The USA has announced the first live-fire test of a Raytheon SM-3 missile from the land-based version of Lockheed Martin's Aegis missile defence system.
Lockheed said it was the first test of the Aegis system, which will be operational in Romania next year and is designed to protect US and Nato forces in Europe from a ballistic missile attack, using a land-based missile launcher.
The test, conducted at the Pacific Missile Range Facility (PMRF) in Hawaii late yesterday, saw the system detect, track and engage a simulated ballistic missile target using Raytheon's Standard Missile 3 Block IB, according to the US Missile Defence Agency and the companies.
"We're now one step closer to achieving an operational Aegis Ashore capability to combat missile defense threats to further protect our nation and allies," Brendan Scanlon, Lockheed's director of Aegis Ashore programs, said in a statement.
The test of the new missile defence system, which is already used on US warships around the world, comes amid growing interest in missile defence systems as tensions mount between Nato and Russia over its annexation of the Crimea region of Ukraine.
Raytheon said an intercept flight test of the system would follow next year. It said the ability to use the SM-3 missile at sea and on land would give military commanders more flexibility.
The land-based system uses the same SM-3 missile deployed on Aegis warships, and currently holds 24 SM-3 missiles at one time. The system can also be expanded to hold more launchers and missiles, Raytheon said.
"The SM-3 Block IB deployed for the first time earlier this year at sea, and the success of this Aegis Ashore test keeps us on track to deploy the missile on land in 2015," said Mitch Stevison, Raytheon's Standard Missile-3 senior director.
The Obama administration's European Phased Adaptive Approach calls for the first Aegis Ashore site to be operational in Romania in 2015, with a second site to follow in Poland in 2018.
Riki Ellison, founder of the non-profit Missile Defense Advocacy Alliance said the test meant Nato's missile defence shield, developed at a cost of around $800m (£475m), was becoming a reality. He said the Aegis missile defence system had achieved 28 successful test intercepts over the past 11 years.
"This system holds great promise for the future," Ellison said in a statement, noting that similar systems could be used around the world to deter threats from ballistic and cruise missile and even unmanned vehicles.
