Yeah, lets scrap the lot. Why not.
I do wish when glibly slagging off the new Type 45 for cost and PAAMS for range, you'd bother to write more exhaustively on the systems as a whole rather than focussing on whichever bit got your goat.
The escort air defence role (of which the Type 45 is ideally suited) whether as part of a self defence exercise or a co-ordinated anti-air bubble around, for example, a carrier or other capital ship, requires that you engage multiple high speed low level targets often tracked on multiple vectors - and every second counts.
PAAMS is perfect for this; a range of 75m using the Aster 30 missile is massive and when you consider the rate of fire (8 missiles in about 10 seconds), that is a significant response to an incoming threat. It is most definitely a quantum leap beyond current capabilities and of course fits the NATO standard, and will undoubtedly have further capabilities added to it in future generations of the same system.
When considering how much air space it dominates, it is too simplistic to simply focus on a single PAAMS system in terms of individual missile range. The PAAMS radar and guidance system goes out much further than the missile itself, and an integrated air defence picture with more than one PAAMS equipped ship (Type 45 or otherwise) will easily give you the air space domination mentioned.
The Royal Navy has quietly got on with refitting (at enormous expense) existing surface units over the last 20-30 years, however refitting only gets you so far - both in terms of capabilities and of course cost effectiveness. It is about time we (and we are an island in need of an independent naval capability, hence why we're in a different place with different needs than Switzerland) invested in the Royal Navy and ensured they were given the tools required to achieve those objectives that will be set for them over the next 20-30 years.
Comparing the cost per unit on a like for like basis with the Army, based on the fact it is well publicised that our chaps over in Afghanistan and Iraq are finding themselves short is ridiculous. The Navy maintains much lower numbers of operational units but which operate in completely different circumstances and therefore have different needs - the Army on the other hand has considerably more yet lower per-unit cost assets.
This is a stupid article, based in part on reading BBC News and in part reading crap from Wikipedia - or at least, thats how it appears. Sort it out eh?
