sures allow us to be on station longer and to do our job better,” said Cmdr. Walter C. Mainor, commanding offi cer, USS William P. Lawrence (DDG 110). “The Navy has been at the forefront of energy innovation [for generations]. From coal to steam to oil, this is just another measure that the Navy is taking on and leaning forward for energy innovation.”
Guided-missile cruiser USS Mobile
Bay (CG 53), and guided-missile destroyers USS Chung-Hoon (DDG 93), USS Stock- dale (DDG 106) and William P. Lawrence are all operating in the Indo-Asia-Pacifi c using alternative fuel. Stockdale became the fi rst naval ship
to use the fuel blend for regular operations when it departed for deployment from San Diego, Jan. 20. Mobile Bay and the other destroyers received the biofuel during re- plenishments-at-sea from Military Sealift Command (MSC) ships. The alternative fuel is made from 10
percent beef tallow provided from farmers in the Midwest and 90 percent marine diesel, and is cost competitive with traditional fuels. It is used as a drop-in alternative, meaning no modifi cations to engines or operational procedures are required. The U.S. Navy’s carrier fl eet, including
USS John C. Stennis (CVN 74) has oper- ated using only an alternative fuel source, nuclear energy, since 2009. Nuclear power eliminates large-volume storage require- ments for fuel, increasing capacity for other consumables and improving sustainability. By diversifying energy sources, the
Navy increases the operational fl exibility of its ships and strengthens their ability to provide presence. There’s more to the Great Green Fleet than alternative fuel. JCSSG uses various
ECMs including energy-effi cient systems, and operational procedures to operate far- ther, stay on station longer and deliver more fi repower.
Chung-Hoon’s crew implemented a
temperature control initiative in May, ad- justing the settings of thermostats, ensuring that they are in proper working parameters, and fi nding and replacing faulty parts in the chill water cooling system. “Chung-Hoon’s temperature control
initiative is comprised of many small goals, and when they’re met, we’re hoping to reach our ultimate goal of being a more energy effi cient warship,” said Cmdr. Vic Sheldon, Chung-Hoon’s executive offi cer. Sailors replaced legacy lighting fi xtures
aboard all JCSSG ships with solid state lighting (SSL) lamps that use light-emitting diodes (LEDs). The new bulbs are rated for 100,000 hours of service life, compared to the 100 hours of use of an incandescent bulb. The cruisers and destroyers of the strike
group all have stern fl aps installed. These modify the fl ow of water under the ship’s hull to reduce drag and resistance. Mobile Bay has a fouling release hull coating, which makes it harder for barnacles and other or- ganisms to attach to the hull. Both of these ECMs reduce resistance through the water, thereby increasing fuel effi ciency. In March, William P. Lawrence sepa-
rated from the strike group for its Oceania Maritime Security Initiative (OMSI) tasking in the Western Pacifi c, but continued practic- ing energy-effi cient operational procedures as part of the Great Green Fleet. “In conducting the OMSI mission, fuel
conservation is an absolute must,” said Lt. Quinn Matt, William P. Lawrence’s chief engineer. “Due to the geography of the re- gion and the tyranny of distance, logistical

support is in short supply over large swathes of the Pacifi c. By adhering to our fuel con- servation measures, we are able to meet all our mission requirements and prolong operational endurance.” During OMSI tasking, William P. Law-
rence burned an average of 20,159 gallons of fuel per day, 4.4 percent of its total fuel capacity and 40 percent less than its average fuel burn rate in 2015. When operational tasking allowed,
the strike group conducted trail shaft and drift operations, which are both operational procedures U.S. Navy ships use to conserve energy use. Trail shaft means driving a ship with one of two propellers while the other remains out of use with a pitch angle set to minimize drag. Drift operations are just what they sound like, drifting with ocean currents. “We have a responsibility to protect our
Navy’s resources, and doing so increases our combat readiness,” said Lt. Cmdr. Lo- ren Nichols, JCSSG logistics offi cer from Aberdeen, South Dakota. “It’s as simple as turning off the lights in an unmanned space when you leave, and as complex as operating our engineering plants with advanced fuels in the most effi cient manner possible. It’s most importantly a team eff ort across the entire strike group.” The Great Green Fleet is implementing
alternative fuels, ECMs and operational pro- cedures with one goal in mind -- instilling a culture of energy effi ciency and fl exibility throughout the fl eet for the future. “This is about more than just saving
gas,” said Nichols, “The Great Green Fleet is a mindset change across the board.” The strike group is comprised of John
C. Stennis with Carrier Air Wing (CVW) 9 and Destroyer Squadron (DESRON) 21 em- barked, guided-missile destroyers Chung-
Hoon, Stockdale, William P. Lawrence and guided-missile cruiser Mobile Bay. CVW-9 consists of Helicopter Mari-
time Strike Squadron (HSM) 71; Helicopter Sea Combat Squadron (HSC) 14; Airborne Early Warning Squadron (VAW) 112; Elec- tronic Attack Squadron (VAQ) 133; Fleet Logistics Combat Support Squadron (VRC) 30, Detachment 4 and Strike Fighter Squad- rons (VFA) 151, 97, 41 and 14. Providing a combat-ready force to pro-
tect collective maritime interests, JCSSG is operating as part of the Great Green Fleet on a regularly scheduled Western Pacifi c Deployment.
US Naval Academy Inducts Class of 2020
By Mass Communications Specialist 3rd Class Brianna Jones
ANNAPOLIS, Md. (NNS) -- The U.S. Naval Academy welcomed the 1,184 men and women of the incoming Class of 2020 in Annapolis June 30 during Induction Day. Induction Day--or I-Day--marks the be-
ginning of a demanding six-week indoctri- nation period called Plebe Summer, during which civilian students are indoctrinated into military life. This indoctrination period is meant
to help plebes develop discipline, honor, self-reliance and organization. These attri- butes will provide them with the foundation they will need to be successful midshipmen and throughout their military careers. “Today is a really special day for these guys and girls,” said Midshipman 1st Class Ryan Bailey, one of the Plebe Summer detailers who will be training the plebes. “We’ve all been through it so being on the
