Description
The PC-461-class, Carmi (PC-466) is a premium rank II American sub-chaser with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision".
The Carmi is more specialized in long range fire support compared to the other early American sub-chasers, owing to her armaments of two 3-inch (76 mm) guns. As she is frequently matched against fast and manoeuvrable PT boats, these weapons can be quite hard to handle at first. However, as the guns pack considerable punch for their BR, along with her durable steel hull, she is capable of going toe-to-toe even against a much superior foe at higher BR when handled correctly.
General info
Survivability and armour
The Carmi is comparably similar to the PC-451. Her steel hull, armour, and large size provides good protection against machine guns and can resist 20 mm autocannons when angled properly. The Carmi is longer than the PC-451, which gives her more crew space to accommodate 65 sailors (19 men more than the PC-451) while also being a larger target. When used properly, the Carmi is able to hold on her own against coastal boats at higher ranks.
Mobility
As a larger sub-chaser, the Carmi's mobility isn't something to write home about. She is, however, quite manoeuvrable for her size. Allowing her captain to evade close range torpedoes if spotted early enough.

Armament
Primary armament
The PC-466 Carmi has access to two 76 mm Mk 10 guns as its main armament. The Mk 10 gun is a great main gun for low tier naval battles, being capable of crippling or outright destroying many coastal ships with a single hit. However, this gun is an early version and lacks the full automatic fire of later American 76 mm cannons. The gun gets access to three shells - HE, AP and HE-VT. Of these shells, the HE shell is almost always the best choice, packing the largest punch against enemy boats. Despite this, it is wise to bring a bit of the other shells, for use against aircraft and armoured vessels.

Secondary armament
The PC-466 Carmi has access to two single 20 mm Oerlikon cannons for anti-aircraft defence. The 20 mm Oerlikon cannon was the standard light anti-aircraft gun for several nations, including the United States, and replaced the prior AN/M2 Browning machine gun. This weapon is an effective short-range AA gun, and has great firing angles. The weapon has access to three belts - Default, AP and HE. Of these, the HE belt is by far the most effective against boats and aircraft due to its high explosive mass. As well, the guns fire from a drum magazine that will need to be reloaded. Because of the magazine design, the gun will not jam with continuous fire.

Additional armament
This ship can be armed with depth charges, once they are researched. These come pre-armed with a 3-second fuse, and once dropped in the water will explode after this time. You can adjust the fuse time in the menu in the Battle Lobby when you select the ship. Depth charges can come in quite handy if you have a boat or ship close on your aft, and you can't turn around to shoot them. This type of situation comes up mainly at Capture Points when there are multiple enemy ships or boats trying to capture the point and destroy you. Just get pointed straight and drop 2-3 of them behind you. (Left-Ctrl by default). Even if the boat or ship is fast, the charge will either break their hull or cause significant damage to the vessel, allowing you to get away or turn around.
Usage in battles
The Carmi performs best at longer range (~2 km) where she can outrange most of the PT boats and is less vulnerable to flanking. Her 76 mm guns can be a bit tricky to use at first, especially against fast PT boats. But it does have great damage output. Situational awareness is a key of success of playing this boat, as knowing when to switch between the 76 mm and 20 mm guns can be rewarding.
Pros and cons
Pros:
- Two 76 mm guns pack a heavy punch for its rank
- Good survivability for its BR
- Decent traverse speed
- High crew count of 65
Cons:
- Mediocre top speed
- Very large target
- 76 mm guns is somewhat harder to use against fast PT boats
- Secondary 20 mm Oerlikon guns has limited coverage
History
The PC-461-class submarine chasers were a class of 343 ships built for the United States Navy. Their design was primarily based on the experimental PC-451 and PC-452 submarine chasers. The class saw extensive use in most theatres of World War II, either under the US flag or other Allied countries under the Lend-Lease program. While the class was not particularly successful in its intended role, being confirmed to have sunk only one submarine throughout the war, they found more success as a gunboat, as such were frequently deployed to support landing operations, including Normandy. After the war, the ships were later used by 22 countries around the world, primarily as coastal and riverine patrol vessels.
Carmi was laid down on September 1, 1941 by George Lawley and Sons in Neponset, Massachusetts. It was launched on April 29, 1942, and was originally named the USS PC-466. It was originally classified as a submarine chaser, but was re-designated as a control submarine chaser on August 20, 1945, and was named the USS PCC-466. During the Japanese surrender, the USS PCC-466 was present in Tokyo Bay, in September 1945. It was decommissioned on March 1, 1947 and was sent to the Pacific Reserve Fleet, Columbia River Group, in Astoria, Oregon. It was once more classified as a submarine chaser, PC-466, on October 27, 1955. It was named the Carmi on February 1, 1956, and was sold for scrap in 1960.
