Trident ballistic missile flies with first 3D-printed part

Three-dimensional printing has been applied to handguns, rockets, hypersonic jet engines, bicycles, ears, objects d'art, and now submarine-launched ballistic missiles (SLBM). Lockheed Martin has announced that the first 3D printed components for an SLBM flew this week on test launches of three unarmed US Navy Trident II D5 Fleet Ballistic Missiles from a submerged submarine in the Atlantic Ocean. The component tests, which were conducted from March 14 to 16, are part of Lockheed's program to create an all-digital manufacturing process.Read More

Reversible fuel cell goes both ways for the US Navy

Boeing has delivered a new type of fuel cell to the US Navy for testing that can both store energy and generate electricity. Called a "reversible solid oxide fuel cell," it's designed to absorb energy from renewable sources, such as wind and solar, then release it as required to provide commercial and military users with a cleaner, more sustainable source of power.Read More

DARPA gives Northrop Grumman nod to develop unmanned VTOL flying wing for small US Navy ships

DARPA has revealed more details of the Tactically Exploited Reconnaissance Node (Tern) program that aims to turn smaller US Navy ships into miniature aircraft carriers for Unmanned Air Vehicles (UAV). Phase 3 of program to develop a tail-sitting flying wing designed to take off and land vertically from destroyers and other small ships was awarded to Northrop Grumman, which will build a full-scale demonstrator for sea trials.Read More

Robot uses heat to strip rubber off nuclear submarines

In 2007, International Climbing Machines (ICM) unveiled its Climber robot, which can scale walls and rounded surfaces using a patented seal system. Now, it's trying to interest the US Navy in using robots to take over the nasty job of stripping away the rubber anti-sonar cladding from the nuclear submarine fleet using a method that is both cheaper and safer than current procedures.Read More

Northrop Grumman set to develop tail-down UAV for DARPA's Tern program

The competition to fulfill DARPA's plan to turn US Navy destroyers and frigates into drone-launching aircraft carriers seems to be over as Northrop Grumman has unveiled its version of the Tactically Exploited Reconnaissance Node (Tern) Unmanned Aerial Vehicle (UAV). Based on the flying wing design, the Tern UAV lifts off vertically in a tail-down configuration and is designed to operate from the decks of smaller surface ships in the US Navy without the need for aircraft carrier-type runways.Read More

US Navy's first Zumwalt-class destroyer begins sea trials

The future USS Zumwalt has begun sea trials in the Atlantic Ocean. The largest destroyer ever built for the US Navy and the first of three Zumwalt-class destroyers left the General Dynamics' Bath Iron Works and traveled down the Kennebec River in Maine on Monday in the first of a series of tests leading up to her commissioning next year.Read More

TALONS effectively gives ships of all sizes skyscraper-tall masts

Warships are only as effective as far as they can see, so DARPA's Towed Airborne Lift Of Naval Systems (TALONS) research effort is aiming to extend their horizons by giving them a crow's nest 1,500 ft (457 m) tall by way of a towed parafoil. A TALONS prototype recently completed sea trials off the US East Coast as part of a project to provide ships of every size with better long-distance communications and situational awareness.

Raytheon tests new self-defense missile protection for shallow-water combat ships

In naval circles, littoral areas are the hotspots for future conflict, but sending ships close to shore is like steaming into a shooting gallery. To provide more protection, the US Navy recently conducted tests off the coast of California of Raytheon's SeaRAM defensive missile system, which fires supersonic, self-guided interceptors against in-coming close-range threats. The tests were carried out by the littoral combat ship USS Coronado (LCS 4) on August 14 as part of a live-fire exercise at the Naval Air Warfare Center Weapons Division sea range. During these exercises, Raytheon says that the Coronado detected, tracked, and engaged an inbound target using SeaRAM.Read More

First installed electromagnetic aircraft launch system demonstrated

The age of steam is over – at least, as far as US aircraft carriers are concerned. At Newport News, Virginia, the USS Gerald R Ford (CVN 78) successfully test fired a revolutionary Electromagnetic Aircraft Launch System (EMALS), which replaces the steam catapults that have been standard carrier equipment since the 1950s. The test made a literal splash because it involved an unmanned dead-weight sled rather than an aircraft, which landed about a hundred yards off the bow of the still under construction vessel.Read More
