Defence Minister Kristóf Szalay-Bobrovniczky said the complex would be of "great importance" not just for Hungary but for all of Europe. The complex will create 1,000-1,200 jobs, he added.

European Commissioner for Internal Market Thierry Breton said there would be "strong demand" for the munitions produced at the facility as member states replenished their inventories.

He acknowledged that Hungary's spending on defense now exceeded 2% of GDP.
