== Usage in battles ==

''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

=== Pros and cons ===

''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".''

== History ==

The Churchill NA75 was the Churchill IV upgraded, under 'Operation Whitehot', during the period between March and June 1944.<ref>https://web.archive.org/web/20110222053014/http://northirishhorse.net/articles/na75/1.html</ref>

190 - 200 of these were produced and mainly used in Africa and Italy<ref>https://en.wikipedia.org/wiki/Churchill_tank</ref>

=== Development ===
It was the idea of P.H Morrell who was a captain in command of a detachment of 665 Tank Troops and following the Fall of Tunis Morrell was attached to 16 Base Workshop R.E.M.E and employed in scrapping large numbers of battle casualty armored vehicles accrued during the North African campaign. He stated: "''It was under-gunned - its 6-pdr, with an AP range of 800 yards and NIL HE performance, had proved to be no match for the 75 and 88mm guns of the hull down or dug in German tanks encountered during its advance up the Medjerda Valley"''<ref name=":0">http://www.armourinfocus.co.uk/a22new/articles/na75text.htm</ref>

Morrell noted that often the least damaged part of the scrapped tanks was the main armament, which in many cases, showed a useful remaining life of up to 85%. In light of his views on the effectiveness of the 6-pdr and the internal mantlet of the Churchill, Morrell considered the possibilities of adapting Churchill to take the Sherman 75mm gun.<ref name=":0" />

=== Modifications ===
The first step was to remove the 6pdr together with its mantlet and auxiliary gear from the turret of a Mk.IV Churchill. The turret was then cleared and the internal guide ribs for the 6pdr mantlet removed. To accommodate the Sherman mantlet, a large aperture was cut in the front of the Churchill turret. Due to the curvature of the front of the cast Churchill turret it was necessary to rebate the cheeks on either side of the hole to accept the flat flange of the Sherman mantlet. When a satisfactory fit had been achieved the Sherman mantlet, complete with gun, was arc welded into position.<ref name=":0" />

The elevation limits of the gun posed an immediate problem. The mantlet and mount of the Sherman was designed to be set at an angle of some 30 degrees from the vertical. The gun barrel protruded through the mantlet with the elevation being limited by its movement in a slot. The effect of welding the mantlet to the vertical front face of the Churchill turret was to limit resultant maximum elevation to a little over the horizontal whilst permitting a much grater depression than was required. To compensate for this the top of the slot was extended by some 8" with the resulting cut out being welded back into the bottom of the slot.<ref name=":0" />

=== Trails ===
The prototype took ten days to complete after which it was taken to the RAC Training Depot for firing trials. The were performed before the "top flight" of the armoured formations in North Africa, plus several flown in from Italy and elsewhere. The trials were conducted by Major ‘Dick’ Whittington’ a gunnery instructor at the school who also was one of Morrell’s friends. Once he had become accustomed to the gun Whittington was able to target a deserted Arab village at a range of some 8,000 to 8,500 yards, bringing down round after round of HE on top of it. Whittington subsequently commented that he found the Churchill a much more accurate gun platform than the Sherman as it did not 'rock' to the recoil of the gun to anything like the same extent.<ref name=":0" />

The trials were a great success and immediate steps were taken to enable the conversion of further vehicles. The 665 Tank Troop Workshop was moved to Bone and attached to 16 Base Workshop R.E.M.E., where a large tank shop allocated specifically for the conversions. Work proceeded round the clock and in three months to June '44 some 190-200 conversions were produced.<ref name=":0" />

=== Service ===
Upon arrival in Italy the 21st and 25th Tank Brigades were re-structured to include two troops (ie. 18) of Shermans in each Squadron. When the NA75s became available they essentially replaced the Shermans (only 3 or so retained). Within 25th Tank Brigade the North Irish Horse appear to have been the first to recieve NA75s - receiving a full complement of 18 in July 1944. The other two regiments in the brigade received theirs a few weeks later. At this time Vauxhalls were producing MkVIs and MkVIIs Churchills mounting the new QF 75mm, however priority for these vehicles was given to the new front in North West Europe. I've yet to come across any evidence of MkVIs in Italy and it would be until the end of November 1944 that the first few MkVIIs arrived with the Tank Brigades.The NA75 stayed in service with the 25 Tank Brigade until the Brigade was disbanded in January 1945, and with 21 Tank brigade until the end of the war. Whilst we've noted the superior HE perfomance of the the Sheman 75mm it should also be noted that the 6-pdr had a better armour piercing performance coupled with a greater rate of fire. We should also realise that for the tank brigades in Italy at least, up until 1945 when MkVIIs started to be appear in numbers the highest proportion of tanks in the brigades were armed with 6-pdrs.<ref name=":0" />

== Usage in battles ==


The Pbv 301 shall be used mainly as an SPAA. Its cannon with its pinpoint accuracy and a high rate of fire for its BR along the slsgr m/42 HEFI-T belt prove devastating to deal with low-flying planes and bombers. During a game, it is recommended to stay within the confines of your spawn and scout the skies for any aircraft. The high muzzle velocity and rate of fire make this vehicle effective against aircraft at medium ranges.

In an anti-tank role, the Pbv 301 is only effective against light tanks and SPAAGs, as the armour of most tanks at its BR is thick enough to resist 20 mm cannons shells. It is therefore not recommended to play this tank offensively.

=== Pros and cons ===


'''Pros:'''

* Fully-enclosed design, granting the crew a higher chance of survival.
* Equipped with smoke grenades
* Low profile
* Adequate mobility
* Good rate of fire

'''Cons:'''

* Little armour, effective only against machine gun fire
* Only 2 crew members, very low chance of surviving a penetration shot.
* Limited elevation angle
* Long reload time
* Limited belt capacity
* Confined to a strict AA role, inadequate against ground forces

== History ==
The '''pbv 301''' ''(full name is Pansarbandvagn 301)'' it was first built in 1961 and removed from service in 1971 when it was replaced by '''pbv 302.''' It was built on the chassis from the obsolete [https://wiki.warthunder.com/Strv%20m%2F41%20S-II?from=client stridsvagn m/41 tank].

Ostwind II

U55753724: Added a picture of the Ostwind II armour

{{Specs-Card|code=germ_flakpanzer_IV_Ostwind_2}}

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} German self-propelled anti-aircraft gun {{Battle-rating}}. It was introduced in [[Update 1.91 "Night Vision"]], replacing the [[Flakpanzer 341]] in the German tech tree.

The {{PAGENAME}} is an average SPAAG which definitely has nothing to look for on the front line, however, there is a great advantage with its double cannon which becomes extremely dangerous for enemy aircraft which fly within range.

The {{PAGENAME}} has sufficient penetrating power to destroy [[M18 GMC|M18]]s or other light armoured vehicles, however, one should rather concentrate on enemy aircraft. The reasoning behind this is because the turret is open from above and weakly armoured on the sides and is vulnerable to enemy aircraft fire and the .50 calibre machine guns on vehicles such as the [[M2HB (12.7 mm)|M2HB]] vehicle.

== General info ==
=== Survivability and armour ===
[[File:Ostwind II armour.jpg|alt=Ostwind II armour|thumb|533x533px]]

The frontal hull armour (80 mm) is quite well protected against small-calibre weapons and [[M2HB (12.7 mm)|.50 caliber BMG]]s, the sides (30 mm) and rear (20 mm) are not as well protected.

The turret is open at the top and has a rectangular recess in the right, frontal turret armour, because of the optics.

In addition, the steel of the turret (25 mm) is very weakly armoured, as well as the hull roof (10-12 mm).

Since the vehicle has a crew of five, it usually survives the first attack from enemy aircraft (because of the driver and the machine gunner(/radio operator) in the hull), as well as a shot into the turret.

=== Mobility ===


The vehicle does not have that great average speed, which means that the 39 km/h will be rare on the battlefield. Forget about trying to turn on the spot as this vehicle does not have neutral steering. Even worse is attempting to use the reverse gear (-7km/h) is extremely insufficient presenting an easy target if having to back out of a tight situation.

== Usage in battles ==


;Realistic Battles

The {{PAGENAME}} should be held in reserve towards the end of the game when there tends to be a significant amount of enemy aircraft flying. It is best to avoid the front lines or beating feet toward the enemy tanks as the {{PAGENAME}} tends to be an easy target for a majority of the other tanks in the game.

If your own team is about to lose or it gets very exciting towards the end and there are no many enemies left alive, you can place your {{PAGENAME}} inside an allied capture-point to defend it from enemy light tanks. Due to the location, it is more central to the battlefield and presents a difficult challenge for enemy aircraft to attempt to fly over.

=== Pros and cons ===


'''Pros:'''

* 2 x 3.7 cm FlaK 44 cannons
* Does not need to reload until it is completely out of ammunition
* Enough penetration to destroy enemy light armoured vehicles

'''Cons:'''

* Built on Panzer IV chassis and is a contemporary of it
* Quite slow average speed
* Inadequate penetration against many enemy vehicles (best against aircraft)

== History ==


The Ostwind II was a development of the [[Ostwind]]. First conceived as early as October 1943, the Ostwind II saw the single 3.7 cm FLaK 43 replaced by a twinned 3.7 cm FLaK Zwilling 44 built by the ''Gustloff-Werke'' in Suhl. One single prototype was delivered to the ''Panzerflak-Ersatz und Ausbildungsabteilung Ohrsdurf/Thühringen'' in January of 1945 for evaluation purposes, but due to the rapid events of the war it was never taken into production.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} German Self-Propelled Anti-Aircraft (SPAA) vehicle {{Battle-rating}}.
== General info ==
=== Survivability and armour ===
''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?''

''If necessary use a visual template to indicate the most secure and weak zones of the armour.''

=== Mobility ===
''Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability as well as the maximum speed forwards and backwards.''

== Armaments ==
=== Main armament ===
''Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibilty of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.''

=== Additional armament ===
''Some tanks are armed with several guns in one or more turrets. Evaluate the additional weaponry and give advice on its use. Describe the ammunition available for additional weaponry. Give advice on how to use them and how to fill the ammunition storage. If there is no additional weaponry remove this subsection.''

=== Machine guns ===
''Offensive and anti-aircraft machine guns not only allow you to fight some aircraft but also are effective against lightly armoured vehicles. Evaluate machine guns and give recommendations on its use.''

== Usage in the battles ==
''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

=== Pros and cons ===
''Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Do not use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".''

'''Pros:'''

* Never need to reload
* Very little lead required to hit enemy aircraft
* Reasonable rate of fire for the calibre (37 mm)
* A single hit often cripples or completely destroys an enemy aircraft
* An M18's worst nightmare
* Rather difficult to kill with one shot
* Turret is better armoured than the Wirbelwind

'''Cons:'''

* Based on the chassis of a 4.0 tank; here the armour lacking and is slow moving
* A viewing port in the turret allows enemies to kill the gunner with machine gun fire
* Open turret; susceptible to aerial gunfire or bomb blast shrapnel
* Significantly harder to hit and kill an enemy aircraft when compared to the Wirbelwind
* Pz. Gr. belt no longer has 65 mm of penetration; combat ability is debatably worse than the Wirbelwind

== History ==
''Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the <code>main</code> template. Be sure to include links to sources at the end of the article.''

=== In-game description ===
A development of the Wirbelwind project. The goal of the Ostwind project was to increase the unit’s firepower, protection, and effective range. For this purpose, a 3.7 cm FlaK 43 anti-air gun was installed on it, and its turret’s armor was increased to 25 mm. The first prototype was completed in September, 1944. In the same month, on the 23rd, it was used in combat operations on the Eastern Front. Between 1944 and 1945 Ostbau-Sagan released 43 mounts. They were more effective than their predecessors had been.

== History ==

=== Amount ===
A single prototype was built by Ostbau in January-February 1945, but the Ostwind II never entered production.

=== Name origin ===
There are several names given to this vehicle, which include Flakpanzerkampfwagen IV 3.7 cm Flak 43, Leichte Flakpanzer mit 3.7 cm Flak 43 auf Panzerkampfwagen IV or, much simpler, Flakpanzer IV/3.7 cm. It is most well-known today under its Ostwind nickname and this is very common in many sources. The origin or even if it was an original German designation is not clear, as none of the sources give a specific explanation of the origin of this name. This article will use the Ostwind name mostly for simplicity but also because of its common use in the literature.

=== requirements given ===

* The turret should be fully traversable (360°)
* The new turret should have three or four crew members
* The crew operating the anti-aircraft gun should be well protected and it should be open-topped so as to give the crew a better view of the skies and because of the smoke produced by the guns
* The turret traverse mechanism should be simple
* The main weapon should have a minimum effective range of 2000 m, with enough ammunition to operate efficiently in a combat situation
* The height must be lower than 3 m
* Radio equipment
