Less than a year after terminating the Expeditionary Fighting Vehicle program for runaway costs, the Pentagon has formally launched a replacement acquisition effort to develop an Amphibious Combat Vehicle -- a pared-down successor in terms of capability and cost the Marine Corps hopes will begin ferrying troops from ship to shore as soon as 2022.

Pentagon top brass have formally reaffirmed a 2009 pact outlining a framework for how the Air Force will provide direct support to the Army for the delivery of time-sensitive, mission-critical equipment, a move designed to "mitigate" the Defense Department's decision to eliminate the C-27J Joint Cargo Aircraft fleet as part of a package of budget-reduction measures.

The Navy's new budget plan will reverse a move announced last year to accelerate the production of a new fleet of oilers, a decision that strips three of four vessels from the service's earlier plan and resets the start date for construction of the new logistics ship to fiscal year 2017, according to sources familiar with the Pentagon's new budget plan.

The Pentagon's next Quadrennial Defense Review will be shaped largely by how Congress grapples with the federal debt and who wins the White House in 2012, Under Secretary of Defense for Policy Michèle Flournoy said today.

The Army is reevaluating plans to build a facility for the Joint Land Attack Cruise Missile Defense Elevated Netted Sensor aerostat system at Ft.

For its "new afloat forward staging base," the Defense Department will overhaul one of three Mobile Landing Platforms -- ships long a part of the Navy's modernization blueprint -- to meet a "longstanding" U.S. Central Command need, according to officials familiar with Navy plans.
