The Army Equipment Program in support of the President's Budget 2015 (AEP PB describes the Army Research, Development and Acquisition (RDA) budget for key capability portfolio areas and the Science and Technology portion of the Fiscal Year 2015 (FY 2015) President's Budget request. The AEP PB 15 is renamed this year to better reflect the focus of the Army's portfolio management and equipment descriptions, but flows from the previous Army Equipment Modernization Strategy and 2014 Army Equipment Modernization Plan. This document delineates RDA investments into 11 capability portfolio areas, highlights the portfolio accomplishments over the last two years and provides intent for FY 2015 investments. The dollars and quantities in this document reflect President's Budget 2015. The objective of Army equipment modernization is to enable our Soldiers to fight and win across the entire range of military operations by developing and fielding versatile and tailorable equipment that is affordable, sustainable and cost-effective. The Army has developed several initiatives to guide equipment modernization during this period of fiscal constraint. The Total Army focuses equipping modernization on the Soldier and squad providing them with the Network and key enablers. We use incremental improvements to improve existing systems as our first option and build new systems only by exception. The Army is divesting older systems and niche capabilities to decrease sustainment costs and generate additional resources for modernization and readiness. Next, we are developing smaller procurement objectives because the Army cannot afford to equip and sustain the entire force with the most advanced equipment. Our procurements are to insert needed technologies and capability improvements, leveraging commercial investment where we are "technology-takers" (e.g., information technology, fixed wing aviation) and our own focused investments in technology where we are "technology-makers" (e.g., lethality, armor, rotary wing aviation). Finally, each equipment decision is reviewed to ensure it is both affordable within the overall budget and is cost-effective in addressing the capability gap.
