LOCH Class Anti-Submarine Frigate ordered on
25th January 1943 from W. Pickersgill of Sunderland
and to be named LOCH KILBIRNIE. Orders were placed with several other shipyards
for this Class of Frigate at the same time. However in late 1943 the contract
was changed for construction of a new design of Anti-Aircraft Frigate
(BAY Class - See General Information). The ship was laid down on
23rd October 1944 and was launched as HMS MOUNTS BAY on 8th June 1945. No
previous RN warship had borne this name. Work was suspended in 1946 and a new
contract to complete her build was placed with John I Thornycroft.
The ship was transferred to Woolston, Southampton on
20th March 1946. Her build was completed on 11th April 1949.

HMS MOUNTS BAY continued her
record of service on foreign stations after being re-commissioned
in 1955 and again in 1957, both in
the West Indies and South Atlantic. Her final commission was for further
service in the Far East. On return to Portsmouth in May 1960 the ship was
placed in Reserve and not re-commissioned as planned. Placed on the
Disposal List in 1961 she was sold to Portugal and renamed VASCO DA GAMA.
Before Portuguese Navy service she
was modernised at Woolston by John I Thornycroft. The ship remained on the Active List until 1971 when
sold for demolition.
