Finland purchases Israeli David's Sling air-defense system for added security.

Finland has become the first country to purchase Israel's David's Sling air-defense system, which defends against medium- and long-range aerial threats. The system will significantly extend the range of Finland's ground-based air defenses, according to the Finnish Defense Ministry. The deal is valued at nearly $345 million and is subject to approval by the US. Finland officially became NATO's 31st member on Tuesday, bringing a significant firepower boost to the military alliance.
