Swedish policymakers have made clear that they wish to update the air-defense system by 2020, and this tight deadline has narrowed down the options to two systems, which are already developed and widely in use.
The first is the Patriot, developed by U.S. defense giant Raytheon, and the second is French-Italian Eurosam’s SAMP/T. Both systems were employed in Aurora 17, and reports suggest that the Swedish government is very close to making a final decision on which one to choose – a process reportedly surrounded by intense lobbying from both the U.S. and European sides.
John R. Deni in War On The Rocks recommends a return to a more permanently forward-stationed army.
[With] specific regard to Europe, the Pentagon should aim to station these units in Poland, either in whole or in part through split-basing. Stationing in Poland would provide greater assurance to Eastern Europe and more effectively deter aggression. Most importantly from a fiscal perspective, the Polish government has evinced a willingness to share some of the costs of construction and base operations.
According to Deni there are pretty much only advantages to having forward-stationed troops instead of relying on a scheme of rotational deployment.
