yeah its pretty much the same as the daring
http://www.naval-technology.com/projects/horizon/
but the daring doesnt carry torps as it carries more missiles and room for more if needed, the daring also uses the mk8 4.5'' naval gun which uses the new HE shell for an effective range of 27.5km compared to the 76mm installed on the horizon that have an effective range of 16km and a lower damage rating. the 76's do have a much higher rate of fire though but they are pretty much useless for shore bombarding.
they also use different radar systems as the uk were concerned about the radar being blocked so the more versitile sampson radar is used on the 45
6 45's have been ordered with 8 the target by 2014.
