Because of the marked increase in capabilities delivered by the Type 45 destroyers in relation to their predecessors, the exceptionally high price per ship, and the large amount of public attention they have attracted, defence analysts and correspondents commonly refer to the "Daring" class as being the "most advanced" or "most powerful" air-defence destroyers in the world. Likewise, the ships' builders BAE Systems claim: "Able to detect and track hundreds of targets simultaneously, the Type 45 Destroyer is recognised as the most advanced anti-air warfare vessel in the world." Nick Brown, the editor-in-chief of Jane's International Defence Review, was quoted by "The Huffington Post" (a US online news aggregator and blog) saying, "It's 45 destroyer certainly one of the most advanced air defence ships in the world... The US Aegis system is similar, but Sea Viper is more advanced."
