The main detriment relative to the speed though is in regards to its survivability, as this vessel is relatively unarmoured, large and slow for its battle rating, it accumulates a lot more damage due to the slow speed, this unfortunately makes it a very easy vessel to hit and critically damage. | ||

Due to its lower muzzle velocity, it can be difficult to aim, but a few shells will knock out any small ships you face.

These cannons perform very well against aircraft and boats alike, however they can't fire directly forwards, as the cabin blocks the line of sight. All in all, its a modestly powerful weapon and more reliable than the primary 57 mm gun. The magazine for each cannon contains 20 rounds and reloads very quickly, allowing for a steady stream of fire against enemy vessels or aircraft. It comes with three belts: | |

This is especially important as the Ha-Go is very vulnerable to close range machine gun fire and autocannon fire in general due to its exposed crew compartment, and will quickly lose out in longer engagements.

Description
The Ha-Go (mod. 1) is a rank II Japanese motor gun boat with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.89 "Imperial Navy".
General info
Survivability and armour
The hull of the Ha-Go is made up of 6 mm steel, with no additional armour protection. In addition, it only has a crew of 10, which overall does make it a fairly weak vessel. It is quite low down in the water, which may cause enemy boats to miss the hull at the longer ranges but this really is the only passive advantage the Ha-Go has in terms of survivability. At the closer ranges though the vast majority of enemy vessels will be able to tear through the hull of the Ha-Go fairly easily, it's also very vulnerable to high calibre cannons as well, and can be hull broken if it takes a shot from one of these cannons.
Mobility
The speed and mobility of this vessel is notably one of its weakest assets, it can reach 34 km/h in AB and 25 km/h in RB. It's fairly unresponsive to changes in speed but not necessarily changes in direction, it takes a long time to accelerate and decelerate but it can turn and change direction fairly easily, which is useful for maintaining angles of attack for the weaponry. The main detriment relative to the speed though is in regards to its survivability, as this vessel is relatively unarmoured, large and slow for its battle rating, it accumulates a lot more damage due to the slow speed, this unfortunately makes it a very easy vessel to hit and critically damage.

History
Ha-Go Fighting Boat Model 1 (波號戦斗艇一型), also known Se-Ha (せは艇) was one of the first prototypes of small escort boats (小護衛艇) by the Imperial Japanese Army. It was designed to escort "Daihatsu"-class landing crafts that were transporting munitions to offshore islands.
In January 1944, the Imperial Japanese Army 10th Technical Research Institute ordered Hitachi Zosen Sakurajima shipyard to make two types of small escort craft. The first, called Ha-Go Fighting Boat Model 1 "Se-Ha" (Ha-Go meaning "Mark A"), was to be equipped with two 150 hp engines, and a second named the Ha-Go Fighting Boat Model 2 "Se-Ni" equipped with two 60 hp engines.
The Se-Ni was completed in October 1944 but the top speed was only 9 knots so the plan was cancelled. Se-Ha was eventually completed in December 1944, but after trials the engineers decided to try to modify the design to get more speed.
A third design, "Se-Ha Kai" was completed in July 1945. In a trial cruise during October 2-5, its speed reached 13 knots so research ended. By the surrender of Japan, it had not been formally adopted, but would have been officially named the Type 5 Small Escort Boat. ("Type 5" already in game is Large Escort Boat.)
