Unannounced Deals:

• Patriot PAC-3 Missiles— about $5.6 billion;
• CH-47 Chinook helicopters— about $1.32 billion.

The State Department is not required to announce the sale to the public under the rules governing U.S. arms exports, which use different modalities for different types of sales.

The sales were not announced publicly because they expanded previously agreed arms deals.
