 The Naval Sustainment System Supply, or NSS Supply, is a combination of commercial best practices, process improvement, governance, and oversight to maximize effectiveness and affordability within available means. It is a crucial component of NSS, a VCNO-led Navy-wide initiative embracing industry best practices tailored for Navy requirements and fleet operations. The Navy requires a single, strategic-scale, sustainable design for integrated Navy-wide supply chain with the right mix of organic and commercial activities to project and sustain a war-fighting force. Commander Naval Supply Systems Command, rear-admiral Peter Stamatopoulos, is overseeing an initiative called NSS Supply, which will govern end-to-end Navy supply chains through better collaboration, integration, and synchronization of supply chain operations, activities, and investments to amplify readiness within available means. As the supported commander, NAVSOP's efficacy is enhanced through the support of other Navy Systems Command, Hype Commanders, and program executive officers. Together, their leadership, engagement, and alignment from a whole-of-Navy approach will propel the Navy supply chains in the 21st century, which are increasingly global, interconnected, and intensely competitive. Central to NSS Supply is a supply-effectiveness figure of merit, a mathematical calculation using data applied throughout our supply chains to reveal where readiness and cost can be indexed. NAVSOP has already benchmarked a Navy against best-in-class industrial companies that, like NAVSOP, also sustain globally deployed equipment with long-sustainment tails and operate complex supply chains, revealing opportunities for better performance and affordability. Achieving these goals will require end-to-end integration of existing supply chain resources. NSS Supply will also delve into how demand management can reduce demand for parts and increase their reliability through design, engineering, and maintenance. Taking a portfolio management approach to managing cash outlays to maximize readiness will optimize the Navy Working Capital Fund allocation. Additionally, NAVSOP aims to optimize the mix of commercial and organic repair to increase Navy's repair volume and self-sufficiency. And shortening repair turnaround times in line with commercial industry will increase end-to-end velocity and move parts faster through the system. NSS Supply will globally integrate Navy supply chains to run more effectively and affordably to generate greater readiness. NAVSOP and the Navy Supply Corps are postured across Navy to improve performance with its strong leaders and wide-ranging assertive engagement plans. NAVSOP's oversight of this initiative will ultimately deliver more steaming days, more underwater days, and more ready aircraft to ensure our Navy's readiness and combat power never fails.
