The U.S. is sending a pair of nuclear-capable B-2 stealth bombers from their base in Missouri to England on a short-term mission in a show of support to U.S. allies overseas, according to the U.S. European command.

The $2 billion batwing aircraft are flying from Whiteman Air Force Base, Missouri to Royal Air Force Fairford, in the United Kingdom, in what a EUCOM statement described as “recurring bomber assurance and deterrence operations.”
