1628. After the Duke was assassinated in 1632, she was taken into the Royal Navy and then converted into a chain ship for the Chatham "barricado" c. 1641. She was sent to Harwich as a careening hulk in August 1650, and then drops out of the historical record. Lion's Whelp may be the hulk at Harwich that was ordered to be sold in October 1651. The second Lion's Whelp was also built by William Castell of St. Savior's in Southwark. She was converted into a chain ship for the Chatham 'barricado' c.1641, then was ordered to be sold in August, 1650 together with the Defiance and Merhonour as having become too decayed, even to be a careening hulk at Harwich. The third Lion's Whelp was built by John Dearsley of Ipswich at Wapping. She was listed as unfit for service in Batten's survey of 1647 and 'cast' before February, 1643. The fourth Lion's Whelp was built by Christopher Malim of Redriff. She was used for experimental constructions in the Project Dutchman, c.1633. These works in the hold were ordered for removal in March 1643 because they were of no use in a man-o-war. Details of the experimental constructions are lacking, although Warrell's research points to Cornelius Drebbel as having executed the removal order. The fourth Lion's Whelp struck a rock in St. Aubrey's Bay, Jersey on 4 August 1636 and sank without any loss of life. The fifth Lion's Whelp was built by Peter Marsh of Wapping and spent most of her life in service in Ireland. She foundered in the North Sea on 28 June 1637 and sank with the loss of 17 men. Cause of this tragedy was placed with the shipyard who built her of 'mean, sappy timbers'. The sixth Lion's Whelp was built by Peter Pett of Ratcliffe. Peter Pett (1610-?1672) was an English Master Shipwright, the second Resident Commissioner of the Chatham Dockyard. Phinaes Pett was viewed as the greatest shipbuilder of his time, indeed perhaps the finest to have ever lived and worked in England. The reputation of the Pett dynasty ensured that the sixth Lion's Whelp was designed and constructed to the highest standards. Her captain was John Pett (1601/2 – 1628), the eldest son of Phineas Pett who died when the ship went down off the coast of Brittany when returning from the La Rochelle expedition in 1628.
