That's adorable.

And my unit visited the GE factory in Vermont where they made them back in 1984. We got the full briefing. Did you know that they have an antique original brass-pedestal US Navy Gatling gun on display right there as you walk in the office at the test range at Camp Ethan Allen?

While the very first design of "Project Vulcan" back in 1946 was in 0.60-inch (15 mm) caliber, that caliber was quickly found to be insufficient to the task, was quickly replaced, and was never accepted for service.

The system that was first accepted for service in 1959 as the 20mm T171 Vulcan (later redesignated the M61).
After feeding problems with its linked ammunition, it was redesigned with a linkless ammunition feed system and became the M61A1, which subsequently became the standard cannon armament of U.S. fighters, starting with the F-104 Starfighter.

All the other subsequent calibers and uses, such as:
GAU-12 Equalizer – General Electric, 25 mm caliber
GAU-13 – General Electric, 30 mm caliber
GAU-19 – General Electric, 12.7x99 mm caliber
GAU-22 – General Dynamics, 25 mm caliber, 4-barrel version of the GAU-12 mounted internally in the F-35A and in external gun pods on the F-35B and F-35C
GAU-8 Avenger – General Electric, 30 mm caliber
M134 Minigun – 7.62 mm cannon
M163 VADS – self-propelled version of the M61A1 on an M113 armored personnel carrier

...all came later, and NONE of those were ever used in an ADA capacity (unless you want to count one failed attempt back in 1980 by the 9th Infantry Division at Ft. Lewis as part of the "High Technology Test Bed", to use M134s mounted on the back of Jeeps, towing a trailer full of ammo. Spoiler Alert: It never worked and they shit-canned the whole idea.)

An interesting side-note was that there were ADA units deployed to Vietnam with their M163 M113-mounted Vulcans, but they were used for ground defense in convoy operations. You could flatten a lot of jungle with a 20mm at 4,000 rounds per minute, and Mr. Charles would suddenly discover a renewed interest in going back to his hut that night.

The CIWS was a US Navy derivative that was used for close in air defence, and the land-based C-RAM, in both mobile and static applications, was a derivative of the CIWS. All using the M61A1 20mm Vulcan and none other.

And I have also heard the Dillon 7.62x51mm M134D minigun. Very close up as a matter of fact. Literally right in front of me. On multiple occasions. Close enough for me to touch, in fact.

I used one in combat in Afghanistan.

I have heard and seen the 20mm M61A1 cannon on the C-RAM fire from about 100 feet away, engaging incoming 107mm and 122mm rockets being fired at us, and had A-10's fire their 30mm GAU-8 cannon across my unit's front at taliban about 200 meters out at our front.

But, you've seen them fired on video. So there is that to consider.

As strange as this may seem to you, in the face of easily accessed and verifiable facts, I somehow continue to find your assertions of , "I bet...", and, "...probably...", to be somewhat less than entirely convincing.

But, all of that aside, your original statement is still in error. The "Iron Dome" system currently used by israel is a missile based system. Period.

Note: Downvoting the facts don't make them any less true.

Are you jewish?
Names are pointless, but identification is useful for detecting malicious groups and users. So I always use random letters and numbers no matter which site I'm on. A quick look at my profile will confirm that I'm not an alt.

I've told you what the rules are, if I see you doing it again I will.

It's not an rocket artillery system, it's a retarded rendition of C-RAM using missile interceptors.
This is why I asked if you are jewish. It takes ten seconds to look up to confirm what we've been saying with video proof.
The bizarre denial combined with the video above showing its failure leads me to believe you are working on behalf of israeli online intelligence. When videos like this show that not only is the iron dome not as successful as the israelis claim, but also probably responsible for many of the "rocket" attacks on israel, you have a knee jerk reaction. You know you need discredit the video, as that is your job, but you don't have a lie that they made for you, so you go to the first thing you can think of, which stupidly is deny the system even exists.

There are other possibilities that don't require you to be working for or with the jews, but aren't possible based on the content you've posted within this thread.

Now go ahead and call me an idiot/sperg/autist/etc so I know I'm right on the money.

The Tamir missile's onboard electro-optical sensor is a hybrid, IR/UV-shadow system that provides the final guidance course correction steering data to steer the missile to a PMP (point of maximum proximity) to ensure the best target effects for it's proximity-fuzed HE-Frag warhead.

Because of it's velocity, the warhead's fragmentation pattern isn't globular, as a static explosion would be, but resembles more of a conical "shotgun" pattern thrown toward it's target. That means that in order to be most effective, the missile must try to manuever to a point in space in front of it's target.

If it detonates close, but even a fraction of a second too late, this blast pattern can miss the target entirely. (Reference the Patriot missiles performance against the Scuds during Gulf War 1., Because of a sofware timing glitch, the early intercepts were detonating after they had already passed their intended targets.)

IR guidance systems have come a long way since the 1950's. They haven't been "tail-chasers" for a long time now. They steer towards a pre-predicted kill-point based on the target's calculated trajectory.

Another common misconception is that modern guided missiles rocket motors continue to burn throughout their engagement, allowing them to execute all sorts of 180-360 degree manuevers to seek their target. The missile's boost phase only lasts about 10 seconds, then it is as ballistic as any bullet, having only the energy budget that it has acquired during that boost phase to spend trying to hit the target.

Another commonly held misunderstanding is that IR guidance sytems will simply home on the hottest source in front of them. This is also no longer true. The software is tuned and updatable to target sources only falling within the actual thermal parameters of a valid target.

Like the bears porridge in the story of Goldilocks, if it's too hot, or too cold, it will be ignored. The thermal signature of a rocket or mortar will not match that of a flare, and the flare would be ignored.

Likewise, If you were looking at a pair of identical twins, visually alike in every way, but one of them casts a shadow, and the other one doesn't you would immediately know that some sort of fuckery was afoot. In the same way, if the IR signature doesn't match the UV-shadow silhouette, it will be ignored.

The strategy that is currently being pursued by Hamas is both simple and valid. Target saturation of the defense.

If the enemy has a fixed number of launchers and $50,000 missiles and reload rate, and you can churn out an almost unlimited number of Qassam rockets at about $20 a pop?

Quantity has a quality all it's own. And there is a certain elegance in simplicity.
