From the dialogue between the characters in the movie screen and some related information, it can be inferred that this mysterious weapon is an electromagnetic gun.
The so-called electromagnetic gun, or high-energy electromagnetic railgun, does not launch an electromagnetic direct attack, but uses it as a driving force to replace traditional gunpowder to launch projectiles such as shells or missiles. According to the relevant data of the US military's experiment in 2008, the kinetic energy of the muzzle of the electromagnetic gun has reached a record level of 10 megajoules (actually it may have the ability to generate 32 megajoules of energy), making a four-kilogram shell at Mach 7. It flies at a high speed (7 times the speed of sound), with a range of more than 360 kilometers (traditional artillery tens of kilometers), and can carry out precise attacks with an error range of less than 5 meters. Such ultra-high-speed shells can directly destroy the target through impact.
In the movie, when Simmons was talking to the commander of the fleet to request support, because it was confidential and afraid that the other party would not admit that he had such a weapon, he mentioned speed (specifically, several times the speed of sound, which I have forgotten). According to the data, it seems that the electromagnetic gun can indeed achieve such a strike effect. However, the electromagnetic gun is still in the experiment (the experiment announced by the US military is about this time), and it is far from being able to actually board the ship to form a combat capability. The very cool and powerful electromagnetic gun in the movie is also non-physical. Now, some clues can also be seen from the movie screens. The first panoramic view of the battleship (the U.S. active destroyer Arleigh Burke class) was equipped with ordinary naval guns, and the latter close-up became a special electromagnetic gun.
As a result, this electromagnetic gun has become the only unreal US military weapon in the two "Transformers".
Let's talk about the US military's operations. Compared with the first episode, this episode is concentrated in the final rapid response operations.
The United States established a rapid reaction force in the early 1980s, and after the end of the Cold War, the Soviet Union collapsed, and the U.S. military’s global strategy made it even more important. The rapid reaction force has a high degree of mobility and strong assault capabilities. It can quickly rush to the accident area at any time to deal with emergencies. Even if there is no war, the rapid deployment force can also have a deterrent effect on the launch of a war by a hostile country. Of course, fast is not always a good thing. Too much emphasis on "fast" means that at the cost of losing "heavy", the vanguard troops without the cover and support of heavy weapons often suffer heavy losses or even fail to achieve their combat goals.
In the movie, in order to resurrect Optimus Prime against the fallen King Kong and Decepticons, special forces and Autobots have to parachute to Egypt. Airborne is of course the fastest way. It is also possible to fly directly from the United States to Egypt with a C-17 Globemaster transport plane (the full range of the C-17 is 4630 kilometers, and the maximum range after refueling in the air is 11,600 kilometers), but whether Being able to enter the airspace of another country like this is a problem.
In the movie, the US military encounters another problem, that is, how do they resist the Decepticon attack until they rescue Optimus Prime. They arrived quickly, but only carried individual weapons without any large heavy weapons (Autobots may be considered, but the number is very limited compared to the Decepticons), like relying on an old town in Egypt as a stronghold. It's really difficult. At this time, Starscream, who transformed into an F-22 fighter, conducted electromagnetic interference again, cutting off any contact between them and the outside world.
Fortunately, the head of the headquarters was considered wise. After losing contact, he immediately dispatched the most advanced RQ-4A "Global Hawk" unmanned reconnaissance aircraft to conduct field reconnaissance on the battlefield. How did the "Global Hawk" suddenly appear over a small village in Egypt? The reasonable explanation is that there is a US military base in Egypt not far from the village (and in reality, Egypt also has a US air base). It also explained the appearance of other aircraft in the back. The "Global Hawk" used the airborne camera to instantly transmit back to the battlefield. After understanding the situation at the US headquarters, it sent reinforcements.
Of course, reinforcements must be near the battlefield to arrive in time, and they consist of two parts. The first group is from the maritime marines or army units from the sea, which are divided into helicopters and hovercraft for landing and landing from amphibious warships. The helicopter was a bit miserable, and it became a live target when it flew. Both of them were shot down. Reinforcement failed but needed rescue. The hovercraft carried M1A2 main battle tanks and M2A3 infantry fighting vehicles and soldiers landed on the beach. After reaching the village (really unreal fast!), it can provide a certain amount of firepower and cover.
The other is air cover. Although there are F-18 "Super Hornet" fighter planes taking off from an aircraft carrier in the movie screen, this fighter plane did not appear over the battlefield. The other two types of F-16 fighters and B-1 stealth bombers that have emerged are not aircraft carrier-based aircraft. They also echo the existence of the US air force base mentioned above, and only B is actually engaged in combat. -1 stealth bomber. It carried out a carpet bombing of the entire village, as if it had also killed the Decepticons.
Then there is nothing about the US military in the movie, it depends on Optimus Prime.
The above is the rapid response operations of the US military, including airborne, reconnaissance, landing, and air support. Judging from the content, it is really trivial. It doesn't look like shooting a real battle, but rather like a self-directed and self-rehearsed exercise. In fact, there is news that the U.S. military's participation in the filming of the film itself was carried out as a training, and because the crew wasted some unnecessary munitions and used some in the filming that were deemed by the military to be inconsistent with the original intention of the training. For military resources, he also lost money to the U.S. Department of the National Treasury.
Does military training or exercises seem real? No, the exercise is pre-set in a presumptuous way, and it does not show the "realism" created by film fraud.
Lastly, let me mention "Skyfire". Although he is very old, his deformed SR-71 Blackbird reconnaissance aircraft is not considered antique equipment (retired in the late 1980s because it was not out of date but because it was expensive to maintain). There may be two reasons for choosing the SR-71 Blackbird reconnaissance aircraft: one is that the model of this aircraft is handsome enough, and the other is that it is the same as the F-117 stealth bomber that has been retired in the first episode. Nostalgia of classic fighters.
