Alexander Fomin, head of the Federal Service for Military and Technical Cooperation, said the country had also booked international orders worth $46 billion, most of which will be filled in the next three or four years.
"In the first month of this year, we sold arms worth $1 billion. In the first two months, total weapons sales exceeded $2.5 billion," Fomin told Ekho Moskvy radio.
Fomin said Moscow and Iraq were still negotiating a deal valued at $4.2 billion.
A lucrative sale of anti-aircraft missiles to Iran was called off, leading to a $4 billion lawsuit filed by the Iranians, Russia's RIA Novosti news agency said.
Fomin said Russia was stuck with the unsold S-300 missiles, which he said were custom made for the Iranians and difficult to sell to another country.
