The Defense Security Cooperation Agency (DSCA) notified Congress of the foreign military sale on Thursday.

“This proposed sale will provide Canada with SM-2 Block IIIC missiles for installation on its planned 15 Canadian Surface Combatant (CSC) ships, ensuring its ability to operate alongside U.S. and Allied naval forces against the full spectrum of naval threats,” DSCA officials wrote in a statement.

Along with the Raytheon [RTN]-built missiles, Canada would also receive 100 MK13 vertical launch systems.
