Following a re-organization in 2007, Tyco International split into two new companies; one of these was Tyco Electronics, which included the cable division. In 2011 the new company was renamed TE Connectivity of which TE Subsea Communications was a division. Consequently, “Tyco” was dropped from the ship names. The company subsequently became TE SubCom, and is now SubCom.

In 2015 CS Resolute laid a new Atlantic cable for Hibernia Networks, Hibernia Express, and in October 2017 the company completed the Marea cable from the USA to Spain.
