The U.S. has built, or will build, more than 100 new submarines over the next decade, the latest of which, the SSBN-6, is expected to be ready for service by 2020.
The research, conducted by the American Society of Civil Engineers, found the U.K., France, Germany and Italy are among the best countries for building submarines.
“These countries are making a commitment to build submarines that will be able to meet the needs of their military and national security,” said Dr. Christopher Bremmer, an emeritus professor at the American Enterprise Institute and an expert on submarine warfare.
“The United States has been a leader in the sub-building game for decades and this new research shows that we are continuing that trend.”
The new study, which also looked at submarine parts from countries such as Russia, China, Australia and Brazil, found America is building the submarines at a rate of more than 10 new submarines a day, more rapid than any other country.
The number of American sub-buildings is increasing, while France, Italy and Germany have seen the number of sub-built subs grow.
Submarines have become a cornerstone of the U., British and German economies.
The U is the world leader in sub-mars, and its subs are used for training, anti-submarine warfare, and other operations.
Britain is the second-largest manufacturer of submarines, with more than 80 percent of its submarines built abroad.
China has about 2,600 sub-ships built and more than 2,400 of them in Japan, according to the Defense Industry Association.
Germany has about 1,600 subs in service and a few hundred in active service, while Australia has over 2,500 subs in active and standby status, according the Australian Maritime Safety Authority.
Italy has 2,000 submarines in service, according its defense industry group.
Brazil, France, India and Russia all have hundreds of subs in operation, according their defense industry groups.
Bremmer said the U’s new sub-sailing fleet is built at a cost of $1.2 billion, which has kept it from breaking the $1 trillion annual cost mark.
He said a recent submarine study by the Department of Defense estimated that about 70 percent of U.s. subs were in service before 2025.
“Our research shows we are building sub-capitals in the U and we are increasing our submarine presence.
But our submarines will have to be built in the United States and we need to make sure they are ready to go at the time we need them to go,” Bremer said.
Some countries have also been increasing their submarines.
Russia, for example, recently announced plans to build another 10 submarines.
But the program has not yet been formally approved by the U, Defense Secretary James Mattis has said.
Bremer also pointed to a new program called Project BALTOPS, which is aimed at boosting the U.’s submarine force.
The program will include a new submarine-launched ballistic missile system called the Kornet that could be operational by 2020 and would include a nuclear-capable submarine, Bremers report said.
In the future, submarines could be deployed from ships and other assets.
The U. S. Navy will soon begin building two new submarines at sea, the first of which is scheduled to be completed by 2019, according a recent statement by the Defense Department.
