Navy to Christen Submarine Indiana From Department of Defense


WASHINGTON (NNS) -- The Navy will christen its newest Virginia-class fast attack submarine, the future USS Indiana (SSN 789), during an 11 a.m. EDT ceremony Saturday, April 29, at Huntington Ingalls Shipyard in Newport News, Virginia. Vice President Mike Pence, who


previously served as the 50th governor of Indiana, will deliver the ceremony’s princi- pal address. Diane Donald, wife of retired Adm. Kirkland H. Donald, director of Naval Nuclear Propulsion from 2004 to 2012, is serving as the ship’s sponsor. Indiana (SSN 789) is the 16th Virgin- ia-class fast attack submarine and the sixth


Virginia-class Block III submarine. This next-generation attack submarine provides the Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century. The submarine, which began construc-


tion in 2012, will be the third U.S. Navy ship to be christened with the name Indiana. The fi rst Indiana (BB-1), the lead ship of her class of battleship, served in the North Atlantic and later participated in the blockade of Santiago de Cuba during the Spanish-Amer- ican War. The second Indiana (BB-58) was a South Dakota-class battleship that earned nine battle stars for her service in the Pacifi c Theater in World War II. BB-58 fought in the Battle of the Philippine Sea and participated


a unique teaming arrangement between General Dynamics Electric Boat and Hun- tington Ingalls Industries-Newport News, are 7,800 tons and 377 feet in length, have a beam of 34 feet, and can operate at more than 25 knots submerged. They are built with a reactor plant that will not require refueling during the planned life of the ship-reducing lifecycle costs while increasing underway time.


NRL Breakthrough Enables Safer Alter- native to Lithium-ion Batteries

WASHINGTON (NNS) -- Researchers at the U.S. Naval Research Laboratory’s (NRL) Chemistry Division have developed a safer alternative to fi re-prone lithium-ion batteries, which were recently banned for some applications on Navy ships and other military platforms.

Rolison from NRL’s Advanced Electro- chemical Materials group are leading an eff ort to create an entire family of safer, wa- ter-based, zinc batteries. They have demon- strated a breakthrough for nickel-zinc (Ni- Zn) batteries in which a three-dimensional (3-D) Zn “sponge” replaces the powdered zinc anode traditionally used. With 3-D Zn, the battery provides an energy content and rechargeability that rival lithium-ion bat- teries while avoiding the safety issues that continue to plague lithium. Their research appears in the April 28


issue of Science, the premiere journal of the American Association for the Advancement of Science. Additional contributors to this research article include former NRL staff scientist, Christopher Chervin, National Re- search Council postdoctoral associate, Irina Pala, as well as industry partners Meinrad Machler and CEO of EnZinc, Inc., Michael Burz.


“Our team at the NRL pioneered the ar-


chitectural approach to the redesign of elec- trodes for next-generation energy storage,” said Rolison, senior scientist and principal investigator on the project. “The 3-D sponge form factor allows us to reimagine zinc, a well-known battery material, for the 21st century.”


Zinc-based batteries are the go-to glob-


al battery for single-use applications, but are not considered rechargeable in practice due to their tendency to grow conductive whis- kers (dendrites) inside the battery, which can grow long enough to cause short circuits. “The key to realizing rechargeable zinc-

based batteries lies in controlling the behav- ior of the zinc during cycling,” said Parker, lead author on the paper. “Electric currents are more uniformly distributed within the sponge, making it physically diffi cult to form dendrites.” The NRL team demonstrated Ni-3-D


Zn performance in three ways: extending lifetime in single-use cells; cycling cells more than 100 times at an energy content competitive with lithium-ion batteries; and cycling cells more than 50,000 times in short duty-cycles with intermittent power bursts,


similar to how batteries are used in some hybrid vehicles. With the benefi ts of rechargeability,


the 3-D Zn sponge is ready to be deployed within the entire family of Zn-based al- kaline batteries across the civilian and military sectors. “We can now off er an energy-relevant alternative, from drop-in replacements for lithium-ion to new oppor- tunities in portable and wearable power, and manned and unmanned electric vehicles,” said Long, “while reducing safety hazards, easing transportation restrictions, and using earth-abundant materials.” NRL’s work is funded by the Offi ce of

Future USS Tripoli Launched Following Translation


From SUPSHIP Gulf Coast and PEO Ships Public Aff airs


PASCAGOULA, Miss. (NNS) -- On April 9 the future USS Tripoli (LHA 7) conduct- ed a translation from land to the dry dock at Huntington Ingalls Industries’ (HII) shipyard. The translation was conducted in preparation of launching the ship which was successfully conducted on May 1. “It was probably the most well-execut-


ed translation event that we’ve seen on a larger ship,” said Cmdr. Randy Slaff , LHA program manager’s representative with Supervisor of Shipbuilding, Gulf Coast (SUPSHIP-GC). The translation required 247 jacking


and pallet cars to support the displacement of the ship and ensure even distribution throughout. The translation successfully completed following 19 hours of continuous work.


Following the translation, Tripoli was


successfully launched on May 1 after the dry-dock was fl ooded to submerge the ship and allow it to fl oat off for the fi rst time. “We’ve made tremendous progress on


Tripoli over this past month, completing two major production milestones,” said Capt. Scot Searles, Amphibious Warfare deputy program manager, Program Executive Of- fi ce (PEO) Ships. “Moving and launching a ship of this size is tedious work and our teams did a superb job executing.” Tripoli will incorporate an enlarged


hangar deck, enhanced maintenance facili- ties, increased fuel capacity and additional storerooms to provide the fl eet with a plat- form optimized for aviation capabilities. The ship is planned to be christened later this year with delivery planned for late 2018. As one of the Defense Department’s


largest acquisition organizations, PEO Ships is responsible for executing the develop- ment and procurement of all destroyers, am- phibious ships, special mission and support ships, and special warfare craft.


DoD Announces Navy Casualty From Department of Defense


WASHINGTON (NNS) -- The Department of Defense announced May 6, the death of a U.S. Navy Sailor who was in support of a Somali National Army-led operation with U.S. Africa Command. Senior Chief Special Warfare Operator


Kyle Milliken, 38, of Falmouth, Maine, was killed during an operation against al- Shabaab May 5 in a remote area approxi- mately 40 miles west of Mogadishu. “Senior Chief Kyle Milliken embodied


the warrior spirit and toughness infused in our very best Navy SEALs. We grieve his death, but we celebrate his life and many accomplishments. He is irreplaceable as a husband, father, son, friend and teammate - and our thoughts and prayers go out to his family and teammates,” said Rear Adm.
