(CNN)The global arms industry continues to grow with total sales up 4.6% last year, according to data from the Stockholm International Peace Research Institute (SIPRI) released Monday.
Global weapons sales up as US manufacturers dominate world market
The top 100 weapons companies sold $420 billion in arms and military services in 2018, and the top five companies are all from the United States, said SIPRI in a statement.
Lockheed Martin, Boeing, Northrop Grumman, Raytheon and General Dynamics made $148 billion in sales, equivalent to 35% of the total. Overall, US companies account for 59% of total sales.
Global arms sales by companies listed in SIPRI's top 100 have grown by 47% since 2002, when the SIPRI database was started. It does not include Chinese arms companies due to a lack of reliable data.
Sales by Russian companies remained stable year-on-year, with $36.2 billion total sales or 8.6% of the global total. The country's largest arms producer -- Almaz-Antey -- recorded growth of 18%.
"This increase was due not only to strong domestic demand, but also to continued growth in sales to other countries, particularly of the S-400 air defense system," said Alexandra Kuimova, Researcher for SIPRI's Arms and Military Expenditure Programme.
Britain remains the biggest producer of weapons in Europe, but sales by British companies dropped 4.8% to $35.1 billion.
France is the second-largest producer in Europe, with $23.2 billion in sales. Overall growth was driven by a sharp increase in sales at Dassault Aviation Groupe, which jumped 30% for the year to $2.9 billion. Sales by German arms producers fell by 3.8% to $8.4 billion.
The US weapons industry saw significant consolidation in 2018 as companies look to benefit from President Donald Trump's desire to overhaul the military.
"US companies are preparing for the new arms modernization program that was announced in 2017 by President Trump," said Aude Fleurant, Director of SIPRI's Arms and Military Expenditure Programme, in a statement.
"Large US companies are merging to be able to produce the new generation of weapon systems and therefore be in a better position to win contracts from the US Government."
