Israel's military exports totaled $7.5 billion for 2018, down 18% from 2017, the Defense Ministry reported Wednesday.
The ministry said on Wednesday that despite the drop, the 2018 figures were a "major success" and the second-highest level in the past decade.
It said the $9.2 billion of defense exports in 2017 were "out of the ordinary" but was unable to explain the drop in 2018, saying only that the global market is "dynamic."
The largest share of Israel's exports consisted of missiles and air defense systems. Unmanned aerial vehicles, radar systems and ammunition also represented crucial exports.
Nearly half of Israel's sales went to Asia and the Pacific region.
Israel is the world's eighth-largest arms exporter, according to the Stockholm International Peace Research Institute.
