The US has occasionally showcased its submarines in the past, but the pace picked up in the last year with publicized port visits by nuclear-armed Ohio-class submarines as well as Los Angeles-class subs carrying conventional Tomahawk cruise missiles. Each of the subs carries up to 20 D-5 Trident ballistic missiles. The submarines, nicknamed Boomers, gained the silent service description because they are designed to glide undetected, and their port calls have seldom been disclosed - much less trumpeted - by their usually taciturn commanders. Pentagon officials confirmed that one of the Navy’s 14 Ohio-class vessels will visit, as President Joe Biden signaled in announcing a “Nuclear Consultative Group” during last month’s White House visit by South Korean President Yoon Suk Yeol.
