Exercise Baltic Operations (BALTOPS) 2018 recently concluded and was pretty wide in scope, blending both NATO forces and non-aligned Baltic nations (i.e. Sweden and Finland) with 43 maritime units, more than 60 aircraft and a combined amphibious landing force (the latter of which included such nontypical units as the Sig 550-armed Romanian 307th Naval Infantry Regiment operating CRRC inflatables from a U.S. landing dock)
For instance:
They practiced some good, very relevant stuff to include mine/countermine ops, defense against fast attack craft, TRAP ops, and air defense exercise from shore-based low-flying fast jets (German Tornados).
One of the most eye-catching of the exercise footnotes was a photoex with 30 vessels to include the U.S. Navy’s Arleigh Burke-class destroyer USS Bainbridge (DDG 96), the Blue Ridge-class command and control ship USS Mount Whitney (LCC 20), and the Harpers Ferry-class dock landing ship USS Oak Hill (LSD 51). These were joined by the Finnish Hmeenmaa-class minelayer FNS Uusimaa (05), Denmark’s Iver Huitfeldt-class frigate HDMS Niels Juel (F363), the German Type 702 Berlin-class replenishment ship FGS Frankfurt A.M. (A1412), the RN’s Duke-class Type 23 frigate HMS Monmouth (F235) and a cornucopia of smaller patrol boats and mine countermeasure ships from such diverse players as Turkey and Lithuania.
