In early 1941, the Royal Navy made provisions for
seaplane flying training at Lawrenny Ferry.
764 Seaplane Training Squadron used the facilities, which included a main
hangar, three concrete aircraft pens, an
slipway and
fuel storage, before moving permanently from
RAF Pembroke Dock. Accommodation consisted of two
Nissen huts, however, officers and petty officers were housed at Lawrenny Castle, while the Lawrenny Arms
pub acted as the
NCOs'
mess. Two
steam yachts, named
Carmela and
Zaza, also provided accommodation for squadron personnel. The base officially became a Royal Naval Air Station under the control of
RNAS Lee-on-Solent (HMS Daedalus) and played a key role in Seaplane Flying Training Part II, which included Seaplane conversion and gunnery courses. RNAS Lawrenny Ferry was commissioned as
Daedalus II on 1 February 1942. However, with the decline in training demand, the base was reduced to Care and Maintenance status in November 1943, with only three months’ notice required to re-commission and resume flying. The nissen huts and hangar were demolished in 1945, though the base remained listed in the April 1946 Navy List. == Royal Navy operations ==
