According to a recent report on the website of the Spanish newspaper Abesai, unmanned systems have long been used as a practical weapon, but they have become a key tool to weaken the enemy in the current Russia-Ukraine conflict. Both Moscow and Kiev have demonstrated the effectiveness of unmanned systems in seizing positions or conducting rapid killing attacks. The report states that the development of unmanned systems is still in the stage of comprehensive expansion. Experts say that future wars will be unmanned. NATO is also aware of this and is preparing for it. In September of this year, NATO conducted a large-scale anti unmanned system exercise in the Netherlands, testing over 60 types of weapons to resist unmanned system attacks. Ukraine participated in such exercises for the first time. Geopolitical instability has led to a significant increase in military unmanned systems Spanish Navy officer David Castillo, who participated in a naval unmanned system exercise held in Portuguese waters recently, pointed out. NATO countries tested their ability to respond to future wars in this exercise. NATO has stated that it is intensifying its efforts to contain and respond to threats in the maritime domain in order to address a more challenging security environment. Its goal is to raise awareness among member states of the importance of emerging disruptive technologies, which means increasing joint exercises to ensure interoperability. This involves capabilities in the air, on the water surface, and underwater, as well as the protection of the seabed as a new important conflict scenario. The advanced exercise conducted by NATO in the waters off Portugal focuses on testing the ability to use unmanned systems in multi domain operations, anti submarine warfare, mine warfare, and protecting critical underwater infrastructure. The report states that the Spanish Navy already has some unmanned systems, but its most important system is still in the testing phase. All of these are being promoted within the framework of NATO's Maritime Unmanned Systems Development Program. The NATO Maritime Unmanned Systems Development Program aims to coordinate the use of unmanned systems by member navies. Its goal is to establish standards and protocols for the efficient and safe use of these systems in maritime operations. In this exercise, a Spanish Navy warship sailed into a narrow waterway that could potentially harbor danger. To prevent any risks, an unmanned boat has been deployed in front of the warship. In addition to serving as bait, unmanned boats can also send real-time images to warships and even be equipped with weapons. This scene is very close to the current war scene. This is a simulated scene of a Spanish warship in Portuguese waters. At that time, all crew members were on duty to simulate real conflicts. The report points out that one of the main functions of unmanned systems is to protect the safety of personnel. Castillo explained when talking about the "advantages" of unmanned systems: "If we had an unmanned boat that could approach a threatening coast, we wouldn't put personnel in danger. If we also equipped it with sensors and weapons, we would have the ability to expand our naval vessels." Spanish naval vessels, which have the ability to operate in coordination with unmanned boats, have participated in anti piracy operations in the Indian Ocean and have been deployed in the Gulf of Guinea. The ability of warships and unmanned vessels to coordinate operations is very useful in these tasks. Some other ships of the Spanish Navy have also begun to introduce this capability in their international operations. In this NATO exercise, the Spanish Navy collaborated with ten Spanish companies (three of which were directly related to the manufacturing of unmanned systems at sea) to test the operation of aerial, surface, and underwater unmanned systems. Castillo said, "Testing the military applications of these unmanned systems and their ability to coordinate with ships is crucial
