with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.89 "Imperial Navy".
General info
Survivability and armour
Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.
Mobility
Write about the ship's mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward and reverse speed.
Armament
Primary armament
Primary weapon is a relatively low-shell-speed, high-arcing, high rate of fire dual-barrel 40mm Vickers autocannon. It's an excellent weapon for relatively quickly dispatching targets within 1.5km range, where it's high rate of fire can be used to correct lead and land number of shots before the need to reload. It's extremely useful against small fast vessels, such as hydrofoil torpedo boats. At range however the flight time becomes a near-impossible for tracking anything smaller than a sub-chaser. There is, however, one advantage to the gun at >1500m range: due to it's low shell speed gun will fire at a very high arc, allowing K-3 to be one of a very few ships within its tier capable of reaching enemies hidden behind near-vertical obstacles, making it an excellent killer for various opponents trying to hide behind the islands or other terrain obstacles.
Secondary armament
The best Anti-Air armament among Japanese Rank 1 ships, extremely useful in fending-off enemy ships, even armored gun boats, and relatively useful against air targets. The only disadvantage is in the guns layout, where at most 2 guns can be firing at a target, due to the fact that two guns amid-ship are pointing in the opposite directions, without any overlapping field of fire.
For bombers the best angle to approach K-3 (and K-7) is from a high angle, directly from the rear, where none of the weapons have any coverage.
Special armament
Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can take an off-guard opponent by surprise. Evaluate the ammunition of this type of armament and rate its performance in combat. If there are no special armaments, remove this section.
Usage in battles
K-3 will be a difficult vessel to play until unlocking fire protection system, as it's extremely easy to ignite and fires quickly dispatch it from the battlefield - for that reason when attacking Type K-3 it's highly recommended to use HE shells on every occasion. Sub Chaser's primary advantage is in a very narrow hull and an outstanding 40mm gun. The ship is so narrow in fact that it's near-impossible to hit for a motor torpedo boats when facing bow (front) or stern (rear). On the other hand, its length is one of, if not the longest in BR, being a serious issue when faced with torpedoes, therefore care should the taken to pre-emptively position oneself when engaging opponents.
The ship is best taken equipped with less than a half of a total ammunition capacity, as it's more than sufficient for a vast majority of battles, while significantly lowers the cross-section of the unarmored ammunition racks that are prone to explosions. Also ignoring depth charges is recommended due to their extremely limited usefulness while adding mass and risk of explosion to the ship.
It's generally good to have at least some HE-DF ammunition onboard, as with a rapid fire of the 40 mm Vickers it can dispatch a field of flak fire very effectively destroying enemy bombers and fighters, or at least scaring them off. Within Rank 1 battles 40 mm HE clips are a better choice than the Universal or SAP, as none of the targets will have enough armor to resist them even at 2000m, while additional explosive power increases the speed in which enemies can be destroyed.
Both: K-3 and K-7 have a relatively undefended rear arc, where at most only one 20mm anti-aircraft gun can shoot back.
Pros and cons
Pros:
- Effective 40 mm twin cannon
- Secondary armament is very powerful against small ships
- Decent anti-aircraft artillery for its battle rating
- Decent speed
Cons:
- Long ship length makes for an easy torpedo target
- Primary armament is not very effective against big ships
- Prone to catching fire
- Large turning radius
- Big size for its battle rating
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.
