Latécoère 611
The Latécoère 611 was a French four-engined maritime reconnaissance flying boat of the Second World War. Although only a single prototype was completed, this served throughout the war, being used by both the Vichy French and Free French navies. Development and design In May 1935, the French Navy issued a specification for a long-range flying boat to replace the obsolete Breguet 521. To meet this requirement, Latécoère designed the Latécoère 611. This was a cantilever monoplane powered by four Gnome-Rhone 14N radial engines and fitted with a twin tail. It was also fitted with stabilising floats that retracted into the outer engine nacelles. The prototype was assembled at Biscarrosse, and first flew on 8 March 1939. Although it was intended that the aircraft be armed with a 25 mm cannon in a dorsal turret, this was unavailable, and was replaced by one carrying two 7.5 mm Darne machine guns, with a further four machine guns firing through portholes and two in a retr ...

Achernar
Achernar is the brightest star in the constellation of Eridanus, and the ninth-brightest in the night sky. It has the Bayer designation Alpha Eridani, which is Latinized from α Eridani and abbreviated Alpha Eri or α Eri. The name Achernar applies to the primary component of a binary system. The two components are designated Alpha Eridani A (the primary) and B (the secondary), with the latter known informally as Achernar B. As determined by the ''Hipparcos'' astrometry satellite, this system is located at a distance of approximately from the Sun. Of the ten apparent brightest stars in the night-time sky, Alpha Eridani is the hottest and bluest in color, due to Achernar being of spectral type B. Achernar has an unusually rapid rotational velocity, causing it to become oblate in shape. The secondary is smaller, of spectral type A, and orbits Achernar at a distance of . Nomenclature ''α Eridani'' ( Latinised to ''Alpha Eridani'') is the system's Bayer designation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 Mm Hotchkiss Anti-aircraft Gun
The Hotchkiss 25 mm anti-aircraft gun was an anti-aircraft autocannon designed by the French firm of Hotchkiss. It served in World War II with French, Japanese and other nations' forces. Other than the designer company and the calibre, this weapon is not related to the semi-automatic 25 mm Hotchkiss anti-tank gun; in particular, the cartridge used is different. Development After World War I the French military expressed a need for an anti-aircraft autocannon. The Hotchkiss company submitted its 25 mm design, but it was rejected as being too slow-firing, so the weapon was proposed for export instead. In 1938, as the international situation was worsening, and the favoured Schneider 37 mm autocannon was still not ready for production, the French military decided to reconsider its refusal to Hotchkiss, who had just won a contract with Romania. The export guns were held in France and impressed into domestic service. The original tripod was found to be unstable, which l ...

Gnome-Rhône 14N
The Gnome-Rhône 14N was a 14-cylinder two-row air-cooled radial engine designed and manufactured by Gnome-Rhône just before the start of World War II. A development of the Gnome-Rhône 14K, the 14N was used on several French and even one German aircraft. Design and development The 14K's reliability was poor, so Gnome-Rhône carried out major redesign, using different materials for the pistons and valves, and enlarging the cooling fins to increase surface area by 39%. The 14N was introduced in 1937 and was quickly installed on several aircraft models. In 1939, minor improvements allowed Gnome-Rhône to increase the compression ratio from 6.1:1 to 6.8:1, which increased power. The 14N was further developed into the Gnome-Rhône 14R featuring a 2-stage supercharger, but this type was not widely used until after World War II as production of improved engines was restricted by the armistice with Germany.

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Sunderland
The Short S.25 Sunderland is a British flying boat patrol bomber, developed and constructed by Short Brothers for the Royal Air Force (RAF). The aircraft took its service name from the town (latterly, city) and port of Sunderland in North East England. Developed in parallel with the civilian Short Empire, S.23 ''Empire'' flying boat, the flagship of Imperial Airways, the Sunderland was developed specifically to conform to the requirements of British Air Ministry List of Air Ministry specifications#1930.E2.80.931939, Specification R.2/33 for a long-range patrol/reconnaissance flying boat to serve with the Royal Air Force (RAF). As designed, it served as a successor to the earlier Short Sarafand flying boat. Sharing several similarities with the S.23, it featured a more advanced aerodynamic hull and was outfitted with various offensive and defensive armaments, including machine gun Gun turret#Aircraft, turrets, bombs, Parachute mine, aerial mines, and depth charges.

South Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Operation Torch
Operation Torch (8 November 1942 – Run for Tunis, 16 November 1942) was an Allies of World War II, Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to engage in the fight against Nazi Germany on a limited scale. It was the first mass involvement of US troops in the Mediterranean and Middle East theatre of World War II, European–North African Theatre, and saw the first major airborne assault carried out by the United States. While the French colonies were formally aligned with Germany via Vichy France, the loyalties of the population were mixed. Reports indicated that they might support the Allies. American General Dwight D. Eisenhower, supreme commander of the Allied forces in Mediterranean Theater of Operations, planned a three-pronged attack on Casablanca (Western), Oran (Center) and Algiers (Easter ...
