The '''{{Specs|name}}''' is a Rank {{Specs|rank}} French fighter {{Battle-rating|5}}.. It was introduced in [[Update 1.75 "La Résistance"]].
+
In the early 1930s, the Curtiss-Wright Corporation began a private venture to build a fighter aircraft which was a revolutionary departure from earlier cloth-covered biplanes of World War I. This project aircraft under development was named the Curtiss Hawk Model 75 (later it would be known by P-36 Hawk, Hawk-75 – or just H-75 and Mohawk.) The P-36 was an all-metal monoplane (although the control surfaces were fabric-covered) with a 900 hp radial engine, enclosed cockpit, and retractable landing gear. Early fighter trials paired this fighter against the Seversky P-35A where it ultimately lost out.
 +
 
 +
Around the time of the late 1930s, the French Air Force was lacking in modern fighter aircraft and realized that the domestic production could not meet the needs of the country. In light of this, France looked to foreign producers and approached Curtiss to produce an export version of the P-36 (which they were excited about), which would be known as the H-75. The first contract purchase was dubbed H-75A-1, of which 100 were contracted for. In December 1938, the H-75A-1 fighters were routed to France where they were assembled and where minor changes were made, especially in regards to the armament, cockpit controls, and cockpit instruments.
 +
 
 +
As the geopolitical situation rapidly disintegrated in Europe, France pushed for a rush order for 100 Curtiss H-75A-2 versions. This model was an improvement over the A-1, specifically in regards to its additional weaponry and an improved motor. After the declaration of war with Germany, the French placed another order for the H-75A-3 versions of the aircraft, first arriving in March 1940. However, due to the German invasion of France, some of the shipment was sunk at sea, while the others were diverted to areas around North Africa for safekeeping. Similar to the A-3, the H-75A-4 only had a relatively small amount arrive in France, with the bulk of them being diverted to Great Britain as Mohawks.
 +
 
 +
The French H-75 aircraft continued to see combat throughout the war, both under the control of the Allied Free French Forces and the British and under the axis Finnish, who received captured French aircraft from the Germans to be used against the Soviets.
  
The H-75 is an all-round very effective fighter in War Thunder. It has an excellent turn rate and its top speed of 560 km/h at low altitude is very impressive, as it can outrun most of its competitors. Its fiercest opponent is the [[Bf 109 E-1|Bf 109]], against which it loses most notably in the climbing department. To survive against these in realistic battles and simulator battles, it is important not to use WEP outside of combat, as whereas WEP itself is infinite, the plane's cooling capacity is not – attentive pilots will notice that it decreases with time if they push WEP too hard — at the beginning of a fly out, the H-75 A-1's engine will only show signs of overheating at 235ºC(455ºF), whereas after pushing WEP too hard, the engine will begin to struggle at 225ºC. Engine management is as such one of the crucial skills for mastering this plane. With the engine weakened from overheating, a player will find it hard to beat a Bf 109 if in an energy disadvantage. With a healthier engine, the pilot can keep the engine roaring at full power so as to endure sustained maneuvering without eventually stalling and dropping like a rotten apple from a tree.

! colspan="8" | Characteristics

The {{PAGENAME}} is a relatively easy fighter aircraft to fly and requires only a relatively short space to both take-off and land. Due to the fantastically low wing loading rate of 23.9 lb/ft<sup>2</sup><ref name="JoeB" />, this fighter is an excellent turning aircraft and, accompanied by a strong rudder, can spiral climb easily, especially during WEP cycles. This aircraft has the advantage of being both a turn fighter and a Boom & Zoom fighter, all depending on the situation, type of enemy aircraft, and mission type. The {{PAGENAME}} will out-turn many fighters of its rank and can prove difficult to follow if attempting to shoot it down. The [[P-36A]], [[P-36C|P-36C,]] and {{PAGENAME}} utilise the same engine, however with the extra two machine guns and associated ammunition, the {{PAGENAME}} model lags slightly behind the A with flight characteristics. The difference is often not noticeable enough for the pilot to realize while manoeuvring the aircraft. The trade-off for more guns vs. a slightly hampered flight model is well worth it.

As with many early pre-war fighters, not much emphasis was put on the survivability of the aircraft. The best course of action was for the pilot to not let anyone get behind them. The {{PAGENAME}}'s only sources of protection for the pilot is the engine block and the 9.5 mm steel plate (angled at 24° for the effective thickness of 13 mm). Given that there is no frontal armour, the engine block may be used to save the pilot at the expense of the engine, thus requiring the pilot to glide back to base if possible or to bailout. There are also two unprotected oil coolers which, if punctured, will cause the aircraft will leak oil until depleted eventually causing the engine to seize up.

The four machine guns are arranged with two wing-mounted and the other two mounted in the nose of the aircraft. The wing mounted and nose mounted guns have differing amounts of ammunitions, which means that the nose guns will continue to fire after the wing mounted guns become empty.
+
Lacking the punch of the 12.7 mm, this fighter has to make do without the more powerful machine gun. Due to the wing-mounted machine guns, convergence is a factor to deal with with the optimal range being 100 - 200 m. Anything beyond this will still work, but the bullets significantly start losing their punch. The increase in armament increased the damage output ability of the fighter. Options in ammunition will allow the pilot to select the type best suited for their mission whether it be as an interceptor, ground target hunter, or a stealthy pounce aircraft.

+
* Universal rounds for the French aircraft have the most armour-piercing rounds coupled with tracer bullets than any other belt. The tracer rounds are important because of the ability to walk in the shots with the tracers (especially helpful in realistic and simulator battles where the aiming helper is not available for use) to the enemy aircraft.

Its quick firing streams of low-calibre bullets are not to be underestimated, especially given the agility of the plane, as it is easy to get critical bursts of bullets into vital parts of the enemy's vehicle. In general, what it can't outrun it can out-turn, which means that it will be very hard for enemies to shake it off once it gets on their tail. Do mind that to not engage fighters head-on, as the wing-mounted, low calibre weapons aren't well suited for that sort of engagement. Exceptions include particularly vulnerable and poorly armed fighters, such as most [[:Category:Biplanes|Biplanes]]. With bombers, the story is different, engaging them head-on and firing at the cockpit is a good way to score a pilot snipe.

That it can out-turn many planes is not an excuse to engage in fancy maneuvers whenever the chance presents itself — even the best turner will tire itself out and become easy prey if it doesn't watch its speed and altitude. Be clever with who to engage — if faced with two well turning fighters like the [[CR.42]] and one fast fighter like the [[He 100 D-1]], engage the faster one first so that the {{PAGENAME}} don't end up sandwiched between an aircraft that can out-turn it and an aircraft that can outrun it. This is of course not a rule set in stone, but these are the decisions that should be consciously assessed before engaging. If thinking through these decisions rationally and with a cool-head (who to engage, climbing, diving, or going in a straight line, etc.) a pilot could see the great potential of this aircraft.

Energy retention lends this fighter to be a great zoomer, dropping in for a shot and then speeding back up to regain the energy advantage. With this aircraft having such a low stall speed; it makes a great fighter to practice rope-a-dope energy depletion manoeuvres. This requires the H-75-A1 pilot to bait another fighter into following them in a climb. As the attacker attempts to get guns on target, the pilot can start to spiral climb, causing the attacking aircraft to pull a tighter circle, hemorrhaging their energy. If done correctly, the attacking fighter will stall out and be completely helpless as they begin to fall back to the ground, allowing the H-75A-1 to roll over or Split-S and take out the stalled fighter below.
  
===Modules===
+
Most fighters are typically only good at one thing, whether it's turning, speed, or weapon systems. However, the {{PAGENAME}} is good at two: speed and turning. This fighter has the ability to not only zoom attack but also turn fight competitively with most other aircraft. There are few aircraft (notably the A6M Zero fighters of the Imperial Japanese Navy or the Bf 109 of the German Luftwaffe) which may outshine while turning or climbing. However, when utilizing flaps and rudder while turning, the {{PAGENAME}} can manoeuvre into some tight turns and gain a possibility to take down these foes.
{| class="wikitable"
+
 
! Tier
+
Even with all of its power and mobility, the {{PAGENAME}} is a relatively fragile aircraft. Without much armour, many of its critical systems are exposed and it will not take much, even from lower calibre machine guns, to cause fuel fires, oil leaks, and engine shutdowns, not to mention a knocked out pilot. Situational awareness is critical to potentially know not only where the targets are, but also the enemy aircraft which are manoeuvring into position and ready to pounce. The weakness of having such weak machine guns will require the pilot to get in close (50 – 200 m) to make the most of their shots count, as anywhere past 150 m, bullet penetration drops off considerably.

The P-36 Hawk began its life at Curtiss Aeroplane Company as a design in the early 1930s. A private venture by Curtiss, the project was headed up by Donovan A. Berlin, a former Northrop aircraft company engineer who was the principal designer and incorporated design portions of early Northrop designs.<ref name="MilFac" /> The P-36, at this time known as the X-17Y, was a stretch from the biplane years by utilizing an all-metal low-wing monoplane with fabric-covered control surfaces. This aircraft also featured retractable landing gear, which utilized a design put forward by Boeing Aircraft Company and required royalties to be paid to Boeing for every aircraft in which this landing gear was installed.<ref name="JoeB" /><ref name="AviHis" /> Initial weapon load-outs included the standard 12.7 mm and 7.62 mm machine guns, both of which were mounted in the forward fuselage deck and fired through openings in the cowling, synchronized to fire through the propeller arc.<ref name="AviHis" />
 +
 
 +
The initial flight took place in 1935 and when it was presented at a competition the next year, the competitor aircraft (Seversky SEV-2XP/P-35) was heavily damaged in transit. While Seversky took their aircraft back to perform repairs and modifications, Curtiss took the opportunity during this time to make some modifications of their own, and namely replacing the Wright XR-1670-5 twin-row air-cooled radial engine with the upgraded Write XR-1820-39 Cyclone radial.<ref name="MilFac" /> With the Seversky aircraft repaired, the competition was back on. Even though the Seversky aircraft underperformed and was more expensive than Curtis X-17Y, it was selected and an order of 77 aircraft were put in for, however later the Material Division of the USAAC contacted Curtis and put in an order for three examples as they were becoming nervous about Seversky's ability to deliver their aircraft on time. Curtiss worked on modifying the P-36 by again upgrading the motor and working on the cockpit, especially increasing the amount of area behind the cockpit where the pilot could see. During the 1937 competition, test pilots who piloted the P-36 all commented that the aircraft responded to pilot input favourable and at all speeds and even noted that it handled well on the ground while taxiing. With such a reaction from the test pilots, the USAAC put in an order for 210 P-36A fighters, which at that time was the largest single US military aircraft order since World War I.<ref name="JoeB" />
 +
 
 +

Description

The H-75A-1 is a rank I French fighter with a battle rating of 1.3 (AB) and 1.7 (RB/SB). It was introduced in Update 1.75 "La Résistance".

In the early 1930s, the Curtiss-Wright Corporation began a private venture to build a fighter aircraft which was a revolutionary departure from earlier cloth-covered biplanes of World War I. This project aircraft under development was named the Curtiss Hawk Model 75 (later it would be known by P-36 Hawk, Hawk-75 – or just H-75 and Mohawk.) The P-36 was an all-metal monoplane (although the control surfaces were fabric-covered) with a 900 hp radial engine, enclosed cockpit, and retractable landing gear. Early fighter trials paired this fighter against the Seversky P-35A where it ultimately lost out.

Around the time of the late 1930s, the French Air Force was lacking in modern fighter aircraft and realized that the domestic production could not meet the needs of the country. In light of this, France looked to foreign producers and approached Curtiss to produce an export version of the P-36 (which they were excited about), which would be known as the H-75. The first contract purchase was dubbed H-75A-1, of which 100 were contracted for. In December 1938, the H-75A-1 fighters were routed to France where they were assembled and where minor changes were made, especially in regards to the armament, cockpit controls, and cockpit instruments.

As the geopolitical situation rapidly disintegrated in Europe, France pushed for a rush order for 100 Curtiss H-75A-2 versions. This model was an improvement over the A-1, specifically in regards to its additional weaponry and an improved motor. After the declaration of war with Germany, the French placed another order for the H-75A-3 versions of the aircraft, first arriving in March 1940. However, due to the German invasion of France, some of the shipment was sunk at sea, while the others were diverted to areas around North Africa for safekeeping. Similar to the A-3, the H-75A-4 only had a relatively small amount arrive in France, with the bulk of them being diverted to Great Britain as Mohawks.

The French H-75 aircraft continued to see combat throughout the war, both under the control of the Allied Free French Forces and the British and under the axis Finnish, who received captured French aircraft from the Germans to be used against the Soviets.

The H-75A-1 is a relatively easy fighter aircraft to fly and requires only a relatively short space to both take-off and land. Due to the fantastically low wing loading rate of 23.9 lb/ft2[1], this fighter is an excellent turning aircraft and, accompanied by a strong rudder, can spiral climb easily, especially during WEP cycles. This aircraft has the advantage of being both a turn fighter and a Boom & Zoom fighter, all depending on the situation, type of enemy aircraft, and mission type. The H-75A-1 will out-turn many fighters of its rank and can prove difficult to follow if attempting to shoot it down. The P-36A, P-36C, and H-75A-1 utilise the same engine, however with the extra two machine guns and associated ammunition, the H-75A-1 model lags slightly behind the A with flight characteristics. The difference is often not noticeable enough for the pilot to realize while manoeuvring the aircraft. The trade-off for more guns vs. a slightly hampered flight model is well worth it.

  • 9.5 mm steel plate behind the pilot.

As with many early pre-war fighters, not much emphasis was put on the survivability of the aircraft. The best course of action was for the pilot to not let anyone get behind them. The H-75A-1's only sources of protection for the pilot is the engine block and the 9.5 mm steel plate (angled at 24° for the effective thickness of 13 mm). Given that there is no frontal armour, the engine block may be used to save the pilot at the expense of the engine, thus requiring the pilot to glide back to base if possible or to bailout. There are also two unprotected oil coolers which, if punctured, will cause the aircraft will leak oil until depleted eventually causing the engine to seize up.

Armaments

Offensive armament

Ammunition2 200 rounds
Fire rate1 000 shots/min

The H-75A-1 is armed with:

  • 2 x 7.5 mm Mle 38 machine guns (600 rpg = 1,200 total)
  • 2 x 7.5 mm Mle 38 machine guns (500 rpg = 1,000 total)

Lacking the punch of the 12.7 mm, this fighter has to make do without the more powerful machine gun. Due to the wing-mounted machine guns, convergence is a factor to deal with with the optimal range being 100 - 200 m. Anything beyond this will still work, but the bullets significantly start losing their punch. The increase in armament increased the damage output ability of the fighter. Options in ammunition will allow the pilot to select the type best suited for their mission whether it be as an interceptor, ground target hunter, or a stealthy pounce aircraft.

Option 1 Configuration (optimal 200 - 400 m convergence)
  • 7.5 mm x 4 = Universal rounds
  • Universal rounds for the French aircraft have the most armour-piercing rounds coupled with tracer bullets than any other belt. The tracer rounds are important because of the ability to walk in the shots with the tracers (especially helpful in realistic and simulator battles where the aiming helper is not available for use) to the enemy aircraft.

This aircraft does not have the option to select any additional suspended armaments nor does it have any defensive weapons to counter any attackers.

Usage in battles

Energy retention lends this fighter to be a great zoomer, dropping in for a shot and then speeding back up to regain the energy advantage. With this aircraft having such a low stall speed; it makes a great fighter to practice rope-a-dope energy depletion manoeuvres. This requires the H-75-A1 pilot to bait another fighter into following them in a climb. As the attacker attempts to get guns on target, the pilot can start to spiral climb, causing the attacking aircraft to pull a tighter circle, hemorrhaging their energy. If done correctly, the attacking fighter will stall out and be completely helpless as they begin to fall back to the ground, allowing the H-75A-1 to roll over or Split-S and take out the stalled fighter below.

Most fighters are typically only good at one thing, whether it's turning, speed, or weapon systems. However, the H-75A-1 is good at two: speed and turning. This fighter has the ability to not only zoom attack but also turn fight competitively with most other aircraft. There are few aircraft (notably the A6M Zero fighters of the Imperial Japanese Navy or the Bf 109 of the German Luftwaffe) which may outshine while turning or climbing. However, when utilizing flaps and rudder while turning, the H-75A-1 can manoeuvre into some tight turns and gain a possibility to take down these foes.

Even with all of its power and mobility, the H-75A-1 is a relatively fragile aircraft. Without much armour, many of its critical systems are exposed and it will not take much, even from lower calibre machine guns, to cause fuel fires, oil leaks, and engine shutdowns, not to mention a knocked out pilot. Situational awareness is critical to potentially know not only where the targets are, but also the enemy aircraft which are manoeuvring into position and ready to pounce. The weakness of having such weak machine guns will require the pilot to get in close (50 – 200 m) to make the most of their shots count, as anywhere past 150 m, bullet penetration drops off considerably.

Pros and cons

Pros:

  • High climb rate, especially with war emergency power applied
  • Impressive roll and turn rate, allowing for highly efficient Immelman and split-S manoeuvres
  • Strong rudder, excels in wing-over and hammerhead stall manoeuvres
  • Slow stall speed (about 55 mph or 88.5 km/h)
  • Four machine guns (comparable to P-36C)

Cons:

  • Armament is inadequate against bombers and other aircraft with rear-facing gunners
  • Lack of adequate armour renders engine, fuel tanks, oil coolers and virtually defenceless

History

The P-36 Hawk began its life at Curtiss Aeroplane Company as a design in the early 1930s. A private venture by Curtiss, the project was headed up by Donovan A. Berlin, a former Northrop aircraft company engineer who was the principal designer and incorporated design portions of early Northrop designs.[2] The P-36, at this time known as the X-17Y, was a stretch from the biplane years by utilizing an all-metal low-wing monoplane with fabric-covered control surfaces. This aircraft also featured retractable landing gear, which utilized a design put forward by Boeing Aircraft Company and required royalties to be paid to Boeing for every aircraft in which this landing gear was installed.[1][3] Initial weapon load-outs included the standard 12.7 mm and 7.62 mm machine guns, both of which were mounted in the forward fuselage deck and fired through openings in the cowling, synchronized to fire through the propeller arc.[3]

The initial flight took place in 1935 and when it was presented at a competition the next year, the competitor aircraft (Seversky SEV-2XP/P-35) was heavily damaged in transit. While Seversky took their aircraft back to perform repairs and modifications, Curtiss took the opportunity during this time to make some modifications of their own, and namely replacing the Wright XR-1670-5 twin-row air-cooled radial engine with the upgraded Write XR-1820-39 Cyclone radial.[2] With the Seversky aircraft repaired, the competition was back on. Even though the Seversky aircraft underperformed and was more expensive than Curtis X-17Y, it was selected and an order of 77 aircraft were put in for, however later the Material Division of the USAAC contacted Curtis and put in an order for three examples as they were becoming nervous about Seversky's ability to deliver their aircraft on time. Curtiss worked on modifying the P-36 by again upgrading the motor and working on the cockpit, especially increasing the amount of area behind the cockpit where the pilot could see. During the 1937 competition, test pilots who piloted the P-36 all commented that the aircraft responded to pilot input favourable and at all speeds and even noted that it handled well on the ground while taxiing. With such a reaction from the test pilots, the USAAC put in an order for 210 P-36A fighters, which at that time was the largest single US military aircraft order since World War I.[1]

As the P-36 fighters began to roll off the assembly line, they were shipped to US squadrons, however, problems developed with the aircraft which left them grounded while waiting repairs. The P-36 continued to have problems, however, four P-36A fighters stationed at Wheeler Air Field in Hawaii were able to get airborne and attach a flight of Nakajima B5N1 torpedo bombers, claiming two shot down and gaining the first US fighter aircraft "kills" of the Pacific War. Despite this action, the P-36 fighters were withdrawn from combat outfits and sent to training units for new pilots to train on. While the P-36 did not see much action with the U.S., it did see combat action while flown by other nations such as France and Finland where they put the little fighter to the test and were highly successful with it. 10 P-36A training fighters were transferred in 1942 to Brazil where they remained in service until 1954.[1]

While the P-36 failed to initially secure a contract early on with the United States, the desperate French approached Curtiss to secure an export version of this fighter to beef up their armed forces. With a contract settled, the H-75A-1 was the first production batch of Hawk 75 aircraft built for France with around 100 built and delivered. Unfortunately, after hostilities began, many of these aircraft were captured during the fall of France and were shipped to other countries friendly with Germany and were considered challenging aircraft for the allies to fly against.
