Consolidated B-24 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long Range (aeronautics), range and the ability to carry a heavy Aerial bomb, bomb load. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower Ceiling (aeronautics), ceiling and was less robust than the Boeing B-17 Flying Fortress. While Aircrew#Military, aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. At approximately 18,500 units – including 8,68 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lines Of Communications
A line of communication (or communications) is the route that connects an operating military unit with its supply base. Supplies and reinforcements are transported along the line of communication. Therefore, a secure and open line of communication is vital for any military force to continue to operate effectively. Prior to the advent of the use of the telegraph and radio in warfare, lines of communication were also the routes used by dispatch riders on horseback and runners to convey and deliver orders and battle updates to and from unit commanders and headquarters. Thus, a unit whose lines of communication were compromised was vulnerable to becoming isolated and destroyed, as the means for requesting reinforcements and resupply is lost. The standard military abbreviation is LOC. There is also SLOC for Sea Line of Communication, GLOC for Ground Line of Communication, or ALOC for Air Line of Communication. The interdiction of supplies and reinforcements to units closer to the fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synthetic Oil
Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks. There are various types of synthetic oils. Advantages of using synthetic motor oils include better low-and high-temperature viscosity performance, better (higher) viscosity index (VI), and chemical and shear stability, while disadvantages are that synthetics are substantially more expensive (per volume) than mineral oils and have potential decomposition problems. Description Synthetic oil lubricant comprises chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. The base material, however, is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2d Bombardment Division
D, or d, is the fourth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''dee'' (pronounced ), plural ''dees''. History The Semitic letter Dāleth may have developed from the logogram for a fish or a door.

In Semitic, Ancient Greek and Latin, the letter represented ; in the Etruscan alphabet the letter was archaic but still retained. The equivalent Greek letter is delta, Δ. The minuscule (lower-case) form of 'd' consists of a lower-story left bowl and a stem ascender. It most likely developed by gradual variations on the majuscule (capital) form 'D', and is now composed as a stem with a full lobe to the right. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This serif was extended while the rest of th ...

D-Day
The Normandy landings were the landing operations and associated airborne operations on 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during the Second World War. Codenamed Operation Neptune and often referred to as D-Day (after the military term), it is the largest seaborne invasion in history. The operation began the liberation of France, and the rest of Western Europe, and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on the day selected for D-Day was not ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the planners had requirements for the phase of the moon, the tides, and time of day, that ...
