TEL AVIV, Israel โ€” Competitive tension is mounting as aerospace firms finalize bids for the first two procurements of a planned four-phase U.S. target and countermeasures acquisition program estimated at nearly $5 billion over the next five years.

The Pentagonโ€™s Missile Defense Agency (MDA) is budgeting $4.9 billion through 2015 as part of a comprehensive revamping of its Ballistic Missile Defense Test and Targets program. The agency is asking Congress for $1.1 billion of that sum in the coming year for acquisition and support programs, beginning with targets designed to simulate medium- and intermediate-range ballistic missiles.

Proposals are due in July for targets simulating medium-range ballistic missiles, with ranges from 1,000 kilometers to 3,000 kilometers. By August, defense and industry sources say, proposals are due for candidate targets meeting performance parameters of intermediate-range missiles, with ranges from 3,000 kilometers to 5,000 kilometers.

According to an MDA 2011 budget estimate document dated Jan. 15, the agency aims to down-select to a single contractor in each target class, with initial awards planned for early 2011 to support flight testing by 2012.

In addition to the roughly $517 million being requested in 2011 to acquire new targets, MDA hopes to spend an even larger sum โ€” about $559 million โ€” to support system level flight tests.[spacenews-ad]

The planned acquisition effort follows more than a year of intensive study and the crafting of an integrated master plan aimed at providing an extensive, cost-effective inventory of highly reliable targets in support of MDAโ€™s overall test plan, defense and industry sources say. According to MDAโ€™s budget request, the agency plans to conduct 120 test events from 2011 through 2015.

The planned near-term buys aim to transition from older, costly and less-reliable legacy systems to a new generation of targets. For example, the most recent planned test of the Terminal High Altitude Area Defense (THAAD) system was foiled when a short-range target missile supplied by Coleman Research Corp. failed to ignite after being dropped from its C-17 carrier aircraft. As a result of the December 2009 glitch, MDA imposed a freeze on the use of that particular target and directed Coleman  to submit a corrective action plan before the end of the year.

MDA spokesman Richard Lehner said tests involving the air-launched target could resume by early to mid-2011, pending the agencyโ€™s review of the corrective action plan.

Defense and industry sources say the next THAAD test is slated to occur in the next few weeks, this time against a medium-range ground-launched target.

โ€œIn the past, we relied on older targets based on retired missile technology, which was quite expensive to maintain and configure for missile defense,โ€ Lehner said. โ€œItโ€™s always been a challenge to have enough of an inventory of representative targets to meet our needs, and this long-term acquisition program will allow us to plan and test much more efficiently for the next 10 years or so.โ€

In a June 11 interview, Lehner said requests for industry proposals on short-range and intercontinental ballistic missile (ICBM)-class targets have not yet been released. At the moment, MDA is not suffering from a dearth of short-range targets of various types, he said, adding that the ICBM-class testing program, while important, will require more time to ensure that the targets meet the long-term requirements of the integrated master plan.

โ€œFor the immediate term, we need to focus on targets in support of our highest-priority programs. But ultimately, the aim is to refresh inventories for all four classes of ballistic missile threats,โ€ Lehner said.

Nearly a dozen firms plan to compete for one or more elements of the MDA target acquisition, modeling and test support program, among them: Boeing Co. of Chicago, Lockheed Martin Corp. of Bethesda, Md., Northrop Grumman Corp. of Los Angeles, Orbital Sciences Corp. of Dulles, Va., and Raytheon Co. of Waltham, Mass.

โ€œThe market for targets and testing support of MDA assets is considerable, and Northrop Grumman certainly plans to be a part of it,โ€ said Karen Williams, vice president for air and missile defense systems at the McLean, Va.-based Northrop Grumman Information Services. In a recent press briefing, Williams said Northrop Grumman aims to compete for the intermediate-range target program, and to leverage its ongoing modeling and simulation activity for the U.S. Army in support of other MDA needs.

โ€œLockheed Martin is committed to supporting the needs of MDAโ€™s targets and countermeasures program,โ€ said Lynn Fisher, spokeswoman for Lockheed Martin Space Systems Co. of Sunnyvale, Calif. She noted that Lockheed Martin provides about a quarter of MDAโ€™s targets of various ranges, launched from the ground, sea and air, and that since 1996, the company has had a reliability rate of 99 percent.

Karleen Seybold, program manager for Sparrow Targets at Tucson, Ariz.,-based Raytheon Missile Systems, said that firm not only is a candidate to supply the intermediate-range targets but also is prepared to propose an air-launched missile developed by Rafael of Israel for the short-range target procurement once that request for proposals is released.

โ€œRaytheonโ€™s approach is to look at current MDA investments and to leverage technologies for very high reliability,โ€ Seybold said in a June 10 interview. โ€œWe aim to leverage proven, cost-effective, operationally representative technologies in both of those categories.โ€
