The Air Force and Boeing recently signed a contract worth more than $674 million in order to help Boeing maintain its required infrastructure.

After a slowdown in the commercial satellite market, it wasn't certain that Boeing would be able to provide the support that Vandenberg Air Force Base and other bases desired.

Specifically, the money will go toward basic necessities, such as buildings, employees, and launch sites.

In return, the Air Force will receive support for three missions per year from Cape Canaveral Air Force Station in Florida and one mission per year from the local Vandenberg Air Force Base.

"We now have the basic contract structure in place to provide the government's required level of mission assurance with both Boeing and Lockheed Martin, and we will have the assured access to space needed for national security," Col. Joseph F. Boyle, Launch and Range Systems Wing chief engineer, said in a statement.

Lockheed Martin entered a similar contract in March, valued at $815 million.

The contract comes under the Air Force's Evolved Expendable Launch Vehicle program, which is a partnership between industry and government.
