South Korea is about to get some serious tech help from the U. S. President Donald Trump announced that America will share its top-secret nuclear submarine technology with South Korea. This is a huge deal because the U. S. usually keeps this kind of information under lock and key. The news came after a meeting between Trump and South Korean President Lee Jae Myung. Lee wanted to make sure everyone knew that South Korea isn't looking to build nuclear weapons. Instead, they want to upgrade their military to keep up with the times and reduce the financial burden on the U. S. Right now, South Korea's submarines run on diesel. They have to surface often to recharge, which isn't ideal for tracking other submarines. Nuclear-powered subs, on the other hand, can stay underwater for much longer. This upgrade could give South Korea a big advantage in monitoring activities in the region.
Trump mentioned that the new submarine will be built at the Philly Shipyard, which is now owned by South Korea's Hanwha Group. South Korea has promised to invest $150 billion in America's shipbuilding industry, but the exact cost and size of the submarine project are still unclear. This announcement comes at a tense time. North Korea recently showed off its own nuclear-powered submarine, which is a big threat to both South Korea and the U. S. Adding to the tension, North Korea also tested new cruise missiles while Trump was in South Korea. The U. S. has always been very protective of its nuclear submarine technology. Even when they shared some info with the UK and Australia, they didn't give away the full details. So, why are they sharing it with South Korea now? That's a question many are asking.
