Possibly the most violent episode of the Star Wars saga, ROTS gives us detailed information on hand-to-hand weapons as well as shipboard weapons. Most notable are the details that can be discerned about lightsabers, and the introduction of something solid which lightsabers cannot cut.

The battle over Coruscant gives us detailed information on the range, yield, and maximum rates of fire. Respectively, a ship may fire dozens of shots per second with yields of up to a megaton, potentially exceeding 100 petawatts of effective weapons output. This may be directed at other capital ships closer than 50 kilometers.

Interestingly, weapon stations are actively manned on the Separatist side.

Torpedos are also in use, although not in a very conventional fashion.

Lightsabers can cut through many materials and will heat metals to incandescence. One interesting point comes when Yoda impales clonetrooper with a lightsaber like a javelin; the saber remains stationary in the trooper while Yoda flips up. Apparently the blade of a lightsaber is tangible, rather than being a near-line perfectly sharp along all sides.

Lightning staves cannot be cut by lightsabers; they are fairly hard and strong, as evinced by the use of one by General Grievous to shatter a bridge window. There are some shock effects associated with them.

Buzzdroids are small sabateur-droids, used as warheads for droid-launched missiles, which appear to have at least several kilometers of range and a high degree of maneuverability.

Capital ships are seen blasting each other with blue and red turbolasers at point blank range; these blasts create small explosions when effects are visible, slowly chewing apart larger ships in firey bursts. Some turbolaser bolts have enough energy to "vaporize a small town," which could easily refer to megaton-range blasts in spite of the relatively small explosions seen onscreen.

The partial disintegration of the Invisible Hand on re-entry, combined with the collision effects seen, suggest strongly that the yields seen impinging on the armor of the various warships are not much more than a megaton at the greatest. In consideration of both forms of evidence, we may suggest yields of 10-1,000 kilotons per shot.

The range of weapons fire between capital ships remains on the order of kilometers to tens of kilometers. A more precise safe distance is given by General Grievous in the novelization: "I have a counteroffer. Maintain your ease-fire, move that hulk Indomitable out of my way, and withdraw to a minimum range of fifty kilometers until this ship achieves hyperspace jump." This suggests a maximum effective firing range of fifty kilometers.

The fact that the rate of fire seen in the battle cannot be sustained for long is also exhibited in the novelization, which notes that a "pause in the combat would allow Invisible Hand's turbolaser batteries to cool," i.e., the weapons were overheated. The rates of fire seen in the battle appeared, in many cases, to be up to five per main turret per second, suggesting a rate of up to forty bolts per second for the Republic attack cruiser. Return fire comes at similar rates.

If the Republic attack cruiser fires up to forty megaton-range blasts per second, this is a peak weapons output of 170 petawatts. Using the mean guess of 100 kilotons, peak weapons output is 10-20 petawatts.
