Description
140 mm/50 3rd Year Type (140 mm) is a main gun type on an early Japanese Light Cruisers. It's a relatively competent weapon, offering good performance against enemy ships, however being unable to effectively engage hostile airplanes.
Vehicles equipped with this weapon
General info
The cannon has the lowest calibre among its peers, what gives a significant disadvantage in a gunfire. It's not until unlocking the Type 1 SAP shells that the ship is in an absolute disadvantage against other light cruisers using equivalent shells.
Available ammunition
Standard HE shell is a relatively good all-rounder, that should be taken to every match, it's useful primarily against Destroyers and Motor Torpedo Boats. Type 2 SAP (Tier I modification) shells are comparatively weak, with little direct damage and mediocre fragmentation damage, despite having larger explosive filler than its successor. Their usefulness is limited to taking down engines and transmissions. They are wholly superseded by Type 1 SAP (Tier III modification) that has both: higher damage upon piercing the component and higher fragmentation damage. Finally, the HE-DF shells (under the same designation as the regular HE shells - type 0 HE) are dedicated anti-air shells, however, due to poor vertical guidance (+20° or +30°, depending on the mount, compared to +75° on Type 3 guns) their effectiveness is severely limited. Note that HE-DF shells are inefficient even against wooden boats, as they will explode at a significant distance in front of the target, doing negligible damage to anything that is not moving >100 km/h towards the shell.

Comparison with analogues
Comparing to the primary weapons on the ships of the same BR 140 mm/50 3rd Year Type (140 mm) is grossly outmatched in terms of caliber, which results in low muzzle velocity, TNT equivalents, and penetration capabilities. Lacking firepower is not helped by the number of barrels available on the ships bearing the gun, offering at most 6 shells fired at the same time, which is about average for the BR. The only saving grace is its damage potential per minute with the Type 1 SAP shells, especially when firing from the first-stage stowage, where its damage potential can be theoretically higher than the one of its peers.
Concluding, the 3rd Year Type can be considered the weakest cannon among its peers.

Usage in battles
140 mm/50 3rd Year Type (140 mm) should be used in gunnery fights, preferably at ranges of ≈8 km, in an attempt to outshoot the opponents thanks to a higher rate of fire than the peers. Due to slow shell speed shooting at targets beyond 11 km is mostly in vain, though given a large supply of ammunition there is not much harm in trying to score lucky hits.
Pros and cons
Pros:
- Good fire rate
- Decent damage output per minute for the Type 1 SAP shells among peers
Cons:
- Low damage output among all shell types when compared with the equivalents
- Very low shell speed across the board
- HE shell has the lowest explosive mass TNT equivalent among peers
- Even the best AP shell has the lowest penetration among peers
- Type 2 SAP shell is largely useless
History
140 mm/50 3rd Year Type (140 mm) (50口径三年式14cm砲) was introduced in 1916 and became the world's most common coastal defense gun during WW2, as well as being used on a number of pre-war capital ships.
It was conceived as a successor to the 15 cm/50 41st Year Type (50口径四十一式15cm砲). Design arose from the need for a quick-firing gun that could sustain a fire rate for longer periods of time. This lead to a decrease in caliber and as a result - 16% lower mass of the shells. The first capital ship to bear the gun was the battleship Ise, completed in 1917. Gun was originally planned to be used on a number of light cruisers and capital ships, however, due to Washington Naval Treaty (1922), a number of constructions had to be canceled or modified, with the guns relegated to the coastal defense. Guns were manufactured in two gun factories - at Kure with mounts (neighbor city to the Hiroshima) and Muroran (on Hokkaido island), presumably only for coastal defense.[1][2]
Throughout the operational history of the gun a number of shells were used that are not illustrated in the game, including anti-submarine projectiles introduced in 1943 and the Type 3 Anti-Aircraft shells, better known as Sankaidan (三式彈), and the illumination rounds[1][3]
Single-gun mounts that we can find in the game had a mass of 21 tonnes, 5.7 of which was the gun with the breech. The operation of the mount was fully manual, with both, horizontal and vertical targetting speed of 8°/s. Guns could be elevated down to -7° and up either 25° or 30°, depending on a specific mount. The maximum range of the weapon was 19 km at 30°.
