Terrible headline.
It is not an Aegis destroyer, simply because it has an Aegis-like radar system.
Aegis-like could mean many things...it could mean they have a comparable yet inferior system or it could mean that they simply made a system that operates like the Aegis system - but it could be relative junk.
Yep, I agree that the headline is not technically accurate. Even if it was 100% Aegis capable it could still not be called Aegis ....just as sparkling wine is never Champagne unless it the grapes come from the Champagne region. However I think the mods require the header to be as it is in the original source, hence that is why it is as it is.
