In December 2014, Wärtsilä announced that agreement had been reached to acquire MSI from NYSE-listed L-3 Communications Holdings Inc. Electrical and Automation (E&A) systems are of increasing importance since the operation of ships is becoming ever more sophisticated. Wärtsilä’s strong position in the development of technologies that enhance operational efficiency will be further strengthened with the addition of MSI’s broad range of capabilities. The acquisition was finalised June 2015.
