Thanks to technological innovations and growing commercial and military demand, the global aerospace and defense industry has held up nicely this year. However there are concerns that the biggest consumer of defense equipment, the U.S. government, might cut their defense spending in the near future, potentially derailing growth in this corner of the market going forward.

This trend is further spread out across the globe in a number of other key markets such as United Kingdom, France, Germany and Spain. However, the investors focus more on the trend in the U.S.-- the dominant player in this market, with nearly half of total military spending in the world, easily outpacing the next five biggest spenders combined (read: Can The Defense ETFs Soar Despite Headwinds?).

The U.S. military is facing possible cuts of $500 billion over the next decade (2012-2021), including $55 billion for 2013, if the Congress fails to find ways to reduce $1.2 trillion of fiscal deficits before the end of December.

In this difficult scenario of tight budgets and cuts to big programs, acquisitions offer big defense companies a way out to bolster their financial positions. Strategic alliances among companies have also been on the rise. The defense operators at times join forces with each other, bring along their individual expertise on the table and work as a cohesive unit for big defense deals.

Additionally, big international orders will also add to the growth of the aerospace and defense companies especially when the U.S. government is taking proactive steps to trim the defense budget. Further, a number of new emerging markets as well as developed nations, such as India, China, Japan, the United Arab Emirates, Saudi Arabia, and Brazil are boosting defense spending.

Considering the broad issues and opportunities, many aerospace and defense companies are holding up steady and, hence, investors could benefit from these positive market trends. A look at some of the top ranked ETFs in the space, with a lower level of risk, could be a good idea (see more ETFs in the Zacks ETF Center).
