When looking at this fighter, a pilot may complain at the lack of ordnance options available, being only limited to a single 37 mm and two 23 mm cannons with what seems to be only a handful of ammunition rounds between them. Without the addition of suspended ordnance, the flight model will not change due to added weight of bombs, missiles, rockets or gun pods, since none are available and the aircraft wasn't designed to use them.
 
  
−
As such, this fighter was built almost like a rocket, needing to get to bomber altitude as fast as possible and intercept inbound bombers. The limited ammunition prevents the pilot from just ''spraying-and-praying'', but instead requires trigger control to maximize rounds on target. This is especially important in realistic and simulator battles where after the ammunition is expended, the pilot must return to base to reload.
+
'''Armour type:'''
  
−
The MiG-9 has enough speed to get to 5,000 m within about 4 minutes, however once there, it is best to either target bombers and go higher if needed (13,500 m is maximum altitude for the fighter) or to then turn the MiG-9 into a diving fighter and going for quick hits before zooming back up. Immelmanns and Split-S manoeuvres are recommended to change directions as this fighter is a very slow turner, taking about 30 seconds to make a complete circle. It is important to keep the speed up on this fighter due to when it becomes slow, it then becomes an easy target for enemy aircraft.

The MiG-9, unfortunately, is not built like a tank and as a bomber interceptor, it had to be constructed like one, sacrificing armour for speed. The aircraft does feature 55 mm of bulletproof glass on the canopy windscreen and two 12 mm steel plates on both sides of the 37 mm ammunition magazine, but that is it for aircraft protection. All the protection is in the front which is meant to offer defence from any defensive gunners on enemy bombers. From the front profile, the armour plates and glass do a good job of shielding the critical components, however, from just about any other angle, the pilot, engines and fuel tanks are clustered in the centre of the aircraft and are all vulnerable from machine gun, cannon, missile and rocket damage. The MiG-9 (l) does have a little more of a weight issue that the standard [[MiG-9]] in that it has fuel pods at the end of the wing-tips which both add more weight and slightly decrease manoeuvrability.

The '''''{{PAGENAME}}''''' is armed with:
+
Thanks to its performant gun, the {{PAGENAME}} is effective as a tank destroyer at long range with the good penetration of its APCBC round. With a maximum penetration of 64 mm at 1,000 m, the vehicle will have no problem penetrating the angled front armour of many similar rank vehicles from a distance. Light tanks, armoured cars and SPAA are the easiest targets. The vehicle's effectiveness improves once the HEAT shell is unlocked, with 100 mm of penetration at all ranges. This allows for reliable penetration of practically all the Semovente's potential adversaries. Your most dangerous opponents are fast and agile light tanks such as the M22 that can easily flank the Semovente undetected and disable you from close range. Their speed and small size make those light tanks difficult to target for the Semovente's gun.
  
−
* 1 x 37 mm N-37D cannon, nose-mounted (40 rpg)
+
With the HEAT shell, the Semovente can make for an effective tank destroyer, provided you stay at a distance guaranteeing your survivability. The one thing to remember about the HEAT shell is that it sacrifices the one-shot capability of APCBC, meaning that larger tanks will often take multiple hits to disable while the reload time is pretty slow for the battle rating. Like the 75/32 M41, the HEAT shell has a good muzzle velocity making it capable to hit reliably targets at long range.
−
* 2 x 23 mm NS-23K cannons, chin-mounted (80 rpg = 160 total)
 
  
−
To fulfil the role of a bomber hunter, the best weapons for mid to late 1940s aircraft was rockets and cannons. Bombers were typically large aircraft and machine guns would not do the job. Bomber interceptors needed to get to the target and spend the least amount of time on target not only for their own safety but to be able to intercept multiple targets before needing to return to base to refuel or rearm. The N-37D and NS-23 cannons centrally mounted on the MiG-9 virtually nullify the need for messing with convergence, allowing the pilot to sling both ammunition types at bombers at 690 m/s. In a high speed pass only so many rounds could be fired off before the MiG was zooming past and needed to set up for another run if they missed.
+
;Notable enemies:
  
−
Having the 37 mm and 23 mm cannons helped ensure if the critical areas are hit, only one pass is needed. Without rockets or missiles to provide backup or alternative weapon options, proficiency with the cannons is a must. The "Air targets" ammunition belt provides provide a large amount of HE ammunition, which will critically damage enemy targets, even without a precise hit.
+
Many tanks are capable of easily disabling you. By order of lethality:

The MiG-9 (l) requires altitude to be most effective in either of its two main roles. While flying full throttle into the middle of the map may seem like the noblest thing to do, it may end your piloting career faster than you care for, not allowing you to reach your full potential during the match. Best bet for this fighter is to start side climbing on the map or working on gaining altitude away from where the main group of aircraft are flying as this provides you with a relatively safe area to climb and allows you to see any enemy aircraft which may be gunning for you and give you enough time to respond or dive away. It is important to begin your side climb flying straight until the fighter reaches speeds of about 500-550 km/h when the climb angle can be increased to about 15°.
+
;How to defeat a {{PAGENAME}}
  
−
When you reach an altitude of where the bombers are at, you can then begin to patrol and set up for any attack runs. Typically it is best to have some altitude over the bombers as this will allow you to gain more speed when driving and make it that much more difficult for the defensive gunners to hit you. Flying towards the rear of the bomber is the worst angle to come at, while it makes it easy for you to line up the target, you will actually be flying into bullets fired at you causing them a chance for deeper penetration into your jet than if you came from another angle. Due to the limited amount of ammunition, controlled bursts are best especially when aimed at engines, cockpits or fuel tanks. Carefully aim at these critical components and let the ammunition do the rest for you. It is best not to linger around a target, instead, add full power and zoom away until you are at least a kilometre or two away and outside of the range of any defensive turrets before manoeuvring for another run.
+
The {{PAGENAME}} has several weak spots:
  
−
If there are no bombers to attack, either because they have all been destroyed or waiting for more to spawn (in Arcade battles, some pilots tend to leave their attackers/bombers as late match reserves), then when at altitude, you can patrol and look for unsuspecting fighters or you can work to lure aircraft up into a stall fight. From your perch, you can start to dip down towards a fighter as if you are going to pounce on it, if they take the bait and climb to meet your MiG-9 (l), then pull up as if you ''chickened-out'' and are running, begin a moderate climb with your speed and watch as they follow up, especially watch for the condensation trails coming from their wings, this is a good indication that they are beginning to stall and are an easy target. The MiG-9 (l) has a rather larger rudder and can make use of it for a wing-over manoeuvre which will put you in line with the stalled out target allowing for you to get a quick shot off before returning to your patrol altitude. It is recommended to take 20 minutes of fuel; even though it greatly reduces performance at the start of the match, it allows for you to freely use 108% as well as having a much longer-lasting presence over the battle.
+
* In a frontal encounter, the vertical front plate is the easiest to target.
 +
* Shoot the lower front plate to damage the transmission and immobilize the tank if you lack penetration power.
 +
* When flanking, aim for the weak sides of the casemate.

====== The very first jet on Chinese soil ======
+
Following the success of the Semovente da 75/18 in its anti-tank role, the Italian command ordered in October 1942 the development of an improved version of the Semovente based this time on the M15/42 chassis and a 75 mm L/34 Breda cannon, a gun with identical performance to the one equipped on the P26/40 tank. The new vehicle was accepted in April 1943 and production started in May 1943 with an order for 280 Semoventi. Due to wartime shortages of materials and manpower, only 93 tank destroyers were produced by the Italians before the Armistice and only 60 vehicles delivered to their combat units. The Germans then seized control of Northern Italy and continued its manufacture, completing 80 more units alongside 36 already confiscated ones.
−
After the outbreak of the Korean War, the very first major battle between the East and the West as well as jets, Mainland China was also involved in this 3-year war against the UN forces; one major problem for the newly-born PLAAF was that they have none jet aircrafts from any country. Also during the mid-1950, the Nationalist forces and USAF would often perform air raids to major cities like Shanghai, Guangzhou and the new capital of Beijing. Thus between August 1950 to January 1951, VVS transferred 13 fighter divisions, with 9 of them equipped with MiG-9s to defend these cities. This was the very first time Mainland China got their hands on jets and later they decided to purchase some MiG-9s from the Soviets as well, both PLAAF and VVS expected MiG-9 should be sufficient enough to handle new USAF jets.

Later from April till June 1951, PLAAF received 358 out of the total of 369 MiG-9s in their service, where the VVS transferred them straight to PLAAF at Mainland's airfields, while there were some [[MiG-15 (Family)|MiG-15]]<nowiki/>s that came into service in PLAAF, most of the new divisions of PLAAF had only MiG-9s on their hands; while they might be handy and sufficient to shot down propellers, 4th division of PLAAF reported back that at the Korean theatre, MiG-9s were totally inferior than the late [[F-84 (Family)|F-84]]<nowiki/>s used by the USAF; let alone the later [[F-86 Sabre (Family)|F-86 Sabre]]. Thus in mid-1951, the Soviet Union decided to replace all the MiG-9s in service of 6 fighter divisions with MiG-15s for free. That is, the payment for the MiG-9s that was ordered in May 1951 would be upgraded to MiG-15s with no extra fees other than transportation cost of MiG-15s from Soviet mainland, making MiG-9s a "gift" of these MiG-15s. Although MiG-9s had very little contributions to the war due to its performance, but PLAAF saw it as a trainer to train propeller pilots into jet pilots, as the intermediate between La-9/11s and other captured fighters into the latest MiG-15 bis, with the rapid replacement with MiG-15s during July till October 1951, these jets were now mostly used as aforementioned, a jet trainer for new units before MiG-15s were delivered.

Description

The Semovente 75/34 M42 is a rank Italian tank destroyer with a battle rating of (AB), (RB), and (SB). It was introduced in Update 1.85 "Supersonic".

General info

Survivability and armour

Armour type:

  • Rolled homogeneous armour (hull, casemate)
  • Cast homogeneous armour (gun mantlet)
Armour Front (Slope angle) Sides Rear Roof
Hull 25 mm (80°) Front glacis
30 mm (cylindrical) Lower plate 		25 mm 25 mm Upper part
25 mm (15°) Lower part 		25 mm (10°) Front glacis
10 mm (15°) Rear - Engine hood
5-10 mm (8°) Rear - Radiator vents
Casemate 50 mm (5°) Casemate front plate
50 + 50 mm (spherical) Gun mantlet
25 mm (60°) Plate connecting with hull 		25 mm (6-7°) 25 mm 15 mm (5°) Centre
15 mm (21-22°) Sides

Notes:

  • Suspension wheels are 15 mm thick while tracks are 20 mm thick and bogies 10 mm thick.
  • The belly is 15 mm thick.
  • Mudguards are 4 mm thick.

The 75/34 M42 shares the same vulnerabilities as the 75/18 M41 and the 75/32 M41: a rather weak vertical armour front plate, weak sides and an even weaker roof armour and a crew of only 3 sitting in a cramped space.

Usage in battles

Combat tactics

Thanks to its performant gun, the 75/34 M42 is effective as a tank destroyer at long range with the good penetration of its APCBC round. With a maximum penetration of 64 mm at 1,000 m, the vehicle will have no problem penetrating the angled front armour of many similar rank vehicles from a distance. Light tanks, armoured cars and SPAA are the easiest targets. The vehicle's effectiveness improves once the HEAT shell is unlocked, with 100 mm of penetration at all ranges. This allows for reliable penetration of practically all the Semovente's potential adversaries. Your most dangerous opponents are fast and agile light tanks such as the M22 that can easily flank the Semovente undetected and disable you from close range. Their speed and small size make those light tanks difficult to target for the Semovente's gun.

With the HEAT shell, the Semovente can make for an effective tank destroyer, provided you stay at a distance guaranteeing your survivability. The one thing to remember about the HEAT shell is that it sacrifices the one-shot capability of APCBC, meaning that larger tanks will often take multiple hits to disable while the reload time is pretty slow for the battle rating. Like the 75/32 M41, the HEAT shell has a good muzzle velocity making it capable to hit reliably targets at long range.

Notable enemies

Many tanks are capable of easily disabling you. By order of lethality:

  • Tank destroyers with long guns
  • Howitzers with powerful HE shells
  • Tanks with HEAT shells
  • Frontline tanks with APHE shells
  • Light tanks or armoured cars with autocannons
How to defeat a 75/34 M42

The 75/34 M42 has several weak spots:

  • In a frontal encounter, the vertical front plate is the easiest to target.
  • Shoot the lower front plate to damage the transmission and immobilize the tank if you lack penetration power.
  • When flanking, aim for the weak sides of the casemate.

Pros and cons

Pros:

  • Decent 75 mm gun with a respectable reload rate
  • Low profile = harder to spot
  • Has access to HEAT rounds
  • Decent top speed
  • Large explosive filler in the APCBC round almost guarantees vehicle destruction upon penetration

Cons:

  • Overall armour is not very good
  • Is vulnerable to getting flanked due to being a casemate tank destroyer
  • Thin top armour; can be vulnerable to strafing aircraft
  • Acceleration leaves things to be desired
  • Shells have a rather slow muzzle velocity

History

Main article: History of the M15/42
Development

Following the success of the Semovente da 75/18 in its anti-tank role, the Italian command ordered in October 1942 the development of an improved version of the Semovente based this time on the M15/42 chassis and a 75 mm L/34 Breda cannon, a gun with identical performance to the one equipped on the P26/40 tank. The new vehicle was accepted in April 1943 and production started in May 1943 with an order for 280 Semoventi. Due to wartime shortages of materials and manpower, only 93 tank destroyers were produced by the Italians before the Armistice and only 60 vehicles delivered to their combat units. The Germans then seized control of Northern Italy and continued its manufacture, completing 80 more units alongside 36 already confiscated ones.

Combat usage

The 75/34 M42 saw shortly combat action on the Italian side during the battle of Rome in September 1943 and more extensively on the German side along with the other Semovente variants in Northern Italy and the Balkans in 1944.
