I'm strapped into my backward-facing seat on a COD, or “carrier onboard delivery” plane, the U.S. Navy workhorse that ferries people, supplies, and mail to and from its aircraft carriers at sea. I cinch the four-point harness holding me in place. Then I cinch it some more. When it’s as tight as it can go, an aircrewman walks by and yanks it so hard it squeezes the breath out of me. The hatch closes. Steam rises from the floor. Shit. I've watched the YouTube videos. I know what’s coming. Takeoff, a 30-minute flight, then landing on the USS Nimitz, decks pitching, plane wings waggling, tailhook dangling from the underside of the aircraft to catch one of four arresting cables stretched across the flight deck. Since it’s not hard to miss them all, the pilot will gun the engines at landing to enable an immediate relaunch. Which means that if he succeeds at trapping a cable we’ll decelerate from 180 nautical miles per hour to zero in about one second.
To get to the Nimitz, 100 miles off Honolulu, our turboprop is flying a 50-50 blend of biofuel and standard JP-5 shipboard aviation fuel. The biofuel is made from algae plus waste cooking oil. This makes us part of history, my aircrewman says, players in what the Navy calls the Great Green Fleet demonstration of July 2012. It’s paired with a three-year, $510 million energy reform effort in conjunction with the departments of Agriculture and Energy as part of a larger push to change the way the U.S. military sails, flies, marches, and thinks. “As a nation and as a Navy and Marine Corps, we simply rely too much on a finite and depleting stock of fossil fuels that will most likely continue to rise in cost over the next decades,” announced Navy Secretary Ray Mabus at the launch of the program back in 2009. “This creates an obvious vulnerability to our energy security and to our national security and to our future on this planet.”
The Navy has set five ambitious goals to reduce energy consumption, decrease reliance on foreign oil, and significantly increase the use of alternative energy. Part of one target is to demonstrate a Great Green Fleet by 2012, and that’s what’s sailing this July day in Hawaii’s cobalt-blue waters: a carrier strike group comprising an aircraft carrier, two guided-missile destroyers, a guided-missile cruiser, and an oiler. All are running at least partially on alternatives to fossil fuels: the Nimitz on nuclear power, the other ships on that biofuel-diesel blend. The 71 aircraft aboard -- Super Hornets, Hornets, Prowlers, Growlers, Hawkeyes, Greyhounds, Knighthawks, and Seahawks -- are burning the same cocktail as my COD. All of today’s biofuels are drop-in replacements for marine diesel or aviation fuel and are designed to run without any changes to the existing hardware of ships or planes. “No [nation] can afford to re-engineer their navies to accept a different kind of fuel,” Vice Adm. Philip Cullom, deputy chief of naval operations for fleet readiness and logistics, tells me.
The Great Green Fleet is debuting at the 2012 RIMPAC (Rim of the Pacific) exercise, the largest ever international maritime war games, engaging 40 surface ships, six submarines, more than 200 aircraft, and 25,000 personnel from 22 nations. For the first time Russian ships are playing alongside U.S. ships, and naval personnel from India are attending. Many fleets here are sharpening their focus on alternative fuels and working to assure the formulations are co-developed with their allies. “ We've had dialogue with the Australians, the French, the British, other European nations, and many others in the Pacific,” and they all want to take “the petroleum off-ramp,” Cullom tells me. “We don’t want to run out of fuel.”
You can’t live off the land at sea, which is why the Navy has always looked far into the future to fuel its supply lines; the job description of admirals requires them to assess risk and solve intractable problems that stymie the rest of us. Peak oil, foreign oil, greenhouse emissions, climate change? Just another bunch of enemies. So when the Department of Defense set a goal to meet 25 percent of its energy needs with renewables by 2025, the Navy found itself fighting on familiar ground. Four times in history it has overhauled old transportation paradigms -- from sail to coal to gasoline to diesel to nuclear -- carrying commercial shipping with it in the process. “We are a better Navy and a better Marine Corps for innovation,” Mabus says. “We have led the world in the adoption of new energy strategies in the past. This is our legacy.”
It goes beyond supply lines. Rising sea levels lapping at naval bases? A melting and increasingly militarized Arctic? The Navy is tackling problems that freeze Congress solid. What it learns, what it implements, and how it adapts and innovates will drive market changes that could alter the course of the world.
But not without a fight.
