NNS Bonny is the former HMS Gifford, one of 23 boats of the Ford class of patrol boats built for the Royal Navy in the 1950s.
The names of the class ships were all chosen from villages ending in "-ford". This boat was named after Gifford.
Gifford was launched on 30 June 1954. In 1968 the vessel was sold to Nigeria and renamed NNS Bonny. Bonny took part in the Nigerian Civil War and was decommissioned in 1983. Bonny is preserved at the Nigerian War Museum in Umuahia.
