DoD spends between $10–$20 billion annually on corrosion prevention and mitigation. Proper surface preparation is critical for ensuring maximum adhesion and minimizing vulnerability to system degradation of function, nonavailability, accumulation of corrosion damage, and the accompanying loss of productivity due to costly repairs. To promote better corrosion resistance, DoD-P-15328 specified a wash primer containing hexavalent chrome (Cr6+) as the sole means to surface pretreat systems. While no other compound had been effective for prevention of corrosion across multi-metal systems, Cr6+ is a known carcinogen with elevated levels of volatile organic compounds and hazardous air pollutants.
To create a safer workplace for civilians and warfighters as well as lessen risk to the environment, the nominees led an Army Research Laboratory effort to transition to alternatives without loss of corrosion prevention effectiveness. In testing, three Cr6+-free pretreatments performed equivalently to the DoD-P-15328 wash primer in militarily relevant environments. However, because MIL-DTL-13924D, TT-C-490F, and DoD-P-15328 required the wash primer, a review, revision, or cancelation of these specifications was necessary to enable use of the alternatives. New guidance encourages Cr6+-free technologies and economical green methods for pretreating metals. Revisions to these specifications were pivotal to the Army’s goal of reducing impediments to readiness from environmental, safety, and occupational health risks. Through completing ongoing laboratory and outdoor exposure validations on Cr6+-free rinses related to MIL-DTL-16232G, further elimination of Cr6+ may be possible.

Human Systems Integration (HSI) is a comprehensive management and technical strategy applied to systems integration to ensure total (hardware, software, and human) system performance is optimized, increasing efficiencies and minimizing systems cost. Human performance enhancements correlate directly to enhanced mission and operational readiness. The major value of HSI is the integration of seven domains (manpower; personnel; training; human factors engineering; personnel survivability; habitability; and environment, safety, and occupational health) to reduce or limit total ownership cost. Studies have shown that implementation of a successful HSI program can furnish lifecycle savings of up to 40 times the amount invested in HSI early in a program’s lifecycle. HSI ensures people are fully and continuously considered during the design development and acquisition of all systems, facilitating acquisitions that meet total system performance requirements.
While a number of standards exist that are relevant to HSI, they apply to particular types of systems, are intended for specific HSI domains, or do not cover HSI in its entirety. Mixing and matching from disparate standards is inefficient and leads to omission of important considerations. The nominees coordinated among DoD, the Joint HSI Working Group, and SAE to create a comprehensive standard for HSI management, SAE 6906, which includes collaboration among HSI domains and coordination between HSI and other disciplines to optimize total system and human performance and minimize personnel-driven risks and customer ownership costs. In addition, SAE is creating DoD-wide standard practices for four HSI domains that lacked these practices.

- Landing Craft, Utility (LCU) 1700
The Landing Craft, Utility (LCU) is a key element in the Navy–Marine Corps fleet of amphibious craft. In regular use in peacetime and wartime, the LCU is valued for its large lift capacity, excellent operational availability, ability to operate both independently and in sustained environments, and operational flexibility. Designed for a service life of 25 years, the fleet of LCUs was decades overdue for replacement, leading to a complete lack of standardization, system and parts obsolescence, chronic maintenance issues, and suboptimal habitability. Though their innovative acquisition strategy and contracting approach, the nominees took advantage of the cost benefits of a robust competitive environment,harnessed the capabilities and efficiencies of a small shipyard, positioned the government to recapitalize a critical capability at the lowest possible procurement and sustainment cost, created the potential for continued substantial cost avoidance and cost savings, and ensured the continued availability of LCU.
The replacement program employs lessons learned and industry best practices to address the cost and technical risk of product obsolescence, incorporate open systems into the design, and improve craft quality, reliability, readiness, and capability. The final detail design standard will result in a fleet that is materially identical, leading to ownership cost reductions from the enhanced commonality of components in the LCU 1700 craft (and for some systems with other platforms), one design configuration for maintenance, and one training curriculum for the crew.
