The Obama administration is proposing an 11 percent budget increase in 2011 for the Homeland Security Department. The $43.6 billion request includes increases for airport security, Coast Guard ships and a new headquarters.

The Transportation Security Administration would get one of the largest percentage increases: a 12 percent increase from $5.1 billion this year to $5.7 billion. More than $700 million of that budget will pay for 1,000 new advanced screening machines at airport checkpoints. Peggy Sherry, the department's acting chief financial officer, told reporters the budget also includes $219 million for personnel to operate those machines. Another $54 million would modernize transportation security credentials.

Customs and Border Protection would see a modest decrease — from $10.1 billion to $9.8 billion — but DHS Secretary Janet Napolitano says the agency still plans to hire 300 new customs officers.

Nearly $1 billion from the Coast Guard budget is earmarked for new ships: $538 million would pay for a fifth National Security Cutter, and $240 million would build four Fast Response Cutters.

The DHS budget also includes $4 billion in grants for state and local governments, most of it disbursed through the Federal Emergency Management Agency.

The E-Verify employment eligibility system would get $103 million under the request; the SBInet "virtual fence" along the southern border would get $574 million, down sharply from $800 million last year.

The budget includes $1.6 billion for departmental management — including $288 million for the new consolidated DHS headquarters at the St. Elizabeth's campus in Southeast Washington.
