United States: mission reorganization unmanned submersible
Since the "long-term mine reconnaissance system" (a cable-free autonomous unmanned submersible) needs to be pre-programmed, only one type of task can be performed at a time, and the cost is too high. The United States terminated the follow-up of the project in 2008. Research and development work. Subsequently, the US Navy focused on the development of “reconstructed unmanned submersiblesâ€.
The “reorganized unmanned submersible†consists of two parts, the basic part and the task payload part. Among them, the basic part includes propulsion devices, batteries, navigation equipment, communications, electronic equipment, control equipment, obstacle avoidance equipment, deployment and recycling equipment, and equipment that guarantees the task of reorganizing unmanned submersibles for basic navigation functions. The payload portion is primarily a number of specific devices that are integrated with the basic parts of the mission reconfigurable unmanned submersible to perform the required tasks.

United States: Undersea System of the National Defense Research Institute - Hydra
The United States Defense Advanced Research Agency (DARPA) is preparing to develop an underwater mothership that can quickly resupply and equip naval personnel on nearshore facilities, submarines or surface ships or even aircraft. The project, called Hydra, is still in the early stages of planning. In August 2013, the US Defense Research Institute held an industrial briefing at the Johns Hopkins University Applied Physics Laboratory to solicit defense contractors. Design a plan to put this idea into practice.
At the meeting, the US Defense Research Institute elaborated on the project's goal of developing and demonstrating a UAV / UAV work network that should be able to transport, mount, launch or deploy multiple payloads, including no one. Aircraft, unmanned submersibles, etc. In the paper of the industry briefing, the project management department said that more and more intense piracy and the complexity of the defense system continue to dilute the naval resources, making the navy lack of energy to perform special operations and emergency tasks. The agency said it hopes to develop a mothership that launches small drones into the air through the Water Margin project and can be used in actual combat.

Through remote control, unmanned boats can deploy drones, which sounds a bit like science fiction, but it may be the form of future war. Similarly, the US Defense Research Institute is working with Lockheed Martin to develop drones that can transport equipment, cars, and even soldiers' cabins to land and air.
Similar to Lockheed's drone project, the Mink project is also designed to store and transport different types of loads using modular, standardized cabin structures. The US Defense Research Institute told reporters that under ideal conditions, the "Water Margin" unmanned boat/UAV can last for several weeks or even a month. The US Defense Research Institute hopes that this unmanned boat/unmanned aerial vehicle system will be able to demonstrate actual combat functions by 2018.
In addition to an unmanned underwater system development and demonstration, the program will provide a new delivery mechanism for deploying unmanned aerial and underwater vehicles. By using a payload module in a standard enclosed space, the "Water Margin" program will allow for scalability and provide a quick response to the Navy's cost-effective underwater installation.
Development of UUV in France
At the beginning of this century, France has provided about 350 ROVs for mine destruction in 14 countries. In recent years, they have proposed a new reconfigurable multi-purpose anti-mine device based on the Ultraster UUV, which is mainly military anti-mine, but when used in other military or civilian applications. Nearly 90% of its equipment is still applicable.
France has always had advanced technology in the field of anti-mine warfare. At the end of 2008, the French Naval Armaments Agency required the use of innovative UUVs to replace the fleet's 13 minesweepers, which may cost more than submarines. DCNS has obtained a contract for the technical transformation of these minesweepers. TUS has undertaken the design task of the anti-mine system and UUV from DCNS. The research is scheduled to be completed in July 2010.
The core technology used by TUS is the use of an autonomous UUV that separates it from the mother ship, so the mother ship no longer requires a specially designed minesweeper and the cost can be greatly reduced. This new generation of UUV for lightning protection has reached a new level compared with the ROV for lightning used in design 10 years ago. This is a true unmanned mine-sweeping technology.
French ECA companies claim that their fully autonomous UUV, called Alister, can perform tasks such as surveillance and mapping at 3000m underwater. Future high-performance fuel cells allow Alister to sail underwater for more than a dozen hours.
Development of UUV in Japan
Japan has invested in the development of UUV technology around the 1990s. The main research areas include: high-performance batteries, pollution-free propulsion systems, efficient heat engine technology, high data rate underwater acoustic communication technology, and low cost. Terrain matching and precision navigation technology, low noise and low electromagnetic sensor technology, coating stealth technology, artificial intelligence to control UUV, neural network and fuzzy logic, high reliability and low maintenance technology.
