The West's dominance in providing military hardware around the world is set to erode, according to analysts in the sector.

In a white paper issued in May by consulting firm Avascent, 59 percent of global defense sales in 2015 came from Western countries with the United States accounting for the bulk of that figure.

But the same report suggested this dominance is on the wane and Avascent Managing Director Doug Berenson thinks he knows why.

"There are a growing number of countries that have a more sophisticated defense capability," he told CNBC by phone on Friday.

"They are more able to satisfy their own defense requirements and are starting to compete in the export market against more established suppliers."

Berenson said some development in this area has come from countries who have worked as partners with traditional suppliers such as the United States.

"Countries will buy a design from the U.S. or others, but they will do so on the condition that it can carry out final assembly or ensure significant local input," he added.
