The National Interest:
The U.S. Navy and numerous NATO partners are firing a new, high-tech ship defense weapon that can identify, track and attack maneuvering anti-ship missiles with an active seeker enabling the missile to change course in flight, service officials said.
The Evolved Sea Sparrow Missile Block II, or ESSM, is a new version of an existing Sea Sparrow weapons system currently protecting aircraft carriers, destroyers, cruisers, amphibious assault ships and other vessels against anti-ship missiles and other surface and airborne short-range threats to ships.
The recent live-fire test follows the successful completion of two Controlled Test Vehicle flight tests in June 2017 and is the first in a series of live fire tests that will lead to the ESSM Block 2 missile entering production, Naval Sea Systems Command spokesman Alan Baribeau told Warrior Maven.
