I've already listed the Top 5 Melee Weapons in Gundam, so it's only proper that I list the ranged weapons of Gundam. Now, I say ranged, but I'm specifically referring to weapons held by mobile suits; stationary and battleship weapons do not count. This list is dedicated to the largest, most over-the-top guns in Gundam history. A prerequisite for this list is obviously power, but note that the list does not put them in order of power. The order will be determined by other things like its impact on the series, its stylishness, and my personal opinion.
5. GN Bazooka
The GN Bazooka is the Gundam Virtue's main weapon in Gundam 00. The Virtue is a heavily-armored, heavily armed type mobile suit that uses a "just aim, and fire" strategy in battle. To keep things short, the GN Bazooka is basically a high-powered beam cannon that charges via GN particles and fires a massive holy-crap beam. Just take a look at the video.
Need I say more?
4. Hyper Mega Bazooka Launcher
Just so they could get their point across, they decided to call this thing the 'Hyper Mega Bazooka Launcher'. The whole name is redundant twice and sounds like something a grade-schooler made up, but that's just how powerful it is. The Hi-Nu Gundam is already one of the most versatile mobile suits in U.C. history, and this happens to be its most powerful weapon. The launcher connects to the Battleship Ra Cailum's power reactor as it requires massive amounts of energy. In a single shot, it was able to break off part of the asteroid Axis. That is enough of a testament of its power.
3. Atomic Bazooka
You don't see tactical nuclear warheads used very often in Gundam, and that's mostly because the super weapons tend to be uber beam cannons instead of conventional weapons. Though, in the few moments that nukes have been used, they've been devastating. The most memorable instance is when Anavel Gato used one in Gundam 0083: Stardust Memory. With the stolen Gundam Physalis, he fires its unique Atomic Bazooka toward a Federation fleet and completely obliterates it. It was a chilling sight of destruction to be sure. Ammunition may be limited, but you only need one shot when it comes to tactical warheads.
2. Satellite Cannon
The Satellite Cannon is basically a portable weapon of mass destruction. It is the GX's primary weapon in After War Gundam X. Its power is so devastating that you can pretty much count on everything in its path to be incinerated. One shouldn't expect anything less from an over-the-top death laser, after all. Though, in exchange for power, the Satellite Cannon has a lengthy preparation process.
It first contacts a space station on the moon, and has it send microwaves that the GX absorbs to charge its Satellite Cannon. It then proceeds to charge for about 5 minutes. Considering how long a single sequence is, the GX would need a distraction or a hiding spot in order to use this weapon. Still, the end result makes it kind of hard to complain. Note that this weapon was instrumental in bringing about the post-apocalyptic world that Gundam X is set in. The Satellite Cannon has everything else beat in sheer firepower.
1. Twin Buster Rifle
Here's where personal bias comes in. Personally, I feel that there's never been a rifle more epic than the Twin Buster Rifle, used by the Wing Gundam Zero in Gundam Wing. The buster rifle was built with one strategy in mind: one shot kill. That's why the original buster rifle only had enough ammunition for three shots. The twin buster rifle is a vast improvement. It is two equally powerful buster rifles that can attach and separate into dual rifles. It doesn't seem to be limited by the limited ammo of the first buster rifle, firing controlled bursts rather than full-auto beams. When split in two, the Wing Zero can perform its signature move, where it holds both guns to the side and fires in a full circle.
Of course, the important thing about this weapon is its obnoxious power. Single shots destroy several mobile suits at a time, and concentrated shots do crazy things like destroy a piece of the battleship Libra and tear through several layers of underground shelter designed to withstand nuclear war. Watch the clip above. The rifle blasts are so powerful that the Gundam itself starts blowing apart due to consecutive concentrated shots. Obviously, the Twin Buster Rifle does not beat the other guns in power, but it sure beats them out in style.
