Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

VII

annoSU14_1.png

1370000

The SU-14-1 is a Soviet tier 7 self-propelled gun.

Developed on the basis of the SU-14. In 1936 a prototype was manufactured and tested. In 1937 the project supervisor was purged and the project was canceled. The prototype was shipped to Kubinka for storage. In 1941, during the Battle of Moscow, the SU-14-1 was used for long-range bombardment.

The SU-14-1 is considered more dangerous than the S-51 because some players in the S-51 (which unlocks from the KV-2) may not have played any of the earlier artillery, and thus are inexperienced.

The SU-14-1 leads to the SU-14-2.

Player Opinion

Pros and Cons

Pros:


  • Gun range: stock: 1350 m, second: 1400 m, top: 1250 m
  • Very high damage with 203mm mortar.
  • Better power to weight ratio than the S-51.
  • Great ammunition capacity - will never run out.


Cons:


  • Horrifying aim time, but no worse than the two previous Soviet SPGs.
  • inferior to the S-51 in mobility, traverse, and profile.
  • Has SU-8's top gun as stock.
  • No Gun Traverse.
  • Has literally no gun depression, with the gun mounted high above ground.


Performance

The 203mm B-4 gun is more accurate when mounted on this artillery than on the contemporary Soviet artillery, the S-51. Furthermore, you have a significant advantage in ammo capacity.


Early Research

  • Only the 12RT Radio carries over from the SU-8. Mount this immediately.
  • First, research the SU-14-1 Suspension. You have an option to research the 152 mm BR-2 and 203 mm B-4 first although you will not be able to use any equipment over 83 kgs while the 152mm BR-2 is mounted due to weight constraints.
  • If the suspension has been researched first, research the 152 mm BR-2 followed by the M-17F engine as this will give you a bit more mobility for reasonably little XP.
  • Finally, research the 203 mm B-4.

Historical Info

An old Soviet self-propelled artillery piece (SU-14) before its test firing. It was based on the heavy T-35 tank -- note the lack of an armoured box around the gun/crew

The experimental SU-14 was built in 1934 (possibly 2 were built) as heavy self-propelled guns for mechanized units for the destruction of strengthened fortifications.

Specifications: weight- 48,5 t; crew- 7 men; armament- 203mm howitzer B-4 mod. 1931 (range of fire 18 km with 100 kg shell, rate of fire 1 shot/5.7 min) + 3 x 7,62mm MG;- ammunition 8 shells + 2268 MG shells; armour 10-20 mm; engine M-17 500 hp; speed- 27.3 km/h; range 100-120 km.

The SU-14 was based on the T-35 chassis with other elements from both the T-28 and T-35. The engine was located in the front and the howitzer was openly-mounted. The original SU-14 had the 203mm B-4. The SU-14 was equipped with two 200 kg cranes for use with the ammunition, two spades, and had to have its suspension disconnected during firing; it could fire only from the stationary position. Its manoeuvrability and speed were satisfactory. Also, operation of the howitzer was convenient. But, its size was large, armour was insufficient, and it had problems with over-driven transmissions.

The SU-14 was tested in 1935 and its engine and transmission were modified (improved SU-14-1 was built in 1936 - it had better and more reliable transmission, improved spades, more powerful engine M-17F 680 hp). On both Self-propelled Guns, the 203mm howitzer was replaced by the 152.4mm naval gun B-30 and Br-2 (which had better range and rate of fire) in 1936. It was planned to produce 5 copies with the 152.4mm gun Br-2 (SU-14-2), but that plan was rejected due to the arrest of the chief engineers of the project.

See left most (or top most) blueprint below.

Original SU-14 design with the 203mm Howitzer SU-14-1 with the longer ranged 152mm Howitzer

In 1936, the new experimental self propelled gun SU-14-1 was built and tested. It was the improved version of the SU-14 with the transmission from a T-35 heavy tank (not from T-28 medium tank as in the case of SU-14), more powerful engine, modernized spades, and without the ineffective suspension needing to be disconnected during firing. An additional artillery tractor, “Comintern”, was used as ammunition carrier (50-60 shells) for the SU-14-1. See right most (or bottom most) blueprint above.

SU-14 original SU-14-1 with a 203mm

In 1936, the 203mm howitzer was also replaced by the 152.4mm gun Br-2 mod.1935 with better range and rate of fire. The SU-14-1 was equipped with a radio station and additional armour in 1940 for use during the Winter War against Finnish fortifications (Mannerheim line) from a short distance. That SPG was renamed the SU-14-Br2 and was the predecessor of heavy SPGs of the WWII period. Now, the SU-14-2 is preserved at the Russian tank museum (Kubinka).

Combat Usage

The Winter War

The SU-14 was used quite successful in the destruction of Finnish fortifications during the Winter War.

World War II

In April 1940, the SU-14 and SU-14-1 were going through tests in NIAP, and in July, were in P.F. Lebedev's tank group in the Kiev Region. In September 1940, both units were given to NIBT for storage. In the fall of 1941, when defending Moscow, both SU-14s and an experienced SU T-100-U in a unit called "Separate Heavy Division for Special Purposes" were used in the Kubinka Region to fire from protected positions at advancing German forces (likely, they were using any working weapon available).

Variants

  • SU-14 -- Armed with 203mm howitzer B-4 mod. 1931 + 3 x 7,62mm Machine guns; ammunition 8 shells + 2268 MG shells; armour 10-20 mm; engine M-17 500 hp; speed 27,3 km/h; range 100-120 km
  • SU-14-1 -- Armed with 203mm howitzer B-4 mod. 1931 + 4 x 7,62mm MGs; ammunition 8 shells + 2196 MG shells; armour 6-20 mm; engine M-17F 700 (850?) hp; speed 30-35 km/h; range 120-150 km.
  • SU-14-Br2 -- Armed with 152.4mm gun + 4 x 7,62mm MG; ammunition 16 shells + 2655 MG shells; armour 20-50 mm; speed 15 km/h; range 100 km.
  • SU-14-2 -- SU-14-1 with the radio station.

AUTHOR'S NOTE

The variant descriptions and the pictures don't exactly match (they came from 2 different sources). It is relatively clear that only 3 vehicles were produced. 2 were likely the SU-14 with the 203mm and 1 was the SU-14-1 with the 203mm. Later, the 203mm gun was replaced with the 152.4mm gun. However, from the 3 pictures directly above, we get some discrepancies. One picture (1st in the row of 3 above) shows the front view of an SU-14 with both armour AND the short 203mm gun. This does not have a variant name. Likewise, the 3rd picture in the group of 3 shows the original plating between the tracks (you can see where it extends to cover the drive wheels and has rectangular holes instead of circular ones). From the the blueprints, this is an SU-14 and not the SU-14-1 modified to an SU-14-Br2. I'm assuming that the armour was tacked on to one (or more likely both) of the original SU-14 prototypes, but they left the 203mm howitzer in. Possibly, this was done so they could participate in the Winter War.
