There is currently a drive to put more RN ships to sea, and this has involved big changes such as increasing the number of personnel. I presume that it will also involve buying more spares for ships' systems - so hopefully that will improve the situation with aircraft spares.
According to certain dark blue posters, such as those who see it up close and personal regularly, it is the spares issue that causes problems - ask
@wafubustard and
@alfred_the_great - but it is a very capable ASW system. Hopefully developments such as multi static sonar and the networking of sonar data will enhance that even more.
Others, perhaps assuming that the RN does ASW helicopter operations just like the USN, said we would be better off with a shorter legged aircraft because it would automatically have ample spares. A fighter with greater range can spend longer on CAP at a certain distance from the carrier, so surely it is a no brainer that the same is also true for a helicopter being employed as a task group asset?
