55-606: Unveiled by the U.S. Air Force on 30 April 1996, the Tacit Blue Technology Demonstration Program was designed to prove that such an aircraft could continuously monitor the ground situation deep behind the battlefield and provide targeting information in real time to a ground command center . In December 1976, DARPA and the U.S. Air Force initiated the Battlefield Surveillance Aircraft-Experimental (BSAX) program, which

110-471: A dramatic intensification of the pace of social changes, and was a crucial catalyst for the growth of left-wing politics . Mao Zedong urged the socialist camp not to fear nuclear war with the United States since, even if "half of mankind died, the other half would remain while imperialism would be razed to the ground and the whole world would become socialist." A distinctive feature of war since 1945

165-502: A few years. While conventional wisdom holds that casualties have increased in recent times due to technological improvements in warfare, this is not generally true. For instance, the Thirty Years' War (1618–1648) had about the same number of casualties per capita as World War I , although it was higher during World War II (WWII). That said, overall the number of casualties from war has not significantly increased in recent times. Quite to

220-434: A finding supported by other researchers. Keeley explains that early war raids were not well organized, as the participants did not have any formal training. Scarcity of resources meant defensive works were not a cost-effective way to protect the society against enemy raids. William Rubinstein wrote "Pre-literate societies, even those organized in a relatively advanced way, were renowned for their studied cruelty.'" Since

275-508: A general feature of animal social behavior. Some proponents of the idea argue that war, while innate, has been intensified greatly by developments of technology and social organization such as weaponry and states. Psychologist and linguist Steven Pinker argued that war-related behaviors may have been naturally selected in the ancestral environment due to the benefits of victory. He also argued that in order to have credible deterrence against other groups (as well as on an individual level), it

330-514: A given operational area and timeframe, and normally supports the joint force's future plans effort, which is overseen by the plans directorate of a joint staff (J-5). (Normally, the future operations directorate focuses on 24 hours up to 72 hours. This is a critical linkage during targeting execution.) By contrast, dynamic targeting prosecutes targets that were not included in the deliberate targeting process, possibly because they were not known or not initially selected for prosecution. Dynamic targeting

385-469: A noble cause is a contributing factor towards war, few wars have originated from a desire for war among the general populace. Far more often the general population has been reluctantly drawn into war by its rulers. One psychological theory that looks at the leaders is advanced by Maurice Walsh. He argues the general populace is more neutral towards war and wars occur when leaders with a psychologically abnormal disregard for human life are placed into power. War

440-602: A source of violent conflict. Pope Urban II in 1095, on the eve of the First Crusade , advocating Crusade as a solution to European overpopulation, said: For this land which you now inhabit, shut in on all sides by the sea and the mountain peaks, is too narrow for your large population; it scarcely furnishes food enough for its cultivators. Hence it is that you murder and devour one another, that you wage wars, and that many among you perish in civil strife. Let hatred, therefore, depart from among you; let your quarrels end. Enter upon

495-423: A three-year period. The aircraft often flew three to four flights weekly and several times flew more than once a day. Another Tacit Blue test pilot, Ken Dyson, told CNN in 2014 that Northrop had manufactured additional major components for the jet, which amounted to half of a second plane. "If we lost one, we could have a second one up and flying in short order," Dyson said. After reaching about 250 flight hours,

550-560: A war". Tangible/intangible aims: Explicit/implicit aims: Positive/negative aims: War aims can change in the course of conflict and may eventually morph into "peace conditions" – the minimal conditions under which a state may cease to wage a particular war. Throughout the course of human history, the average number of people dying from war has fluctuated relatively little, being about 1 to 10 people dying per 100,000. However, major wars over shorter periods have resulted in much higher casualty rates, with 100–200 casualties per 100,000 over

605-732: Is a Mesolithic cemetery in Jebel Sahaba , which has been determined to be about 13,400 years old. About forty-five percent of the skeletons there displayed signs of violent death, specifically traumatic bone lesions. In War Before Civilization , Lawrence H. Keeley , a professor at the University of Illinois , says approximately 90–95% of known societies throughout history engaged in at least occasional warfare, and many fought constantly. Keeley describes several styles of primitive combat such as small raids , large raids, and massacres . All of these forms of warfare were used by primitive societies,

660-491: Is a six phase iterative process: Phase 1 - End state and commander's objectives, Phase 2 - Target development and prioritization, Phase 3 - Capabilities analysis, Phase 4 - Commander's decision and force assignment, Phase 5 - Mission planning and force execution, Phase 6 - Assessment. General Stanley A. McChrystal wrote in 2014 about a targeting cycle called "F3EA" used in the Iraq War , which stands for: Warfare War

715-404: Is an armed conflict between the armed forces of states , or between governmental forces and armed groups that are organized under a certain command structure and have the capacity to sustain military operations, or between such organized groups. It is generally characterized by extreme violence , destruction, and mortality, using regular or irregular military forces . Warfare refers to

770-613: Is caused by leaders who seek war such as Napoleon and Hitler . Such leaders most often come to power in times of crisis when the populace opts for a decisive leader, who then leads the nation to war. Naturally, the common people don't want war; neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine

825-493: Is commonplace encourage their children to be more aggressive. War can be seen as a growth of economic competition in a competitive international system. In this view wars begin as a pursuit of markets for natural resources and for wealth. War has also been linked to economic development by economic historians and development economists studying state-building and fiscal capacity . While this theory has been applied to many conflicts, such counter arguments become less valid as

880-608: Is estimated that between 1985 and 1994, 378,000 people per year died due to war. Most wars have resulted in significant loss of life, along with destruction of infrastructure and resources (which may lead to famine , disease, and death in the civilian population ). During the Thirty Years' War in Europe, the population of the Holy Roman Empire was reduced by 15 to 40 percent. Civilians in war zones may also be subject to war atrocities such as genocide , while survivors may suffer

935-547: Is fueled by displacement and projection where a person transfers his or her grievances into bias and hatred against other races , religions , nations or ideologies . By this theory, the nation state preserves order in the local society while creating an outlet for aggression through warfare. The Italian psychoanalyst Franco Fornari , a follower of Melanie Klein , thought war was the paranoid or projective "elaboration" of mourning. Fornari thought war and violence develop out of our "love need": our wish to preserve and defend

990-407: Is normally employed in current operations planning because the nature and time frame associated with current operations (usually the current 24-hour period) typically requires more immediate responsiveness compared to deliberate targeting. Technologically advanced countries can generally select their targets in such a way as to minimize collateral damage and civilian casualties . This can fall by

1045-512: Is on identifying resources (targets) the enemy can least afford to lose or that provide him with the greatest advantage (high-value target [HVT]), then further identifying the subset of those targets that must be acquired and engaged to achieve friendly success (high-payoff target [HPT]). Targeting links the desired effects to actions and tasks. The targeting process can be generally grouped into two categories: deliberate and dynamic. Deliberate targeting prosecutes anticipated or known targets within

1100-816: Is that combat has largely been a matter of civil wars and insurgencies. The major exceptions were the Korean War , the Indo-Pakistani War of 1971 , the Iran–Iraq War , the Gulf War , the Eritrean–Ethiopian War , and the Russo-Ukrainian War . The Human Security Report 2005 documented a significant decline in the number and severity of armed conflicts since the end of the Cold War in the early 1990s. However,

1155-448: Is the process of selecting objects or installations to be attacked, taken, or destroyed in warfare . Targeting systematically analyzes and prioritizes targets and matches appropriate lethal and nonlethal actions to those targets to create specific desired effects that achieve the joint force commander's (JFC's) objectives, accounting for operational requirements, capabilities, and the results of previous assessments. The emphasis of targeting

1210-866: The American Civil War , including about 6% in the North and approximately 18% in the South. The war remains the deadliest conflict in American history, resulting in the deaths of 620,000 military personnel. United States military casualties of war since 1775 have totaled over two million. Of the 60 million European military personnel who were mobilized in World War I , 8 million were killed, 7 million were permanently disabled, and 15 million were seriously injured. During Napoleon 's retreat from Moscow, more French military personnel died of typhus than were killed by

1265-582: The B-2 bomber . A single flush inlet on the top of the fuselage provided air to two medium-bypass turbofan engines. Tacit Blue employed a quadruply redundant digital fly-by-wire flight control system to help stabilize the aircraft about its longitudinal and directional axes. The aircraft made its first successful flight on February 5, 1982, in Area 51 , at Groom Lake, Nevada , flown by Northrop test pilot Richard G. Thomas . The aircraft subsequently logged 135 flights over

1320-483: The Soviet Union were around 27   million . Since a high proportion of those killed were young men who had not yet fathered any children, population growth in the postwar Soviet Union was much lower than it otherwise would have been. Once a war has ended, losing nations are sometimes required to pay war reparations to the victorious nations. In certain cases, land is ceded to the victorious nations. For example,

1375-661: The 11th-century Old English words wyrre and werre , from Old French werre (also guerre as in modern French), in turn from the Frankish * werra , ultimately deriving from the Proto-Germanic * werzō ' mixture, confusion ' . The word is related to the Old Saxon werran , Old High German werran , and the modern German verwirren , meaning ' to confuse, to perplex, to bring into confusion ' . The earliest evidence of prehistoric warfare

1430-680: The Great Depression, though some consider that it did not play a very large role in the recovery, though it did help in reducing unemployment. In most cases, such as the wars of Louis XIV, the Franco-Prussian War , and World War I , warfare primarily results in damage to the economy of the countries involved. For example, Russia's involvement in World War I took such a toll on the Russian economy that it almost collapsed and greatly contributed to

1485-554: The Neanderthals and ancestors of apes and primates. For the period 3000 BCE until 1991, estimates range from 151   million to 2   billion. The deadliest war in history, in terms of the cumulative number of deaths since its start, is World War II , from 1939 to 1945, with 70–85 million deaths, followed by the Mongol conquests at up to 60 million. As concerns a belligerent's losses in proportion to its prewar population,

1540-684: The Russians. Of the 450,000 soldiers who crossed the Neman on 25 June 1812, less than 40,000 returned. More military personnel were killed from 1500 to 1914 by typhus than from military action. In addition, if it were not for modern medical advances there would be thousands more dead from disease and infection. For instance, during the Seven Years' War , the Royal Navy reported it conscripted 184,899 sailors, of whom 133,708 (72%) died of disease or were 'missing'. It

1595-438: The United States and U.S. Generals , expressed support for an economic view of war. The Marxist theory of war is quasi-economic in that it states all modern wars are caused by competition for resources and markets between great ( imperialist ) powers, claiming these wars are a natural result of capitalism . Marxist economists Karl Kautsky , Rosa Luxemburg , Rudolf Hilferding and Vladimir Lenin theorized that imperialism

1650-400: The adversary. Every target has distinct intrinsic or acquired characteristics that form the basis for target detection, location, identification, and classification for ongoing and future surveillance, analysis, engagement, and assessment. Physical, functional, cognitive, environmental, and temporal are broad categories that help define the characteristics of a target. The joint targeting cycle

1705-749: The aircraft was placed in storage in 1985. In 1996, after Tacit Blue was declassified, it was placed on display at the National Museum of the United States Air Force at Wright-Patterson Air Force Base , near Dayton, Ohio and has been on display in the fourth hangar at the museum since June 2016.

1760-988: The chances of becoming a psychiatric casualty – of being debilitated for some period of time as a consequence of the stresses of military life – were greater than the chances of being killed by enemy fire. Swank and Marchand's World War II study found that after sixty days of continuous combat, 98% of all surviving military personnel will become psychiatric casualties. Psychiatric casualties manifest themselves in fatigue cases, confusional states, conversion hysteria, anxiety, obsessional and compulsive states, and character disorders. One-tenth of mobilised American men were hospitalised for mental disturbances between 1942 and 1945, and after thirty-five days of uninterrupted combat, 98% of them manifested psychiatric disturbances in varying degrees. Additionally, it has been estimated anywhere from 18% to 54% of Vietnam war veterans suffered from posttraumatic stress disorder . Based on 1860 census figures, 8% of all white American males aged 13 to 43 died in

1815-495: The common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate military targets , and can result in massive civilian or other non-combatant suffering and casualties . While some war studies scholars consider war a universal and ancestral aspect of human nature , others argue it is a result of specific socio-cultural, economic, or ecological circumstances. The English word war derives from

1870-420: The concept of massed standoff attacks on advancing armored formations using smart munitions . The Pave Mover radar demonstrators provided the non-stealth portion of the program's targeting system , whereas Tacit Blue was intended to demonstrate a similar but stealth capability, while validating a number of innovative stealth technology advances. The radar sensor technology developed for Tacit Blue evolved into

1925-768: The conflict, and increased revenues by weapons manufacturers . Three of the ten most costly wars, in terms of loss of life, have been waged in the last century. These are the two World Wars, followed by the Second Sino-Japanese War (which is sometimes considered part of World War II , or as overlapping). Most of the others involved China or neighboring peoples. The death toll of World War II, being over 60 million, surpasses all other war-death-tolls. Military personnel subject to combat in war often suffer mental and physical injuries, including depression, posttraumatic stress disorder , disease, injury, and death. In every war in which American soldiers have fought in,

1980-414: The contrary, on a global scale the time since WWII has been unusually peaceful. Estimates for total deaths due to war vary widely. In one estimate, primitive warfare from 50,000 to 3000 BCE has been thought to have claimed 400   million±133,000 victims based on the assumption that it accounted for the 15.1% of all deaths. Other scholars find the prehistoric percentage much lower, around 2%, similar to

2035-584: The evidence examined in the 2008 edition of the Center for International Development and Conflict Management's "Peace and Conflict" study indicated the overall decline in conflicts had stalled. Entities contemplating going to war and entities considering whether to end a war may formulate war aims as an evaluation/propaganda tool. War aims may stand as a proxy for national-military resolve. Fried defines war aims as "the desired territorial, economic, military or other benefits expected following successful conclusion of

2090-459: The increasing mobility of capital and information level the distributions of wealth worldwide, or when considering that it is relative, not absolute, wealth differences that may fuel wars. There are those on the extreme right of the political spectrum who provide support, fascists in particular, by asserting a natural right of a strong nation to whatever the weak cannot hold by force. Some centrist, capitalist, world leaders, including Presidents of

2145-498: The most destructive war in modern history may have been the Paraguayan War (see Paraguayan War casualties ). In 2013 war resulted in 31,000 deaths, down from 72,000 deaths in 1990. War usually results in significant deterioration of infrastructure and the ecosystem, a decrease in social spending, famine , large-scale emigration from the war zone, and often the mistreatment of prisoners of war or civilians. For instance, of

2200-542: The motivations for war, but no consensus about which are most common. Military theorist Carl von Clausewitz said, "Every age has its own kind of war, its own limiting conditions, and its own peculiar preconceptions." Dutch psychoanalyst Joost Meerloo held that, "War is often...a mass discharge of accumulated internal rage (where)...the inner fears of mankind are discharged in mass destruction." Other psychoanalysts such as E.F.M. Durban and John Bowlby have argued human beings are inherently violent. This aggressiveness

2255-590: The nature and presence of warfare. Thus, he argues, warfare is not a universal human occurrence and appears to have been a historical invention, associated with certain types of human societies. Montagu's argument is supported by ethnographic research conducted in societies where the concept of aggression seems to be entirely absent, e.g. the Chewong and Semai of the Malay peninsula. Bobbi S. Low has observed correlation between warfare and education, noting societies where warfare

2310-516: The nine million people who were on the territory of the Byelorussian SSR in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians). Another byproduct of some wars is the prevalence of propaganda by some or all parties in

2365-399: The policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship. ... the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works

2420-525: The psychological aftereffects of witnessing the destruction of war. War also results in lower quality of life and worse health outcomes. A medium-sized conflict with about 2,500 battle deaths reduces civilian life expectancy by one year and increases infant mortality by 10% and malnutrition by 3.3%. Additionally, about 1.8% of the population loses access to drinking water . Most estimates of World War II casualties indicate around 60 million people died, 40 million of whom were civilians. Deaths in

2475-634: The radar now being used by the E-8 Joint STARS aircraft. Tacit Blue was given the cover designation of "YF-117D" by the Air Force. Tacit Blue, nicknamed "the whale" (and sometimes also called an "alien school bus" for its only slightly rounded-off rectangular shape), featured a straight tapered wing with a V-tail mounted on an oversized fuselage with a curved shape. It was the first stealth aircraft to feature curved surfaces for radar cross-section reduction. Northrop would use this stealth technology on

2530-419: The rise of the state some 5,000 years ago, military activity has continued over much of the globe. The invention of gunpowder , and its eventual use in warfare, together with the acceleration of technological advances have fomented major changes to war itself. In Western Europe, since the late 18th century, more than 150 conflicts and about 600 battles have taken place. During the 20th century, war resulted in

2585-407: The sacred object to which we are attached, namely our early mother and our fusion with her. For the adult, nations are the sacred objects that generate warfare. Fornari focused upon sacrifice as the essence of war: the astonishing willingness of human beings to die for their country, to give over their bodies to their nation. Despite Fornari's theory that man's altruistic desire for self-sacrifice for

2640-668: The same way in any country. Several theories concern the evolutionary origins of warfare. There are two main schools: One sees organized warfare as emerging in or after the Mesolithic as a result of complex social organization and greater population density and competition over resources; the other sees human warfare as a more ancient practice derived from common animal tendencies, such as territoriality and sexual competition. The latter school argues that since warlike behavior patterns are found in many primate species such as chimpanzees , as well as in many ant species, group conflict may be

2695-461: The start of the Russian Revolution of 1917 . World War II was the most financially costly conflict in history; its belligerents cumulatively spent about a trillion U.S. dollars on the war effort (as adjusted to 1940 prices). The Great Depression of the 1930s ended as nations increased their production of war materials. By the end of the war, 70% of European industrial infrastructure

2750-506: The territory of Alsace-Lorraine has been traded between France and Germany on three different occasions. Typically, war becomes intertwined with the economy and many wars are partially or entirely based on economic reasons. The common view among economic historians is that the Great Depression ended with the advent of World War II . Many economists believe that government spending on the war caused or at least accelerated recovery from

2805-414: The wayside, however, during unrestricted warfare. Targeting may also refer to the targeting of the actual objective to be destroyed by military personnel, such as "painting" a target with a laser for laser guided munitions, estimating range for artillery , etc. A target is an entity (person, place, or thing) considered for possible engagement or action to alter or neutralize the function it performs for

2860-578: Was destroyed. Property damage in the Soviet Union inflicted by the Axis invasion was estimated at a value of 679 billion rubles. The combined damage consisted of complete or partial destruction of 1,710 cities and towns, 70,000 villages/hamlets, 2,508 church buildings, 31,850 industrial establishments, 40,000 mi (64,374 km) of railroad, 4100 railroad stations, 40,000 hospitals, 84,000 schools, and 43,000 public libraries. There are many theories about

2915-667: Was important to have a reputation for retaliation, causing humans to develop instincts for revenge as well as for protecting a group's (or an individual's) reputation (" honor "). Crofoot and Wrangham have argued that warfare, if defined as group interactions in which "coalitions attempt to aggressively dominate or kill members of other groups", is a characteristic of most human societies. Those in which it has been lacking "tend to be societies that were politically dominated by their neighbors". Ashley Montagu strongly denied universalistic instinctual arguments, arguing that social factors and childhood socialization are important in determining

2970-424: Was part of a larger Air Force program called Pave Mover . The BSAX program's goal was to develop an efficient stealth reconnaissance aircraft with a low probability of intercept radar and other sensors that could operate close to the forward line of battle with a high degree of survivability . Tacit Blue represented the " black " component in the larger " Assault Breaker " program, which intended to validate

3025-533: Was the result of capitalist countries needing new markets . Expansion of the means of production is only possible if there is a corresponding growth in consumer demand . Since the workers in a capitalist economy would be unable to fill the demand, producers must expand into non-capitalist markets to find consumers for their goods, hence driving imperialism. Demographic theories can be grouped into two classes, Malthusian and youth bulge theories: Malthusian theories see expanding population and scarce resources as
