Space warfare in science fiction

Weapons Usually, lasers and other directed-energy weapons are used rather than bullets. Science writer and spaceflight popularizer Willy Ley claimed in 1939 that bullets would be a more effective weapon in a real space battle. Other weapons include torpedoes and other ordnance that is described as employing particles or radiation known to current sub-atomic physics, such as the proton torpedo and photon torpedo from the Star Wars and Star Trek universes, respectively. Conversely, weapons in science fiction often employ fictional materials and kinds of radiation. Often, the radiation or material is specific to the fictional universe in question. For example, the space warships in the Stargate television series do battle with directed-energy weapons that are described as being powered by a fictional metal, called naquadah. '' (1959) Destruction of planets and stars Destruction of planets and stars has been a frequently used aspect of interstellar warfare since the Lensman series. It has been calculated that a force on the order of 1032 joules of energy, or roughly the total output of the sun in a week, would be required to overcome the gravity that holds together an Earth-sized planet. The destruction of Alderaan in Star Wars: Episode IV – A New Hope is estimated to require 1.0 × 1038 joules of energy, millions of times more than would be necessary to break the planet apart at a slower rate. Naval influences Fictional space warfare tends to borrow elements from naval warfare, often calling space forces as space navies or simply navies. David Weber's Honorverse series of novels portrays several of such space navies such as the Royal Manticoran Navy, which imitate themes from Napoleonic-era naval warfare. The Federation Starfleet (Star Trek), Imperial Navy (Star Wars), Systems Alliance Navy (Mass Effect), UNSC (Halo) and Earthforce (Babylon 5) also use a naval-style rank-structure and hierarchy. The former is based on the United States Navy and the Royal Navy. The United Nations Space Command in Halo fully echoes all ranks of the United States Armed Forces, even the pay-grade system. Some fictional universes have different implementations. The Colonial Fleet in Battlestar Galactica uses a mixture of army and navy ranks, and the Stargate universe has military spacecraft under the control of modern air forces, and uses air-force ranks. In the Halo universe, many of the ranks of the current-day United States Armed Forces are used in lieu of fictional ranks. In the Andromeda universe, officers of Systems Commonwealth ships follow naval ranking, but Lancers (soldiers analogous to Marines) use army ranks. Ship types Though the details do differ between various science fiction intellectual properties (IPs for short), classes of ships are most commonly based on those of World War II. Battleships, dreadnoughts and battlecruisers are generally among the largest types of ships, though the three terms are often used interchangeably. Dedicated carriers are rare in science fiction, though not non-existent, featuring prominently in few IPs, such as Wing Commander. Instead, battlecarriers, ships which combine elements of battleships and carriers, are very common, with prominent examples including the Star Destroyer from Star Wars and the titular starship from Battlestar Galactica. Cruisers also make appearances, with some IPs featuring them as the largest and most powerful ships. Prominent example is the Starship Enterprise from Star Trek, occasionally referred to as a heavy cruiser. Destroyers and frigates are often seen as among the smaller ships of the fleet, though in many IPs, both classifications are not used. Corvettes are often the smallest ships in science fiction navies, though some do feature even smaller fast attack craft. Many science-fiction series prominently feature starfighters operating together with larger ships. Prominent examples include the X-wing from Star Wars, the Colonial Viper from Battlestar Galactica and the Starfury from Babylon 5. While most fighters, like the aforementioned ones, tend to be multirole fighters, more specialized fighters do exist as well. The term interceptor, which in reality refers to fast fighters optimized to attack approaching long range heavy bombers, is instead primarily used to refer to fighters designed first and foremost to attack other fighters, generally at the expense of a capability to attack larger warships. Bombers are the opposite of interceptors and are primarily meant to attack enemy warships. Some IPs also feature super-battleship vessels, which are massive warships several kilometers in length, dwarfing even battleships. ==Development of the genre==

In his second-century satire True History, Lucian of Samosata depicts an imperial war between the king of the Sun and the king of the Moon over the right to colonise the Morning Star. It is the earliest known work of fiction to address the concept. The first "future war" story was George T. Chesney's "The Battle of Dorking", a story about a British defeat after a German invasion of Britain, published in 1871 in ''Blackwood's Magazine''. Many such stories were written prior to the outbreak of World War I. George Griffith's The Angel of the Revolution (1893) featured self-styled "Terrorists" armed with then-nonexistent arms and armour such as airships, submarines, and high explosives. The inclusion of yet-nonexistent technology became a standard part of the genre. Griffith's last "future war" story was The Lord of Labour, written in 1906 and published in 1911, which included such technology as disintegrator rays and missiles. H. G. Wells' novel The War of the Worlds inspired many other writers to write stories of alien incursions and wars between Earth and other planets, and encouraged writers of "future war" fiction to employ wider settings than had been available for "naturalistic" fiction. Wells' several other "future war" stories included the atomic war novel The World Set Free (1914) More recent depictions of space warfare departed from the jingoism of the pulp science fiction of the 1930s and 1940s. Joe Haldeman's The Forever War, was partly a response to or a rebuttal of Robert A. Heinlein's Starship Troopers, wherein space warfare involved the effects of time dilation and resulted in the alienation of the protagonists from the human civilization on whose behalf they were fighting. Both novels have in the past been required reading at the United States Military Academy. Science fiction writers from the end of World War II onwards have examined the morality and consequences of space warfare. With Heinlein's Starship Troopers are A. E. van Vogt's "War against the Rull" (1959) and Fredric Brown's "Arena" (1944). Opposing them are Murray Leinster's "First Contact" (1945), Barry Longyear's "Enemy Mine", Kim Stanley Robinson's "The Lucky Strike", Connie Willis' "Schwarzchild Radius", and John Kessel's "Invaders". ==Definitions by contrast==

Space opera The modern form of space warfare in science fiction, in which mobile spaceships battle both planets and one another with destructive superweapons, appeared with the advent of space opera. Garrett P. Serviss' 1898 newspaper serial "Edison's Conquest of Mars" was inspired by Wells and intended as a sequel to "Fighters from Mars", an un-authorized and heavily altered Edisonade version of The War of the Worlds in which the human race, led by Thomas Edison, pursues the invading Martians back to their home planet. David Pringle considers Serviss' story to be the first space opera, although the work most widely regarded as the first space opera is E. E. "Doc" Smith's The Skylark of Space. It and its three successor novels exemplify the present form of space warfare in science fiction, as giant spaceships employ great ray guns that send bolts of energy across space to shatter planets in a war between humans and alien species. David Weber's Honorverse novels present a view of space warfare that simply transplants the naval warfare of Horatio Nelson and Horatio Hornblower into space. The space navy battle tactics in the Honorverse are much like those of Nelson, with the simple addition of a third dimension. Military science fiction Several subsets of military science fiction overlap with space opera, concentrating on large-scale space battles with futuristic weapons. At one extreme, the genre is used to speculate about future wars involving space travel, or the effects of such a war on humans; at the other, it consists of the use of military fiction plots with some superficial science-fiction trappings. The term "military space opera" is occasionally used to denote this subgenre, as used for example by critic Sylvia Kelso when describing Lois McMaster Bujold's Vorkosigan Saga. Other examples of military space opera are the Battlestar Galactica franchise and Robert A. Heinlein's 1959 novel Starship Troopers. The key distinction of military science fiction from space opera is that the principal characters in a space opera are not military personnel, but civilians or paramilitary. Military science fiction also does not necessarily always include an outer space or multi-planetary setting like space opera. Space Western Westerns influenced early science-fiction pulp magazines. Writers would submit stories in both genres, and science-fiction magazines sometimes mimicked Western cover art to showcase parallels. In the 1930s, C. L. Moore created one of the first space Western heroes, Northwest Smith. After superhero comics declined in popularity in 1940s United States, Western comics and horror comics replaced them. When horror comics became untenable with the Comics Code Authority in the mid-1950s, science-fiction themes and space Westerns grew more popular. and Star Trek presented a new frontier to be explored, and films like Westworld rejuvenated Westerns by updating them with science-fiction themes. Peter Hyams, director of Outland, said that studio heads in the 1980s were unwilling to finance a Western, so he made a space Western instead. Space operas such as the Star Wars film series also took strong cues from Westerns; Boba Fett, Han Solo and the Mos Eisley cantina, in particular, were based on Western themes. These science fiction-films and television series offered the themes and morals that Westerns previously did. == See also ==
