Particulars, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such full impunity than the SR-71, the world’s quickest jet-propelled aircraft. The Blackbird’s efficiency and operational achievements placed it at the pinnacle of aviation technologies developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time for the duration of 24 years of active service with the U.S. Air Force. On its last flight, March six, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (two,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane more than to the Smithsonian.

The Type 95 Ha-Gō (九五式軽戦車 ハ号 Kyugoshiki keisensha Ha-Gō?) (also known as the Variety 97 Ke-Go) was a light tank employed by the Imperial Japanese Army in combat operations of the Second Sino-Japanese War and the Second World War. Despite the fact that it was really slow for a light tank, it proved sufficient against opposing infantry in campaigns in Manchuria and China, as the Chinese National Revolutionary Army had really couple of tanks or anti-tank weapons to oppose them. Nevertheless, the Kind 95 lacked the armor or armament of contemporary Allied tanks, and was regarded as obsolete by the begin of Planet War II. Much more than two,000 units were made. It was also employed by Imperial Japanese Navy SNLF detachments in Pacific locations in the course of conflict.
History and improvement

From early 1930s, the Japanese army started experimenting on a mechanized warfare unit combining infantry with tanks. Even so, the Variety 89 Medium tank could not hold pace with the motorized infantry, which could move at 40 km/h by truck. To solve this dilemma, the Army Technical Bureau proposed a new light tank at 40 km/h speed and began improvement in 1933. The prototype of the new tank was finished in 1934 at the Army’s Sagami Arsenal. It was a higher-speed and lightly-armored tank equivalent to the British cruiser tank or Soviet BT tank. Its code name was &quotHa-Gō&quot (ハ号) designated that it was the &quotthird kind&quot of tank created.[three]

In 1935, a meeting was held at the Army Technical Bureau, at which time, the Variety 95 was presented as a prospective principal battle tank for mechanized infantry units. The infantry had issues that the armor was not thick adequate for enough infantry assistance even so, the cavalry indicated that the improved speed and armaments compensated for this thin armor. In the end, the infantry agreed, as the Sort 95 was still superior to the only obtainable option, which was the armored automobile.

Production was started in 1935 by Mitsubishi Heavy Industries. By 1939, one hundred units had been constructed. Mitsubishi would go on to develop a total of 853 in their personal factories, with an additional 1250 units built by the Sagami Arsenal, Hitachi Industries, Niigata Tekkoshō, Kobe Seikoshō, and Kokura Arsenal.[two]

The Sort 95 was a major improvement more than the Japanese Army’s prior light tanks and tankettes, but was quickly involved in an intensive plan to create improved variants such as the Manshū model (Kind M), the Ha-Gō’s direct descendant. Variety M was technically identical but created for use in the Kwantung Army’s tank schools in Manchukuo and it was planned to be supplied in far a lot more numbers to future Manchukuo Imperial Army armored units and was projected to be manufactured in that nation.

Another development was the Kind 98 Ke-Ni light tank that entered production in 1942 of which 200 autos have been built. This derivitative was better armored and carried an armament comprising one particular Sort one hundred 37 mm gun and two 7.7 mm machine guns.

The Sort 95 also served as the basis of the Variety two Ka-Mi amphibious tank which gave good service in Japan’s early campaigns of Planet War II.

[edit]
Design and style

The Kind 95 was a 7.4-ton vehicle with a complement of 3 crewmen (generally a commander/gunner/loader, mechanic/bow machine gunner, and a driver).

The major armament was one particular Type 94 37 mm Tank Gun with 37 mm caliber, barrel length of 1.3585 meters (L36.7) (early model), 1.358 meters (L36.7) (late model), el angle of fire -15 to +20 degrees (early model), -15 to +20 degrees (late model), AZ angle of fire of 20 degrees (early model) 20 degrees (late model), muzzle velocity: 600 m/s (early model), 700 m/s (late model), penetration: 45 mm/300 m (early model) 25 mm/500 m (late model) utilized by the Variety 95 Light Tank. The commander was accountable for loading, aiming, and firing the primary gun, The Variety 95 tank carried two sorts of ammunition, Variety 94 higher-explosive and Kind 94 armor-piercing.

Secondary armament consisted as two Type 91 six.5mm machine guns, 1 mounted in the hull and the other in the turret facing to the rear. Trial use in Manchukuo and China confirmed that far better armament was desirable and the 6.5mm machine guns had been exchanged for far more effective 7.7mm Kind 97 light machine guns on the proper hand side, for use by the currently overworked commander/gunner in 1941. The original Kind 94 principal gun was also replaced with a Sort 98 weapon of the very same caliber but with a larger muzzle velocity.

The hand-operated turret was tiny and incredibly cramped for even the 1 crewman typically located there (the commander), and was only getting in a position to rotate in a 45 degree forward arc, leaving the back to be covered by the rear-facing machine gun which failed to compensate for this significant disadvantage.

The most characteristic function of the Sort 95 tank was its simple suspension method. The tracks had been driven through the front sprocket. Two bogie wheels had been suspended on a single bell crank with two bell cranks per side. There had been two return wheels. The suspension had troubles early on with a tendency to pitch so badly on rough ground that the crew occasionally located it impossible to drive at any speed, and so it was modified with a brace to connect the pairs of bogies. Regardless of this, the tank continued to give its customers a rough ride across any uneven ground, and was offered with an interior layer of asbestos, helpful in minimizing interior heat and guarding the crew from injury when the tank moved at high speed across rough terrain.[three]

This very first production models used one particular 110 hp (82 kW) Mitsubishi air cooled diesel engine with a top speed of 25 mph (40 km/h). This was the identical engine that equipped the Sort 89 I-Go medium tank. Later the far more potent engine Mitsubishi NVD 6120 with 120 hp (89.five kW) was installed.[3] Some Variety 95 were fitted with two reflectors in the front of the vehicle for evening operations.

Kind five Ho-Ru 47 mm self-propelled gun
The Ho-Ru was a light tank destroyer equivalent to the German Hetzer. The improvement of the Kind 5 Ho-Ru began in February 1945. The Type five Ho-Ru utilized the chassis of the Type 95 Light Tank, but its suspension was enlarged to 350 mm track hyperlink width. The wheel guide pins were set in two rows to hold a road wheel among them. The sprocket of the driving wheel was the grating kind to gear with the wheel guide pins like on the Soviet T-34. It was armed with one particular 47 mm main gun.
Sort 98 Ke-Ni light tank
This final modification was somewhat lighter than the original Sort 95, even with its heavier (.62 inch) armor. It entered production in 1942, but only about 200 were manufactured.

Combat history

When the Variety 95 entered service in 1935 it was a capable machine and comparable to any modern light tank in the planet. It was the very best automobile of its category available to the Japanese forces in any numbers from the 1930s to World War II, and was used mainly to assistance infantry or as cavalry reconnaissance and, to a lesser extent, as raiding vehicles. It could compete with the American M3 light tanks on the Philippines, even though the British had very handful of tanks of any variety in Malaya or Burma in December 1941. [four]

The Type 95 Ha-Gō proved moderately profitable for the duration of the early campaigns of late 1941 and early 1942, when Japanese forces overran British Malaya and seized the fortress city of Singapore. A single crucial to the Japanese good results in Malaya was the unexpected presence of their tanks in locations exactly where the British did not think tanks could be employed. The wet jungle terrain did not turn out to be an obstacle twelve Sort 95s took portion in the attack which broke the Jitra line on 11 December 1941.

The very first tank-vs-tank battles of the war was on 22 December 1941 for the duration of the Japanese invasion of the Philippines. Type 95s of the 4th Tank Regiment clashed with M3s of the American 192nd Tank Battalion. Each tanks have been armed with a 37 mm gun, and the M3 was far better armored however, the inexperienced American commanders failed to make very good use of their tanks.

Two Sort 95 tanks have been deployed to assistance the Japanese landing at Milne Bay, late August 1942. Initially, the tanks proved profitable against the lightly armed Australian infantry, whose ‘sticky bombs’ failed to stick due to the humidity. Even though the tanks had proved dependable in the tropical conditions of Malaya, they could not deal with the volume of mud brought on by intense, practically everyday rainfall at Milne Bay. Both tanks had been bogged down and abandoned a couple of days after the landing.

The Type 95 very first started to show its vulnerability during later battles against British/Commonwealth forces, where the tank’s 37mm gun could not penetrate the armor of the British Matilda tanks which had been deployed against them. The thin armor of the Type 95 created it increasingly vulnerable as Allied forces realized that common infantry weapons have been capable of penetrating the minimal armor around the engine block, and even its thickest armor could not withstand something above rifle caliber. Its firepower was insufficient to take on other tanks such as the medium M4 Sherman or the M3 Stuart light tanks. [four]

As the tide of the war turned against Japan, the Kind 95s have been growing expended in banzai charges or had been dug-in as pillboxes in static defense positions in the Japanese-occupied islands. Throughout the Battle of Tarawa, seven entrenched Kind 95th opposed American landings. More were destroyed on Parry Island and on Eniwetok. On Saipan, Type 95s attacked the American Marine beachhead on 16 June 1944 and much more have been utilized in the largest tank battle in the Pacific the following day.

In the Battle of Guam on 21 July, ten Kind 95 had been lost to bazooka fire or M4 tanks. Seven far more have been destroyed on Tinian on 24 July, and 15 more on Battle of Peleliu on 15 September. Likewise, in the Philippines, at least ten Sort 95s have been destroyed in different engagements on Leyte, and one more 19 on Luzon. At the Battle of Okinawa, 13 Type 95s and 14 Variety 97 Shihoto medium tanks of the 27th Tank Regiment faced 800 American tanks.

When the war ended hundreds of Type 95s have been left in China. They were used during the Chinese Civil War and by the People’s Liberation Army of the People’s Republic of China in the course of the Korean War.

The Kind 95 Ha-Gō proved moderately effective in the course of the early campaigns of late 1941 and early 1942, when Japanese forces overran British Malaya and seized the fortress city of Singapore. One particular key to the Japanese accomplishment in Malaya was the unexpected presence of their tanks in locations exactly where the British did not think tanks could be employed. The wet jungle terrain did not turn out to be an obstacle twelve Type 95s took part in the attack which broke the Jitra line on 11 December 1941.

The very first tank-vs-tank battles of the war was on 22 December 1941 during the Japanese invasion of the Philippines. Kind 95s of the 4th Tank Regiment clashed with M3s of the American 192nd Tank Battalion. Both tanks were armed with a 37 mm gun, and the M3 was far better armored nevertheless, the inexperienced American commanders failed to make great use of their tanks.

Two Variety 95 tanks have been deployed to support the Japanese landing at Milne Bay, late August 1942. Initially, the tanks proved profitable against the lightly armed Australian infantry, whose ‘sticky bombs’ failed to stick due to the humidity. Though the tanks had proved trustworthy in the tropical circumstances of Malaya, they could not deal with the volume of mud triggered by intense, virtually daily rainfall at Milne Bay. Each tanks had been bogged down and abandoned a couple of days soon after the landing.

The Variety 95 very first began to show its vulnerability during later battles against British/Commonwealth forces, exactly where the tank’s 37mm gun could not penetrate the armor of the British Matilda tanks which were deployed against them. The thin armor of the Sort 95 produced it increasingly vulnerable as Allied forces realized that common infantry weapons have been capable of penetrating the minimal armor about the engine block, and even its thickest armor could not withstand anything above rifle caliber. Its firepower was insufficient to take on other tanks such as the medium M4 Sherman or the M3 Stuart light tanks. [four]

As the tide of the war turned against Japan, the Sort 95s had been rising expended in banzai charges or had been dug-in as pillboxes in static defense positions in the Japanese-occupied islands. In the course of the Battle of Tarawa, seven entrenched Kind 95th opposed American landings. More were destroyed on Parry Island and on Eniwetok. On Saipan, Kind 95s attacked the American Marine beachhead on 16 June 1944 and a lot more were employed in the biggest tank battle in the Pacific the following day.

In the Battle of Guam on 21 July, ten Variety 95 had been lost to bazooka fire or M4 tanks. Seven more had been destroyed on Tinian on 24 July, and 15 far more on Battle of Peleliu on 15 September. Likewise, in the Philippines, at least ten Variety 95s had been destroyed in a variety of engagements on Leyte, and an additional 19 on Luzon. At the Battle of Okinawa, 13 Kind 95s and 14 Variety 97 Shihoto medium tanks of the 27th Tank Regiment faced 800 American tanks.

When the war ended hundreds of Variety 95s had been left in China. They had been utilized throughout the Chinese Civil War and by the People’s Liberation Army of the People’s Republic of China for the duration of the Korean War.

Smart Doll Production Jobs

Wise Doll production is carried out in Japan – physique frames are injection molded in Yamagata and outer shell components casted in Katsushika Tokyo. Some apparel and wig items are created in Korea which has a rich BJD (Ball Jointed Doll) culture.
Intelligent Doll production is fascinating since it is our very first time undertaking it. There is so considerably to find out, invent, develop and expand/boost upon.

The BJD is still a little niche market place and it really is our job to bring this kind of art and inspiration to the rest of the planet – and we have been carrying out so – about 80% of our clients are initial time style doll owners.

Inventory, Purchase Order Management and Sales Forecasting
They may all sound boring but managing these three things is essential for any organization.
This job also includes managing relationships with vendors who make elements for us and anyone operating on this group can expect 80% of their time to be devoted to preserving our good quality standards.

Vendor’s are generally great at performing their specialist jobs but the level of high quality is set by their clientele expectations – for this purpose it is usually difficult in educating and changing the culture of vendors to function with our high good quality needs.

Wise Doll Production
The Intelligent Doll production group takes all the components and assembles everything together – but ahead of this is done, parts need to be rechecked (even right after QA has gone by way of them, the flash requirements to be reduce and a load of other processes need to be total just before the physique is ready to be packed.

Apparel Improvement
Although there are several doll seamstresses out there who can make high good quality apparel in small quantities, there are not numerous locations in the planet that are able to mass make miniature garments at high high quality.

In order to speed up the idea &gt marketplace ready process, 1 of my targets is to boost headcount of our apparel team in Tokyo and setup apparel studios in a variety of locations across Japan

Licensing
Sensible Doll is the best platform for character license improvement for anime, games and Hollywood motion pictures too. In the very near future we strategy to start producing Smart Doll’s of numerous characters and will be needing people to handle not only the licensing agreements and supervision of prototypes at every stage by the licence holder, but also handle the production that will be involved in recreating the visual appear and feel of the character in miniature form.

Product Development
Product improvement is also accomplished in our Tokyo offices. Collectively with our own 3D modeling group and 3D printers, we rely heavily on 3D fast prototyping strategies to get our merchandise to industry within brief cycles.

Right after prototype creation, this team then has to work out how and where the item is going to be mass developed, how it will be QC’ed, what the packaging will appear like and how its made and so forth.

This team is also accountable for items like making slush or injection molds, procuring elements and material, generating paint masks for the faceup (painting of the face), improvement of the eyes which entails considering ink saturation and how light is bent through the acrylic depending on the eye radius and distance of print from eye surface and so forth.

Quality Manage
80% of our time is taken up by Top quality Control. All components that arrive in our workplace in Tokyo are checked and exactly where achievable we attempt to repair something that can be done in home – if not we send them back to the vendors and give them a spanking.

Fulfillment &amp Customer Service
At the moment most of our orders are taken online utilizing Shopify and often people come to the workplace to choose up. As we are nonetheless new to all of this, much of this procedure is nevertheless extremely manual and includes printing picking lists, invoices, packing slips and so on.

Up till lately we employed shared e-mail to manage client queries which was a nightmare but now we are utilizing Zendesk which enables us to collaboratively manage buyer queries and maintain our sanity at the exact same time.

Robotics
The Automated version of Wise Doll is now identified as Intelligent Doll Plus. Robotics development is a prohibitively high-priced – we could simply spend all our money flow on its production but thankfully have more sense than money so we focus on the &quotManual&quot version which is already on the industry and creating a self sustainable company for us.

Possessing said that, I do devote resources working on this as a side project and will comprehensive it.

3D Engineering
Our 3D Engineers are equipped with abilities to use a variety of 3D application such as ZBrush, SolidWorks, Autocad, Rhinoceros, 3D Max, Maya etc and are totally versed in issues relating to preparing the data for machining molds or for the printers we use in the office.
Our engineers have a excellent understanding about the numerous types of manufacture and material properties which enables them to design and style although taking into account numerous variables such as injection molding slide, ejector pin, warpage, shrinkage issues and so on.

Long Description:
Whether it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a successful and versatile fighter aircraft for the duration of the very first half of World War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese stay among the most common airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the initial American ace of Globe War II whilst flying a P-40E when he shot down six Japanese aircraft in the course of mid-December 1941. P-40s had been very first-line Army Air Corps fighters at the start off of the war but they quickly gave way to a lot more advanced designs such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for each aircraft). The P-40 is not ranked amongst the very best overall fighters of the war but it was a rugged, successful style obtainable in huge numbers early in the war when America and her allies urgently necessary them. The P-40 remained in production from 1939 to the finish of 1944 and a total of 13, 737 had been constructed.

Design and style engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he designed the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the biggest Army airplane contract awarded since World War I. Worldwide, fighter aircraft styles matured rapidly throughout the late 1930s and it was quickly apparent that the P-36 was no match for newer European styles. Higher altitude efficiency in particular became a priceless commodity. Berlin attempted to boost the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not trustworthy and Berlin had placed the cockpit too far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not providing difficulty, the more-streamlined XP-37 was considerably faster than the P-36.

Curtiss attempted again in 1938. Berlin had modified yet another P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and initial flew on October 14, 1938. The XP-40 looked promising and Curtiss provided it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with several other fighter proposals. The P-40 won the competitors, soon after some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and 4 .30 caliber machine guns in the wings.

Right after production started in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but located they performed poorly in higher-altitude combat over northern Europe and relegated them to low-altitude operations in North Africa. The Russians purchased far more than two,000 P-40s but information of their operational history stay obscure.

When the United States declared war, P-40s equipped numerous of the Army Air Corps’s front line fighter units. The plucky fighter at some point saw combat in nearly every theater of operations becoming the most powerful in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the whole war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized right after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault nearly 9 million dollars in 1940 to get aircraft and recruit pilots to fly against the Japanese. Chennault’s most critical help within the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s general commander.

The funds from China diverted an order placed by the British Royal Air Force for one hundred Curtiss-Wright P-40B Tomahawks but getting airplanes was only 1 essential step in making a fighting air unit. Educated pilots had been necessary, and quickly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit straight from the ranks of American military reserve pilots. Inside a couple of months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps although the Army Air Corps supplied a single-third. Factory test pilots at Bell, Consolidated, and other firms, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their very first mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, large radiator air intake. The idea is mentioned to originate from photographs in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted around their air intakes. The Flying Tigers have been the first true opposition the Japanese military encountered. In less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July 4, 1942, and its assets, like a handful of pilots, became a part of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier General, assumed command of the 14th AF and by war’s finish, the 23rd was one particular of the highest-scoring Army fighter groups.

As wartime experience in the P-40 mounted, Curtiss made many modifications. Engineers added armor plate, far better self-sealing fuel tanks, and a lot more powerful engines. They modified the cockpit to improve visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the first model with this gun package and it entered service in time to serve in the AVG. The final model produced in quantity was the P-40N, the lightest P-40 built in quantity, and considerably more quickly than prior models. Curtiss built a single P-40Q. It was the fastest P-40 to fly (679 kph/422 mph) but it could not match the overall performance of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, a lot of Allied nations purchased and flew P-40s which includes England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright constructed it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to assist defend the region. Soon after the Japanese threat diminished, the unit returned to Canada and sooner or later transferred to England without its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft sooner or later returned to the United States. It had a number of owners just before ending up with the Explorer Scouts youth group in Meridian, Mississippi. For the duration of the early 1960s, the Smithsonian began browsing for a P-40 with a documented history of service in the AVG but discovered none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a neighborhood man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that 1st flew in 1938. It was utilized by the air forces of 28 nations, including these of most Allied powers in the course of Planet War II, and remained in front line service until the end of the war. It was the third most-created American fighter, soon after the P-51 and P-47 by November 1944, when production of the P-40 ceased, 13,738 had been constructed, all at Curtiss-Wright Corporation‘s principal production facility at Buffalo, New York.

The P-40 style was a modification of the previous Curtiss P-36 this lowered improvement time and enabled a rapid entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, making it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces employed the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger made it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in high-altitude combat and it was rarely employed in operations in Northwest Europe. Amongst 1941 and 1944, nonetheless, the P-40 played a crucial role with Allied air forces in 3 main theaters: North Africa, the Southwest Pacific and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s overall performance at higher altitudes was not as critical in these theaters, where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force‘s No. 112 Squadron was among the 1st to operate Tomahawks, in North Africa, and the unit was the first to function the &quotshark mouth&quot logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. [N 1]

Though it gained a post-war reputation as a mediocre design, appropriate only for close air assistance, much more current analysis including scrutiny of the records of person Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at occasions suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 supplied the further benefit of low cost, which kept it in production as a ground-attack fighter extended right after it was obsolete in the air superiority part.

As of 2008, 19 P-40s were airworthy.

Astoria Scum River Bridge

For much more than twenty years, a leaky pipe on 33rd Street beneath the Hell Gate Bridge viaduct approach submerged a lot more than a hundred square feet of heavily-trafficked sidewalk under a festering cesspool of standing water. Astoria Scum River, as it was known as, stretched the whole width of the sidewalk, and as winter approached, the river iced over and became particularly hazardous to cross.

Astoria Scum River Bridge was constructed to provide Astorians an opportunity to safely cross this hazard. The unauthorized bridge was a present to the pedestrians of Astoria in the absence of effective municipal efforts to ameliorate the problem.

The bridge was made at zero price completely from recycled supplies: an old work bench discovered on the curb, rescued screws from a disassembled desk, and a metal plate from an expired electrical element. It was installed and devoted on December 30th, 2009.

On January 25th, 2010, Astoria Scum River Bridge was the subject of a commendation from the workplace of NYC Council Member Peter F. Vallone, Jr., accompanied by a pledge to work with Amtrak to re-route Astoria Scum River off the sidewalk.

Two days later, Amtrak workers began construction operate. Astoria Scum River was speedily routed off the sidewalk, and inside a couple months, custom-made grates have been installed to comprehensive the project. The bridge, no longer required, was de-installed on March 20th, 2010 and returned to the curb whence it came.
