HMS “Illustrious” undertook a port visit to Merseyside from 22 to 27 October 2009 as part of naval regional engagement, following her participation in exercises off the north-west coast. This also provided the Royal Navy with an opportunity to bring this year's Fly Navy 100 celebrations to the north of the UK.
The cost of the visit was approximately £77,000, which was met by public funds. This sum includes costs associated with the ship's berthing; the conservancy and environmental fees; stewarding and security; and site costs (ie road closures, provision of toilets for members of the public visiting the static park, site management and barriers).
Separately, a reception was held onboard the ship on 23 October to mark the centenary of naval aviation. The cost of this was met by non-public sponsorship received by Fly Navy 100.
In addition, a Royal Marines Band concert, in aid of the Royal Navy and Royal Marines Charity, took place on 24 October. The marginal costs for this were funded by the charity.
