Lockheed Martin has won a contract to build 4 frigates for Saudi Arabia for $2 billion:

The Navy announced Friday that Lockheed Martin was awarded a $1.96 billion contract to build four multi-mission surface combatants for Saudi Arabia.

The ships, which are slated to be built at Fincantieri's Marinette Marine shipyard in Wisconsin, are derived from the Freedom-class Littoral Combat Ship design.

The contract announcement was posted on the Defense Department's website Friday night.

"The awarded contract includes associated cost-plus-fixed-fee class design and related material and firm-fixed-price integrated data environment," the announcement said.

That is $0.5 billion per a 4,000-ton frigate.
