Our friend Topol-M picked up an interesting intercept about an USAF B-2A Atlantic round robin mission on 13 Sep 2013. Thank you for sharing that with the rest of us.
On the 13th, two B2As transited the Atlantic in a round-robin mission, supported by four KC-135Rs, two this side of the European ocean (SPUR57 and SPUR58) and two on the US side (ETHYL 1 and 2). Also involved was E6B 164387 operating from Stuttgart, using an ATC call sign of RAZZ02.
Once things cleared up a bit the following was noted:
11175.0 kHz USB - HFGCS
