Yeah there's been heaps of media buzz about the Type 45's propulsion woes. Put that down to being relatively novel and experiencing issues. Ford class carriers have had its share of detractors too.
On second viewing of the Aster 15 and 30 missiles, it seems the European destroyers are well outranged by Russian, Chinese, and US SAM ranges. But they are all more or less proportional to size and weight. The ESSM stands out though. USN and PLAN surface to air missiles seem to have similar reach, not counting ABM like SM-3 and HQ-19 and HQ-29 (or whatever the different types are called). PLAN's HHQ-16 at 70km range for its size is slightly underwhelming compared to the ESSM. Not sure if HHQ-16 is quad packable into PLAN's universal VLS.
