Horten Ho 229

The Horten H.IXRLM designation Ho 229 (often called Gotha Go 229 due to the identity of the chosen manufacturer of the aircraft) was a late-World War II prototypefighter/bomber designed by Reimar and Walter Horten and built by Gothaer Waggonfabrik. It was the first pure flying wing powered by a jet engine. and designed to be more difficult to detect with radar - the first aircraft to incorporate what is now known as stealth technology.It was a personal favorite of German Luftwaffechief Reichsmarschall Hermann Göring, and was the only aircraft to come close to meeting his "1000, 1000, 1000" performance requirements. Its speed was estimated at 1,024 km/h (636 mph) and its ceiling 15,000 meters (49,213 ft)

Kawanishi H8K

The Kawanishi H8K (二式大型飛行艇, Type 2 Large Flying Boat. 二式大艇, Nishiki DaiteiNishiki Taitei) was an Imperial Japanese Navy flying boat used during World War II for maritime patrol duties. The Allied reporting name for the type was "Emily".At the same time the type's predecessor, the Kawanishi H6K, was going into service in 1938 the Navy ordered the development of a larger, longer-ranged patrol aircraft under the designation Navy Experimental 13-Shi Large-size Flying Boat.The result was a large, shoulder-winged design that is widely regarded as the best flying boat of the war.Despite this, initial development was troublesome, with the prototype displaying terrible handling on the water. Deepening of the hull, redesigning of the planing bottom and the addition of spray strips under the nose rectified this.Two further prototypes -actually pre-production aircraft- joined the development program in December 1941.
The IJNAF accepted the first production version as the H8K1, Navy Type 2 Flying Boat, Model 11, of which 14 would be built.
The improved H8K2 variant soon appeared, and its extremely heavy defensive armament earned it deep respect among Allied aircrews.The H8K2 was an upgrade over the H8K1, having more powerful engines, slightly revised armament, and an increase in fuel capacity. This was to be the definitive variant, with 112 produced.

Curtiss P-40 Warhawk


The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metalfighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. By November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facility at Buffalo, New York.
The P-40 design was a modification of the previous Curtiss P-36; this reduced development 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 used 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 used in operations in Northwest Europe. Between 1941 and 1944, however, the P-40 played a critical role with Allied air forces in three major theaters:North Africa, the Southwest Pacific and China. It also had a significant role in theMiddle EastSoutheast AsiaEastern EuropeAlaska and Italy. The P-40's high altitude performance was not as critical in those theaters, where it served as an air supremacy 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 first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo,copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters.
In theatres where high altitude performance was less important, the P-40 proved an effective fighter. Although it gained a post-war reputation as a mediocre design, suitable only for close air support, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground attack fighter long after it was obsolete in air superiority.

P-39 Airacobra

The Bell P-39 Airacobra was one of the principal American fighter aircraft in service at the start of World War II. It was the first fighter in history with a tricycle undercarriage and the first to have the engine installed in the center fuselage, behind the pilot. Although its mid-engine placement was innovative, the P-39 design was handicapped by the lack of an efficient turbo-supercharger, limiting it to low-altitude work. The P-39 was used with great success by the Soviet Air Force, who scored the highest number of individual kills attributed to any U.S. fighter type.Other important users were the Free French and co-belligerent Italian air forces. Together with the derivative P-63 Kingcobra, these aircraft became the most successful mass-produced fixed-wing aircraft manufactured by Bell.

KAMIKAZE

 The Kamikaze (神風?, common translation: "divine wind") ( [kamikaꜜze] (help·info)) Tokubetsu Kougekitai (特別攻撃隊?) Tokkō Tai (特攻隊?) Tokkō (特攻?) were suicide attacks by military aviators from the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, designed to destroy as many warships as possible.

Kamikaze pilots would intentionally attempt to crash their aircraft into enemy ships—planes often laden with explosives, bombs, torpedoes and full fuel tanks. The aircraft's normal functions (to deliver torpedoes or bombs or shoot down other aircraft) were put aside, and the planes were converted to what were essentially manned missiles in an attempt to reap the benefits of greatly increased accuracy and payload over that of normal bombs. The goal of crippling as many Allied ships as possible, particularly aircraft carriers, was considered critical enough to warrant the combined sacrifice of pilots and aircraft.

Prior to the formation of kamikaze units, deliberate crashes had been used as a last effort when a pilot’s plane was severely damaged and he did not want to risk being captured; this was the case in both the Japanese and Allied air forces. According to Axell & Kase, these suicides "were individual, impromptu decisions by men who were mentally prepared to die." In most cases, there is little evidence that these hits were more than accidental collisions, of the kind that sometimes happen in intense sea-air battles. One example of this occurred on December 7, 1941 during the attack on Pearl Harbor. First Lieutenant Fusata Iida’s plane had been hit and was leaking fuel, when he apparently used it to make a suicide attack on Kaneohe Naval Air Station. Before taking off, he had told his men that if his plane was badly damaged he would crash it into a "worthy enemy target".

B-17 Flying Fortress

The Boeing B-17 Flying Fortress was a four-engine heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry outperformed both competitors and more than met the Air Corps' expectations. Although Boeing lost the contract because the prototype crashed, the Air Corps was so impressed with Boeing's design that they ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances.

The B-17 was primarily employed by the United States Army Air Forces (USAAF) in the daylight precision strategic bombing campaign of World War II against German industrial and military targets. The United States Eighth Air Force based at Thorpe Abbotts airfield in England and the Fifteenth Air Force based in Italy complemented the RAF Bomber Command's nighttime area bombing in Operation Pointblank to help secure air superiority over the cities, factories and battlefields of Western Europe in preparation for Operation Overlord. The B-17 also participated to a lesser extent in the War in the Pacific where it conducted raids against Japanese shipping and airfields.

From its pre-war inception, the USAAC (later USAAF) touted the aircraft as a strategic weapon; it was a potent, high-flying, long-range bomber that was able to defend itself, and to return home despite extensive battle damage. It quickly took on mythic proportions, and widely circulated stories and photos of B-17s surviving battle damage increased its iconic status. With a service ceiling greater than any of its Allied contemporaries, the B-17 established itself as an effective weapons system, dropping more bombs than any other U.S. aircraft in World War II. Of the 1.5 million metric tons of bombs dropped on Germany by U.S. aircraft, 640,000 tons were dropped from B-17s.

AICHI D3A VAL

The Aichi D3A (愛知99式艦上爆撃機 Aichi-kyuu-kyuu-shiki-kanjou-bakugeki-ki?), Allied code name "Val") was a World War II dive bomber produced by the Aichi company in Japan. It was the primary carrier-borne dive bomber in the Imperial Japanese Navy in the early stages of the war, and participated in almost all actions, including Pearl Harbor. The Aichi D3A was the first Japanese aircraft to bomb American targets in World War II. Before the war was over, it had sunk more Allied military ships than any other.
