Romania's Defense Ministry on November 10 welcomed the approval of the potential sale of 54 Abrams M1A2 SEPv3 tanks to Bucharest announced by the U.S. Defense Security Cooperation Agency (DSCA) a day earlier and the subsequent notification by U.S. Congress of the deal. The sale of the tanks, ammunition, and training simulators was estimated by the ministry at $1.07 billion, but Congress was notified of a higher value -- $2.5 billion -- by the DSCA. The reason for the difference in price was not immediately clear. NATO member Romania shares a 650-kilometer border with Ukraine.
