Executive summary: It is clear that the Houthis have other satellite navigation devices, most of which are controlled by Russia, such as Glasnas.
The Palestinian-Israeli war has not yet subsided, and earlier, the situation in the Red Sea region deteriorated sharply due to the joint air strikes launched by the United States and Britain against Yemen, and it has become a "powder keg" in the Middle East that is not inferior to that of Palestine and Israel.
A spokeswoman for Yemen's Houthi group said the Houthis fired a rocket that attacked Britain's "Ruby", and the ship later sank to the bottom of the sea. At the same time, the Houthis used multiple anti-ship missiles to attack a British warship and two American cargo ships, both of which were badly damaged and in danger of sinking.
For the first time, the Houthis also released a photo of an American drone and a destroyed drone that could be identified by the fragments of the aircraft as the American MQ-9.
It is worth mentioning that earlier this year, after the United States carried out an air strike on Yemen, it completely cut off Yemen's global positioning system, but the various missiles of the Houthis were still not disturbed in any way, they accurately hit the United Kingdom and the United States, and even destroyed a US warplane.
It can be seen that the Houthis should have mastered more satellite navigation equipment and applied it to Russia's Granas satellite navigation system.
Russia has nothing to do with the Houthis, but Russia has a very close relationship with Iran, which not only bought Russian arms, but also established a channel for information exchange with them, and after the assassination of Soleimani, Russia handed over control of the Granas to Iran to assist it in attacking American bases in Iraq.
Most of the Houthis' ** and missiles are imported from Iran, and it is not surprising that Iran shares Russia's Granas satellite positioning system with them.
It is worth mentioning here that in 2019, China and Russia signed the "Cooperation Agreement between the People's Republic of China and the Russian Federation on the Peaceful Use of Beidou and GLONASS Global Navigation Satellite Systems", and conducted in-depth cooperation between the two countries in navigation. As for whether there is an exchange or not, then no one knows, everyone has their own opinion.
For example, on February 18, the United States intercepted a cargo ship transporting arms for the Houthis in the Red Sea, which was equipped with a built-in underwater thruster to equip the submersible.
Considering that the United States intercepted one of the Houthi submarines on February 17, it is estimated that Iran also sent the latest unmanned submarine to the Houthis, because this equipment has never been shown in front of the Houthis and should be the latest.
Iran now has two unmanned underwater vehicles, one is a Russian nuclear submarine of the "Poseidon" type, but it is much smaller than the Houthi nuclear submarine, with only a 533 mm warhead.
In addition, the Houthis have recently used unmanned boats such as Iranian unmanned motorboats to attack U.S. warships, which do not have the function of over-the-horizon warfare, and usually use drones as relay and remote control means, which cannot effectively hit modern ships.
Iran's latest unmanned equipment ** is undoubtedly a new test for the US Navy, in the Red Sea, American warships have to deal not only with cruise missiles, but also with a variety of new types of attacks, such as drones and drones.
Although it is not too difficult to intercept it, the cost of this UAV is very low, and the US equipment is often tens of thousands or even millions of dollars, which is inferior to the former in terms of cost and output.
It can be said that if the United States still wants to use violence to suppress the Houthis, then the US Navy's fleet and other military targets in the Red Sea will face a huge threat, and a previous attack on a US base in the Middle East, as well as attacks on US and British ships, all show that the Houthis have the strength to compete with the US ** team.
Neither the momentum of US expansion nor the maintenance of this situation will not last long, and the US is likely to make a difficult choice in the coming year.
Once withdrawn, the US hegemony in the Middle East will be dealt a great blow, and the Arab Sunnis no longer believe that the US force can shelter them, and it is very likely that they will turn to Iran, thus causing the US to lose control of the Middle East.
If the war continues, not only will the United States suffer a big loss, but the escalation of the Russian-Ukrainian contradiction and the situation in the Western Pacific will also put the United States in a situation of "multi-front warfare", which will be a disaster at that time. In general, this time the United States is really pushing itself into a corner.
