Full-year pretax profit on an underlying basis fell to 30.3 million pounds from 51.6 million pounds a year earlier.

Revenue fell to 474.9 million pounds in the year ended Oct. 31, 2014 from 624.9 million pounds a year earlier.

Chemring, whose profit was hit by budgetary cuts in the United States, has been selling its non-core businesses since 2012 and pushing into non-NATO markets.

The company sold its European ammunitions business to France's state-owned Nexter Systems SA for about 168 million euros in April to focus on its core defence technology business.

"Whilst there has been growth in some markets, notably the Middle East, these regions are still modest in scale when compared to NATO defence spending," the company said in a results statement on Thursday.
