehow a massive advantage, but that in 1/10 situations that a fighter finds itself in actually requires the use of the cannon, and its absence is felt strongly by pilots that don't have it. Maybe it means losing a fight, maybe it means letting an easy kill go home. Its just still not worth the weight savings that are equivalent to one extra pylon carrying one sidewinder.

>Korean losses

Those were made because the US and USSR had Parity with their aircraft, Vietnam was different because the F-4 was 2 generations ahead of the MiG-15 and 17 and 1 generation ahead of the MiG-19, MiG-21s were on par but had very little numbers and were thus ineffective.

The US did not know how to correctly utilize their aircraft and paid for it early in the war. You'll see the same with the F-22 and F-35 vs 4th and 3rd Gen Aircraft still in service.

>>559486

I'll find the numbers for you, but it had more to do with the TOPGUN program than just the guns.

They were lobbing the missiles without locking onto target (similar to what the Vietnamese did with the MiG-21) and had to learn how to use them properly. This did more to fix the fight than just the gun.

As anon said, the gun is more like having a knife when you run out of bullets for your guns, it's nice to have when you run out of missiles or in a sticky situation where you can shoot down an aircraft while maneuvering.

Nevermind, found it in wiki:

AIM-7

>25,000 AIM-7Es were produced, and saw extensive use during the Vietnam War, where its performance was generally considered disappointing. The mixed results were a combination of reliability problems (exacerbated by the tropical climate), limited pilot training in fighter-to-fighter combat, and restrictive rules of engagement that generally prohibited BVR (beyond visual range) engagements. The Pk (kill probability) of the AIM-7E was less than 10%; US fighter pilots shot down 59[Note 1] aircraft out of the 612 Sparrows fired.[7] Of the 612 AIM-7D/E/E-2 missiles fired, 97 (or 15.8%) hit their targets, resulting in 56 (or 9.2%) kills. Two kills were obtained beyond visual range.[8]

>In 1969 an improved version, the E-2, was introduced with clipped wings and various changes to the fuzing. Considered a "dogfight Sparrow", the AIM-7E-2 was intended to be used at shorter ranges where the missile was still travelling at high speeds, and in the head-on aspect, making it much more useful in the visual limitations imposed on the engagements. Even so, its kill rate was only 13% in combat, leading to a practice of ripple-firing all four at once in hopes of increasing kill probability. Its worst tendency was that of detonating prematurely, approximately a thousand feet in front of the launching aircraft, but it also had many motor failures, erratic flights, and fuzing problems. An E-3 version included additional changes to the fuzing, and an E-4 featured a modified seeker for use with the F-14 Tomcat.

AIM-9B

In total 452 Sidewinders were fired during the Vietnam War, resulting in a kill probability of 0.18.[16]

>~10g filler

Is there anything that would prevent the reintroduction mine rounds? They managed to squeeze 18,5g of PETN filler into a smaller round (20x86mm) during WW2.

Don't worry we'll stick to bombing durkas, they don't have jets. Politicians have learned long ago to stay away from competent enemies.

Unfortunately in this case fragments matter more than explosive filling, when killing soldiers on the ground. That's why even the 20mm shells in use for the M197 this thing will likely be packing should probably have their explosive load reduced to fit proper preformed shrapnel. Also why that guys complaints about explosives were weird.

>>559525

Some were, I think some Zeros were modified as seaplanes. But the floats kept them back, they do add drag and make it harder to turn. Less of an issue for tactical bombers and multiroles, whose main job will be strike missions.

I feel bad for constantly bringing it up, but how about thermobarics?

So the most obvious solution also have some serious drawbacks. And thinking up a retarctable float now would be a bit late to the party. Still, seaplanes sound like the best thing ever for the Pacific front.

Even here people have forgotten that the PBY catalina had a positive kill ratio against zeroes in the pacific, in addition to everything else it did. In my opinion, this was because the PBY crews had a lot more time to train and get used to their planes pre-war, iirc it was first made in 1936 and remained both in service and effective throughout the war.

For a looooong time i thought the Marines would love a floating, flying gunship, an amphibious ac-130 able to refuel/rearm on ships at sea or at any harbor with diesel and ammo. (diesel and jet fuel are almost interchangeable, easy to design into the engines. Many engines already use either). Guns will need to be mounted much higher in the fuselage than on the ac-130, to not catch too much water on takeoff/landing. Perhaps this would work better as an airframe that can be either a gunship or AWACS for the carrier group, that way one ship could service four or five large aircraft running a near-constant patrol around the carrier group. The plane would be a four-engined turboprop, The japanese us-2 recon/coast gaurd plane is almost exactly the right plane to do this to. As it stands, the planes are equipped for search-and-rescue and apparently anti-submarine work, but have th payload capacity and range for what I'm envisioning.

The main problem i see with this is that releasing a gunship from the shackles of an airfield also mean it can effectively operate in places friendly fighters can't(at least not for the time a gunship needs to do its job) due to fuel range limits. However this isn't very important in counter-insurgency warfare.

>>559138

God I wish i was burt rutan, he's basically this generation's kelly johnson. So many fantastic designs. I wonder if you could make a velocity into a v-bomber with some small turbojets. Some napkin-tier math told me it would need about 1000f*lbs of thrust to match the 180hp twin props. Two engines mounted inside each wing with intakes at the wing root leading edge. Am i retarded for wanting this?>▶

Fun fact: M67 hand grenade has filling ratio of 45%, 20mm mine rounds has 20% filling ratio. Makes you think about case weight.

But how did they win dogfights? Or did zeroes just fly into the arc of their guns?

As far as I know the US armed forces only use one kind of jet fuel in all of their vehicles.

>Guns will need to be mounted much higher in the fuselage than on the ac-130, to not catch too much water on takeoff/landing.

I vaguely remember a similar discussion from a long time ago where an anon suggested putting the guns on the bottom in turrets, but it was shot down because the bottom of flying boats need to be quite sturdy. But how about going the opposite direction and mounting them on top of the plane, in turrets? They could still fire a broadside against ground targets if they can be depressed while facing left or right. And if they are 30-60mm autocannons, then they could be used as CIWS.

The side would still be the best bet. It would just be a little higher with the floats on…

The C-130 already has a seaplane version, I don't think it would even be difficult to convert the AC-130 into a seaplane version.

They still got more kills with the AIM-7s and AIM-9s however.

Sure they were unreliable, but they gave more reliable kills than guns.

There is a way to pull it off, most rounds, even artillery, have very little filler for round mass.

This is because you need the round to "protect" the filler while in the chamber from the high pressures.

The easiest way to deal with this, is using a lower pressure system (as with the 20x82 rounds they had much lower pressure than the 20x139 used at the time) so they can use heavier rounds, at the cost of velocity. Another example is comparing the SBD GBU-39 to the Mk82. The GBU-39 uses basically fiberglass for its outer shell while the Mk82 is still an iron bomb. The GBU-39, however, is much lighter at almost half the mass (129kg) compared to its Mk82 partner (227kg) but carry about the same amount of filler (GBU-93 has 93kg while the Mk82 has 87kg).

The best system to deal with a thinner casing is to lower chamber pressure.

How would you do this? With a high low pressure system.

Think of it as a reverse rocket system, all the high pressure is kept within the case and chamber, but the gases bleed over time out the top of the case through holes.

This way, you can propel more filler, for less overall round mass with similar velocities.

If you want to propel the same round mass with even more filler at the same velocity, it's about the same (give or take 10-15%) amount of propellant.

There's more advantages as well, you can make the gun itself lighter since the barrel doesn't have to deal with as much pressure as it gradually expands evenly along the bore rather than a sharp dropoff.

It's already used in grenade launchers, the Germans during WWII tried using it for antitank guns (the 8cm PAW 600 comes to mind, there were also plans for a 10cm called the 10H64 but that never came to fruition) and post war in some anti sub launchers, but that's about it.

>>559581

The same can be said of VTOL turbine aircraft. The USMC used Harriers in Iraq out of a football stadium and kept them well protected, it's also the way they use their Cobras, unlike the US Army who keeps them at airstrips, they have an Arming point close to the front lines with just a few trucks and personnel to load them up and send them off. Same can be said of the V-22.

But you have one thing, Aircraft Carriers (and LHDs in the case of the Harrier, V-22 and F-35B) basically do the same thing you're talking about but would need the ship close by to pull it off.

There's also the issue with jet aircraft of sucking in sea water at takeoff in the wake it would create and all of that that I'll get into if you want to discuss it further.

Point at him and laugh.

Wiki normalfags explanation for high low pressure system and is benefits is completely wrong.

More relevant use was in the Kampfpistole. Tweaked burger copies of this Wunderwaffe after became M79/M203.

wew lad

>The benefits mentioned are wrong

I didn't explain all of them, but it used thinner walls for projectiles and held the same amount as filler as its higher pressure counterparts.

It also used less propellant for almost half the mass of the projectile used in the PzGr. 38 HL/B round (2.7kg compared to 4.57kg).

It was not. Kampfpistole was made from the ground up. Later there was also more numerous Sturmpistole, mod kit to turn flare gun into weapon able shoot rifled ammo for Kampfpistole. This rifled ammo had high-low pressure propellant system.

Third Reich literally invented all weapons.

If it can carry AA missiles, parasite fighters/drones like the Zveno, or just refuel the escorts mid-air, that should not be an issue.

Excuse to post pictures of the SeaMaster

Seamaster-like flying boat bombers should have been our main strategic bomber, not B-1 or B-2. Flying boat bombers can operate anywhere in the world we have a carrier battle group, or a single supply ship. So they can take part in any operation, at any time.

We had to launch B-1 and B-2 from Europe, and mid air refuel, to use them in the middle east. This means that observant enemies could easily put spotters outside the airbases in Europe, and warn their friends hours ahead of time about incoming bombers. This is what happened to us in Yugoslavia, the Serbs put spotters outside the Aviano airbase in Italy and they knew the exact bearing, and based on cruise speed could calculate the location of the F-117.

God knows how fucked we would be if we had to use ground based bombers in China sea.

I would expect any serious attempt for RCS reduction, similar to the B-2 and B-1B, to be a maintenance nightmare for a flying boat that would have to deal with more salt than the usual carrier-borne spray.

Well it doesn't need to be stealth, in fact it should be made from all-stainless-steel construction for extra cheapness, rigidity, and resistance to rust. Better to have 1000 cheap aircraft that can take a hit and are so expendable that entire fleets of them can be scrapped for an upgrade…. than to have 10 glorified white elephants that need to desperately be kept in service for generations, and are unusable in combat.


4ee5ff No.560706

I have to point out though that it's critical for a strategic nuclear platform to be able to deliver its load instead of just zerg-rushing enemy air-defenses. If it was WWII where heavy bombers were expected to mass cheap dumb bomb a generic area your suggestion would have significant merit but delivering broken arrows to the enemy's door doesn't sound as a particularly good idea.


06b454 No.560721

Instead of wasting billions making a plane stealthy why not decide to not make a plane at all yet say it's there? Imagine how much resources will be wasted trying to find a plane that doesn't exist?

If you're speaking of peer fights between superpowers, a bomber is a really dumb way to deliver a payload. That type of thinking really IS a mainstay of WWII thinking.

Nowadays a few multirole aircraft with buddy refueling can deliver a city busting nuke. Or any number of ballistic and cruise missiles.

>>560721

That's actually a viable tactic in game theory, America has used it several times, Arabs and Asian countries do it pretty much 24/7.

I think our strategy is better, by using it only once every little while, it makes it hard to guess whether we're bluffing at any given moment. Whereas everyone who has followed Chink threats for the past 50 years thinks they're a paper tiger no matter what technology they adopt because they have always lied in the past.

Never bluff to Soviets though, they can smell it coming a long way off, because they do it so rarely. Very expensive for them though.

A seamaster-type plane would be suboptimal for for bombing and shouldn't be used for it. The way bomb bay doors work makes the seaplane bomber rather hard, now your seal has to be watertight as well, adding significant weight depending on the type of seal and perimeter it needs to cover (basically like pressurizing a bomb bay) The only advantage of a seaplane bomber is being able to resupply at a seaplane tender at sea rather than needing to all the way back to a freindly airbase, improving effective area.

It would, however, be fantastic for a carrier/fleet based awacs/beyond-the-horizon radar system, as well as a tanker. In fact, the Seamaster probably would have excelled in this role especially, it has the right flight envelope to refuel the many airplanes it would need to and enough gross weight.

The amphibious C-130 is pretty much exactly what i think they need. Rather than land your cargo on the carrier, why not land on the water?

(While they apparently can land a c-130 on a nimitz or ford class carrier, i doubt they can do it anywhere close to max weight)

It would also prove useful for all the auxiliary shit the USAF finds itself doing with its c-130 fleet. Imagine the whole Harvey relief supply thing, except the ocean was a runway too. I have a friend who lived in the area who did nothing but unload c-130s as a volunteer. With a seaplane fleet, you could almost litterally zergrush all your emergency supplies into any coastal location at once given decent enough conditions.

I'm a big seaplane advocate, I think the world needs more of them.

>>559816

The intake issue is minor, and has been solved before. Pic related, 20yr old russian seajet. The issues i would be worried about is corrosion and seaworthiness in high waves, but i suppose the soviets solved the corrosion part. But being able to land the plane in most situations

>>560751

I'm saying the seaplane will be better for all the supporting roles in the airforce, namely awacs and refueling. Especially refueling.

Imagine the falkands bombing raids if the RAF could have simply acquired a single oil tanker carrying jet fuel and flown a hypothetical seaplane tanker directly up to it to fill up. It would have been half as complicated as it was.

Or if the bombers were resupplied directly by a ship some 500m offshore of the falklands.
