Israel’s Arrow defence systems helped thwart Iran’s massive missile and drone attack last month and a number of countries are now interested in purchasing the technology, Reuters reports quoting the developer’s chief executive.

Iran’s overnight attack between April 13 and 14, repelled by Israel’s multi-tiered defence shield with the help from allies, included more than 100 ballistic missiles.

The Arrow system, according to Israel’s air force, “carried out the main part” of their interception. That success immediately drummed up global interest, said Boaz Levy, CEO of state-owned Israel Aerospace Industries (IAI), the project’s main contractor.

The US is a partner in the Arrow project and Boeing is involved in its production.

“A number of countries have approached us asking for information,” Levy told Reuters. “I’m very optimistic that there will be more deals for the Arrow system, especially after the very special demonstration we did.”

He declined to name any of the countries since talks are in the early stages.
