According to daily Dziennik, U.S. secretary of state Condoleezza Rice discussed the issue with Secretary of Defense Robert Gates on Monday.
The U.S. is seriously considering placing a Patriot missile battery in Poland. In return it wants Poland's assurance that the missiles could be used at any other place any time, according to the report.
Poland is ready to accept such offer, according to earlier statements by Poland's defense and foreign ministers.
The United States plans to install a base for 10 interceptor missiles in northern Poland to protect the U.S. and Europe from possible future attacks from Iran. Talks later became bogged down over Polish demands for more military aid.
Warsaw has been lobbying Washington to provide a THAAD or Patriot-type air defense system in exchange for a Polish green light for hosting the silos.
Russia objects the anti-missile shield plan, saying it will threaten Russian national security. Moscow has warned that it will target its missiles at the system if it is deployed in Poland.
