08 Dec 09. After years of unprecedented growth, the pace of overall U.S. defense spending appears to have reached a plateau, and will likely commence a steady decline in the coming years. That is not to say that the Pentagon’s base budget is due for major cuts in the near term, however. Rather, the basis for this anticipated downturn is a shifting security environment overseas, particularly in Iraq. Indeed, of the total funding obligated for military operations overseas since 2001, over 76 percent was spent in support of Operation Iraqi Freedom (OIF). The U.S. now has an exit strategy in place, and plans to remove its combat forces from Iraq by August 2010, and all remaining personnel by 2011. According to Forecast International’s latest analysis of the U.S. defense market, “Redeploying U.S. assets in Iraq will be a complex and costly process, and the need to repair or replace equipment damaged or lost in theater will only add to the near-term investment. Nevertheless, the report adds that as combat operations wind down and troops leave Iraq by the thousands, the overall financial burden on the U.S. will slowly begin to ease. This trend stands in contrast to deteriorating conditions in Afghanistan of late. “That conflict will require additional resources as the U.S. attempts to swing the tide of battle in its favor, and an uncertain timeframe makes long-term costs difficult to estimate,” says Shaun McDougall, Forecast International’s North America Military Markets Analyst and author of the report. On the other hand, less than 20 percent of all U.S. war funding has been dedicated to operations in Afghanistan thus far. Additionally, given its smaller contingent of U.S. soldiers, the yearly cost of operations there is not expected to match that of OIF, which required upwards of 160,000 U.S. troops at its peak. With regard to the Pentagon’s regular budget, the years of expansive growth have come to an end. Defense Secretary Robert Gates has identified a need for at least 2 percent real growth in the defense budget, in contrast to the administration’s initial plans for spending to remain essentially flat. “The pressure on DoD topline spending is only exacerbated by an economic downturn,” according to McDougall, “though the Pentagon has at least been spared the massive spending cuts that some countries have been forced to enact.” The U.S. is facing a mounting debt, however, and the long-term threat of entitlement programs remains as ominous as ever. In the midst of these challenges, the DoD plans to capitalize on the findings of the pending Quadrennial Defense Review to reshape its modernization efforts over the coming years. In many respects, the QDR is likely to back the strategic direction behind many of the program changes that have taken place through 2009, from tactical and strategic aircraft production to shipbuilding and missile defense. A large number of questions remain unanswered, however. “This is because many of the program terminations that were announced by Secretary Gates in April 2009 were simply the result of priorities being deferred or rewritten, rather than eliminated completely,” says McDougall. The need for a new presidential helicopter, enhanced search-and-rescue capabilities, and a follow-on to today’s long-range bomber fleet, for example, has not vanished. Uncertainties regarding technology development, cost growth, and service requirements have simply put programs such as these on a holding pattern until the Pentagon feels comfortable moving forward once again. Other programs, such as the Marine Corps’ Expeditionary Fighting Vehicle (EFV), will depend on fundamental strategic decisions within the QDR, including the Pentagon’s approach to seabasing and amphibious warfare.
