USS Frank Knox has the same armour layout as the USS Gearing, the lead ship of the Gearing class. This means she has a main belt of 0.75 inches, which is surprisingly well armoured for a destroyer of this rank. This is more than the 0.5 inches of the Porter class and the same as the earlier Fletcher class. This belt cannot stop more than 20 mm autocannons, but it significantly lessens spall damage from HE shells from other destroyers and light cruisers. The dual turret mounts have 0.125 inches of armour on the front, sides, rear, and top, and there is a 0.5-inch deck armour plate covering the machinery spaces.

The magazine is placed under the aft turret, and is protected by fuel tanks on both sides of the hull. These fuel tanks will protect the magazine from high explosive shells, but any SAP or AP will slice straight through and ammorack the ship. Captains of USS Frank Knox should avoid taking hits to the stern of the ship whenever possible, and evasive action is recommended as any direct hit under the aft turret will most likely result in total loss of the ship.

As for crew count, USS Frank Knox is quite well off. With a crew count of 336, Frank Knox is able to lose more crew members and keep fighting in comparison to her older Porter-class and Fletcher-class predecessors, allowing her to stay in the fight for longer. This can allow captains of USS Frank Knox to serve as a flotilla leader and absorb shots in some situations, although as stated before it is not recommended to do so while the stern is within the line of fire.

The primary battery has enough armour to stop some spall damage from misses with high explosive shells, but any direct hit from any destroyer calibre gun or higher will inevitably knock the mount out of action. The secondary battery has no armour whatsoever, and splash from hits or near misses will commonly damage or destroy the battery. It is recommended to avoid repairing these whenever possible, as they will inevitably be destroyed again and drain more crew from the ship.

An important part of the ship's armament responsible for air defence. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship's anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets. If there are no anti-aircraft armaments, remove this section.

Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
