Their vessels had to be fast to be able to chase smugglers and have shallow draft, so they could get into the smaller bays and inlets along the coast.
Today, all vessels in the Coast Guard fleet 65 feet and longer are called cutters. As part of the Naval Act of , the US Congress authorized the building of six ships to establish a permanent navy. These first US Navy ships were heavy frigates, which were not as big as ships-of-line but were strongly built and heavily armed. She is a three-masted full-rigged, wooden ship and serves as a museum ship.
Look for her underway in Boston Harbor this summer during the War of OpSail parade of tall ships. Historically though, sea captains would careen their vessels in shallow water by either heaving it over on its side while it was still afloat or by anchoring in shallow water at high tide and then waiting for the tide to go out.
The vessel would touch bottom, and, as the tide went out, lay over on its side. How does one go about getting a ship, especially a big ship, high and dry out of the water today?
On the other hand, frigates are more common, with almost every navy in the world in possession of a frigate as part of its navy fleet, while only 13 nations possess destroyers, according to the Global Fire Power Index Frigate vs destroyer — what are some of the key differences? Almost every navy has a frigate Of the 55 nations that own frigate ships, China leads the world with 52 frigates across three different classes, followed — perhaps surprisingly — by Taiwan, which has 24, and the US with 22 vessels.
Destroyers are much less common, with only a handful of navies possessing these kind of warships. The US Navy owns the most destroyers with 68 currently in service. Japan comes in second with 37, followed by China, which owns 33 vessels. Some nations, such as Spain and Germany, officially have no destroyers although many of their frigate ships are almost identical to what other nations would class as a destroyer vessel.
Destroyers are usually bigger… Destroyer warships come in a range of sizes. The Zumwalt class weighs in at nearly 16,t making it double the weight of smaller destroyers that weigh in at around 8,t at full load.
They are roughly the same width as destroyer vessels. They can thus provide theatre wide air and missile defence for forces such as a carrier battle group and typically serve this function.

Despite its impressive size, the Zumwalt-class destroyer can travel up to 30kn, slightly slower than the smaller Sovremenny and Daring classes, which have an average of 32kn. The Zumwalt class is still as fast — if not faster — than most frigate classes. Weapons and EW capabilities vary based on roles Unsurprisingly, both frigates and destroyers are armed with the latest weapons and defence systems, which are vital for carrying out their escort and protect roles.
ASW-enhanced frigates come with helipads and hangars that accommodate helicopters capable of identifying and attacking nuclear submarines using torpedoes and depth charges.
