Missile Defense Agency Director Vice Adm. James Syring, during a presentation last week at the annual Space and Missile Defense Symposium in Huntsville, AL, touched on the deployment of a second AN/TPY-2 radar to Japan.
According to the presentation slides he used, a second radar system in that country "enhances [the] defense of Japan, U.S. forward deployed forces, and the U.S. homeland from North Korean ballistic missiles" and "bolsters regional security allowing flexibility in deploying Aegis [Ballistic Missile Defense] ships."
A "Technical Capability Declaration" (TCD) is expected within one year after the U.S. is granted access to the proposed site, discussions between the two countries on which "are ongoing," according to the slides.
MDA spokesman Rick Lehner told Inside Missile Defense this week that TCD "is declared by MDA and is system-focused." It differs from the initial operational capability designation in that "IOC is declared by the warfighter and is broader in scope than TCD, i.e. it includes the warfighting organization's ability to employ and maintain the system."
The United States has five forward-based AN/TPY-2 radars that are operational. Four are being used in Northern Japan, Israel, Turkey and within the U.S. Central Command area of operation and one is used for testing. Once the fifth radar is deployed to Japan, a forward-based radar would not be available for testing purposes. The fifth radar was available for MDA's large-scale test in the Kwajalein Atoll in October 2012. Another MDA test of a similar caliber is scheduled for later this year.
According to Syring's briefing slides, that test -- designated FTO-01 -- is "on track" for the fourth quarter of fiscal year 2013. Its purpose is to "demonstrate regional-theater [Ballistic Missile Defense System] ability to defeat, in a layered architecture, a raid of two threat-representative medium range ballistic missiles, each flying challenging and realistic attack profiles."
The Aegis BMD system will attempt to intercept the first MRBM, while the Terminal High-Altitude Area Defense system will try to shoot down the second MRBM, and could engage the first target if needed, according to the presentation.
Inside the Army reported in July that in order to have a forward-based AN/TPY-2 radar available for future tests once a fifth radar deploys to Japan, the Army plans to borrow a radar from an existing THAAD battery or grab a radar intended for THAAD as it comes off of Raytheon's production line, according to Lehner.
"We will have a TPY-2 available for future tests after Japan deployment, with either a radar coming off the production line prior to deployment to a future THAAD battery, or a radar from an existing THAAD battery will be requested," Lehner told ITA in a July 17 statement.
The Army intends to procure a total of 12 AN/TPY-2 radars -- six forward-based radars and six radars for THAAD batteries, ITA reported, adding:
Because building an AN/TPY-2 radar takes around 30 months, the next forward-based version would not roll off the production line for at least 36 months. According to Raytheon's missile defense and space programs' director, Jim Bedingfield, the 12th AN/TPY-2 radar the company will build -- intended to be forward-based -- is not on contract yet. The contract is expected to be cemented in September or October this year, he said.
Radars meant for THAAD batteries will be completed before that time. Raytheon and the Army signed contracts for the ninth and 10th radars in December 2011. The 11th radar's contract was finalized in December 2012 and is also in production.
The Army deployed its first THAAD battery to Guam in April, has a second battery standing by at Ft. Bliss, TX, and is working to stand up a third. Radars nine, 10 and 11 will go to THAAD batteries four, five and six.
While Raytheon supports the need to deploy a second radar to Japan, Bedingfield told ITA in a July 15 interview, "testing is extremely important to us on many levels both as a nation from our national security strategy down to proving our system works and down to the operating level where you must have proper tactics, techniques and procedures. The question is not whether the agency will continue a robust testing regimen, they will and they have told us they will and we stand ready to test with them. We want to test, we like to test, nobody does everything perfectly, we have to learn from our tests both when we succeed and when we fail."
Bedingfield said the real question is "how much will testing without some sort of dedicated asset to test in a very robust testing scheme, how will that affect our nation's ability to deploy, for example, a THAAD battery to Guam. These are obviously weighted questions that the government wrestles with in a tough budget time."
