HMS Assurance (1646)

HMS Assurance was a 32-gun fourth rate frigate of the English Royal Navy, built by Peter Pett I at Deptford Dockyard and launched in 1646. The term 'frigate' during the period of this ship referred to a method of construction, rather than a role which did not develop until the following century.

Samuel Pepys states in his diary that Assurance sank near Woolwich during a storm in December of 1660, with the loss of twenty men. He visited the site a few days later. The ship was subsequently refloated by 17 December.

In August 1666, Assurance participated in the raid on a large Dutch merchant fleet in the Vlie estuary that became known as Holmes's Bonfire. By 1667, Assurance's armament had been increased to 40 guns.

Assurance was sold out of the navy in 1698.
