On the following June 15 , the $ 3 authorized the acquisition of two ships for the purpose of defending the colony ' s trade .

Early establishment and legislative history . Following the outbreak of the American Revolutionary War , the Royal Navy sent the , a frigate commanded James Wallace as captain to put a halt to smuggling out of Newport . On June 13 , 1775 , Nicholas Cooke , the colony ' s lieutenant governor , officially asked Wallace to return two ships he had captured . Two days later , the $ 3 authorized the to acquire two ships for the purpose of defending the colony ' s trade , established a committee to oversee the acquisition and fitting of the ships , and appointed Abraham Whipple as commodore of the fleet . Two sloop s were purchased , called " Katy " and " Washington " . Commodore Whipple reported that the same day , June 15 , he captured a tender of the " Rose " . The navy was organized under , and subject to the direction of , the state ' s militia generals . In January 1776 two more ships were authorized , and an admiralty court was established to adjudicate maritime matters , including the distribution of prizes . The legislation also authorized the governor to issue letters of marque , making privateer ing possible . The latter legislation was amended the following May to harmonize it with Continental Navy regulations . About 200 ships engaged in privateering on behalf of the state . The General Assembly authorized two more armed ships in 1777 , but none were apparently acquired . It also authorized the purchase of merchant ships for the state ' s use , which resulted in the acquisition two sloops , " Aurora " and " Diamond " . Further authorizations occurred in 1778 in supported of an anticipated expedition to expel the British from Newport ( which failed in the August Battle of Rhode Island ) , but were only fulfilled later , with the acquisition of the galley " Pigot " and the sloop " Argo " , which were commanded by Continental Army Lieutenant Colonel Silas Talbot . The last ship commissioned by the state of Rhode Island was the " Rover " , a sloop that saw only brief service in 1781 . Naval operations . " Katy " and " Washington " primarily cruised in Narragansett Bay in 1775 . In August , General George Washington , seeking any possible supplies of gunpowder , suggested that the Rhode Island ships be used for an expedition to Nassau where there was believed to be a supply of gunpowder . " Katy " was sent on this errand in September , returning without success , as the powder had been removed . She was then used in November to transport Esek Hopkins and other recruits to Philadelphia for service in the recently - created Continental Navy . On her arrival there , she was commissioned into the Continental Navy as the . The " Washington " fate is uncertain ; she sometimes left the bay to warn arriving ships of British threats , but was not particularly seaworthy , and was probably returned to her original owner . In January 1776 two row galley s , named " Spitfire " and " Washington " , were added to the fleet . Both saw service in the defense of New York City in the fall of 1776 , but returned to Rhode Island waters . The " Spitfire " ran aground at the northern end of Rhode Island in March 1777 and was burned to prevent her capture by the British . The " Washington " was reported to blow up near Bristol in April 1777 . Colonel Talbot , as commander of " Pigot " and " Argo " , captured a number of prizes , and was ultimately rewarded with a Continental Navy commission ; the two ships ended their service in 1780 .
