UPDATE tbl SET col=REPLACE(col, 'US-Complete', 'US Complete');

If there are spaces in front and back, perhaps you should add some extra 
insurance to avoid changing 'US-Completely' or 'BUS-Complete' as well:

UPDATE tbl SET col=REPLACE(col, ' US-Complete ', ' US Complete ');

The best insurance is to do a SELECT first to see what will be changed:

SELECT col, REPLACE(col, 'US-Complete', 'US Complete') FROM tbl;
