The U.S. Navy’s top officer wants directed energy weapons to become the go-to choice for the crews of American warships when faced with close-in threats. He also said that more powerful megawatt-class lasers should not be seen as “beyond” the capabilities that could be found on the future Trump class warships. The Navy has been a leader within the U.S. military in fielding laser weapons and is actively pursuing systems that employ high-power microwaves, but there continue to be significant hurdles to these efforts.
Chief of Naval Operations Adm. Daryl Caudle talked with TWZ and other outlets about his service’s directed energy weapon plans at a roundtable at the Surface Navy Association’s (SNA) annual symposium earlier today. Caudle has long been an outspoken proponent of directed energy capabilities.
“My thesis research at [the] Naval Post Graduate School was on directed energy and nuclear weapons,” Caudle said. “This is my goal, if it’s in line of sight of a ship, that the first solution that we’re using is directed energy.”
In particular, “point defense needs to shift to directed energy,” the admiral added. “It has an infinite magazine.”
When it comes to point defense for its ships, the Navy currently relies heavily on Mk 15 Phalanx Close-In Weapon Systems armed with six-barrel 20mm M61 Vulcan rotary cannons and launchers for RIM-116 Rolling Airframe Missiles (RAM). Each Phalanx has enough ammunition to fire for a total of around 30 seconds, at most at the lower of two rate-of-fire settings, before needing to be reloaded. RAM launchers available today can hold either 11 or 21 missiles at a time, and the latest versions of those missiles cost around $1 million each. Many ships across the Navy also have 5-inch or 57mm main guns, and/or 30mm automatic cannons, which can also be used against close-in threats.
