The value of military hardware manufacturers has soared.
Global military spending rose 4% in 2008 to a record $1,464bn (£914bn) - up 45% since 1999, according to the Stockholm-based peace institute Sipri.
In contrast with civilian aerospace and airlines, the defence industry remains healthy.
"The global financial crisis has yet to have an impact on major arms companies' revenues, profits and order backlogs," Sipri said.
Peace-keeping operations - which also benefit defence firms - rose 11%.
Missions were launched in trouble spots such as Darfur and the Democratic Republic of the Congo.
"Another record was set, with the total of international peace operation personnel reaching 187,586," said Sipri, or Stockholm International Peace Research Institute.
As the world's aerospace and defence industry prepares for next week's Paris air show centenary, it seems much of the focus is set to shift away from troubled civilian aircraft makers, which are struggling with reduced orders from recession-hit airlines, towards the companies that make fighter jets and other military hardware.
The top 10 global arms producers
BAE Systems $29.9bn
Lockheed Martin $29.4bn
General Dynamics $21.5bn
EADS (West Europe) $13.1bn
L-3 Communications $11.2bn

In total, the 100 leading defence manufacturers sold arms worth $347bn during 2007, the most recent year for which reliable data are available.
Almost all the companies were American or European. Some 61% of the total was accounted for by 44 US companies, with 32 West European companies accounting for a further 31%. Other companies were Russian, Japanese, Israeli and Indian.
"Since 2002, the value of the top 100 arms sales has increased by 37% in real terms," Sipri said. "The US presidency of George W Bush... was a period of continuity in the arms industry. This followed a period of consolidation in the 1990s and early 2000s."
The US aerospace and defence giant Boeing remains the world's largest, with arms sales of $30.5bn during 2007. The UK's BAE Systems ranked a close second, with arms sales of $29.9bn, while Lockheed Martin was third with $29.4bn in sales.

The US remains the biggest spender, accounting for 58% of the total global spending increase during the decade, though China and Russia have reduced the gap.
Both tripled military spending over the decade, and Russia "is maintaining plans for further increases despite severe economic problems".
Military spending in the Middle East fell slightly during 2008, but Sipri saw this as a temporary drop. "Many countries in the region [are] planning major arms purchases," Sipri said.
One exception was Iraq, whose military budget rose 133% during 2008 when compared with 2007. "Iraq remains highly dependent on the US for ams supplies, with numerous orders planned," Sipri says.
US military spending accounted for 58% of the total global spending increase during the decade, with extra funds set aside to fight the "war on terror".
In addition, the wars in Afghanistan and Iraq cost the US $903bn.
"The idea of the 'war on terror' has encouraged many countries to see their problems through a highly militarised lens, using this to justify high military spending," said Sam Perlo-Freeman, head of the military expenditure project at Sipri, or Stockholm International Peace Research Institute.
High levels of military spending can cause economic difficulties for even the wealthiest of nations, Sipri insisted.
"During the eight-year presidency of George W Bush, US military expenditure increased to the highest level in real terms since World War Two," Sipri said.
"This increase has contributed to soaring budget deficits," the yearbook states, pointing to how both the Iraq and Afghanistan conflicts were funded "primarily through emergency supplemental appropriations outside the regular budgetary process", funded by borrowing.
"Arms companies may face reduced demand in the future if governments cut military spending in response to rising budget deficits," Sipri observed.
