22  Introduction  to hovercraft

                 In  the  1960s and  70s BHC  had  some  success in marketing  their  SR.N6  and  BH.7
              craft  for military  service, to  Saudi  Arabia,  Iraq  and  Iran. There  has  been  no  signifi-
              cant fleet development  to  follow  this.  The  British Navy  carried  out  trials  for  many
              years  [213] without  moving forward to integration  of  ACV and  SES technology  with
              its fleet. This  was partly  due  to  defence policy  in this period  which  concentrated  on
              projection of UK power to far flung colonies - the 'blue water' Navy - rather than  oper-
              ations  in  the  European  coastal  area.  Without  support  from  the  UK  government,  it
              was  difficult  for  British  ACV/SES  manufacturers  to  develop  and  market  suitable
              products  for sale abroad.  UK  companies  were therefore limited  to  what was possible
              in  a  self  resourced  commercial  environment.  The  utility  market  had  requirements
              which could  be met in this respect, and  the operational  support,  though  demanding,
              was not  on the  scale that  military customers  would  demand.
                In  the  SES market,  the  UK  shipbuilding  industry was already  in decline  from  the
              early  1960s, and  so development of  larger  SES vessels, which would  require  consider-
              able investment, was not  taken up. This opportunity  was taken up first by Bell Halter,
              and  latterly by shipyards in a number  of  other  countries.


                 1.3  ACV and    SES   development     in  the  former  USSR

              The former USSR  has carried  out  ACV and  SES research  since the beginning of  the
               1960s.  More  than  two  hundred  sidewall  passenger  hovercraft  have  been  built  since
              then,  and  over  two hundred  amphibious  ACVs  for military  missions  and  passenger
