Several U.S. lawmakers, citing new but unspecified intelligence, urged Defense Secretary Leon Panetta to re-emphasize defending U.S. territory against long-range ballistic missile attacks.

In a Nov. 17 letter, House Armed Services strategic forces subcommittee Chairman Rep. Michael R. Turner (R-Ohio) and several colleagues also said they were informed that President Barack Obamaโ€™s administration is ready to abandon development of the Standard Missile (SM)-3 Block 2B interceptor.

The missile, the latest of three planned upgrades to the ship-based SM-3, was marked for  cancellation by the Senate Appropriations Committee in its version of the 2012 defense spending bill. The MDA requested $123.5 million for the program.

Rick Lehner, a Missile Defense Agency (MDA) spokesman,  declined via email to comment on the letter or on the White Houseโ€™s forthcoming 2013 budget request.

In their letter, the lawmakers said new intelligence indicates countries are developing long-range ballistic missiles that could potentially attack the United States. โ€œWe believe this new intelligence reiterates the need for the Administration to correct its priorities regarding missile defense, which should have, first and foremost, the missile defense of the homeland,โ€ the letter said.

The lawmakers criticized the White House for scaling back deployment of long-range missile interceptors on U.S. territory and canceling plans to deploy similar interceptors in Europe. Obamaโ€™s plan for defending Europe relies on the shorter-range SM-3, although longer-range and land-based variants of that interceptor are in development.

The House Armed Services Committee has been pressing the Pentagon for a โ€œhedging strategyโ€ for homeland defense but has yet to receive a strategy, the letter said. The lawmakers asked the White House for a briefing on the hedging strategy by Dec. 31 and said funding to counter long-range missile threats be increased in the MDAโ€™s 2013 budget request.
