Reaching these goals – or even advancing toward them – was intended to lead the Navy and Marine Corps (N&MC) toward energy security, sustainability, and operational flexibility. It might also save some lives. So, more than seven years later, how are we doing? Navy magazine decided to find out. Energy-efficient Acquisition GOAL 1: "Evaluation of energy factors will be mandatory when awarding contracts for systems and buildings." STATUS: In place and achieving strategic advan- tages and cost savings. To accomplish this goal, DoN issued "policy guid- ance" for acquisition planning, technology develop- ment and source selection in general, and the DoN has also supported developments that reduce fuel consumption in various weapon systems. When contacted by Navy magazine, SECNAV's office listed several projects the DoN was developing, including "engine im- provements…that have the poten- tial to enhance platform capability while cutting fuel use." One of these improvements is the Fuel Burn Reduction initiative for the Joint Strike Fighter (JSF), the F-35 designed and built by Lockheed Martin and other indus- try partners, including Northrop Grumman, BAE, and Pratt and Whitney. Matt Bates, Pratt and Whitney's Communications Manager, confirmed that "the Na- vy-funded F135 Fuel Burn Reduc- tion program demonstrated substantial compressor performance improvements in a rig test in 2015, and we are on track to demonstrate greater than a 5% mission-weighted fuel burn improvement in an en- gine test in early 2017." Since this engine is used in all three variants of the JSF, the cost savings over the 30-year lifespan of each jet would be significant. Another improvement is the adoption of hybrid engines. e Navy's first hybrid ship was the amphib- ious assault ship USS Makin Island (LHD 8), which saved almost $2 million in fuel costs during its first voyage from Mississippi, around South America, MC2 HUE Y D. YOUNGER JR. 24 Navy | Winter 2017 Hybrid Electric Drives now in use on Arleigh-Burke-class destroyers such as the USS Lassen (DDG 82) pictured above, patrolling the eastern Pacific, will allow the surface force to go farther without refueling and stay on mission longer. The Navy requires that all alternative fuels be "drop-in," meaning they require no modifications to engines or procedures.
