HMS Hampshire was a 50-gun fourth rate ship of the line of the Royal Navy, built to the 1733 proposals of the 1719 Establishment dimensions at Ipswich, and launched on 13 November 1741. On 29 March 1742 she was under the command of Captain Thomas Limeburner when she captured Galgo, a Spanish privateer sloop of 12 guns and 12 patereros (swivel guns). She had a crew of 140 men, some of whom were English. She was a new vessel, only 14 months old, belonging to San Sebastián, and had taken 21 prizes. The Royal Navy apparently briefly took Galgo into service under her existing name.
