The Wall Street Journal reports: Israel on Wednesday said it plans to expand a key missile-defense system to warships, in a bid to protect the country’s lucrative offshore gas fields amid growing aerial threats from regional adversaries.

Israel’s military said it had successfully tested a naval version of its land-based Iron Dome system in recent weeks and would begin deploying it on its newest frigates to protect the country’s strategic assets, including its gas rigs.

The naval system is a combination of the land-based Iron Dome missile interceptor and radar systems on ships, the military said. “We call it the Iron Dome of the sea,” Col. Ariel Shir, head of operational systems in the Israeli navy, told reporters on a phone call.

Israel’s land-based Iron Dome missile defense system intercepts short-range rockets and has become a bedrock of the country’s defense since its introduction in 2011.
