Description

GarageImage MO-4.jpg


The MO-4 Type is a rank I Soviet motor gun boat with a battle rating of 1.7 (AB/RB/SB). It was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game.

General info

Survivability and armour

The MO-4 is not armoured at all, and can be easily destroyed by even a rank 1 ship at close range. The MO-4's motor also has a tendency to be set aflame quite easily by damage. The silver lining of the MO-4's survivability is that the ammunition are stored in the boat under the sea level, and so they are somewhat harder to hit and detonate, instantly destroying the ship.

Mobility

Without upgrade, the ship is slow, reaching only 40 km/h and is pretty sluggish. However, when fully upgraded, the MO-4 handles very well and can reach 75 km/h.

Armament

Primary armament

This ship has access to two manual 45 mm cannon that can use AP ammo (against armoured boats) and three types of HE ammo. The default one and one of the unlockable ones (OR-73A and F-73 respectively) can be used to hit distant target due to their greater muzzle velocity. The O-240 HE shell has greater explosive filler, but lower muzzle velocity, and so is more effective at closer ranged targets.

However, these guns leave the crew exposed due to the lack of armour, so even enemy machine guns can incapacitate these guns. As such, try to stay at range to prevent this from happening.

Secondary armament

Main article: DShK (12.7 mm)

The anti-air armaments of the MO-4 consist of a total of two 12.7 mm DShK machine guns. These guns should be primarily against the aircraft, which are relatively easy to take down at BR 2.0, but they can also be used against the lightly-armoured boats that are still present at this battle rating (such as the LS 3). The guns are positioned in the middle section of the ship, which should pose no problems against aircraft because at least one gun can be placed onto the enemy aircraft, but it can be hard to attack boats directly in front of the ship.

Special armament

Main articles: BB-1 depth charge, M-8

One big firepower improvement on the MO-4 is the ability to equip the M-8 rockets. With a total of 64 rockets (32 on the deck ready to use), this ship can destroy almost anything, armoured or not, at very close range. While this ship should not be used at close range due to the lack of protection, rockets can be used in a last ditch effort to defeat rushing enemies or if in need of a quick-reacting weapon to surprise-attack someone. Do not underestimate the psychological effect of the rockets on newer player that may try to run away seeing/hearing them.

Usage in battles

The MO-4 has dangerous long-range firepower at a very low battle rating, but limited defense against fast and evasive enemies and air power. Accordingly, the MO-4 should fight conservatively at the longest possible range the crew's gunnery skill could reach. At this battle rating, very few opponents will have large-caliber guns that can compete at range, and even fewer players will be able to target them effectively, so use that to the ship's advantage.

Since the MO-4 does not have good anti-air defense, with only two 12.7 mm for the job, it should be used as a first spawn ship or at least stay close to allies with good anti-air defenses to extend its lifespan.

Do not forget to use the M-8 rockets when in a bind, they could pull the MO-4 through desperate situations.

Pros and cons

Pros:

  • Two large 45 mm cannons on bow and stern of the ship
  • Two secondary machine gun turrets
  • Many rocket pods, placed on the bow of the ship able to do a lot of damage to almost anything at close range

Cons:

  • Primary cannons have a low rate of fire
  • Turrets have low turning speed
  • Crew are incapacitated very easily due to lack of armour
  • Good speed requires the purchase of all seakeeping modules
  • Wooden hull can catch on fire more easily

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).
