The Navy is tight-lipped about what new technologies will be fitted to the large surface combatant. A group of bystanders look toward the wreck and the. The Navy plans to buy the first of these ships in the late 2020s. A car rests on its side and car parts litter the deck of the Liberty Memorial Bridge after a car accident.

The technology is also available for larger 155-millimeter projectiles, potentially giving the two Advanced Gun Systems on the Zumwalt-class warships ammunition for engaging enemy targets.Ī new warship, the large surface combatant, is scheduled to eventually replace the Ticonderoga-class cruisers. The vessel was privately owned but had been partly financed by the British government and was classified as an armed freighter. She was powered by a triple-expansion steam engine rated to 1,850 hp (1,380 kW). Deploying HVP to the fleet will give these ships increased capabilities, which is a lot cheaper than building new ships with railguns. The SS Thistlegorm was built by Joseph Thompson & Sons shipyard in Sunderland for the Albyn Line and launched in April 1940.

45 guns in operation, two on each Ticonderoga-class guided missile cruiser and one each on the Arleigh Burke-class guided missile destroyers. One huge advantage HVP has over the railgun: there are already more than a hundred HVP launchers in service. The guided-missile destroyer USS Dewey fired 20 HVP projectiles during the 2018 RIMPAC naval exercises, the first known use of the new weapons at sea. The Navy believes the HVP could be used for long-range strike missions against land targets, against aircraft and missiles, and against enemy warships. The projectile has a top speed of Mach 3 from a chemical energy gun-only half the speed as from an EMRG-but still an improvement over current 127-millimeter projectiles.
