The term Trident for example was given to a ballistic nuclear missile in the 1970's...Here's what wiki says about it...
'The Trident missile is a submarine-launched ballistic missile (SLBM) with multiple independently-targetable reentry vehicle (MIRV) capability. The Fleet Ballistic Missile (FBM) is armed with nuclear warheads and is launched from nuclear-powered ballistic missile submarines (SSBNs). Trident missiles are carried by fourteen active US Navy Ohio class submarines, with U.S. warheads, and four Royal Navy Vanguard class submarines, with British warheads. The original Prime Contractor and developer of the Missile was Lockheed Martin Space Systems in the United States.
Trident - Black on Black Gun Crime Police Unit
Operation Trident or Trident, is a Metropolitan Police Service unit set up to investigate and inform communities of gun crime in London's black community, with special attention being placed on shootings relating to the illegal sale of drugs. The initiative was set up in March (USE OF 3) 1998 by members of the black community following a series of shootings in the London boroughs of Lambeth, Camden and Brent. The Chairperson of the Trident Independent Advisory Group (IAG) is Claudia Webbe. The importance of Trident is such that it was established as a dedicated Operational Command Unit called the Trident Operational Command Unit within the Metropolitan Police Specialist Crime Directorate. In 2004 it expanded with the formation of Operation Trafalgar which investigates all other non-fatal shootings in London. The aim of the campaign is reached via gun amnesties and adverts encouraging people to phone Crimestoppers with information related to gun crime. These adverts appear in the media, nightclubs, on petrol pumps, phone boxes and on the radio. As part of Specialist Crime Directorate, Trident is also known as SCD8 and more recently officers within the command have referred to themselves as "the Ocho". As of 2004 only 16 of the initiative's 300 officers were themselves black.

NOW FOR THE OCCULT DEFINITION;
Various interpretations of the trident or three-pointed spear have been advanced, ranging from Eliade’s suggestion that originally it was a representation of the teeth of sea-monsters (17), to Diel’s explanation which we will discuss below. It is an attribute of Neptune and of Satan. According to Bayley, it is a corrupt form of the cross (4), adapted, that is, in such a way as to suggest a vicious character. More precisely, every instrument, object or being having three members or parts where one would normally suffice realizes a trebling of its symbolic force or potentiality (8). This is born out by Zimmer’s comment that the trident denotes threefold hostility. The third point might well correspond to the third eye of Shiva (or Siva) the Destroyer, since the trident is also an attribute of this god. The fact that the trident was the weapon of the Roman retiarius is highly significant, for the net which he also used relates him to the Uranian deity, whereas the sword wielded by the mirmillo gladiator suggests the heroic, solar son. Hence, the trident, in the hands of the retiarius, would seem to be an attribute of archaic, paternal power opposed to the unique heroism of the solar son.
Diel, with his moralist approach, carries the negative implication of the trident to its logical conclusion, suggesting that it symbolizes triple sin, corresponding to the perversion of the three ‘vital urges’ of nutrition or preservation (transformed into possession, property and authority); reproduction (lust); and spiritualization or evolution (which, in its negative aspect, becomes vanity). Hence it is an attribute of the god of the unconscious and of sin—Neptune, whose realm is the haunt of monsters and base forms of life. The triple character of the trident is an ‘infernal replica of the Trinity’, comparable with the three heads of Cerberus or of triform Hecate (17). On the other hand, a favourable interpretation has also been ascribed to the trident; Charles Ploix, in La Nature et les dieux, associates it with the wand used in water-divining (2), although this interpretation seems to rest on somewhat dubious grounds. According to Father Heras, the trident was, in the proto-Indian era, an attribute of god.
