como disse o Eins , na verdade não existe uma "norma"

Normalmente dá-se a designação Destroyer a um navio com vocação AAW e Fragata a navio com vocação ASW

No entanto as Fragatas F-100 são AAW e são ...fragatas...

Embora sejam equivalentes a Destroyers...

Corveta - Fragata - Destroyer - Cruzador - Kirov

At the beginning of the 21st century, destroyers are the heaviest surface combatant ships in general use, with only four nations (the United States, Russia, France and Peru) operating cruisers and none operating battleships.[1] Modern destroyers are equivalent in tonnage but drastically superior in firepower to cruisers of the World War II era, capable of carrying nuclear missiles able to destroy cities.

In modern navies, frigates are used to protect other warships and merchant-marine ships, especially as anti-submarine warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups, and merchant convoys. But ship classes dubbed "frigates" have also more closely resembled corvettes, destroyers, cruisers and even battleships.

Frigates

In modern military terminology, a frigate is a warship intended to protect other warships and merchant ships as anti-submarine warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups, and merchant convoys. Frigates fulfill a Protection of Shipping (POS) mission as Anti-Submarine Warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups and merchant convoys.

The U.S. Navy adopted the classification "frigate" (FF) for ships used for open-ocean escort and patrol. When they were developed during World War II, frigates were classified as destroyer escorts (DEs). Frigates resemble destroyers in appearance, but they are slower, have only a single screw, and carry less armament. FFs have grown in size from about 1,500 tons displacement to over 4,000 tons, as in the Knox class (FF-1052). Their armament varies from class to class.

The guided missile frigates (FFGs) bring an anti-air warfare (AAW) capability to the frigate mission, but they have some limitations. Designed as cost effective surface combatants, they lack the multi-mission capability necessary for modern surface combatants faced with multiple, high technology threats. They also offer limited capacity for growth.

Destroyers

Destroyers (DDs) and guided-missile destroyers (DDGs) are multi-purpose ships that are useful in almost any kind of naval operation. They are fast ships with a variety of armament, but little or no armor. For protection, they depend on their speed and mobility. Their displacement varies from about 4,500 tons to 7,800 tons. The principal mission of destroyers is to operate offensively and defensively against submarines and surface ships and to take defensive action against air attacks. They also provide gunfire support for amphibious assaults and perform patrol, search, and rescue missions.

so a destroyer is a bigger faster better armed ship and a frigate is smaller lesser armed and slower...right?

Yes, but only to a limited extent.
The frigate has a more strictly defined mission--convoy and fleet protection. While it can perform independent missions, it is not intended for that purpose.
The modern destroyer can function as an independent main combatant, although, admittedly, such missions are few in number (e.g., the Red Sea patrol decades ago, in which a single destroyer remained in the area for a few months, with the responsibility of extracting U.S. nationals from littoral countries that were experiencing unrest).
I suspect that, given increasing ship construction costs and rapidly evolving weapons systems (which usually need a large displacement vessel for installation), it may no longer be cost effective to construct frigate-type 'destroyer-on-the cheap' ships. However, there is now a lot of thought going into another specialized by of warship, that dedicated to 'littoral' combat--sort of a combination of blue-water and brown-water capability. These ships' missions--assuming such a class is constructed--would be oriented toward support of ashore assets and containment of enemy activity near coastal areas.
