Editing County-class destroyer (section)

===Possible development===
It was suggested by [[Vosper Thornycroft]] that the Counties could have been developed for the anti-submarine role by replacing the Seaslug system with a larger hangar and flight deck and the possibility of removing Seaslug and rebuilding the missile tunnel as storage for extra [[Westland Lynx]] helicopters.{{sfnp|Preston|1980}}{{page needed|date=September 2018}} Certainly, these arrangements as originally installed to operate a single [[Westland Wessex]] anti-submarine helicopter were problematic, with a hangar so cramped it took an hour to get the aircraft either in or out again, during which the port Seacat launcher was unusable. However it was determined that beam-restrictions would still limit the Counties' helicopter operation in RN service to the obsolescent Wessex, as they were too narrow to handle the far more capable [[Westland Sea King|British-built Sea King HAS]]. The Chilean navy, however, did convert two of the four ships they purchased along these lines.{{citation needed|date=December 2014}}
