Exhibit 99.1

FOR IMMEDIATE RELEASE

DynCorp International Inc. Updates
Guidance for Fiscal Year Ending March 30, 2007

Falls Church, VA — October 4, 2006 — DynCorp International Inc. (the “Company”) (NYSE: DCP) has revised full-year revenue guidance down from $2.4 billion to a range of $2.1 to $2.2 billion for the fiscal year ending March 30, 2007.  This estimate is based on current backlog and management’s estimate of future contract awards.

For the second quarter, which ended September 29, 2006, the Company will recognize one-time charges of approximately $18 million related to three events: a $5 million of severance expense as a result of the departure of senior executives; a charge of $5 million to finish construction for a camp in Iraq for the Department of State; and $8 million related to a security contract for a customer in Saudi Arabia.

As a result of continuing cost reductions and strong program performance, the one-time charges will be offset during the balance of the year.  Earnings before interest, taxes, depreciation and amortization (EBITDA) guidance for the full year remains unchanged at $163.6 million, and Earnings per share (“EPS”) guidance also is unchanged at $0.47 per share.

Full year adjusted EBITDA also remains unchanged at $170.0 million, along with pro forma diluted EPS at $0.71 and diluted cash EPS at $1.48.

Herb Lanese, the Company’s President and CEO, said, “I’m very pleased with the company’s cost reduction and streamlining efforts.  These efforts not only enhance performance on current contracts, but also improve our competitiveness.”
